4 Introduction
Protection Against Battery Discharge
In order to prevent battery discharge while
the bus is standing, the Volvo 9700 bus is
equipped with a function that disconnects the
supply to major electrical consumers such
as: the kitchenette, electric heaters, some
external lighting etc.
Power to these consumers is switched off
around 30 seconds after the engine is shut
down, and it is then switched back on once
the engine is started and its revolutions reach
at least 1000 rpm for 10 seconds.
Doors and Hatches 5
Doors
The Volvo 9700 bus could be equipped
with up to two single-leaf doors opening
outwards. The doors are normally operated
by pneumatic cylinders.
The doors may be equipped with a system
protecting passengers from being trapped
in the doorway during opening or closing,
this system has sensors measuring the air
pressure in the door system.
Note: In the case of excessive drop of the
door pneumatic system air pressure, the
“Door failure” warning lamp lights in the
lower right corner of the bus instrument
cluster.

Faults and Warnings
There are three different types of signals that
give the driver all the necessary information
on the vehicle:
•
STOP message
•
warning message
•
information message
Above the display there are three lamps (for
information, warning and STOP messages),
that alert the driver’s attention when
necessary.
Messages with appropriate symbols are
shown automatically on the display.
Several messages can be active
simultaneously. A new message will
only replace the current message on the
display if it is of higher priority. This means
that the display always shows the message
with the highest priority.
For more detailed information about display
functions, see the separate Operating
Instruction “Display”.
Accelerator Pedal Deactivated
The bus is fitted with prioritized brake
function.
This function deactivates a request for
acceleration if both the accelerator pedal and
the foot brake pedal or parking brake have
been activated simultaneously.
The accelerator pedal remains deactivated
until it is reset, which occurs once the pedal
has been fully released.
For additional information on this function,
see the separate Operating Instruction
“Display”.
T0013511
Instruments and Controls 15
STOP Message
WARNING
If this lamp lights while driving, stop
the bus immediately and turn off the
engine. Continuing to drive may severely
endanger the vehicle, the driver and/or
passengers.
Note: If the STOP message appears while
the engine is running, it is accompanied by
activation of the audible warning buzzer.
T3014364
Warning Message
If this lamp lights, the vehicle must be
taken to a workshop for repair as soon as
possible. There is no immediate danger
of the vehicle breaking down, and under
normal circumstances it should be possible to
complete the journey. This lamp is also used
to draw the driver’s attention to problems
other than vehicle failures, e.g. as a warning
in the case of an open luggage compartment
hatch.
T3014365
Information Message
Simultaneously with this lamp lighting up,
a new message is shown on the display.
The fact that this lamp lights up does not
mean that there is something wrong with
the vehicle. This lamp may for example
illuminate to draw the driver’s attention to
low fuel level.

C Turbo pressure gauge
D For the display, see the separate
Operating Instruction “Display”
E Tachometer
F Speedometer
G Fuel gauge
H Air pressure gauge for brakes
Instruments and Controls 17
Oil Pressure Gauge (A)
The oil pressure gauge indicates the engine
oil pressure. While driving with a warm
engine, the pointer should show 3–5 bar
(40–70 psi).
CAUTION
The bus must not be driven when the
pointer is in the red zone! Failure to stop
the vehicle immediately may result in
engine damage.
Note: It is possible that the pointer will
move slightly into the red zone when the
engine is idling while it is warm. This does
not present any danger as long as the pointer
rises above 3 bar (40 psi) when the engine
speed increases.
The following will be indicated if the oil
pressure in the engine drops too low:
– warning lamp (1) lights,
– STOP– lamp lights
– the acoustic signal sounds (if the engine
is running)
CAUTION
If the warning light comes on while
driving; stop the engine and locate the
cause! Failure to do may result in engine
damage.
T0015288
1 Warning lamp, red
18 Instruments and Controls
Engine Coolant Temperature Gauge (B)
This gauge indicates the temperature in the
engine’s coolant system. Under normal
driving conditions, the pointer should stay
just below the red zone (normal operating
temperature is between 80
C (176 F) and
100
C (212 F).
The engine is fitted with overheating
protection, that reduces the engine power
output to 50% if the temperature reaches the
red zone. The bus can still be driven even
after activation of the overheating protection.
CAUTION
The bus must not be driven if the
temperature rises even higher as this can
result in damage to the engine.
An indicator signals when the cooling system
temperature is too high.
– warning lamp (1) lights
– STOP– lamp lights
– the acoustic signal sounds (if the engine
is running)
T0015289
1 Warning lamp, red
Turbo Pressure Gauge (C)
The turbo pressure gauge indicates the
pressure in the intake manifold. A high
turbo pressure increases fuel consumption.
This gauge helps you drive in the most
economical manner. When driving on level
roads at constant speed, the pointer should
remain still within the green zone.
T0011983
Instruments and Controls 19
Display (D)
The display consists of the main menu
and several submenus with their relevant
functions. For additional information, see
the separate Operating Instruction “Display”.
T0012082
Tachometer (E)
The tachometer scale is divided into three
zones. During normal driving you should
stay within the green zone, which gives the
best fuel economy.
CAUTION
Avoid operating the vehicle with the
tachometer in the red zone. Such high
engine speeds can result in damage to the
engine and the transmission.
T0011984
Speedometer (F)
The speedometer indicates the speed of the
bus in mph. For some markets, speedometers
are also available that indicate speed both in
mph and km/h.
T0011985
20 Instruments and Controls
Fuel Gauge (G)
The fuel gauge shows the amount of fuel in
the tank. The red zone and the warning lamp
(1) give a warning of low fuel level.
The display gives considerable information
on the fuel situation, i.e. fuel consumption,
A to B information and remaining fuel.
For more information, see separate driver
instructions “Display”.
T0011986
Air Pressure Gauge for Brakes (H)
DANGER
Stop the bus immediately if any of the
warning lamps illuminate! A warning
lamp will illuminate if there is an
excessive pressure drop in the braking
system. Investigate the cause of the fall
in pressure. Failure to do so may result
in failure of the vehicles brakes that may
cause an accident, leading to serious
personal injury or death.
If the engine remains switched off for a long
time, the compressed air pressure may fall
to a level which will prevent the bus being
started immediately. The warning lamp
remains lit until the pressure in the braking
system rises to a sufficiently high level. If
the compressed air in the braking system has
been completely exhausted, it may take quite
a long time before the pressure starts to rise.
During driving, the gauge pointer should
remain within the green zone, but it can
temporarily drop below that zone during
braking.

Kneeling
This switch allows the right-hand side of the
bus to be lowered (kneeling) to a level that
facilitates passenger entry and exit.
There are two possible operating modes for
the kneeling switch:
1 The bus lowers while the kneeling
switch is depressed. After reaching
the lowest level, i.e. entry/exit level,
kneeling stops and the switch can be
released. Releasing the switch prior to
reaching the lowest level causes the bus
to return to the normal ride height.
2 Pressing the switch once lowers the bus
to its lowest level for entry/exit.
When kneeling function is active, three
icons in the instrument cluster lit and a
blinking lamp is activated at the door as
well a acoustic signal
Various ways to resume normal riding
height:
•
pressing the upper part of the switch
•
closing the doors
•
starting the bus and accelerating beyond
5 km/h (3 mph) road speed (only buses
without door brake)
•

is automatically disengaged on any signs of
the wheels locking. When the retarder is
active, its symbol is shown on the display.
The retarder can be disabled by pressing its
switch on the dashboard.
Note: Under normal driving conditions, the
retarder should not be disabled.

Note: The parking brake is only to be used
for parking or as an emergency brake in case
of malfunction of the foot brake system. The
parking brake only brakes the drive wheels,
the braking distance will be longer than
when using the foot brake. There is also an
increased risk of skidding because only the
drive wheels are used for braking.

Blocking Valve
If the brake system at any point in time
is emptied of air, for example by the bus
standing parked for a longer time period, the
parking brake cannot be released.
To release the parking brake you must first
start the engine and wait until the brake
system warning light has gone out. Then

Service Brakes
The bus is equipped with an EBS brake
system (Electronically-controlled Braking
System). This system monitors and controls
brake operation. For additional information
concerning the EBS system, refer to the
separate Operating Instruction “EBS”.
If the main brakes are used without care
when driving down steep and long inclines,
they will heat up very quickly to extreme
temperatures. The low speed that is generally
the rule in such cases means that the brakes
are not cooled as efficiently as when driving
on level roads.
When driving downhill, in the first instance
use the retarder brake, and only supplement
this with the main brakes as necessary. For
additional information about the retarder, see
“Retarder” page 70.
If you have to use the footbrake while
driving downhill, do not pump the brakes,
as this will only use up compressed air.
Brake sufficiently hard, and then release the
brake pedal completely, or just to the pedal
position where only the retarder is engaged.
Heat builds up very quickly in the brakes,
causing increased wear of the brake linings
and reduced brake efficiency.
This system has a reserve pneumatic system.
The main purpose of the EBS system is to
increase road traffic safety by shortening
braking distances.

EBS controls the ABS and ASR braking
forces. It is fitted only on buses with disc
brakes. ABS is a part of the EBS system
and works completely automatically. The
ABS (Anti-lock Brake System) prevents the
wheels from locking up during braking. In
case of ABS failure, the appropriate symbol
appears on the instrument panel.
Note: ABS efficiency is limited. Remember,
that on slippery surfaces ABS will not
shorten the braking distance significantly. It
can nevertheless help in avoiding obstacles
during braking.

Compensating for Differences in the Wear of the Brake Pads
If the brake pads on one of the axles wear
down faster than those on the other, braking
force is redistributed so that a greater portion
of the braking force is applied to the wheels
on the axle with less wear.
Note: This function activates when braking
lightly. During hard braking the braking
force is distributed so as to achieve the most
efficient braking.
When the thickness of the brake pads is
reduced to 20% of the thickness of new pads,
a warning symbol is shown on the display.
T5013668
DANGER
When brake pad warning symbol is
displayed, immediately proceed to the
nearest service station to replace the brake
pads with new ones. Driving any further
with worn out brake pads may lead to
losing control of the vehicle and cause
an accident resulting in serious personal
injury or death.
Brake temperature High Warning
If the temperature of the brakes increases too
much, the “CHECK” lamp lights, and the
relevant symbol is shown on the display.
Note: If the temperature is allowed to rise

Checking Warning Lights
When the key is in position I, the control
system checks that all the warning lamps are
working properly.
All the warning lamps and the warning LEDs
in the meters are lit for about 5 seconds.
ABS/The ABS system indicator lamp will
light up for slightly longer than the others.
If it continues to be lit then a fault has been
detected in the ABS system./EBS system
discovered
Daily Inspection
Engine oil level, as well as the servofluid and
coolant levels in the bus should be checked
on a daily basis. The checks are carried out
with the engine warm, but switched off.
Note: It is a good idea to do these checks
after a tour as the engine is then at normal
operating temperature.
All tanks are located in the back of the bus.
Engine
When checking the oil level:
•
position the bus on level ground.
•
if the engine is cold, let it idle for 1-2
minutes
•
turn the engine off. Wait at least 2
minutes before carrying out the check
•
remove the dipstick and wipe it with a
clean cloth
•
check the oil level with the dipstick.
The oil level should be between MAX
and MIN
•
top up if necessary.

Open the flap and the fuel filler cover. Insert
the end of the fuel hose into the filler neck.
Fill up the tank. After filling up the tank,
remove the fuel pipe and put it back on the
pump. Close the fuel filler cover and the flap.
Volvo 9700 buses have two tanks with 400
liter (105 gallons) capacity each one.
To open the filler cap press it hard with the
whole palm until its catch releases.
Note: Use only fuel that meets the
manufacturer’s specifications. Avoid spilling
fuel on to painted surfaces. Refuel only at
designated places.
T2022265
Engine Block Heater
An electric engine block heater can be
installed for keeping the coolant hot when
the vehicle is parked. The heater is mounted
through the side of the engine block with the
heater coils in the coolant jacket. The heater
does not interfere with normal operation and
can be permanently installed.
The heater runs on 120V and has an easily
accessible plug, located on the right side of
the engine compartment. The plug will hook
up to a normal extension cable.
T0015492
66 Starting and Driving
Starting the Engine
Starting
When starting the engine, the parking brake
must be engaged and the gear selector must
be in neutral, i.e. N.
Starting a Cold Engine
When starting the engine at temperatures
of around 10
C (50 F) and below, the air
entering the engine should be heated. To
prevent wear and possible damage to the
engine when it is cold, gradually bring it up
to operating temperature before operating
at high engine speeds or full load. After
starting and before moving the vehicle run
the engine at 800 to 1000 rpm for 3 to 5
minutes. Operate at partial engine load
until the coolant temperature reaches 75
C
(167
F).
Proceed as follows:
Turn the ignition key to the position between
II and III. This starts the preheating, which
can take up to about 50 seconds, depending
on the temperature of the coolant. The
indicator lamp is lit during preheating. Once
the lamp has extinguished and the needle
of the temperature gauge has moved off its
lower stop, the engine can be started.
Do not race the engine when it is cold. This
could damage the engine.
CAUTION
Do not let a cold engine run faster than
1000 rpm in very low temperatures (< -20
C (-4 F)). Failure to do so may cause
internal engine damage.
T0014333
Starting and Driving 67
Starting a Hot Engine
Start directly by turning the key to the start
position.
Stopping the Engine
To shut down the engine, turn the key to the
STOP position. In an emergency situation
the engine can be shut down by using the
emergency stop, see “Emergency Stop” page
24.
Note: Before turning off engine. If the
engine has run at high temperature for a
significant time before it is shut down, let the
engine run at idle for 3 minutes to cool the
engine off to avoid heat soak.
Checks After the Engine Has Been Started.
The coolant level warning lamp will stay lit
for a few seconds after the engine has started.
The parking brake warning lamp is lit when
the parking brake is engaged. After releasing
the parking brake, the lamp should remain lit
until the pressure increases to about 540 kPa
(78 psi). The footbrake warning lamp and
the “STOP” lamp should remain lit until the
pressure in the compressed air tanks reach a
sufficiently high level.
DANGER
Do not drive the vehicle until the warning
lamps have gone out, as the brake system
needs the correct air pressure to work
properly. Failure to do so may lead to
an accident, resulting in serious personal
injury or death.
68 Starting and Driving
Idling (programming)
The engine idling speed is 575–625 rpm.
Keeping the idling speed constant is the
task of the electronic control system, which
makes manual adjustment unnecessary.
When the bus is stationary, the idling speed
can be temporarily raised to 1200 rpm.
Low Idle Adjustment
Before you start to adjust the idling speed,
the engine must be warmed up to operating
temperature. The bus must be stationary
with the engine idling.
•
switch (B) must be in the ON position
•
the idling speed is increased by pressing
the “+” side of the SET button (A). Each
press on this button gives an increase
of 10 rpm.
•
if the idling speed becomes too high, it
can be reduced by pressing the “–” side
of the SET button. Each press gives a
decrease of 10 rpm.
Note: The change in idling speed is only
temporary. After pressing a pedal, engaging
a gear or releasing the parking brake, the
idling speed will return to its manufacturer
settings.
If new programming of idling rpm is
required, keep your foot on the brake pedal
and turn off the engine when the new engine
rpm has been set.
Note: If the engine does not “run
smoothly” at the default programmed by the
manufacturer, please visit a Volvo workshop.
T0012078
Starting and Driving 69
Cruise Control
Cruise control is activated by moving the
switch (B) to the ON position.
When the bus reached the desired speed,
press the “+” or “–” side of the SET button
(A). The set speed is increased or decreased
by pressing the “+” or “–” side of the switch
respectively.
If the speed is temporarily increased, e.g. for
overtaking, the vehicle will return to the set
speed when the accelerator is released.
Cruise control is deactivated if:
•
the brake pedal is depressed
•
the retarder stalk is moved to another
position
•
the switch (B) is moved to its OFF
position
After cruise control has been switched off,
the most recent set speed can be restored by
moving the switch (B) to RESUME. This
however does not apply if cruise control has
been deactivated by moving switch (B) to its
OFF position.
T0012078
70 Starting and Driving
Retarder
The function of the retarder is to supplement
the main brake, and it acts as an additional
brake. This function may be based on
an engine brake, or a transmission brake
together with the VEB (Volvo Engine
Brake), which is an exhaust brake combined
with a compression brake.
When the retarder stalk is in its (A) position,
depressing the brake pedal will engage both
the footbrake and the auxiliary brake. This
mode is called “brake blending”, and means
that the brake system decides how great a
contribution to the total braking force will
come from the auxiliary brake, and how
much from the footbrake. It allows for
optimal use of the auxiliary brake.
In other situations (1-3) the bus is braked
by the additional brake as soon as the
accelerator pedal is released. The braking
force is increased by moving the lever down
and decreased by moving the lever up.
Note: The retard function works together
with the EBS system. See the separate driver
instructions for “EBS”.
DANGER
Avoid using the retarder on slippery roads
because of the risk of locking the wheels
and skidding (the retarder brakes only the
driving wheels). Failure to do so may
lead to an accident, resulting in serious
personal injury or death.
T0010263
The (B) position of the stalk is only
present in buses fitted with I-shift.
For additional information, see
the separate Operating Instruction
“I-shift”.
Starting and Driving 71
Speed Limiting
When the bus is driven downhill with the
stalk in position (A), the retarder acts as a
speed limiter. When the bus has reached the
desired speed, lightly press the "+" or "–"
side of the SET button (A). The retarder will
maintain the speed of the bus at the setting it
had when the SET button was pressed.
The set speed can be increased or decreased
by pressing the plus (+) or minus (-) side of
the SET button. Each pressing of the switch
increases or decreases the speed by 1 km/h.
If the switch is held in, the speed is adjusted
by 1 km/h for each second it is held in.
Note: Buses that have a retard switch instead
of a retard lever do not have this function.
T0010263
Use the SET button on the retard
switch to control the speed
limitation.
Combined Cruise Control and Speed Limitation
If the bus is equipped with cruise control
(see “Cruise Control” page 69), the cruise
control system will work together with the
retarder. The stalk of the retarder should be
in position (A).
With cruise control active. While driving
downhill with the cruise control active, the
retarder will be engaged if the road speed
exceeds the set speed by 5 km/h (3 mph).
This overspeed value can be modified by
means of the +/- button to any value in the
range 3–15 km/h (2– 9 mph).
Note: The retarder is automatically
deactivated if there is a risk for wheel
locking.
Note: If the symbol for high retarder
temperature is displayed, a lower gear
range must be selected to cool it down. See
separate Operating Instruction “Display”.
T3008844
72 Starting and Driving
Power Steering
If the wheel is blocked on one side, against
a kerb for example, drive carefully forward
and turn the steering wheel to allow the bus
to move away from the kerb. Never try to
force the wheels to turn.
Do not attempt to turn the bus by using
excessive force on the steering wheel.
Using excessive force on the steering wheel
increases pressure in the power steering
system, causing risk of overheating that may
damage the oil pump.
If the power steering is malfunctioning it
may feel as if the steering gear was blocked,
this is however not the case, but steering the
bus requires the use of much greater force.
T0008960
Starting and Driving 73
Exhaust Aftertreatment System
Volvo 9700 has an exhaust aftertreatment
system which includes a Diesel Particulate
Filter (DPF). The DPF reduces soot and
particulate emissions into the atmosphere.
The DPF takes the place of the standard
muffler. Soot and other particulate matter
are collected by a filter where it is eventually
oxidized using a regeneration process.
Vehicles equipped with a DPF require the
use of EO-O Premium Plus (or VDS-4)
specification high performance diesel engine
oil and Ultra Low Sulfur Diesel (ULSD) fuel.
If the icon “DPF Regeneration
Required”lights on, means that the
diesel particulate filter is becoming full and
regeneration is needed; the icon flashes
when the filter is full, maintain uninterrupted
highway speed for an automatic regeneration
or move the vehicle to a safe location and
initiated a parked regeneration.
The icon “High Exhaust System
Temperature” lights on when a parked
regeneration is initiated. It also indicates
high exhaust gas temperature during an speed
regeneration. When the high exhaust system
temperature icon is light on, do not park
or operate the vehicle near people, or any
flammable materials, vapors, or structures.
For more information about Exhaust
Aftertreatment System, see separated
instruction “Exhaust Aftertreatment
System”.
Note: It is important to enable regeneration
as soon as possible to avoid engine
problems. Long—term engine operation
with regeneration disabled will result in
a loss of engine performance including
horsepower, torque and speed derates.

74 Some Advice for Driving
Safe Driving
1 After starting, and regularly while
driving, check that the instruments are
giving their normal readings. If any
warning lamp lights while driving, stop
the bus and investigate the cause.
2 Never race a cold engine! Avoid idling
for long periods.
3 Never cover the radiator! The
thermostat keeps the temperature
constant regardless of ambient
conditions. Check the coolant level
regularly and use always the correct
type of coolant. Check also hoses/pipes
and tensioning of the belts. Do not
drive with a leaking cooling or heating
system.
4 Never drive off before the brake system
warning lamps have extinguished.
Do not forget the parking brake.
The ABS/EBS indicator lamps may
light, but this only indicates that the
ABS/EBS system is malfunctioning.
5 If one of the front wheels is blocked
sideways, never try to force it to turn by
applying excessive force to the steering
wheel.
6 While driving downhill and for gradual
braking use the retarder function. When
driving in slippery conditions take
special care, or disable the retarder
function altogether.
7 When driving on slippery surfaces, e.g.
in snow or heavy rain, reduce speed and
avoid rapid steering wheel movements.
Brake and accelerate gently, to make
the journey as safe as possible for
the passengers. Driving in slippery
conditions requires extra caution when
there are strong side winds. Side winds
can produce a lifting force acting on the
front axle.
Some Advice for Driving 75
Economy Driving
As the driver, you are the most important
link in the chain for getting the best overall
driving economy.
1 Warm up the engine as quickly
as possible. A warm engine and
transmission uses less fuel than a cold
one (and there is less wear).
2 Treat the accelerator pedal gently.
Do not “pump” the accelerator pedal.
Pumping increases fuel consumption
without increasing the speed. A
turbo pressure gauge helps you drive
economically.
3 High speeds increase fuel
consumption since, among other
things, air resistance increases sharply
with increase of speed. Strong side and
head winds increase fuel consumption
even more.
4 Timely and correct servicing will
keep the bus in good condition. This
will also contribute to preserving low
fuel consumption.
76 Some Advice for Driving
Driving in Cold Weather
Before driving in cold weather conditions
(ambient temperature +40
F[5 C] or
below), pay attention to the following points:
1 The cooling system must be protected
against freezing.
2 The washer fluid tank must be filled
with winter liquid.
3 Batteries must be in good condition.
In low temperatures, the capacity of
batteries to deliver current, e.g. when
starting the engine, drops. Make
sure that the poles of the batteries
are thoroughly clean, with the cable
terminals properly tightened and
covered with grease, and that there is
the correct amount of electrolyte in
every cell.
4 Engine oil, as well as transmission and
rear axle oil, must have the correct
viscosity.
Fill up the tanks with winter fuel. This
reduces the risk of wax settling in the
fuel system. If this has already happened,
change the fuel filters and fill up the tanks
with winter fuel. Keep the tanks as full as
possible.
The compressed air system is particularly
sensitive to low temperatures. Excessive
condensation in the primary tank indicates
that the air drier is not working properly.
Drain the tank and change the desiccator
cartridge in the air drier. If none of these
measures help, use an external heating
source to thaw out the system.
If Something Happens 77
Safety
CAUTION
Always make passenger safety your first
priority !
If something unexpected happens you should
always proceed as follows:
1 Stop the bus in a place which is safe for
the passengers, and where the bus itself
does not constitute an obstacle for other
road users.
2 Open the doors. If necessary use the
emergency valve which is placed in the
vicinity of the door.
3 Let the passengers out.
4 Set the ignition key in position 0.
5 Turn off the power with the main
switch, see “Main Switch” page 24.
6 If necessary, use the emergency stop,
see “Emergency Stop” page 24.
7 If necessary, switch on the warning
lights, see “Hazard Warning Lights”
page 23.
8 Place a warning triangle behind the bus.
Remember that the distance between
the warning triangle and the vehicle
depends on local regulations.
9 Call the service centre and describe the
problem.
78 If Something Happens
If the Engine is Not Working
If the engine refuses to start, check that:
1 The cover of the emergency switch is
folded down.
2 The main power switch on the
dashboard is set to on.
3 The gear selector is in the neutral
position, i.e. N.
4 The parking brake is engaged.
5 The switch in the control box in the
engine bay is turned towards 1.
The engine cannot be started when the
battery voltage is too low (below 18 V).
The engine cannot be started if either the
engine hatch or the front service hatch is
open. In that case the display will show an
appropriate symbol. Close the hatch before
trying to start the engine.
T3018116
Punctures
There are several safety requirements that
need to be considered in the event of a
punctured tire. For detailed information
concerning wheel changing, see the separate
Operating Instruction “Jacking points and
puncture”.
Punctured Air Bellows
In the event of puncture of any of the
suspension air bellows, the speed must be
reduced to 20 km/h (12 mph) and the bus
taken to the nearest service facility.
If Something Happens 79
Towing
CAUTION
Failure to disconnect the driveshaft,
remove the drive axle shaft(s) or lift the
drive wheels off the ground before towing
or pushing the vehicle, can cause serious
transmission damage.
Note: TCS should be turned off if one of the
axles is raised during towing.
For all long distance towing, assure that the
tow vehicle has the necessary equipment to
reach the front axle, per Bus specifications.
Refer to “Technical Specification” page 96
for more information. It may be necessary
for the tow vehicle to attach an air supply
to the bus during towing. Two positions
for attaching are available, one in the front
and another in the rear of the bus. See the
accompanying illustrations for the general
locations.
Towing or moving the bus for short distances
can also be performed using a towing rod or
bar. Refer to the accompanying illustration
for attaching point location.

80 If Something Happens
After mechanically releasing the parking
brake, the bus cannot be braked either with
the main brake or with the parking brake.
Block the wheels or connect to the tow
vehicle, so that the bus cannot start moving
after the parking brake has been released.
Towing requires either the drive shaft or
both drive shafts to be removed, because
otherwise the transmission may be damaged
due to insufficient lubrication.
If the bus has stopped in a unsuitable place
and needs to be moved, it can be towed up to
200 meters (656 ft.) before removal of the
drive shaft/drive shafts.
For, punctures, the tire must be repaired
before towing begins.
Fire
In the event of fire, the STOP lamp lights
up in the engine bay, an audible signal is
emitted and a symbol appears on the display.
DANGER
Shut down the engine immediately!
Failure to due so may keep the radiator
fan running which impels air into the
engine bay and fans the fire. This may
result in serious personal injury or death.
T0012298
If Something Happens 81
Releasing the Parking Brake
Release the Parking Brake with Air from the Bus Tires.
1 To prevent the bus from moving, block
its wheels or attach it to a tow vehicle.
2 Connect the clamp head of the tire
inflation hose to the valve of one of the
tires.
3 Move the parking brake control to the
drive position.
4 While pressing the other end of the tire
inflation hose against the pump nipple,
press in the blocking valve. Now the
brake system is filled with the air from
the tire. Filling can be interrupted as
soon as the air flow stops.
Note: Chock the wheels to prevent the bus
from moving when releasing the parking
brake.
T0009182
82 If Something Happens
Mechanical Releasing of the Parking Brake
1 By blocking the wheels, make sure
that the bus will not start rolling after
releasing the parking brake.
2 On both drive shaft brake cylinders
there are release bolts. Screw them
out until a red plastic button appears
out from the center of the bolt. The
brakes are then released. This requires
around 45 rotations. Use the designated
spanner from the toolkit or the sleeve
and locking handle.
3 The bus can now be towed. Towing
should be performed using a properly
equipped tow vehicle that can reach
the front axle, since the bus is now
completely without brakes.
Note: Do not forget to reset the bolts to their
original position and attach the plastic cover
after towing has been completed.
DANGER
Chock the wheels to prevent the bus from
moving when releasing the parking brake.
Failure to do so may result in serious
personal injury or death.
T5014634
Regarding Disc Brakes
The brake cylinder is fitted with a release
screw, which does not protrude from the
cylinder during manual release. When
starting to release the parking brake, a
red peg emerges from the centre of the
nut. It is fully out after three turns. Full
compression of the parking brake spring
requires approximately 45 turns. Whenever
possible try always to fill the parking brake
cylinders with air. It makes it easier to turn
the nuts of the release mechanisms.
T5014635
If Something Happens 83
Changing the Batteries
When changing batteries, both batteries
should have the same capacity and be of the
same age. When connecting batteries correct
polarity must be observed.
To change a battery:
•
turn off the power with the main switch
•
disconnect the cable terminal from the
negative pole of the battery
•
disconnect the cable terminal from the
positive pole of the battery
•
change the battery
•
clean the cable terminals and both poles
of the battery
•
connect the positive cable terminal to
the battery pole
•
connect the negative cable terminal to
the battery pole
•
apply an anti-corrosive agent to the
poles with terminals
WARNING
Incorrect connection will seriously
damage the electrical system.
If a cable clamp has been incorrectly
installed, the battery terminal must be
reamed to give a sufficiently large mating
surface when correctly installed. Incorrect
installation entails a high risk of oxidation
in the space between the top of the battery
terminal and the battery cable clamp.
T3019198
Top: Mounted incorrectly, terminal
not bottoming on the pole.
Bottom: Mounted correctly,
terminal bottoming on the pole.
84 If Something Happens
Rapid Charging
The bus is equipped with a socket for an
external power supply, located next to the
battery box. Before rapid charging, the main
switch should be turned off to protect the bus
power consumers from power surges.
Note: The rapid charge connector is not
dimensioned for starting assistance.
Note: Only use the rapid charging socket
when the batteries are partially discharged.
If the batteries are completely discharged,
disconnect them from the bus system and
connect directly to a battery charging device.
T0014730
Starting Assistance
In the event that the batteries are unable to
start the engine, auxiliary batteries can be
used to help in starting. These batteries are
connected in parallel with the ordinary bus
batteries.
Note: Note the polarity. Plus to plus and
minus to minus.
CAUTION
Battery chargers with a start boost feature
must not be used for starting assistance.
Failure to do so may cause damage to the
electrical system.
If Something Happens 85
Battery Cut-off Switch
The battery cut-off switch is located next
to the batteries and is there to completely
cut off the bus power supply. To prevent

number, drive and wheelbase. These latter
are not used for buses, only for lorries. The
identification plate is located by the driver’s
seat and contains the following information:
•
G.V.W.R (Gross vehicle weight rating),
is the maximum allowable total weight
of the vehicle.
•
G.A.W.R (Gross axle weight rating), is
the maximum distributed weight that
may be supported by an axle VIN is the
same number that can be found on the
frame member.
•
Tires dimensions.
•
Rims dimensions
•
Cold inflation pressure, is the inflation
pressure of the tires before the vehicle
is driven and the tires warmed up.
•

Service Intervals
Regular servicing in accordance with the
special service schedule is required to
maintain the bus to its original specifications
throughout its service life.
Carry out all servicing and maintenance
of the bus at a Volvo workshop or, for
Prevost support vehicles, in Prevost service
center/provider.
These workshops have the trained personnel,
special tools and necessary service literature
that are vital in ensuring high quality of
servicing. This quality also depends on the
use of Volvo Original Spares, which are of
identical quality to the components installed
at the Volvo works.
For service intervals, see the separate service
literature.
When washing the bus, only use agents
that are intended for this purpose. See
also: Operating Instruction “Interior
maintenance”.
