A CAUTION: ..
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside.
CO could overcome you and kill
you. You can’t see
it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that
is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn’t collect there.
Open
a window just a little on the side of the
vehicle
that’s away from the wind. This will help
keep
CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make
it go a little faster
than just idle. That
is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well-charged battery to
restart the vehicle, and possibly for signaling later
on
with your headlamps. Let the heater run for awhile.
Then, shut the engine
off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do
it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or so until help comes.

Towing a Trailer
If you don’t use the correct equipment and drive
properly, you can lose control when you pull a
trailer. For example, if the trailer
is too heavy, the
brakes may not work well
-- or even at all. You
and your passengers could be seriously injured.
Pull
a trailer only if you have followed all the
steps in this section.
Ask your Pontiac dealer for
advice and information about towing
a trailer
with your vehicle.
NOTICE:
Pulling a trailer improperly can damage your
vehicle and result in costly repairs not covered by
your warranty.
To pull a trailer correctly, follow
the advice in this part, and see your Pontiac
dealer
for important information about towing a
trailer with your vehicle.
Your vehicle can tow a trailer if it is equipped with the
3800 and 5.7L engines and proper trailer towing
equipment.
To identify what the vehicle trailering capacity
is for your vehicle,
you should read the inforrnation in
“Weight of the Trailer” that appears later in
this section.
But trailering is different than just driving your vehicle by
itself. Trailering means changes in handling, durability and
fuel economy. Successful, safe trailering
takes correct
equipment, and it has to be used properly.
That’s the reason for this part. In it are many
time-tested, important trailering tips and safety rules.
Many of these are important for your safety and
that of
your passengers. So please read this section carefully
before
you pull a trailer.
4-32

Load-pulling components such as the engine,
transmission, rear axle, wheel assemblies and tires
are
forced to work harder against the drag of the added
weight. The engine is required to operate at relatively
higher speeds and under greater loads, generating extra
heat. What’s more, the trailer adds considerably to wind
resistance, increasing the pulling requirements.
If You Do Decide To Pull A Trailer
If you do, here are some important points:

There are many different laws, including speed limit
restrictions, having to do with trailering. Make sure
your rig will be legal, not only where you live but
also where you’ll be driving.
A good source for this
information can
be state or provincial police.
Consider using a sway
control. You can ask a hitch
dealer about sway controls.
Don’t tow a trailer at all during the first
1,000 miles
(1 600 km) your new vehicle is driven. Your engine,
axle or other parts could be damaged.
Then, during the first 500 miles
(800 km) that you
tow a trailer, don’t drive over
50 mph (80 km/h) and
don’t make starts at full throttle. This helps your
engine and other parts
of your vehicle wear in at the
heavier loads.
0 Obey speed limit restrictions when towing a trailer,
Don’t drive faster than the maximum posted speed
for trailers (or no more than 55 mph (90 km/h)) to
save wear on your vehicle’s parts.
Three important considerations have to do with weight:
0 the weight of the trailer,
0 the weight of the trailer tongue
and the total weight on your vehicle’s tires.
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more
than 1,500 pounds (680 kg)
under normal driving conditions.
It should never weigh
more than 1,000 lbs. (450 kg) when driven on long
grades at high ambient temperatures. Above
90” F
(32°C). But even that can be too heavy.
It depends on how you plan to use your rig. For
example, speed, altitude, road grades, outside
temperature and how much your vehicle is used to pull a
trailer are all important. And,
it can also depend on any
special equipment that you have on your vehicle.
4-33

Driving On Grades Making Turns
I 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.
Turn Signals When Towing a nailer
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. 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
(3) instead of AUTOMATIC OVERDRIVE (a)
(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, it’s better not to
use FIFTH
(5) or SIXTH (6) gear. Just drive in
FOURTH
(4) (drive in FIFTH (5) if you have a
six-speed manual transmission) 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 transmiss’ion.
2. Have someone place chocks under the trailer wheels.
3, When the wheel C~OGBS 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 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:
Start your engine;
Shift into a gear; and
Release the parking brake.
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, 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 these
sections before
you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.

1.. Check the other vehicle. It must have a 12-volt
~~
battery with a negative ground system.
NOTICE:
If you leave your radio on, it could be badly
~~~ damaged. The repairs wouldn’t be covered by
your warranty.
If the other system isn’t a 12-volt system with a
negative ground, both vehicles can be damaged.
4. Open the hoods and locate the batteries.
2. Get the vehicles close enough so the jumper cables
can reach, but be
sure the vehicles aren’t touching
each oth’er.
If they are, it could cause a ground
connection
you don’t want. You wouldn’t be able to
start your Pontiac, and the bad grounding could
damage the electrical systems.
unnecessary accessories plugged into
the cigarette
lighter. Turn
off all lamps that aren’t needed as well
as radios.
This will avoid sparks and help save both
batteries.
In addition, it could save your radio!
3. Turn off the ignition on both vehicles. Unplug

An electric fan can start up even WLA the engine
is not running and can injure you. Keep hands,
clothing
and tools away from any underhood
electric fan.
5. Find the positive (+) and negative (-) terminals on
each battery.

Using a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded. Use a flashlight
if
you need more light.
Be sure the battery has enough water. You don’t
need to add water
to the Delco Freedom’ battery
installed in every new
GM vehicle. But if a
battery has filler caps, be sure the right amount
of fluid is there. If it is low, add water to take care
of that first. If you don’t, explosive gas could
be present.
Battery fluid contains acid that can burn you.
Don’t get it on you.
If you accidentally get it in
your eyes
or on your skin, flush the place with
water
and get medical help immediately. *
6. Check that the jumper cables don’t have loose or
missing insulation. If they
do, you could get a shock.
The vehicles could be damaged, too.
Before
you connect the cables, here are some basic
things
you should know. Positive (+) will go to
positive
(+) and negative (-) will go to negative (-)
or a metal engine part. Don’t connect positive (+) to
negative (-) or you’ll get a short that would damage
the battery and maybe other parts,
too.
1 A CAUTION:
I
Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engines are running.

9. Now connect the black negative (-) cable to the good
battery’s negative
(-) terminal.
Don’t let the other end touch anything until the next
step. The other end of the negative (-) cable doesn’t
go to the dead battery. It goes to a heavy unpainted
metal part
on the engine of the vehicle with the
dead battery.
10. Attach the cable at least 18 inches (45 cm) away
from the dead battery, but not near engine parts that
move. The electrical connection is just as good
there, but the chance
of sparks getting back to the
battery is much less.
the engine for a while.
11. Now start the vehicle with the good battery and run

12. Try to start the vehicle with the dead battery.
If it won’t start after a few tries, it probably
needs service.
13. Remove the cables in reverse order to prevent
electrical shorting. Take care that they don’t touch
each other
or any other metal.

Towing Your Vehicle
Try to have a GM dealer or a professional towing
service tow your Pontiac.
If your vehicle has been changed or modified since it
was factory-new by adding aftermarket items like fog
lamps, aero skirting, or special tires and wheels, these
instructions may not be correct.
Before you
do anything, turn on the hazard
warning flashers.
When
you call, tell the towing service:
0 That your vehicle cannot be towed from the front or
rear with sling-type equipment.
0 That your vehicle has rear-wheel drive.
The make, model and year of your vehicle.
0 Whether you can still move the shift lever.
If there was an ac’cident, what was damaged.
When the towing service arrives, let the tow operator
know that this manual contains detailed towing
instructions and illustrations. The operator
may want to
see them.
