Engine Oil Additives
Don't add anything to your oil. Your dealer is ready to
advise if you think something should be added.
When to Change Engine Oil
Your vehicle has an Oil Life Monitor. This feature
will let you know when to change your oil and
filter
--
usually between 3,000 miles (5 000 km) and
7,500
miles (12 500 k m )
since your last oil change.
Under severe conditions, the indicator may come on
before 3,000 miles (5 000
km).
Never drive your vehicle
more than 7,500 miles (12 500
k m )
or 12 months
(whichever occurs first) without an oil change.
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. Remember to reset
the CHG OIL SOON light when the oil has been
changed. For more information, see "CHG OIL SOON
Light" in the Index.
How to Reset the CHG OIL SOON Light
Remember, after changing your engine oil, the system
must be reset; with the ignition key in RUN, but the
engine off, fully push and release the accelerator pedal
three times within five seconds. If the CHG OIL SOON
light flashes two times, the system is reset. However if
the light comes on and stays on for five seconds, it did
not reset. You'll need to reset the
system again.
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.
