Oil Pressure Gage (omrorv)
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.

Air Conditioning System
(OPTION)
The air conditioner and heater work
best if you keep your windows closed
while using them. Your vehicle also has
the flow-through ventilation system
described later
in this section.
3f : The left control knob sets the
fan speed. To select the force
of air you
want,
turn the knob. The fan is always
running unless the mode control is
moved to
OFF.
Temperature Control: The center
control knob regulates the temperature
of the air coming through the system.
Mode Control: The right control knob
changes the functions
of your system.
Air Conditioning
Your system has three air conditioner
settings. Before using your air
conditioner on very hot days, open the
windows long enough
to let hot inside
air escape. This reduces the amount
of
work your air conditioner's compressor
will have to do, which should help fuel
economy.
MAX: Use for maximum cooling. This
setting recirculates much
of the air
inside your vehicle
so it maximizes your
air conditioner's performance and your
vehicle's fuel economy.
A/C: Use for normal cooling on hot
days. This setting cools outside air and
directs it through the instrument panel
outlets.

Air Conditionina (CONI) -.
qg (Bi-Level): Use on cool, but
sunny days. This setting brings in the
outside air, but directs it in two ways.
The cool air is directed to the upper
portion of your body through the
instrument panel outlets, but slightly
warmer air is directed through the
heater ducts and defroster vents. At
times this temperature difference may be
more apparent than others.
The air conditioner compressor operates
in all three air conditioning positions. It
also operates in (Defrost) when
the outside temperature is higher than
about
40°F (4.5"C).
Ventilation
Use when outside temperatures are
mild, and little heating or cooling is
needed. Turn the right control knob to
2 (Vent). Air flow is directed
through the instrument panel outlets. Set
the center control knob to the
temperature desired.
Heating
Turning the right control knob to
72 (Heater) and the center control
knob clockwise will send heated air
through the heater ducts, and some
through the defroster vents.
3 (Vent) and (Heater) are
economical positions because the air
conditioner compressor doesn't run in
these two settings. This reduces engine
load, resulting in improved fuel
economy. If either setting fails to keep you
comfortable, or causes your windows
to fog up, turn the right control knob to
one of the air conditioning positions, or
to
(j@ (Defrost).
If you have the optional engine block
heater and use it during cold weather,
0°F (-18°C) or lower, your heating
system will more quickly provide heat
because the engine coolant is already
warmed. See the
Index under Engine
Block Heater.

and the windshield defroster vents.

The (@ (Defrost) setting directs most
air through the defroster vents, and
some through the heater ducts.

Defogging Windows with
Air Conditioning System
To defog the windshield, turn all three
control knobs to the far right. To defog
the side windows, turn the
right control knob to 12 (Bi-Level)
and the fan control knob to
HIGH. Aim
the side vents toward the side windows.
For increased air flow to the side vents,
close the center vents.
Rear Window Defogger (OPTION)
The rear window defogger uses a
warming grid to remove fog from the
rear window. Press
the defogger switch.
The indicator light will glow.
If your
vehicle is traveling under
45 mph
(70 kmlh), the rear window defogger
will turn off automatically after about
10 minutes of use. If your vehicle is
traveling over
45 mph (70 km/h), the
defogger will operate continuously. You
can
turn the defogger off by turning off
the ignition or pressing the switch again.
Do not attach a temporary vehicle
license across the defogger grid
on the
rear window.

Don’t use a razor blade or something
else
sharp on the inside of the rear
window. If you do,
you could cut
or damage the warming grid, and
the repairs wouldn’t be covered by
your warranty Your Pontiac’s
flow-through ventilation
system supplies outside air into the
vehicle when it is moving. Outside air
will also enter the vehicle when the
heater or the air conditioning fan is
running.
Ventilation Tips
Keep the hood and front air inlet free
of ice, snow, or any other obstruction
(such as leaves). The heater and
defroster will work far better, reducing the chance of fogging the inside of
your windows.
When you enter a vehicle in cold
weather,
turn the fan control knob to
HIGH for a few moments before
driving off. This helps clear the intake
ducts of snow and moisture, and
reduces the chance of fogging the
inside of your windows.
clear of objects. This helps air to
circulate throughout your vehicle.

Some driving conditions or climates
may cause a brake squeal when the
brakes are fmt applied or lightly
applied. This does not mean something
is wrong with your brakes.
Rear Drum Brakes
Your rear drum brakes don't have wear
indicators, but if you ever hear a rear
brake rubbing noise, have the rear brake
linings inspected. When you have the
front brakes replaced, have the rear
brakes inspected, too.
Brake linings should always be replaced
as complete axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does
not return to normal height, or if there
is a rapid increase in pedal travel. This
could be
a sign of brake trouble.

Problems on the Road
Engine Overheating (CONT)
If No Steam is Coming from Your
Engine:
If you get the overheat warning but see
or hear no steam, the problem may not
be
too serious. Sometimes the engine
can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high speed driving.
Idle for long periods in traffic.
Tow a trailer.
180
If you get the overheat warning with no
sign of steam, try this for a minute or so:
1 . If you have an air conditioner, turn it
off.
2. Turn your heater to full hot at the
highest fan speed and open the window as necessary.
3. Try to keep your engine under load
(in a drive gear where the engine
runs slower).
If you no longer have the overheat
warning,
you can drive. Just to be safe,
drive slower for about ten minutes.
If
the warning doesn’t come back on, you
can drive normally.
If the warning continues, pull over, stop,
and park your vehicle right away. If there’s
still no sign of steam, you can
idle the engine for two or three minutes
while you’re parked, to
see if the
warning stops.
But then, if you still have the warning,
TURN
OFF THE ENGINE AND GET
EVERYONE OUT
OF THE VEHICLE
until it cools down.
You may decide not to lift the hood but
to get service help right away.

Wheel Alignment and
Tire Balance
The wheels on your vehicle were
aligned and balanced carefully at
the
factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to have
your wheels aligned again. However, if
you notice unusual tire wear or your
vehicle pulling one way or the other, the
alignment may need to be reset. If you
notice your vehicle vibrating when
driving on a smooth road, your wheels
may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked
or badly rusted. If wheel nuts keep
coming loose, the wheel, wheel bolts,
and wheel nuts should be replaced. If
the wheel leaks air out, replace it
(except some aluminum wheels, which
can sometimes be repaired).
See your
Pontiac dealer if any of these conditions
exist.
Your dealer will know the kind of wheel
you need.
Each new wheel should have the same
load carrying capacity, diameter, width,
offset, and be mounted the same way as
the one it replaces.
If you need to replace any of your
wheels, wheel bolts, or wheel nuts,
replace them
only with new GM
original equipment parts. This way, you
will be sure
to have the right wheel,
wheel bolts, and wheel nuts for your
Pontiac model.
CAUTION I
Using the wrong replacement
I. wheels, wheel bolts, or wheel
nuts
on your vehicle can'be
dangerous.
It could affect the
braking and handling
of your
vehicle, make your tires lose air
and make you lose control. You
could have a collision in which you
or others could be injured. Always
use the correct wheel, wheel bolts,
and wheel nuts for replacement.

Finish Damage
Any stone chips, fractures or deep
scratches in the finish should be
repaired right away. Bare metal will
corrode quickly and may develop into a
major repair expense,
Minor chips and scratches can be
repaired with touch-up materials
available from your dealer or other
service outlets. Larger areas of finish
darnage can be corrected
in your
dealer’s body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow
removal and dust control can collect on
the underbody. If these are not removed,
accelerated corrosion (rust) can occur
on the underbody parts such as fuel
lines, frame, floor pan, and exhaust system even though they have corrosion
protection.
At least every spring, flush these
materials from the underbody with plain
water. Clean any areas where mud and other debris can collect. Dirt packed in
closed areas of the frame should be
loosened before being flushed. Your
dealer or
an underbody vehicle washing
system can do this for you.
Chemical Paint Spotting
Some weather and atmospheric
conditions can create a chemical fallout.
Airborne pollutants can fall upon and
attack painted surfaces on your vehicle.
This damage can take two forms:
blotchy, ringlet-shaped discolorations,
and small irregular dark spots etched into the paint surfhce.
Although no defect in the paint job
causes this, Pontiac will repair, at no
charge to the owner, the surfaces of new
vehicles damaged
by this fallout
condition within
l2 months or l2,OOO
miles (20 OOO km) of purchase,
whichever comes first.
