MAINTENANCE SCHEDULE
The Scheduled Maintenance services listed in this
manual must be done at the times or mileages specified
to protect your vehicle warranty and ensure the best
vehicle performance and reliability. More frequent main-
tenance may be needed for vehicles in severe operating
conditions, such as dusty areas and very short trip
driving. Inspection and service should also be done
anytime a malfunction is suspected.
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.
On Electronic Vehicle Information Center (EVIC)
equipped vehicles, “Oil Change Required” will be dis-
played 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.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that ser-
vice 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 “Change Oil” message is displayed.
Depending on operating conditions, the message may
appear as early as 3,500 miles (5 630 km) since last reset.
Have your vehicle serviced as soon as possible, within
the next 500 miles (805 km).
