MAINTENANCE PROCEDURES
For information on the maintenance procedures for your vehicle, please refer to
“Maintenance Procedures” in “Maintaining Your Vehicle” in your Owner’s Manual or
applicable supplement on the DVD for further details.
MAINTENANCE SCHEDULE
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 “Change Oil” or “Oil Change Required” message is dis-
played. 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 Electronic Vehicle Information Center (EVIC) equipped vehicles, “Oil Change
Required” will be displayed 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.
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 “Instrument Cluster Warning Lights” in “What To Do In Emergen-
cies” in this guide or “Instrument Cluster Descriptions” or “Electronic Vehicle
Information Center (EVIC)” in “Understanding Your Instrument Panel” in the
Owner’s Manual on your DVD 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) if the vehicle is operated in a dusty
and off road environment or is operated predominately at idle or only very low engine
RPM’s. This type of vehicle use is considered Severe Duty.
