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 perfor-
mance and reliability. More frequent maintenance may be
needed for vehicles in severe operating conditions, such as
498 MAINTENANCE SCHEDULES

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.
A “Oil Change Required” message will be displayed in the
instrument cluster and a single chime will sound, indicat-
ing that an oil change is necessary.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that service
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/track usage for an extended period of
time. •
Under no circumstances should oil change intervals
exceed 6,000 miles (10,000 km) or six months, whichever
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 “Instrument Cluster
Display” 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 Vehicle”
for further information.
• Check the windshield washer solvent and add if re-
quired.
Once A Month
• Check tire pressure and look for unusual wear or
damage.
• Inspect the battery, and clean and tighten the terminals
as required.
