2005 PONTIAC GRAND AM anti lock

A cornering skid is best handled by easing your foot off
the accelerator pedal.
If you have the Enhanced Traction System, remember:
It helps to avoid only the acceleration skid. If you do
not have the Enhanced Traction System, or if the system
is off, then an acceleration skid is also best handled
by easing your foot off the accelerator pedal.
If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want
the vehicle to go. If you start steering quickly enough,
your vehicle may straighten out. Always be ready
for a second skid if it occurs.
Of course, traction is reduced when water, snow, ice,
gravel, or other material is on the road. For safety, you
will want to slow down and adjust your driving to
these conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration,
or braking, including engine braking by shifting to a
lower gear. Any sudden changes could cause the tires
to slide. You may not realize the surface is slippery
until your vehicle is skidding. Learn to recognize warning
clues — such as enough water, ice, or packed snow
on the road to make a mirrored surface — and
slow down when you have any doubt.
If you have the anti-lock braking system, remember: It
helps avoid only the braking skid. If you do not have
anti-lock, then in a braking skid, where the wheels are
no longer rolling, release enough pressure on the brakes
to get the wheels rolling again. This restores steering
control. Push the brake pedal down steadily when
you have to stop suddenly. As long as the wheels are
rolling, you will have steering control.

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
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. 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 enhanced traction, it will improve your ability
to accelerate when driving on a slippery road. Even
though your vehicle has an enhanced 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 enhanced traction system off, such as
when driving through deep snow and loose gravel,
to help maintain vehicle motion at lower speeds. See
Enhanced Traction System (ETS) on page 4-8.
Unless you have the anti-lock braking system, you will
want to brake very gently, too. If you do have anti-lock,
seeAnti-Lock Brake System (ABS) 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 will 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.
4-26

Remember, unless you have anti-lock, 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 fine
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:
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 flashers.
•Tie a red cloth to your vehicle to alert police that
you have been stopped by the snow.

Hitches
It is 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:
•The rear bumper on your vehicle is not intended for
hitches. Do not attach rental hitches or other
bumper-type hitches to it. Use only a
frame-mounted hitch that does not attach to the
bumper.
•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 to seal the holes later when
you remove the hitch. If you do not seal them,
deadly carbon monoxide (CO) from your exhaust
can get into your vehicle. SeeEngine Exhaust
on page 2-26. Dirt and water can, too.
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 and do not attach them to the bumper.
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 will be able to install, adjust and maintain
them properly. And because you may have anti-lock
brakes, do not try to tap into your vehicle’s brake system.
If you do, both systems will not work well, or at all.

Vehicle Data Collection and Event
Data Recorders
Your vehicle, like other modern motor vehicles, has a
number of sophisticated computer systems that monitor
and control several aspects of the vehicle’s performance.
Your vehicle uses on-board vehicle computers to monitor
emission control components to optimize fuel economy,
to monitor conditions for airbag deployment and, if so
equipped, to provide anti-lock braking and to help the
driver control the vehicle in difficult driving situations.
Some information may be stored during regular
operations to facilitate repair of detected malfunctions;
other information is stored only in a crash event by
computer systems, such as those commonly called event
data recorders (EDR).
In a crash event, computer systems, such as the Airbag
Sensing and Diagnostic Module (SDM) in your vehicle
may record information about the condition of the vehicle
and how it was operated, such as data related to
engine speed, brake application, throttle position, vehicle
speed, safety belt usage, airbag readiness, airbag
performance, and the severity of a collision. If your
vehicle is equipped with Quadrasteer, steering
performance, including yaw rate, steering wheel angle,
and lateral acceleration, is also recorded. This
information has been used to improve vehicle crash
performance and may be used to improve crash
performance of future vehicles and driving safety. Unlikethe data recorders on many airplanes, these on-board
systems do not record sounds, such as conversation of
vehicle occupants.
To read this information, special equipment is needed
and access to the vehicle or the device that stores
the data is required. GM will not access information
about a crash event or share it with others other than:
•with the consent of the vehicle owner or, if the
vehicle is leased, with the consent of the lessee,
•in response to an official request of police or similar
government office,
•as part of GM’s defense of litigation through the
discovery process, or
•as required by law.
In addition, once GM collects or receives data, GM may:
•use the data for GM research needs,
•make it available for research where appropriate
confidentiality is to be maintained and need is
shown, or
•share summary data which is not tied to a specific
vehicle with non-GM organizations for research
purposes.
Others, such as law enforcement, may have access to
the special equipment that can read the information if
they have access to the vehicle or the device that stores
the data.
