2007 PONTIAC GRAND PRIX service schedule

Oil Pressure Light
If there is a problem
with the vehicle’s oil
pressure, this light may
stay on when the
engine is started.
It may also come on while the vehicle is being
driven. This indicates that the engine could be low
on oil or could have some other oil problem.
Have it xed right away.
The oil light could also come on in two other
situations:
When the ignition is on but the engine is not
running, the light will come on as a test to
indicate it is working. The light will go out when
the ignition is turned to RUN. If it does not come
on while the ignition is in the on position, there
may be a problem with the fuse or bulb. See
Fuses and Circuit Breakers on page 460.
If the brakes are applied quickly and the vehicle
makes a hard stop, the light may come on for a
moment. This is normal.
{CAUTION:
Do not keep driving if the oil pressure is
low. If you do, your engine can become so
hot that it catches re. You or others
could be burned. Check your oil as soon
as possible and have your vehicle
serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would
not be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.
