PONTIAC GRAND PRIX 2003 Owners Manual

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.
4-33

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.

1 TIRE-LOADING INFORMATION
1 OCCUPANTS VEHiCLE 6
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.
4-35

If you do have a heavy load, spread it out. Don’t carry
more than
167 pounds (75 kg) in your trunk.
~ 3 not load your vehicle any heavier than the
GVWR, or either the maximum front or rear
GAWR. If you do, parts on your vehicle can
break, and
it can change the way your vehicle
handles. These could cause you to lose
control and crash.
Also, overloading can
shorten the life of your vehicle.
Notice: Your warranty does not cover parts or
components that fail because
of overloading.
If you put things inside your vehicle - like suitcases,
tools, packages or anything else - they will go as
fast as the vehicle goes. If you have to stop or
turn quickly,
or if there is a crash, they’ll keep going. Things you
put insi your
ve--.:le can s.. .. and injure people in a sudden stop or turn,
or in a crash.
Put things in the trunk of your vehicle.
In a trunk, put them as far forward as you
can. Try to spread the weight evenly.
Never stack heavier things, like suitcases,
inside the vehicle
so that some of them
are above the tops of the seats.
Don’t leave an unsecured child restraint in
your vehicle.
When you carry something inside the
vehicle, secure
it whenever you can.
Don’t leave a seat folded down unless you
need to.

Towing a Trailer
If you don’t use the correct eq+ment 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. You may also damage your
vehicle; the resulting repairs would not be
covered by your warranty. Pull a trailer only if
you have followed all the steps
in this section.
Ask your dealer for advice and information
about towing a trailer with your vehicle. Your
vehicle can tow a trailer
if it is equipped with the
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 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.
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.

If You Do Decide To Pull A Trailer
If you do, here are some important points:
e
e
e

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.
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:
e the weight of the trailer,
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
1000 Ibs (454 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.

Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important weight
to measure because it affects the total or gross weight
of your vehicle. The Gross Vehicle Weight (GWV)
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 tow a trailer, you must add the
tongue load to the GVW because your vehicle will
be carrying that weight, too. See Loading Your Vehicle
on page 4-35 for more information about your
vehicle’s maximum load capacity.
A
If you’re using a weight-carrying hitch or a
weight-distributing hitch, the trailer tongue
(A) should
weigh
10-15 percent 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 upper limit
for cold tires. You’ll find these numbers on the Tire
Loading Information label, found on the inside of
the trunk lid,
or see Loading Your Vehicle on page 4-35.
Then be sure you don’t go over the GVW limit for
your vehicle, including the weight of the trailer
tongue.
