MAINTENANCE SCHEDULE
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 condi-
tions such as frequent short-trips, trailer tow, extremely
hot or cold ambient temperatures, and E85 fuel usage
will influence when the “Change Oil” message is dis-
played. 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 indica-
tor 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 “Instru-
ment Cluster Display” in “Understanding Your Instru-
ment Panel” for further information.NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km), twelve
months or 350 hours of engine run time, whichever
comes first. The 350 hours of engine run or idle time is
generally only a concern for fleet customers.
Severe Duty All Models
Change Engine Oil at 4,000 miles (6,500 km) if the
vehicle is operated in a dusty and off road environment
or is operated predominately at idle or only very low
engine RPM’s. 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 and brake
master cylinder as needed.
Check function of all interior and exterior lights.
