Foreword

This PREVOST XLII Owner's Manual featuring

the new Volvo D13 engine available on XLII-45E

Entertainer coaches only, the new Allison

transmission shift selector and the new optional

Automatic Fire Detection and Suppression

System (AFSS) has been prepared to

thoroughly acquaint you, the owner, with

vehicle’s equipment and features in order to fully

appreciate and safely enjoy your vehicle. Of

course, you are anxious to drive your new

private motorcoach and test its features, but first

please read this publication carefully to help

ensure enjoyable and trouble free operation.

This book should be kept inside the vehicle at all

times for convenient reference. It is also

suggested that it remains with the vehicle at the

time of resale. Please notify PREVOST when

the vehicle's ownership is transferred so that our

records can be kept up to date. Do this by filling

out the appropriate form at the end of this

manual.

The specifications, descriptions and figures

given are based on the latest information

available at printing time. And because at

PREVOST we are constantly striving to improve

our products, we reserve the right to make

changes at any time without notice and/or

obligation on our part.

Please note that this publication applies to

factory-prepared, conversion-ready luxury

motorcoaches, manufactured by PREVOST. It

describes and explains the equipment and

options available for installation in our factory.

Therefore, there may be equipment described

herein that is not installed on your vehicle. This

publication also does not cover equipment

installed by your interior designer or system

manufacturer.

This manual, or portions thereof, cannot be

reproduced in any form whatsoever, in whole or

in part, without the written consent of

PREVOST.

The following words are used to emphasize

particularly important information:

DANGER

Directs the operator’s attention to unsafe

practices which could result in serious

personal injury or death.

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.

For your own safety and to ensure prolonged

service life of your private motorcoach, heed our

warning labels: DANGER, WARNING,

CAUTION and NOTE. Ignoring them could result

in extensive damage and/or serious personal

injury.

Safety Precautions

2

To ensure safe and reliable operation, heed the

following safety precautions.

SAFE OPERATING PRACTICES

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 the safety belt when driving.

o Check the instrument panel frequently. Do

not operate the vehicle when dials or

indicators are not in their normal operating

condition.

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 a vehicle

equipped with an automatic transmission.

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.

o Do not use the trailer hitch before reading

the safety, technical and operational

requirements on page 14 of this manual.

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.

Safety Precautions

3

OTHER PRECAUTIONS

DANGER

Prior to working on a system inside the

vehicle, make sure to cut electrical power and

air supply. A component could be supplied

with electricity even if battery master 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.

CAUTION

Prior to welding or soldering on the vehicle,

disconnect all electronic modules, positive

and negative battery connections. If these

modules (MCM, CPC or VECU, TCM, ECU,

ABS) are not disconnected, electronic

components (EPROM, CHIPS) could be

permanently damaged.

Refer to Section 00 of your maintenance

manual for all related procedures.
