WARNING!
•You can be badly injured working on or around a
motor vehicle. Do only service work for which you
have the knowledge and the right equipment. If
you have any doubt about your ability to perform a
service job, take your vehicle to a competent me-
chanic.
• Failure to properly inspect and maintain your ve-
hicle could result in a component malfunction and
effect vehicle handling and performance. This
could cause an accident.
MAINTENANCE SCHEDULE — 6.4L
The Scheduled Maintenance services listed in this
manual must be done at the times or mileages specified
to protect your vehicle warranty and ensure the best
vehicle performance and reliability. More frequent main-
tenance may be needed for vehicles in severe operating
conditions, such as dusty areas and very short trip
driving. Inspection and service should also be done
anytime a malfunction is suspected.
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
The message “Oil Change Required” will be displayed in
the DID and a single chime will sound, indicating that an
oil change is necessary.

Based on engine operation conditions, the oil change
indicator message will illuminate. This means that ser-
vice is required for your vehicle. Have your vehicle
serviced as soon as possible, within the next 500 miles
(805 km).
NOTE:
•The oil change indicator message will not monitor the
time since the last oil change. Change your vehicle’s oil
if it has been six months since your last oil change,
even if the oil change indicator message is NOT
illuminated.
• Change your engine oil more often if you drive your
vehicle off-road for an extended period of time.
• Under no circumstances should oil change intervals
exceed 6,000 miles (10,000 km) or six months, which-
ever comes first. 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 “Driver Informa-
tion Display (DID)” in “Understanding Your Instrument
Panel” for further information.
At Each Stop For Fuel
•
Check the engine oil level. Refer to “Maintenance
Procedures/Engine Oil” in “Maintaining Your Ve-
hicle” for further information.
• Check the windshield washer solvent and add if
required.
