MAINTENANCE SCHEDULE
Maintenance Schedule – Gasoline
Engine
The Scheduled Maintenance services listed in
this manual must be done at the times or
mileages specified to protect your vehicle war-
ranty and ensure the best vehicle performance
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 sched-
uled maintenance.
On Electronic Vehicle Information Center
(EVIC) equipped vehicles “Oil Change Re-quired” will be displayed in the EVIC 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 not
monitor the time since the last oil change.
Change your vehicles 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 ex-
tended 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 sched-
uled oil change. If this scheduled oil change is
performed by someone other than your autho-
rized dealer the message can be reset by
referring to the steps described under ”Elec-
tronic Vehicle Information Center” in “Under-
standing Your Instrument Panel” for further in-
formation.
