Engine Coolant Heater
(Canada Only)
In very cold weather, 0 OF (- 1 8 O C) or colder, the engine
coolant heater can help. You’ll get easier starting
and
better fuel economy during engine warm-up. Usually,
the coolant heater should be plugged in a minimum of
four hours prior to starting your vehicle.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is attached to the outside
of the underhood
fuse
box.
3. Plug it into a normal, grounded 110-volt AC outlet.
A CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind
of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into
a properly grounded three-prong
110-volt AC outlet.
If the cord won’t reach, use a
heavy-duty three-prong extension cord rated for
at least 15 amps.

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
25 miles (40 km), or at speeds over 55 mph
(88 km/h), or you can damage your transmission.
Use AUTOMATIC OVERDRIVE
(a) or
THIRD (3) as much as possible.
Don’t shift into
SECOND (2) unless you are going
slower than
65 mph (105 kmh), or you can
damage your engine. FIRST
(1): This
position (if equipped) 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 gear shift lever is put in first
gear, the transmission won’t shift into
FIRST (1) until
the vehicle is going slowly enough.
NOTICE:
If your rear 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 transmission.
Also, if you stop when going uphill, don’t hold
your vehicle there with only the accelerator
pedal. This could overheat and damage the
transmission. Use your brakes or shift into
PARK (P) to hold your vehicle in position
on a hill.
Maximum engine speed is limited to protect driveline
components
from improper operation.

Leaving Your Vehicle With the Engine
Running (Automatic Transmission
Only)
It can be dangerous to leave your vehicle with the
engine running. Your vehicle could move
suddenly if the shift lever
is not fully in PARK (P)
with the parking brake firmly set. And, if you
leave the vehicle with the engine running, it could
overheat and even
catch fire. You or others could
be injured. Don’t leave your vehicle with the
engine running unless you have to.
Torque Lock (Automatic Transmission)
If you are parking on a hill and you don’t shift your
transmission into
PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl in
the transmission. You may find
it difficult to pull the
shift lever out
of PARK (P). This is called “torque lock.”
To prevent torque lock, set the parking brake and then
shift into
PARK (P) properly before you leave the
driver’s seat.
To find out how, see “Shifting Into
PARK (P)” in the Index.
When you are ready
to drive, move the shift lever out of
PARK (P) before you release the parking brake.
If torque lock does occur, you may need to have another
vehicle push
yours a little uphill to take some of the
pressure from the parking pawl
in the transmission, so
you can pull the shift lever out of PARK (P).

Low Traction Light
LOW
TRAC
When your anti-lock system
is adjusting brake pressure
to help avoid
a braking skid,
this light will come on.
If you have the traction control system, this light will
also come on when the system is limiting wheel spin.
You may feel or hear the system working, but this is
normal. Slippery road conditions may exist if the low
traction light
comes on, so adjust your driving
accordingly. The light will stay on for a few seconds
after the traction control system stops limiting
wheel spin.
The low traction light
also comes on briefly when you
turn the ignition key to
RUN. If the light doesn’t come
on then, have it fixed so it will be there to tell you when
the anti-lock
brake system or traction control system
is active.
Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature.
If the
gage pointer moves into
the red area,
your engine
is too hot! 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.
In “Problems on the Road,” this manual shows what to
do. See “Engine Overheating” in the Index.

Low Coolant Light (5.7L V8 Engine)
This warning light should
come on while you are
starting your engine.
If the
light doesn’t come on, have
it repaired.
~
Your vehicle is equipped with a low coolant indicator
which is designed to detect when the coolant level drops
below set limits.
If the low coolant level sensor (on the
radiator) drops while the engine is running, the low
coolant indicator will light and remain lit until the
ignition
is turned to OFF. Check coolant level and add
coolant as needed. The low coolant light might stay on
after filling the radiator. Turn the ignition to
OFF, then
restart
the engine to verify that the low coolant light
goes out. See “Engine Coolant” in the Index.
NOTICE:
Driving with the low coolant light on could cause
your vehicle to overheat. See “Engine Overheating”
in the Index. Your vehicle could be damaged and it
wouldn’t be covered by your warranty.

Making &rns
NOTICE:
Making very sharp turns while trailering could
cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you’re turning with a trailer, make wider turns
than normal.
Do this so your trailer won’t strike
soft shoulders, curbs, road signs, trees or other
objects. Avoid jerky or sudden maneuvers. Signal
well in advance.
lbrn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal flasher and/or extra wiring. Check
with your Pontiac dealer. The green arrows on your
instrument panel will flash whenever
you signal a turn
or lane change. Properly hooked up, the trailer lamps
will also flash, telling other drivers you’re about to turn,\
change lanes
or stop. 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, shift down and reduce your speed to around
45 mph (70 km/h) to reduce the
possibility of engine and transmission overheating.
If you are towing a trailer and you have an automatic
transmission with overdrive, you may prefer to drive in
THIRD
(D) instead of AUTOMATIC OVERDRIVE @
(or, as you need to, a lower gear). Or, if you have a
manual transmission with FIFTH
(5) (or SIXTH (6) )
gear and you are towing a trailer. Just drive in
FOURTH
(4) gear (or drive in FIFTH (5) if you have a
six-speed manual transmission) or, as
you need
to, a lower gear.

0 Shift into a gear; and
0 Release the parking brake.
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 transmission.
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) for an
automatic transmission, or
REVERSE (R) for a
manual transmission.
5. Release the regular brakes.
When You Are Ready to Leave After
Parking on
a Hill
1. Apply your regular brakes and hold the pedal down
while
you:
0 Start your engine;
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on
this. Things that are especially important in trailer
operation
are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, drive belts, cooling
system and brake adjustment. Each of these is covered
in
this manual, and the Index will help you find them
quickly. If you’re trailering, it’s a good idea to review
this information before you start your trip.
Check periodically to
see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See “Engine Overheating”
in the Index.

Engine Overheating
You will find a coolant temperature gage on your
vehicle’s instrument panel. You may also
find a low
coolant warning light on your vehicle’s instrument panel
(5.7L V8 engine only).
If Steam Is Coming From Your Engine
I
Steam from an overheated engine can burn you
badly, even
if you just open the hood. Stay away
from the engine if you see or hear steam coming
from it. Just turn it
off and get everyone away
from the vehicle until it cools down. Wait until
there
is no sign of steam or coolant before you
open the hood.
If you keep driving when your engine
is
overheated, the liquids in it can catch fire.
You or others could be badly burned. Stop
your engine if it overheats, and get out of the
vehicle until the engine is cool.
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.
