Oil Change Indicator System
Your vehicle is equipped with an automatic oil change indicator system. The oil change indicator system will remind 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 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).
Your authorized dealer will reset the oil change indicator message after completing the scheduled oil change. If a scheduled oil change is performed by someone other than your authorized dealer, the message can be reset by referring to the steps described under "Oil Change Reset" in "Electronic Vehicle Information Center (EVIC)" or "Driver Information Display (DID)" in "Understanding Your Instrument Panel" for further information.
Under no circumstances should oil change intervals exceed 10, 000 miles (16, 000 km) or twelve months, whichever comes first.
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.
