Engine Oil Pressure Warning
Light
This light should come on briefly
as you start the engine, as a check
to show you it is working properly.
If it doesn't come on, then have it
fixed so it will be ready to warn
you if there is a problem.
If you have a problem with the oil,
this light may stay on after you
start the engine, or come on while
you are driving. This indicates that
oil is not going through the engine
quickly enough to keep it lubricat-
ed. The engine could be low on
oil, or could have some other oil
problem. Have it fixed right away.
Section 1
CAUTION
Do not keep driving with low oil
pressure. Your engine could
overheat and may catch on fire.
You or others could be burnt.
Check the oil as soon as possi-
ble and have your vehicle
serviced.
NOTICE
Engine damage due to neglect-
ed oil problems can be costly to
repair and is not covered by
your warranty.
