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.

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.

At Each Stop For Fuel
• Check the engine oil level. Refer to “Maintenance Procedures/Engine Oil” in
“Maintaining Your Vehicle” for further information.
• Check the windshield washer solvent and add if required.
Once A Month
• Check tire pressure and look for unusual wear or damage.
• Inspect the battery, and clean and tighten the terminals as required.
• Check the fluid levels of the coolant reservoir, brake master cylinder, and power
steering, and add as needed.
• Check all lights and other electrical items for correct operation.
At Each Oil Change
• Change the engine oil filter.
• Inspect the brake hoses and lines.
CAUTION!
Failure to perform the required maintenance items may result in damage to the
vehicle.

MAINTENANCE SCHEDULE — B6 To B20 Biodiesel
NOTE:
• Under no circumstances should oil change intervals exceed 8,000 miles
(12 875 km) or six months, whichever comes first when using Biodiesel blends
greater than 5% (B5).
• The owner is required to monitor mileage for B6-B20 biodiesel, the automatic oil
change indicator system does not reflect the use of biofuels.
