SCHEDULED SERVICING
3.6L And 5.7L Engines
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, and E85 fuel usage 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 (800 km).
The “Oil Change Required” message will be displayed in
the instrument cluster 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 thanyour authorized dealer, the message can be reset by
referring to “Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further information.
NOTE:
Under no circumstances should oil change inter-
vals 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 predominantly at idle
or only very low engine RPM’s. This type of vehicle use is
considered Severe Duty.
Once A Month Or Before A Long Trip:
• Check engine oil level.
• Check windshield washer fluid level.
• Check tire pressure and look for unusual wear or
damage. Rotate tires at the first sign of irregular wear,
even if it occurs before your next scheduled service.

vehicle handling and performance. This could cause
an accident.
Heavy Duty Use Of The Vehicle
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’s. This type of vehicle use is
considered Severe Duty.
6.4L Engine
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 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 (800 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.

SERVICING AND MAINTENANCE 335

Tread Wear Indicators
Tread wear indicators are in the original equipment tires to
help you in determining when your tires should be re-
placed.
These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes a 1/16 of an inch (1.6 mm). When the tread isworn to the tread wear indicators, the tire should be
replaced. Refer to “Replacement Tires” in this section for
further information.
Life Of Tire
The service life of a tire is dependent upon varying factors
including, but not limited to:
•
Driving style.
• Tire pressure - Improper cold tire inflation pressures can
cause uneven wear patterns to develop across the tire
tread. These abnormal wear patterns will reduce tread
life, resulting in the need for earlier tire replacement.
• Distance driven.
• Performance tires, tires with a speed rating of V or
higher, and Summer tires typically have a reduced tread
life. Rotation of these tires per the vehicle scheduled
maintenance is highly recommended.
WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire failure.
