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.
On non-instrument cluster display equipped
vehicles, “CHANgE OIL” will flash in the
instrument cluster odometer 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 performed. Have your vehicle serviced as
soon as possible, within 500 miles (800 km).
However, an earlier oil change at 4,500 miles
(7,500 km) may be required if the vehicle is
operated under “Severe Duty Conditions”
later in this section.
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
6 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 6 months, whichever comes first.
Your authorized dealer will reset the oil
change indicator message after completing
the scheduled oil change.Once A Month Or Before A Long Trip
• Check the engine oil level about five min-
utes after a fully warmed engine is shut off.
Checking the oil level while the vehicle is
on level ground will improve the accuracy of
the 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.
• 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.
• Inspect the battery and clean and tighten
the terminals as required.
• Check the fluid levels of coolant reservoir,
automatic transmission, brake master cyl-
inder and power steering and fill as needed.
• Check all lights and other electrical items
for correct operation.
