Forward Gears (Three Speed)
DRIVE (D): This position is for normal driving with the
three speed automatic transaxle.
SECOND (2): This position gives you more power but
lower
fuel economy. You can use SECOND (2) on hills.
It
can help control your speed as you go down steep
mountain roads, but then you would
also want to use
your brakes off and on.
NOTICE:
Don’t drive in SECOND (2) for more than 5 miles
(8 km), or at speeds over 55 mph (88 km/h), or
you can damage your transaxle. Use DRIVE
@)
as much as possible.
Don’t shift into
SECOND (2) unless you are going
slower than
65 mph (105 M), or you can
damage your engine.
FIRST (1): This position gives you even more power
(but lower fuel economy) than
SECOND (2). You can
use it on very steep hills, or in deep snow or mud.
If the
shift lever
is put in FIRST (l), the transaxle won’t shift
into first gear until the vehicle
is going slowly enough.
NOTICE:
If your front wheels can’t rotate, don’t try to
drive. This might happen
if you were stuck in
very deep sand
or mud or were up against a solid
object. You could damage your transaxle.
Also, if you stop when going uphill, don’t hold
your vehicle there with only the accelerator
pedal. This could overheat and damage the
transaxle. Use your brakes to hold your vehicle in
position on
a hill.

If the anti-lock brake system warning light stays on
longer than normal after you’ve started your engine, turn
the ignition off. Or, if the light comes on
and stays on
when you’re driving, stop as soon as possible and turn
the ignition
off. Then start the engine again to reset the
system. If the light still stays on, or comes on again
while you’re driving, your Pontiac needs service.
If the
light
is on but not flashing and the regular brake system
warning light isn’t on, you still have brakes, but you
don’t have anti-lock brakes.
. Engine Coolant Temperature Warning
Light
This light tells you that your
engine coolant has
overheated or your radiator
cooling fan is not working.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop
your vehicle and turn the engine
off as soon as possible.
HOT COOLANT CAN BURN YOU BADLY!
In “Problems on the Road”, this manual shows what to
do. See “Engine Overheating” in the Index.

Engine Coolant Temperature Gage
loo b
280
-E- -
r-r .J
This gage shows the engine coolant temperature. If the
gage pointer moves into the red area, your engine
is too
hot!
That reading means the same thing as the warning light.
It means that your engine coolant has overheated.
If you have been operating your vehicle under normal
driving conditions, you should pull
off the road, stop
your vehicle and
turn off the engine as soon as possible.
HOT COOLANT CAN BURN YOU BADLY!
In “Problems on the Road”, this manual shows what to
do. See “Engine Overheating’, in the Index.
Low Coolant Warning Light
LOW
COOLANT
If this light comes on and
stays on, the vehicle should
be promptly pulled off the
road
and the coolant level
checked. See “Engine
Coolant” in the Index.
If
there are visible signs of
steam see “Engine
Overheating” in the:Index
before opening the hood.

When towing a trailer, the green arrows on your
instrument panel will flash for turns even
if the bulbs on
the trailer
are burned out. Thus, you may think drivers
behind you are seeing your signal when they
are not. It’s
important to check occasionally to be sure the trailer
bulbs
are still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don’t shift
down, you might have to use your brakes
so much that
they would get hot and no longer work well.
On a long uphill grade, use the highest gear possible. If
you cannot maintain posted speeds, driving at a lower
speed may help avoid overheating your engine and
transaxle.
If you have a manual transaxle with fifth gear, it’s better
not
to use fifth gear. Just drive in fourth gear (or, as you
need to, a lower gear).
Parking on Hills
You really should not park your vehicle, with a trailer
attached, on a
hill. If something goes wrong, your rig
could
start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But if you ever have to park your rig on a hill, here’s
how to do it:
1. Apply your regular brakes, but don’t shift into
PARK (P) yet, or into gear for a manual transaxle.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking
brake, and then shift to PARK (P), or REVERSE (R)
for a manual transaxle.
5. Release the regular brakes.

NOTICE:
Towing a vehicle over rough surfaces could
damage a vehicle. Damage can occur from vehicle
to ground or vehicle to wheel-lift equipment. To
help avoid damage, install a towing dolly and
raise the vehicle until adequate clearance is
obtained between the ground and/or wheel-lift
equipment.
Do not attach winch cables or J-hooks to
suspension components when using car carrier
equipment.
Always use T-hooks inserted in the
T-hook Slots.
Attach a separate safety
chain to each side of the
axle inboard
of the spring.
Engine Overheating
You will find a coolant temperature gage or the warning
light about
a hot engine on your Pontiac’s instrument
panel. See “Coolant Temperature Gage” and “Coolant
Temperature Warning Light” in the Index. You will also
find a low coolant warning light on your Pontiac’s
instrument panel.

If Steam Is Coming From Your Engine
NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered by your warranty.
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.
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 on your heater to full hot at the highest fan
3. If you’re in a traffic jam, shift to NEUTRAL (N);
speed and open the window as necessary.
otherwise, shift to the highest gear while driving --
AUTOMATIC OVERDRIVE (GB) or DRIVE (D) for
automatic transaxles.

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 ofthe 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.
When you decide it’s safe to lift the hood, here’s what
you’ll see:
A. Coolant surge tank with pressure cap
B. Electric engine fan

ProCarManuals.com

Engine damage from running your engine
without coolant isn’t covered
by your warranty.
If there seems to be no leak, with the engine on check to
see if the electric engine fan is running.
If the engine is
overheating, the fan should be running. If it isn’t, your
vehicle needs service.
How to Add Coolant to the Coolant Surge
Tank
If you haven’t found a problem yet, but the coolant level
isn’t at or above FULL COLD, add a 50/50 mixture of
clean water (preferably distilled) and a proper antifreeze
at the coolant surge
tank, but be sure the cooling system,
including the coolant surge tank pressure cap, is cool
before you do it. (See “Engine Coolant” in the Index for
more information about the proper coolant
mix.)

Hydraulic Clutch Refer to the Maintenance Schedule to determine how often you should check the fluid level in your clutch
The hydraulic clutch linkage in your vehicle is master cylinder reservoir and for the proper fluid. See
self-adjusting. The clutch master cylinder reservoir is “Owner Checks and Services” and “Recommended
filled with hydraulic clutch fluid. Fluids and Lubricants” in the Index.
It isn’t a good idea to “top off’ your clutch fluid. Adding
fluid won’t correct a leak. How to Check
A fluid loss in this system could indicate a problem.
Have the system inspected and repaired.
When to Check and What to Use
The proper fluid should be added if the level is at or
below the STEP mark on the reservoir cap. See the
instructions on the reservoir cap.
Engine Coolant
The following explains your cooling system and how to
add coolant when it is low. If you have a problem with
engine overheating, see “Engine Overheating” in the
Index.
The proper coolant for your Pontiac will:
0 Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 262 OF ( 128 O C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
Let the warning lights work as they should.
