SCHEDULED SERVICING
Scheduled Servicing — Gasoline Engine
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.
An “Oil Change Required” will be displayed
in the instrument cluster and a single chime
will sound, indicating that an oil change is
necessary.
The oil change indicator message will illumi-
nate approximately 7,000 miles (11,200 km)
after the most recent oil change was per-
formed. Have your vehicle serviced as soon as
possible, within 500 miles (800 km).
NOTE:
• The oil change indicator message will notmonitor the time since the last oil change.
Change your vehicle’s 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. 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 the oil indicator system turns on.
• Check the fluid levels of the coolant reser- voir and brake master cylinder, fill as
needed.
• Check function of all interior and exterior lights.
