Check Oil Light
This light will come on briefly when you start
your vehicle.
If the light stays on after starting your vehicle,
or comes on and chimes while you are driving, 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 "Engine Oil" in the Index.
A false CHECK OIL light may be generated when
parking on steep grades.

You will have a CHECK
OIL light in your
instrument panel cluster.
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.
