The oil light could come on briefly when you turn your
key to RUN. It goes off once you turn it to START.
That's just a check to be sure the light works. If it
doesn't, be sure to have it fixed so it will be there to
warn you if something goes wrong.
But, when this light comes on and stays on, it means oil
isn't going through your engine properly. You could be
low on oil, or you might have some other oil problem.
See your dealer for service.
CAUTION:
Don't keep driving if the oil pressure is low.
If you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.
Check Oil Level Light (If Equipped)
The CHECK OIL LEVEL
light turns on for three
seconds as a bulb check
each time the ignition key is
turned to RUN. If the light
doesn't turn on, have your
vehicle serviced.
If the engine oil is more than one quart (0.95 L) low and
the engine has been shut off for at least eight minutes,
the CHECK OIL LEVEL light will turn on for about
one minute and will then remain off until the next time
you start the vehicle.
If the CHECK OIL LEVEL light turns on, the engine oil
should be checked at the dipstick then brought up to the
proper level if necessary. See ªEngine Oilº in the Index.

Engine Oil
If the CHECK OIL LEVEL
light on the instrument
panel comes on, it means
you need to check your
engine oil level right away.
For more information, see ªCheck Oil Level Lightº in
the Index. You should check your engine oil level
regularly; this is an added reminder.
It's a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
The engine oil dipstick is
right behind the engine fans
and in front of the engine
oil fill cap. The top of
the dipstick is a round,
yellow loop.
Turn off the engine and give the oil several minutes to
drain back into the oil pan. If you don't, the oil dipstick
might not show the actual level.

6-12 Checking Engine Oil
Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.
When to Add Engine Oil
If the oil is at or below the ADD mark, then you'll need
to add at least one quart of oil. But you must use the
right kind. This part explains what kind of oil to use.
For crankcase capacity, see ªCapacities and
Specificationsº in the Index.
NOTICE:
Don't add too much oil. If your engine has so
much oil that the oil level gets above the
cross
-hatched area that shows the proper
operating range, your engine could be damaged.
The engine oil fill cap is behind the engine oil dipstick
and engine fans.
Be sure to fill it enough to put the level somewhere in
the proper operating range. Push the dipstick all the way
back in when you're through.
