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 Light
This light will come on
briefly when you start
your vehicle.
If the light comes on and you hear a chime or stays on
after starting your vehicle, your engine oil level should
be checked.
Prior to checking the oil level, be sure your vehicle has
been shut off for several minutes and is on a level
surface. Check the oil level on your dipstick and bring it
to the proper level. See ªEngine Oilº in the Index.
NOTE: A false CHECK OIL light may be generated
when parking on steep grades.
The oil level monitoring system only checks oil level
during the brief period between key on and engine
crank. It does not monitor engine oil level when the
engine is running. Additionally, an oil level check is
only performed if the engine has been turned off for a
considerable period of time allowing the oil normally in
circulation to drain back into the oil pan.

Engine Oil
If the CHECK OIL 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
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
yellow and located on the
front of the engine.
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.

6-13 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 line, 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 upper
mark that shows the proper operating range,
your engine could be damaged.
The engine oil fill cap is located on the front of the engine.
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.
