Oil Pressure Light
. .
If you have a problem with
your oil, this light may stay
on
after you start your
engine, or come on when
you are driving. This
indicates that oil is not
going through your engine
quickly enough to keep it
lubricated.
The engine could be low
on oil, or
could have some
other oil problem. Have it fixed right away.
The oil light could also come on in the following
situations:
When the ignition is on but the engine is not running,
the light will come on as a test to show you
it is
working, but the light will go out when you turn the
ignition to START. If it doesn't come on with the
ignition on, you may
have a
problem with the fuse or
bulb. Have
it
fixed right away.

On four cylinder engines, when the engine
is
idling
at
a
stop, the light may blink on and off. In addition,
if you make a hard stop, the light may
come on for a
moment. This is normal.
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.
