If none of them is true, use the long trip/highway
maintenance schedule. Change the oil and filter every
7,500 miles (12 500 km) or 12 months
-- whichever
occurs first. Driving a vehicle with a fully warmed
engine under highway conditions causes engine oil to
break down slower.
How to Reset the Engine Oil Life Monitor (Option)
After changing the engine oil, the Engine Oil Life
Monitor should be reset. It will not reset itself. This will
cause the CHANGE OIL SOON light to be lit for a bulb
check period of three seconds. Refer to ªEngine Oilº in
the Index to determine what type of oil to use.
To reset the Oil Life Monitor, the ignition key must be
in RUN. Press and hold the OIL RESET button (located
in the glove box) for at least five seconds but not more
than 60 seconds. After five seconds, the CHANGE OIL
SOON light will flash four times and then go off. This
indicates that the Engine Oil Life Monitor System has
been reset.
What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don't let used oil stay on your skin
for very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil.
(See the manufacturer's warnings about the use and
disposal of oil products.)
Used oil can be a real threat to the environment. If you
change your own oil, be sure to drain all free
-flowing oil
from the filter before disposal. Don't ever dispose of oil
by putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used oil.
If you have a problem properly disposing of your used
oil, ask your dealer, a service station or a local recycling
center for help.

The system won't detect dust in the oil. So if you
drive in a dusty area be sure to change your oil every
3,000 miles (5 000 km) or sooner if the CHANGE OIL
SOON light comes on. Remember to reset the Oil Life
Monitor when the oil has been changed. For more
information, see ªCHANGE OIL SOON Lightº in
the Index.
+ A good time to check your brakes is during tire
rotation. See ªBrake System Inspectionº under ªPeriodic
Maintenance Inspectionsº in Part C of this schedule.++ If you drive in a highly corrosive environment, your
brake calipers may require additional inspection and
service, at every other tire rotation. See
ªCaliper/Knuckle Maintenance Inspectionº under
ªPeriodic Maintenance Inspectionsº in Part C of
this schedule.
