Oil Pressure Gage
( o m r o r v )
The oil pressure gage shows the engine
oil pressure in psi (pounds per square
inch) when the engine is running.
Canadian vehicles indicate pressure in
kPa. Oil pressure may vary with engine
speed, outside temperature and oil
viscosity, but readings above the red
warning zone indicate the normal
operating range.
A reading in the red zone may be caused
by a dangerously low oil level or other
problem causing low oil pressure. Have
your vehicle serviced immediately.
A
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.
Charging System Light
The charging system light will come on
briefly when you turn on the ignition,
but the engine is not running, as a check
to show you it is working. Then it
should go out. If it stays on when your
engine is running, or comes on while
you are driving, you may have a
problem with the electrical charging
system. It could indicate that you have a
loose generator drive belt or another
electrical problem. Have it checked
right away. Driving while this light is on
could drain your battery.
If you must drive a short distance with
the light on, be certain to turn off all
your accessories, such as the radio and
air conditioner.
