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 engine oil replacement.
On vehicles equipped with instrument cluster
display, “Oil Change Required” will be displayed
and a single chime will sound, indicating that an
oil change is necessary.
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.
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 will influence when the
“Oil Change Required” message is displayed.
Severe Operating Conditions can cause the
change oil message to illuminate earlier than
specified. Have your vehicle serviced as soon as
possible, within the next 500 miles (805 km).
NOTE:

The actual interval for changing engine oil
and replacing the engine oil filter depends on
the vehicle usage conditions, and is signaled
by the warning light or message in the instru-
ment panel. In any case, it must never
exceed 12,500 miles (20,000 km) or one
year.

Flush and replace the engine coolant at
120 months or 150,000 miles (240,000 km)
whichever comes first.

The maximum mileage is 75,000 mi
(120,000 km). The belt must be replaced every
five years regardless of distance traveled. The
timing and accessory belts must be changed
every 37,500 miles (60,000 km) or three years
for particularly demanding use (dusty areas,
severe weather conditions, very low or very high
temperatures for extended periods, city driving,
long periods of idling). Under no circumstances
should these intervals be exceeded.
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 reservoir
and brake master cylinder, fill as needed.

Check function of all interior and exterior
lights.
