FOREWORD 1

This Operator's Manual for the PREVOST H3-

41 and H3-45 coaches has been prepared to

thoroughly acquaint you, the driver, with the

equipment and features of the coach in order for

you to fully appreciate and safely enjoy this

vehicle. Prevost Car Incorporated is committed

to the continuous improvement of coach quality,

reliability, durability and safety. With innovative

features, the H3 series coach was designed with

passenger and driver safety and comfort in mind.

This manual contains information available at the

time of publication. Because standard and

optional equipment is covered in this manual,

some of the optional equipment described may

not apply to your coach. If in doubt, refer to the

technical documentation package provided with

the coach.

Driver's controls and instruments incorporate

advanced technology for enhanced driving ease

and security. This manual describes the main

features, instruments and controls, and servicing

requirements for both standard and optional

equipment. Read this manual carefully to take

advantage of the coach's advanced features and

to ensure optimum safety and passenger comfort.

Keep this manual in the coach at all times. Make

sure this manual is kept with the coach when

ownership is transferred. Please use the

appropriate card at the end of this manual to

promptly notify Prevost Car of any change of

address or transfer of ownership. This will ensure

we provide fast and reliable coach service to all

coach operators.

Warnings, cautions and notes are used

throughout this manual to emphasize important

points when necessary:

WARNING

Directs the operator’s attention to unsafe

practices which could result in serious

personal injury or severe damage to the

vehicle.

CAUTION

Directs the operator’s attention to unsafe

practices where personal injury is not likely

but damage to vehicle components could

occur.

NOTE

Indicates supplementary information essential

to the proper operation of the vehicle.

The service life of the coach depends on the kind

of attention it receives. Pay close attention to the

warnings, cautions and notes. Read the various

notices and instructions posted throughout the

coach and attached to equipment.

Since continuous improvement is a primary focus at Prevost

Car, we reserve the right to make changes anytime, without

notice, and without incurring any obligation.

Before reproducing or copying this manual, in whole or in

part, written consent must be obtained from Prevost Car

Incorporated.

SAFETY PRECAUTIONS 3

SAFE OPERATING PRACTICES

To ensure safe and reliable operation, heed the

following safety precautions.

o Operation and maintenance of the vehicle

must be performed only by qualified

personnel.

o Before driving, conduct a walk around

inspection and check that all baggage

compartment doors and equipment access

doors are securely shut.

o Make sure good visibility is maintained at all

times. Keep windshields clean and free of

obstructions.

o Adjust the driver's seat so that all controls

can be reached easily.

o Always wear your safety belt when driving.

o Check the instrument panel frequently. Do

not operate the vehicle when dials or

indicators do not indicate normal operating

conditions.

o Always pay attention to pedestrians passing

in front and behind the vehicle. Always yield

to pedestrians at pedestrian walkways.

o Do not drive over obstacles on the road.

Empty boxes, piles of leaves, and snowdrifts

could conceal hidden dangers that could

damage the vehicle suspension and

underbody.

o When turning or changing lanes, signal your

intention well in advance.

o When approaching to make a right turn,

reduce the space between the vehicle and

the curb to make sure another vehicle

cannot pass on the right. Since the vehicle

makes wide turns, allow enough space to

make safe turns.

o Switch from high beams to low beams when

meeting or following other vehicles within

500 feet (150 meters).

o Never leave the vehicle unattended with the

engine running or with the key in the ignition.

Turn off the engine, remove keys and apply

the parking brake before leaving the vehicle.

o Shut-off the engine before refueling, adding

oil, performing maintenance or servicing

tasks, unless stated otherwise.

o Fuel is highly flammable and explosive. Do

not smoke when refueling. Keep away from

open flames or sparks.

o Do not run the engine or HVAC system with

access doors left open. Close compartment

doors before operating any equipment.

o Do not remove the surge tank filler cap or

the cooling system pressure cap when the

engine is hot. Let the engine cool down

before removing filler caps.

o Do not attempt to push or pull-start the

vehicle.

o The service life of the vehicle depends on

the kind of maintenance it receives. Always

record any problems and report them

immediately to maintenance personnel. After

each trip, perform a system diagnostic to

check if error codes and anomalies were

recorded in the vehicle electronic modules.

DEFENSIVE DRIVING PRACTICES

o For city driving, allow a four to six second

travel interval between your vehicle and the

vehicle ahead. Increase this travel interval

to six to eight seconds for highway driving.

Increase time interval for driving at night or

in foul weather.

o Be prepared to stop when approaching an

intersection. The stopping distance of the

vehicle increases with the weight and speed.

o Establish eye-to-eye contact with other

drivers and with pedestrians. Use, high

beam and low beam headlights, turn signals

and horn as needed.

o On highway, don't stare at the road ahead.

Keep your eyes moving. Check mirrors and

dashboard instruments frequently.

o To keep the vehicle from drifting across

lanes during highway driving, always look

over the horizon on the road ahead.

o Adjust your speed to road conditions, traffic

and visibility. Never exceed the posted

speed limits.

o If another vehicle is following close behind,

reduce your speed to let the vehicle pass.

For additional information about safe operation

and defensive driving practices, contact the local

department of motor vehicles authority.

4 SAFETY PRECAUTIONS

OTHER PRECAUTIONS

WARNING

Prior to working on a system inside vehicle,

make sure to cut electrical power and air

supply. A component could be supplied with

electricity even if the ignition switch is set to

the OFF position and/or a component could

be pressurized even if air tanks are emptied.

Always refer to the appropriate wiring and

pneumatic diagrams prior to working on

electrical and/or pneumatic systems.

NOTE

When the ignition switch is set to the OFF

position, the electrical components are not

energized except for the CECM (Chasis

Electronic Control Module), the battery

equalizer, the preheater system and some

electronic modules; which are energized during

15 minutes after the ignition has been set to

the OFF position. Prior to working on one of

these electrical components, set the battery

master switch in the main power compartment

to the OFF position. If the vehicle will not be

operated for a long period (more than 2

weeks), it is recommended, in order to prevent

the batteries from discharging, to trip the main

circuit breakers located in the main power

compartment to stop the small current drawn

by the radio preset station memory, the CECM

memory and the instrument cluster clock. Note

that the radio station presets will be erased,

same thing for the diagnostic codes history and

the instrument cluster clock will have to be

reset.

CAUTION

Prior to arc welding on the vehicle, refer to

section 00-GENERAL of your maintenance

manual. Precautions have to be taken to

avoid costly damage to the electronic

components.
