MAINTENANCE SCHEDULE — DIESEL ENGINE
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 “Electronic Vehicle Information Center (EVIC)/Oil Change Re-
quired” in “Understanding Your Instrument Panel” for further information
NOTE:
Under no circumstances should oil change intervals exceed 10,000 miles (16,000 km)
or twelve months, whichever comes first.
Engine Oil Filter Replacement
Residual oil in the housing may spill from the housing when the new filter is installed if
the residual oil is not either removed from the housing or enough time has not elapsed
to allow the oil to drain back into the engine. When servicing the oil filter on this engine,
carefully remove the filter and use a suction gun to remove any residual oil left in the
housing or wait about 30 minutes for the oil to drain back into the engine.
