Oil Pressure Indicator (OPTION)
This indicator tells you if there could be
a problem with your engine oil pressure.
The pointer should be above the red
zone when the engine is running.
I CAUTION
Readings in the red area tell you that
the engine is low on oil, or that you
might have some other oil problem. See
the
Index under Engine Oil.
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.
Battery Warning Light
The charging system light will come on
briefly when you turn on the ignition
as
a check to show you it is working. Then
it should go out.
If it stays on, 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.

Voltmeter (OPTION)
When the engine is running, the gage
shows the condition
of the charging
system. Readings between the red
warning zones indicate the normal
operating range.
Readings in either red warning zone
indicate a possible problem in the
electrical system. Have your vehicle
serviced immediately.
When your engine
is not running, but
the ignition is
on (in the Run position),
the gage shows your battery’s state
of
charge.
Brake System Warning Light
Your Pontiac’s hydraulic brake system
is divided into two parts. If one part
isn’t working, the other part can still
work and stop you. For good bralung,
though, you need both parts working
well.
If the warning light goes on, there
could be a brake problem.
Have your brake system inspected right
away.
This light should come on as you start
the vehicle.
If it doesn’t come on then,
have it fixed
so it will be ready to warn
you
if there’s a problem.
This light will also come on when you
set your
parking brake, and will stay on
if your parking brake doesn’t release fully.
If it stays on after your parking
brake is fully released, it means you
have a brake problem.
If the light comes on while driving, pull
off the road and stop carefully. You maJ
notice that the pedal is harder to push.
Or, the pedal may
go closer to the floor.
It may take longer to stop.
If the light is
still on, have the vehicle towed for
service. (See the
Index under Towing
Your Pontiac.)
1 CAUTION
Your brake system may not
be working properly if the .
WIMC warning light is on. Driving
with the brake warning light ora can
lead to an accident. If the light is
still on after you’ve pulled off the
road and stopped carefully, have
I the vehicle towed €or senrice.

Anti-Lock Brake System Warning
Light (OPTION)
With anti-lock, this light will go on
when you start your engine and it will
stay on for three seconds. That’s
normal.
If the light doesn’t come on,
have it fixed
so it will be ready to warn
you if there is a problem.
If the light stays on or comes on when
you’re driving,
stop as soon as possible
and turn the key off. Then start the
engine to reset the system. If the light
still stays
on, or comes on again while
you’re driving, your Pontiac needs
service. Unless the regular brake system
warning light
is also on, you will still
have brakes, but not anti-lock brakes.
If
the regular brake system warning light
is also on, see the Index under Brake
System Warning Light.
If the anti-lock brake system warning
light ever flashes, your anti-lock brake
system is still working but needs service
as soon as possible.

Care of Your Cassette Tape
Player
(CONT.)
Clean your tape player with a wiping-
action, non-abrasive cleaning cassette,
and follow the directions provided with
it.
Cassettes are subject to wear and the
sound quality may degrade over time.
Always make sure that the cassette tape
is
in good condition before you have
your tape player serviced.
Care of Your Compact Discs
Handle discs carefully. Store them in
their original cases or other protective
cases and away from direct sunlight and
dust. If the surface of a disc is soiled,
dampen a clean, soft cloth in a mild,
neutral detergent solution and clean it,
wiping from the center to the edge.
Be sure never to touch the signal
surface when handling discs. Pick up
discs by grasping the outer edges or the
edge of the hole and the outer edge.
Fixed Mast Antenna
The fixed mast antenna can withstand
most car washes without being
damaged.
If the mast should ever
become slightly bent,
you can straighten
it
out by hand. If the mast is badly bent,
as it might be by vandals, you should
replace it.
Check every once in a while to be sure
the mast is still tightened to the fender.
