SERVICING AND MAINTENANCE
SCHEDULED SERVICING

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 indi-
cator 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).

Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a sched -
uled oil change is performed by someone other than your autho-
rized dealer, the message can be reset by referring to the steps
described under “Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further information.
Gasoline Engines:
Under no circumstances should oil change intervals exceed
8,000 miles (13,000 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:
Change Engine Oil at 4,000 miles (6,500 km) or 350 hours of
engine run time if the vehicle is operated in a dusty and off
road environment or is operated predominately at idle or
very low engine RPM’s. This type of vehicle use is consid
-
ered Severe Duty.
