SCHEDULED SERVICING
Scheduled Servicing — Non SRT
The scheduled services listed in this manual
must be done at the times or mileages speci-
fied to protect your vehicle warranty and
ensure the best vehicle performance and re-
liability. More frequent maintenance may be
needed for vehicles in severe operating con-
ditions, such as dusty areas and very short
trip driving. Inspection and service should
also be done anytime a malfunction is sus-
pected.
The oil change indicator system will remind
you that it is time to take your vehicle in for
scheduled maintenance.
In the instrument cluster an “Oil Change
Required” message will be displayed and a
single chime will sound, indicating that an oil
change is necessary.
The oil change indicator message will illuminate
approximately 7,000 miles (11,200 km) after
the most recent oil change was performed. Have
your vehicle serviced as soon as possible, within
500 miles (800 km).
NOTE:
•
The oil change indicator message will not moni-
tor the time since the last oil change. Change
your vehicles oil if it has been 12 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 7,500 miles (12,000 km)
or 12 months, whichever comes first.
Your authorized dealer will reset the oil
change indicator message after completing
the scheduled oil change. If this 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 “Get-
ting To Know Your Instrument Panel” for
further information.
At Each Stop for Fuel
• Check the engine oil level about 5 minutes
after a fully warmed engine is shut off.
Checking the oil level while the vehicle is
on level ground will improve the accuracy ofthe oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
• Check the windshield washer solvent and
add if required.
Once a Month
• Check tire pressure and look for unusual
wear or damage. Rotate tires at the first
sign of irregular wear.
• Inspect the battery and clean and tighten
the terminals as required.
• Check the fluid levels of the coolant reser-
voir, and brake master cylinder; add fluid as
needed.
• Check all lights and other electrical items
for correct operation.
At Each Oil Change
• Change the engine oil filter.
• Inspect the brake hoses and lines.
CAUTION!
Failure to perform the required maintenance
items may result in damage to the vehicle.
