SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Your vehicle is equipped with an automatic oil
change indicator system. The oil change indi-
cator 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
“Change Oil” or “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).
On vehicles equipped with instrument cluster
display, “Oil Change Required” will be displayed
and a single chime will sound, indicating that an
oil change is necessary.
On non-instrument cluster display equipped
vehicles, “Change Oil” will flash in the instru-
ment cluster odometer and a single chime will
sound, indicating that an oil change is neces-
sary.
An authorized dealer will reset the oil change
indicator message after completing the sched-
uled oil change. If a scheduled oil change is
performed by someone other than an autho-
rized dealer, the message can be reset by refer-
ring to the steps described under “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km),
12 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) 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 only very
low engine RPM. This type of vehicle use is
considered Severe Duty.
Once A Month Or Before A Long Trip:
Check the engine oil level.
Check the windshield washer fluid level.
Check the tire inflation pressures and look
for unusual wear or damage, rotate at the
first sign of irregular wear.
Check the fluid levels of the coolant reservoir,
brake master cylinder, and power steering,
and fill as needed.
Check the function of all interior and exterior
lights.
