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 indicator message will illuminate.
This means that service is required for your
vehicle. Operating conditions such as fre-
quent short-trips, trailer tow, extremely hot or
cold ambient temperatures will influence
when the “Change Oil” or “Oil Change Re-
quired” message is displayed. Severe Oper-
ating 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 pos-
sible, within the next 500 miles (805 km).
On vehicles equipped with instrument cluster
display, “Oil Change Required” will be dis-
played and a single chime will sound, indi-
cating that an oil change is necessary.
On non-instrument cluster display equipped
vehicles, “Change Oil” will flash in the in-
strument cluster odometer and a single
chime will sound, indicating that an oil
change is necessary.
An 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
an authorized dealer, the message can be
reset by referring to the steps described un-
der “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),
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) or 350 hours of engine run time
if the vehicle is operated in a dusty and off
road environment or is operated predomi-
nately at idle or only very low engine RPM’s.
This type of vehicle use is considered Severe
Duty.

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 reser-
voir, brake master cylinder, and power
steering, and fill as needed

lights
