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.

SAFETY PRECAUTIONS 1-3

OTHER PRECAUTIONS

WARNING

This vehicle is not designed to carry standing

passengers.

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.
