Oil Pressure Light
For vehicles with an oil
pressure light, if there
is a problem with the oil,
the light may stay on
after the engine is started,
or comes on while
driving.
This light indicates that oil is not going through the
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:
•
The light comes on briefly when the ignition is
turned on to show that it is working properly.
If it does not come on with the ignition on, there
may be a problem with the fuse or bulb. Have
it fixed right away.
•
Sometimes when the engine is idling at a stop, a
chime sounds and the light may blink on and off.
This is normal.
{
CAUTION:
Do not keep driving if the oil pressure is low.
The engine can become so hot that it catches fire.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice: Lack of proper engine oil maintenance
can damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.
