2003 PONTIAC GRAND PRIX Owners Manual

Driving 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 between your tires and
the road, you can have a very slippery situation.
You’ll have a lot less traction or “grip” and will need to
be very careful.
I I
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; OOC) and freezing rain begins
to fall. Try to avoid driving on wet ice until salt and
sand crews can get there.
Whatever the condition
- smooth ice, packed, blowing
or loose snow
- drive with caution.
If you have traction control or enhanced traction, keep
the system on. It will improve your ability to accelerate
when driving
on a slippery road. Even though your
vehicle has a traction control system you’ll want to slow
down and adjust your driving to the road conditions.
See Traction Control System (TCS) on page
4- 10.
If you don’t have a traction control or enhanced traction
system, accelerate gently. Try not to break the gentle
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 Braking on
page 4-6. This system
improves your vehicle’s stability when you 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.
4-28

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.
0 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 know for sure that you are
near help and you can hike through the snow.
4-29

Here are some things to do to summon help and keep
yourself and your passengers safe:
Turn on your hazard 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.
You can run the engine to keep warm,
but be careful.

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. I
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 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.

If You Are Stuck: In Sand, Mud,
Ice or Snow
In order to free your vehicle when it is stuck, you will
need
to spin the wheels, but you don’t want to spin your
wheels too fast. The method known as “rocking” can
help you get out when you’re stuck, but you must
use caution.
If yo
et your tires s 1 ai -. spee--7 ~~~ -y can
explode, and you or others could be injured.
And, the transaxle or other parts of the vehicle
can overheat. That could cause an engine
compartment fire or other damage. When you’re
stuck, spin the wheels as little as possible. Don’t spin the wheels above
35 mph (55 km/h)
as shown on the speedometer.
Notice: Spinning your wheels can destroy parts of
your vehicle as well as the
tires. If you spin the
wheels too fast while shifting your transaxle back
and forth, you can destroy your transaxle. See
“Rocking Your Vehicle To Get
It Out.’’
For information about using tire chains on your vehicle,
see Tire Chains on page
5-75.
Rocking Your Vehicle To Get It Out
First, turn your steering wheel left and right. That will
clear the area around your front wheels.
If your vehicle
has traction control, you should turn the system
off.
See Traction Control System (TCS) on page 4-10. Then
shift back and forth between REVERSE (R) and a
forward gear, spinning the wheels as little as possible.
Release the accelerator pedal while you shift, and press
lightly on the accelerator pedal when the transaxl is in
gear. By slowly spinning your wheels in the forward and
reverse directions, you will cause a rocking motion
that may free your vehicle. If that doesn’t get you out
after
a few tries, you may need to be towed out. If you
do need
to be towed out, see “Towing Your Vehicle”
following.

Towing
Towing Your Vehicle
Consult your dealer or a professional towing service if
you need to have your disabled vehicle towed. See
Roadside Assistance Program
on page 7-5.
If you want to tow your vehicle behind another vehicle
for recreational purposes (such as behind a motorhome),
see “Recreational Vehicle Towing” following. With
the proper preparation and equipment, many
vehicles can be towed in these ways. See “Dinghy
Towing” and “Dolly Towing,” following.
Here are some important things to consider before you
do recreational vehicle towing:
Recreational Vehicle Towing
Recreational vehicle towing means towing your vehicle
behind another vehicle
- such as behind a motorhome.
The two most common types of recreational vehicle
towing are known as “dinghy towing” (towing your
vehicle with all four wheels on the ground) and
“dolly towing” (towing your vehicle with two wheels on
the ground and two wheels up on a device known
as a “dolly”). What’s
the towing capacity of the towing vehicle?
Be sure you read the tow vehicle manufacturer’s
recommendations.
How far will you tow? Some vehicles have
restrictions on how far and how long they can tow.
Do you have the proper towing equipment?
See your dealer or trailering professional for
additional advice and equipment recommendations. Is your vehicle ready to be towed? Just as you
would prepare your vehicle for a long trip, you’ll
want to make sure your vehicle
is prepared to be
towed. See Before Leaving on
a Long Trip on
page
4-24.

Dinghy Towing
Notice: Towing your vehicle with all four wheels on
the ground will damage drivetrain components.
Your vehicle was not designed to be towed with all four
wheels on the ground.
If your vehicle must be towed,
you should use a dolly. See “Dolly Towing” following for
more information.
Dolly Towing
Your vehicle can be towed using a dolly. To tow your
vehicle using a dolly, follow these steps:
1. Put the front wheels on the dolly.
2. Put the vehicle in PARK (P).
3. Set the parking brake and then remove the key.
4. Clamp the steering wheel in a straight-ahead
position.
5. Release the parking brake.

OT, ADD 28KPA(4PSI)
FOR MORE INFORMATION
Two labels on your vehicle show how much weight it
may properly carry. The Tire-Loading Information label is
on the inside of the trunk lid. The label tells you the
proper size, speed rating and recommended inflation
pressures for the tires on your vehicle. It also give you
important information about the number of people
that can be in your vehicle and the total weight you can
carry. This weight is called the vehicle capacity
weight and includes the weigh of all occupants, cargo
and all non-factory installed options. The
other label is the Certification label, found on the
rear edge of the driver’s door. It tells you the gross
weight capacity of your vehicle, called the Gross Vehicle
Weight Rating (GVWR). The GVWR includes the
weight of the vehicle, all occupants, fuel and cargo.
Never exceed the GVWR for your vehicle or the Gross
Axle Weight Rating (GAWR) for either the front or
rear axle.
