WARNING!
Measurement of vehicle statistics with the Performance Features is intended for
off-highway or off-road use only and should not be done on any public roadways.
It is recommended that these features be used in a controlled environment and
within the limits of the law. The capabilities of the vehicle as measured by the
performance pages must never be exploited in a reckless or dangerous manner,
which can jeopardize the user’s safety or the safety of others. Only a safe,
attentive, and skillful driver can prevent accidents.

DIESEL ENGINE BREAK-IN RECOMMENDATIONS
The diesel engine does not require a break-in period due to its construction. Normal
operation is allowed, providing the following recommendations are followed:
• Warm up the engine before placing it under load.
• Do not operate the engine at idle for prolonged periods.
• Use the appropriate transmission gear to prevent engine lugging.
• Observe vehicle oil pressure and temperature indicators.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds when carrying or towing significant
weight.
NOTE:
Light duty operation such as light trailer towing or no load operation will extend the
time before the engine is at full efficiency. Reduced fuel economy and power may be
seen at this time.
The engine oil installed in the engine at the factory is a high-quality energy conserving
type lubricant. Oil changes should be consistent with anticipated climate conditions
under which vehicle operations will occur. NON-DETERGENT OR STRAIGHT MINERAL
OILS MUST NEVER BE USED.
DIESEL ENGINE STARTING PROCEDURES
Normal Starting Procedure
1. Apply the parking brake.
2. Ensure the shift lever is in the PARK position.
3. Press and hold the brake pedal while pressing the ENGINE START/STOP button
once.
4. The system will take over and attempt to start the vehicle. If the vehicle fails to
start, the starter will disengage automatically after 30 seconds.
5. If you wish to stop the cranking of the engine prior to the engine starting, press the
button again.
6. Check that the oil pressure warning light has turned off.
7. Release the parking brake.
NOTE:
A delay of the start-up can be as long as five seconds under very cold conditions. The
"Wait to Start" telltale will be illuminated during the pre-heat process and the start
will commence upon the telltale going out.

• The ESC system will make buzzing or clicking sounds when it is active. This is
normal; the sounds will stop when ESC becomes inactive following the maneuver
that caused the ESC activation.
• To improve the vehicle's traction when starting off in deep snow, sand or gravel, it
may be desirable to switch the ESC system to Partial Off mode by momentarily
pressing the ESC Off
switch located below the climate controls, on the switch
panel.
- Electronic Stability Control (ESC) OFF Indicator Light
This light indicates the Electronic Stability Control (ESC) is off.
- Charging System Light
This light shows the status of the electrical charging system. If the charging system
light remains on, it means that the vehicle is experiencing a problem with the
charging system.
We recommend you do not continue driving if the charging system light is on. Have
the vehicle serviced immediately.
- Oil Pressure Warning Light
This light indicates low engine oil pressure. If the light turns on while driving, stop
the vehicle and shut off the engine as soon as possible. A chime will sound for four
minutes when this light turns on.
We recommend you do not operate the vehicle or engine damage will occur. Have the
vehicle serviced immediately.
- Anti-Lock Brake (ABS) Light
This light monitors the Anti-Lock Brake System (ABS). The light will turn on when the
ignition switch is turned to the ON/RUN position and may stay on for as long as four
seconds.
If the ABS light remains on or turns on while driving, it indicates that the Anti-Lock
portion of the brake system is not functioning and that service is required. However,
the conventional brake system will continue to operate normally if the BRAKE
warning light is not on.
If the ABS light is on, the brake system should be serviced as soon as possible to
restore the benefits of Anti-Lock brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON/RUN position, have the light inspected by an
authorized dealer.
WHAT TO DO IN EMERGENCIES
154

Severe Duty All Models
Change Engine Oil at 4000 miles (6,500 km) if the vehicle is operated in a dusty and
off road environment. This type of vehicle use is considered Severe Duty.
Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual wear or damage
• Check the fluid levels of the coolant reservoir, brake master cylinder, power
steering and transmission as needed
• Check function of all interior and exterior lights
Required Maintenance
Refer to the Maintenance Schedules on the following pages for required mainte-
nance.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
•
Change oil and filter.
• Rotate the tires.Rotate at the first sign of irregular wear, even if it occurs before the oil
indicator system turns on.
•
Inspect battery and clean and tighten terminals as required.
•
Inspect automatic transmission fluid if equipped with dipstick.
•
Inspect brake pads, shoes, rotors, drums, hoses and park brake.
•
Inspect engine cooling system protection and hoses.
•
Inspect exhaust system.
•
Inspect engine air cleaner if using in dusty or off-road conditions.
