Police records show that
almost 40 percent of all motor
vehicle-related deaths involve
alcohol. In most cases, these deaths
are the result of someone who
was drinking and driving. In recent
years, more than 17,000 annual
motor vehicle-related deaths have
been associated with the use of
alcohol, with about 250,000 people
injured.
For persons under 21, it is against
the law in every U.S. state to
drink alcohol. There are good
medical, psychological, and
developmental reasons for
these laws.
The obvious way to eliminate the
leading highway safety problem
is for people never to drink alcohol
and then drive.
Medical research shows that alcohol
in a person’s system can make crash
injuries worse, especially injuries
to the brain, spinal cord, or heart.This means that when anyone who
has been drinking — driver or
passenger — is in a crash, that
person’s chance of being killed or
permanently disabled is higher than
if the person had not been drinking.
Control of a Vehicle
The following three systems help
to control your vehicle while
driving — brakes, steering, and
accelerator. At times, as when
driving on snow or ice, it is easy to
ask more of those control systems
than the tires and road can provide.
Meaning, you can lose control of
your vehicle.
Adding non-dealer/non-retailer
accessories can affect your vehicle’s
performance. SeeAccessories
and Modifications on page 9-3.
Braking
SeeBrake System Warning Light on
page 4-16.
Braking action involves perception
time and reaction time. First,
you have to decide to push on the
brake pedal. That is perception time.
Then you have to bring up your
foot and do it. That is reaction time.
Average reaction time is about
three-fourths of a second. But that is
only an average. It might be less with
one driver and as long as two or
three seconds or more with another.
Age, physical condition, alertness,
coordination, and eyesight all play a
part. So do alcohol, drugs, and
frustration. But even in three-fourths
of a second, a vehicle moving at
60 mph (100 km/h) travels 66 feet
(20 m). That could be a lot of
distance in an emergency, so
keeping enough space between your
vehicle and others is important.

And, of course, actual stopping
distances vary greatly with the
surface of the road, whether it is
pavement or gravel; the condition of
the road, whether it is wet, dry, or
icy; tire tread; the condition of
the brakes; the weight of the
vehicle; and the amount of brake
force applied.
Avoid needless heavy braking.
Some people drive in
spurts — heavy acceleration
followed by heavy braking — rather
than keeping pace with traffic.
This is a mistake. The brakes might
not have time to cool between
hard stops. The brakes will wear out
much faster if you do a lot of heavy
braking. If you keep pace with
the traffic and allow realistic
following distances, you will
eliminate a lot of unnecessary
braking. That means better braking
and longer brake life.If your vehicle’s engine ever stops
while you are driving, brake normally
but do not pump the brakes.
If you do, the pedal could get harder
to push down. If the engine stops,
you will still have some power brake
assist. But you will use it when
you brake. Once the power assist is
used up, it can take longer to
stop and the brake pedal will be
harder to push.
Adding non-dealer/non-retailer
accessories can affect your vehicle’s
performance. SeeAccessories
and Modifications on page 9-3.Antilock Brake
System (ABS)
Your vehicle has the Antilock
Brake System (ABS), an advanced
electronic braking system that
will help prevent a braking skid.
When you start the engine and
begin to drive away, ABS will check
itself. You might hear a momentary
motor or clicking noise while this
test is going on, and you might even
notice that the brake pedal moves
a little. This is normal.
If there is a problem with ABS,
this warning light will stay on.

Warning Light on page 4-17.
Let us say the road is wet and you
are driving safely. Suddenly, an
animal jumps out in front of you.
Driving and Operating 8-15
2008 - Pontiac G8 Owner Manual
You slam on the brakes and
continue braking. Here is what
happens with ABS:
A computer senses that wheels
are slowing down. If one of
the wheels is about to stop rolling,
the computer will separately
work the brakes at each wheel.
ABS can change the brake pressure
faster than any driver could.
The computer is programmed to
make the most of available tire and
road conditions. This can help
you steer around the obstacle while
braking hard.
As you brake, the computer keeps
receiving updates on wheel speed
and controls braking pressure
accordingly.Remember: ABS does not change
the time you need to get your
foot up to the brake pedal or always
decrease stopping distance.
If you get too close to the vehicle in
front of you, you will not have
time to apply the brakes if that
vehicle suddenly slows or stops.
Always leave enough room up
ahead to stop, even though
you have ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down rmly and
let antilock work for you. You might
hear the antilock pump or motor
operate, and feel the brake
pedal pulsate, but this is normal.
Braking in Emergencies
With ABS, you can steer and
brake at the same time. In many
emergencies, steering can help
you more than even the very
best braking.
Electronic Stability
Program
The vehicle has the Electronic
Stability Program (ESP®) that
assists with directional control of the
vehicle in difficult driving conditions
by reducing engine power and
applying the brakes to individual
wheels. This is especially useful
in slippery road conditions.
The system operates if it senses
that the rear wheels are spinning
too much, are beginning to lose
traction or if it senses that the
vehicle is not moving in its intended
direction. It turns on automatically
every time the vehicle is started.
When ESP is working, this light
and the STABILITY CONTROL
ASSISTANCE message will come
