Diesel Engine: Notes

The oil change indicator system will remind you that it is time to take your vehicle in for scheduled maintenance.

On Electronic Vehicle Information Center (EVIC) equipped vehicles, "Oil Change Required" will be displayed in the EVIC and a single chime will sound, indicating that an oil change is necessary.

On Non-EVIC equipped vehicles, "Change Oil" will flash in the instrument cluster odometer and a single chime will sound, indicating that an oil change is necessary.

NOTE:

The oil change indicator message will not monitor the time since the last oil change. Change your vehicles oil if it has been two years since your last oil change and even if the oil change indicator message is NOT illuminated.
Change your engine oil every 10, 000 miles (15 000 km) if you drive your vehicle off-road for an extended period of time.
Under no circumstances should oil change intervals exceed 20, 000 miles (30 000 km) or two years, whichever comes first.

At Each Stop for Fuel

Check the engine oil level and add as required.
Check the windshield washer solvent and add if required.

Once a Month

Check the 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, power steering, and transmission 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 exhaust system.
Inspect the brake linings, hoses, and calipers.
Inspect the CV joints and suspension components.
Check the coolant level, hoses, and clamps.
Inspect the accessory drive belt(s).

CAUTION:

Failure to perform the required maintenance items may result in damage to the vehicle.
Proper operation of four-wheel drive vehicles depends on tires of equal size, type and circumference on each wheel. Any difference in tire size can cause damage to the transfer case. Tire rotation schedule should be followed to balance tire wear.
