ii FOREWORD

CRITICAL EMISSION-RELATED MAINTENANCE

Source of parts and repair:

A repair shop or person of the owner’s choosing must maintain, replace, or repair emission control

devices and systems per manufacturer's recommendations.

Replacement of tires that are GHG certified:

The original equipment tires installed on this vehicle at the factory were certified to the U.S. EPA

Greenhouse Gas (GHG) and National Highway Traffic Safety Administration (NHTSA) Fuel

Efficiency regulations. Replacement of these tires should

be with

a tire of equal or lower rolling

resistance levels (TRRL or Crr). Please consult your tire supplier(s) for appropriate replacement tires.

Maintaining a GHG certified tire:

In order to maintain the certified rolling resistance of the tires which optimize fuel economy, the

maintenance procedures provide by the tire manufacturer must be followed.

EVENT DATA RECORDING DEVICES

This PREVOST vehicle is equipped with a device generally referred to as an "event data recorder" or

"EDR." Please note that while the term "event data recorder" is typically used throughout the motor

vehicle industry, not every EDR is the same; i.e., they do not all record the same data elements.

The EDR on this PREVOST vehicle records vehicle speed, engine RPM, time and date, plus a variety of

pedal and switch positions, both before and after an "event." Sudden vehicle deceleration or the

occurrence of certain other vehicle operational characteristics will define (trigger) an "event."

For any questions about this vehicle EDR device, contact a PREVOST Service Center or a regional

service manager.

1-2 SAFETY PRECAUTIONS

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.

DANGER

Make sure that electrical current or air

pressure is removed before performing any

work. A part may be energized even if the

ignition switch is OFF. A part may be under

pressure even if all tanks are empty. Before

performing any work on the vehicle, refer to

wiring diagrams and/or air schematics to

thoroughly understand the system.

NOTE

When the ignition switch is set to the OFF

position, the electrical components are not

energized except for the MCM (Master

Chassis 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 MCM

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
