PONTIAC GRAND PRIX 2007 Owners Manual

Page 311 of 526

Stay in your own lane when driving on two-lane
roads in hills or mountains. Do not swing wide
or cut across the center of the road. Drive at
speeds that let you stay in your own lane.
As you go over the top of a hill, be alert. There
could be something in your lane, like a stalled
car or an accident.
You may see highway signs on mountains that
warn of special problems. Examples are long
grades, passing or no-passing zones, a falling
rocks area, or winding roads. Be alert to these
and take appropriate action.
Winter Driving
Here are some tips for winter driving:
Have your vehicle in good shape for winter.
You may want to put winter emergency
supplies in your trunk.
Also seeTires on page 400.

Include an ice scraper, a small brush or broom, a
supply of windshield washer uid, a rag, some
winter outer clothing, a small shovel, a ashlight,
a red cloth, and a couple of reective 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.
Driving on Snow or Ice
Most of the time, those places where the tires
meet the road probably have good traction.
However, if there is snow or ice between the
tires and the road, you can have a very slippery
situation. You will have a lot less traction, or grip,
and will need to be very careful.
What is the worst time for this? Wet ice. Very cold
snow or ice can be slick and hard to drive on.
312

Page 313 of 526

But wet ice can be even more trouble because it
may offer the least traction of all. You can get
wet ice when it is 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.
Whatever the condition — smooth ice, packed,
blowing, or loose snow — drive with caution.
If you have the Traction Control System (TCS) or
the Enhanced Traction System (ETS), it will
improve your ability to accelerate when driving on
a slippery road. Even though your vehicle has a
traction system you will want to slow down and
adjust your driving to the road conditions. Under
certain conditions, you may want to turn the TCS or
ETS off, such as when driving through deep snow
and loose gravel, to help maintain vehicle motion at
lower speeds. SeeTraction Control System (TCS)
on page 292orEnhanced Traction System (ETS)
on page 293.
If you do not have TCS or ETS, 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 Brake System
(ABS), you will want to brake very gently, too.If you do have ABS, seeAnti-Lock Brake System
(ABS) on page 289. This system improves your
vehicle’s stability when you make a hard stop on a
slippery road. Whether you have ABS or not, you
will want to begin stopping sooner than you would
on dry pavement. Without ABS, 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 ABS, if you brake so
hard that your wheels stop rolling, you will 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
ne until you hit a spot that is covered with ice.
On an otherwise clear road, ice patches may
appear in shaded areas where the sun cannot
reach, such as 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 are
actually on the ice, and avoid sudden steering
maneuvers.

If You Are 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. Here
are some things to do to summon help and keep
yourself and your passengers safe:
Turn on your hazard ashers.
Tie a red cloth to your vehicle to alert police that
you have been stopped by the snow.
Put on extra clothing or wrap a blanket around
you. If you do not have blankets or extra
clothing, make body insulators from
newspapers, burlap bags, rags, oor
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.
314

Page 315 of 526

{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 cannot 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
does not collect there.
Open a window just a little on the side of
the vehicle that is 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 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 Your Vehicle is 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 do not
want to spin your wheels too fast. The method
known as rocking can help you get out when
you are stuck, but you must use caution.
{CAUTION:
If you let your vehicle’s tires spin at high
speed, they 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
re or other damage. When you are stuck,
spin the wheels as little as possible. Do not
spin the wheels above 35 mph (55 km/h) as
shown on the speedometer.Notice:Spinning the wheels can destroy parts
of your vehicle as well as the tires. If you spin
the wheels too fast while shifting the transaxle
back and forth, you can destroy the transaxle.
SeeRocking Your Vehicle to Get It Out on
page 316.
For information about using tire chains on your
vehicle, seeTire Chains on page 421.
Rocking Your Vehicle to Get It Out
First, turn the steering wheel left and right.
That will clear the area around the front wheels.
If your vehicle has traction control, you should turn
the traction control system off. SeeTraction
Control System (TCS) on page 292. 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 transaxle is in gear. By slowly spinning
the wheels in the forward and reverse directions,
you will cause a rocking motion that may free your
vehicle. If that does not get your vehicle out
after a few tries, it may need to be towed out. If
your vehicle does need to be towed out, see
Towing Your Vehicle on page 322.

Loading Your Vehicle
It is very important to know how much weight
your vehicle can carry. Two labels on your vehicle
show how much weight it may properly carry,
the Tire and Loading Information label and
the Vehicle Certication label.
{CAUTION:
Do not load your vehicle any heavier than
the Gross Vehicle Weight Rating (GVWR),
or either the maximum front or rear Gross
Axle Weight Rating (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.
Tire and Loading Information Label
A vehicle specic Tire and Loading Information
label is attached to the vehicle’s center pillar
(B-pillar). With the driver’s door open, you will nd
the label attached below the door lock post (striker).
The Tire and Loading Information label lists the
number of occupant seating positions (A), and the
maximum vehicle capacity weight (B) in kilograms
and pounds. The vehicle capacity weight includes
the weight of all occupants, cargo, and all
nonfactory-installed options.
Label Example
317

Page 318 of 526

The Tire and Loading Information label also lists the
tire size of the original equipment tires (C) and the
recommended cold tire ination pressures (D). For
more information on tires and ination, seeTires on
page 400andInation - Tire Pressure on page 408.
There is also important loading information on the
Certication label. It tells you the Gross Vehicle
Weight Rating (GVWR) and the Gross Axle Weight
Rating (GAWR) for the front and rear axle, see
“Certication Label” later in this section.
Steps for Determining Correct Load Limit
1. Locate the statement “The combined
weight of occupants and cargo should
never exceed XXX kg or XXX lbs” on your
vehicle’s placard.
2. Determine the combined weight of the driver
and passengers that will be riding in your
vehicle.
3. Subtract the combined weight of the driver
and passengers from XXX kg or XXX lbs.4. The resulting gure equals the available
amount of cargo and luggage load capacity.
For example, if the “XXX” amount equals
1400 lbs and there will be ve 150 lb
passengers in your vehicle, the amount of
available cargo and luggage load capacity is
650 lbs (1400−750 (5 x 150) = 650 lbs).
5. Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in Step 4.
6. If your vehicle will be towing a trailer, the load
from your trailer will be transferred to your
vehicle. Consult this manual to determine how
this reduces the available cargo and luggage
load capacity for your vehicle.
If your vehicle can tow a trailer, seeTowing a
Trailer on page 324for important information
on towing a trailer, towing safety rules, and
trailering tips.

Refer to your vehicle’s Tire and Loading Information
label for specic information about your vehicle’s
maximum vehicle capacity weight and seating
positions. The combined weight of the driver,
passengers, and cargo should never exceed your
vehicle’s maximum vehicle capacity weight.
Certication Label
A vehicle specic Certication label is found on
the rear edge of the driver’s door.
The label shows 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.
