OIL CHANGE INDICATOR SYSTEM
This vehicle is equipped with an automatic oil change indicator system. The oil change indicator system reminds you that it is time to take your vehicle in for scheduled maintenance.
Based on engine operation conditions, the oil change indicator message will illuminate. This means that service is required for your vehicle. Operating conditions such as frequent short-trips, trailer tow, extremely hot or cold ambient temperatures, and E85 fuel usage will influence when the “Oil Change Required” message is displayed. Severe Operating Conditions can cause the change oil message to illuminate as early as 3,500 miles (5,600 km) since last reset. Have your vehicle serviced as soon as possible, within the next 500 miles (805 km).
On the Electronic Vehicle Information Center (EVIC) equipped vehicles “Oil Change Required” is displayed in the EVIC and a single chime sounds indicating that an oil change is necessary.
On non-EVIC equipped vehicles “Change Oil” flashes in the instrument cluster odometer and a single chime sounds indicating that an oil change is necessary.
NOTE:Under no circumstances should oil change intervals exceed 10,000 miles (16 000 km) or twelve months, whichever comes first.
Once A Month Or Before A Long Trip:
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
- 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 (2500/3500 models only) and transmission as needed
- Check function of all interior and exterior lights
CAUTION:Failure to perform the required maintenance items may result in damage to the vehicle.
OIL CHANGE INDICATOR - RESET
- 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.
- Lube the front drive shaft fitting (2500/3500 (4x4) models only).
The vehicle is equipped with an engine oil change indicator system. The “Oil Change Required” message flashes in the EVIC display for approximately ten seconds after a single chime has sounded, to indicate the next scheduled oil change interval. The engine oil change indicator system is duty cycle based, which means the engine oil change interval may fluctuate depending upon your personal driving style.
Unless reset, this message continues to display each time you turn the ignition switch to the ON/RUN position. To turn off the message temporarily, press and release the Menu button. To reset the oil change indicator system (after performing the scheduled maintenance) perform the following procedure:
NOTE:If the indicator message illuminates when you start the vehicle, the oil change indicator system did not reset. If necessary, repeat this procedure.
