Parking on Hills (CONT.)
Parking Uphill
If there is a curb, turn your wheels to
the
left if the curb is at the right side of
your vehicle. If
you’re going uphill on
a one-way
street and you’re parking on the left
side, your wheels should point to the
right. If
there is no curb when you’re parking
uphill, turn the wheels to the right.
If there is no curb when you’re parking
uphill on the left side of a one-way
street, your wheels would be turned to
the left.

Torque Lock
If you are parking on a hill and you
don’t shift your transaxle into P (Park)
properly, the weight of the vehicle may
put too much force on the parking pawl
in the transaxle.
You may find it
difficult to pull the shift lever out of
P (Park). This is called “torque lock.”
To prevent torque lock, always be sure
to shift into
P (Park) properly before
you leave the driver’s seat. To find out
how, see the
lndex under Shifting Into
P (Park).
When you are ready to drive, move the
shift lever out
of P (Park) 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 transaxle,
so you can pull the
shift lever out
of P (Park).
Winter Driving
Here are some tips for winter driving:
Have your Pontiac in good shape for
winter. Be sure your engine coolant
mix is correct.
Snow tires can help in loose snow,
but they may give
you less traction on
ice than regular tires. If you do not
expect to be driving in deep snow, but
may have to travel over ice,
you may
not want to switch to snow tires at all.
.. “I
. ..
You may want to put winter
emergency supplies
in your trunk.
Include an ice scraper, a small brush
or broom, a supply of windshield
washer fluid, a rag,
some winter outer
clothing, a small shovel,
a flashlight, a
red cloth, and a couple of reflective
warning triangles.
And, if you will be
driving under severe conditions,
include
a small bag of sand, a piece of
old carpet or a couple of burlap bags
to help provide traction. Be sure you
properly secure these items in your
vehicle.

Drivjng on Snow or Ice
Most ‘of the time, those places where
your tires meet the road probably have
good traction.
However,
if there is snow or ice
betw,een your tires and the road, you
can have a very slippery situation.
You’ll have a lot less traction or “grip’’
an’d will need to be very careful.
What’s the worst time for this? “Wet
ice.” Very cold snow or ice can be slick
and hard to drive on. But wet ice can be
even more trouble because it may offer
the least traction of all. You can get
“wet ice” when it’s about freezing
(32”F, 0.C) and freezing rain begins to
fall. Try to avoid driving
on wet ice until
salt and sand crews can get there.
172
Whatever the condition-smooth ice,
packed, blowing or loose snow-drive
with caution. Accelerate gently. Try not
to break the fragile traction. If you
accelerate too fast, the drive wheels will
spin and polish the surface under the
tires even more.
Unless you have the anti-lock braking
system, you’ll want to brake very gently,
too.
(If you do have anti-lock, see the
Index under Anti-Lock Brake System.
This system improves your vehicle’s
ability to make a hard stop on a slippery
road.) Whether you have the anti-lock
braking system
or not, you’ll want to
begin stopping sooner than you would
on dry pavement. Without anti-lock
brakes, if you feel your vehicle begin to
slide, let
up on the brakes a little. Push
the brake pedal down steadily to get the
most traction you can. Remember, unless you have anti-lock,
if
you
brake so hard that your wheels stop
rolling, you’ll just slide. Brake
so your
wheels always keep rolling and you can still steer.
Whatever your braking system, allow greater following distance on any
slippery road.
Watch for slippery spots. The road might be fine until you hit a spot
that’s covered with ice. On an
otherwise clear road, ice patches may
appear in shaded areas where the sun
can’t reach: around clumps
of trees,
behind buildings, or under bridges.
Sometimes the surface
of a curve or
an overpass may remain icy when the
surrounding roads are clear. If you see
a patch of ice ahead
of you, brake
before you are on it. Try not to brake
while you’re actually
on the ice, and
avoid sudden steering maneuvers.

If You’re Caught in a Blizzard
If you are stopped by heavy snow, you
could be in a serious situation. You
should probably stay with your vehicle
unless you
how for sure that you are
near help and you can hike through the
snow. Here are some things
to do to
summon help and keep yourself and
your passengers safe:
Turn on your hazard warning flashers.
Tie a red cloth to your vehicle to alert
police that you’ve been stopped by the
snow.
* Put on extra clothing or wrap a
blanket
around you, If you have no
blankets or extra clothing, make body
insulators
from newspapers, burlap
bags, rags,
floor mats-anything you
can
wrap around yourself or tuck
under
your clothing to keep warm.
but be
careful.
You can run the engine to keep warm,
A 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 was 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.

Your Driving and the Road
If You’re Caught in a Blizzard
(COW.)
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 headlights. Let the
heater run for
a while.
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
CAUTlON
f
A
If you don’t use the correct
equipment and drive
properly, you can lose control whf
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.
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
section.
ProCarManuals.com

Do not tow a trailer if your vehicle is
equipped with a 3.4L (VIN Code X)
engine and a manual transaxle.
Your Pontiac can tow a trailer if it is
equipped with a
3.1L (VIN Code T)
engine or a 3.4L (VIN Code X) engine
and an automatic transaxle, and proper
trailer towing equipment.
To identify
what the vehicle trailering capacity is
for your vehicle, you should read the
information 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 section. 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. Load-pulling components such
as the engine, transaxle, 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.
All of that means changes in:
Handling
Durability
Fuel economy
If You Do Decide to Pull a Trailer
If you do, here are some important
points.
There are many different laws 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
control.
Don’t tow a trailer at all during the
first
500 miles (800 km) your new
vehicle is driven. Your engine, axle or
other parts could be damaged.
ProCarManuals.com

Your Driving and the Road
H You Do Decide to Pull a Trailer
(CONT.)
Then, during the first 500 miles
(800 krn) 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.
Three important considerations have
to do with weight:
Weight of the Trailer
How heavy can a trailer safely be? It
should never weigh more than
1,000
pounds (450 kg). 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.

dealer for our trailering information or
advice, or you can write

Weight of the Trailer Tongue
The tongue load (A) of any trailer is
an important weight to measure
because it affects the total capacity
weight of your vehicle. The capacity
weight includes the curb weight of the
vehicle, any cargo you may carry in it,
and the people who will be riding in
the vehicle. And if
you will tow a
trailer, you must subtract the tongue
load from your vehicle’s capacity
weight because your vehicle will be
carrying that weight, too.
See the
Index under Loading Your Vehicle for
more information about your vehicle’s
maximum load capacity. The
trailer tongue
(A) should weigh
10% of the total loaded trailer weight
(B). After you’ve loaded your trailer,
weigh the trailer and then the tongue,
separately, to see
if the weights are
proper. If they aren’t,
you may be able
to get them right simply by moving
some items around in the trailer.
Total Weight on Your Vehicle’s
Tires
Be sure your vehicle’s tires are inflated
to the limit for cold tires.
You will find
these numbers on the Certification
label at the rear edge
of the driver’s
door,
or see the Index under Tire
Loading.
Then be sure you don’t go
over the GVW limit for your vehicle.
Hitches
It’s important to have the correct hitch
equipment. Crosswinds, large trucks
going by, and rough roads are a few
reasons
why you’ll need the right hitch.
Here are some rules to
follow:
Will you have to make any holes in the
body of your vehicle
when you install
a trailer hitch? If you
do, then be sure
177
ProCarManuals.com

Your Driving and the Road
If You Do Decide to Pull a Trailer
(CONT.)
to seal the holes later when you
remove the hitch. If you don’t seal
them, deadly carbon monoxide
(CO)
from your exhaust can get into your
vehicle. (See the
Index under Carbon
Monoxide.) Dirt and water can, too.
4 The bumpers on your vehicle are not
intended for hitches.
Do not attach
rental hitches or other bumper-type
hitches to them. Use only a frame-
mounted hitch that does not attach to
the bumper.
Safety Chains
You should always attach chains
between your vehicle and your trailer.
Cross the safety chains under the
tongue of the trailer
so that the tongue
will not
drop to the road if it becomes
separated
from the hitch. Instructions
about safety chains may
be provided by
the hitch manufacturer
or by the trailer
manufacturer. Follow the
manufacturer’s recommendation for
attaching safety chains. Always leave
just enough slack
so you can turn with
your rig. And, never allow safety chains
to drag on the ground.
Trailer Brakes
Does your trailer have its own brakes?
Be sure to read and follow the
instructions for the trailer brakes
so
you’ll be able to install, adjust and
maintain them properly.
If your vehicle has anti-lock brakes,
do not try to tap into your vehicle’s
brake system.
If you do, both brake
systems won’t work well, or at all.
Even if your vehicle doesn’t have anti-
lock brakes, don’t tap into your
vehicle’s brake system
if the trailer’s
brake system will use more than
0.02
cubic inch (0.3 cc) of fluid from your
vehicle’s master cylinder. If it does,
both braking systems won’t work
well. You could even lose your brakes.
ProCarManuals.com

Will the trailer brake parts take 3,000
psi (20 650 1tPa) of pressure? If not,
the trailer brake system must not be
used with your vehicle.
If everything checks out this far, then
make the brake fluid tap at the upper
rear master cylinder port. But don’t
use copper tubing for this. If you do,
it will bend and finally break
off. Use
steel brake tubing.
Driving with a Trailer
Towing a trailer requires a certain
amount of experience. Before setting
out for the open road, you’ll want to get
to know your rig. Acquaint yourself
with the feel of handling and braking
with the added weight of the trailer.
And always keep in mind that the
vehicle you are driving is now a good
deal longer and not nearly
so responsive
as your vehicle is by itself.
Before you start, check the trailer hitch
and platform, safety chains, electrical
connector, lights, tires and mirror
adjustment. If the trailer has electric
brakes, start your vehicle and trailer
moving and then apply the trailer brake
controller by hand to be sure the brakes
are working. This lets
you check your
electrical connection at the same time.
During your trip, check occasionally to
be sure that the load is secure, and that
the lights and any trailer brakes are still
working.
Following Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving your vehicle without
a trailer.
This can help you avoid situations that
require heavy braking and sudden
turns.
Passing
You’ll need more passing distance up
ahead when you’re towing a trailer.
And, because you’re a
good deal longer,
you’ll need to
go much farther beyond
the passed vehicle before you can return
to your lane.
Backing Up
Hold the bottom of the steering wheel
with one hand. Then, to move
the
trailer to the left, just move that hand to
the left.
To move the trailer to the right,
move your hand to the right. Always
back up slowly and, if possible, have
someone guide you.
