PONTIAC GRAND AM 1998 Owners Manual

It’s the amount of alcohol that counts. For example, if
the same person drank three double martinis (3 ounces
or
90 ml of liquor each) within an hour, the person’s
BAC would be close to 0.12 percent. A person who
consumes food just before or during drinking will have a
somewhat lower BAC level.
There is a gender difference, too. Women generally have
a lower relative percentage of body water than men. Since alcohol
is carried
in body water, this means that a
woman generally will reach a higher BAC level than a
man of her same body weight when each has the same
number of drinks.
The law in many U.S. states sets the legal limit at a BAC
of 0.10 percent. In a growing number of U.S. states, and
throughout Canada, the limit
is 0.08 percent. In some
other countries, it’s even lower. The BAC
limit for all
commercial drivers in the United States is 0.04 percent.
The BAC will be over
0.10 percent after three to six
drinks (in one hour). Of course, as we’ve seen, it
depends on how much alcohol is in the drinks, and how
quickly the person drinks them.
But the ability to drive is affected well below a
BAC of
0.10 percent. Research shows that the driving skills of
many people are impaired at a BAC approaching
0.05 percent, and that the effects are worse at night. All
drivers are impaired at BAC levels above 0.05 percent.
Statistics show that the chance
of being in a collision
increases sharply for drivers who have a BAC
of
0.05 percent or above. A driver with a BAC level of
0.06 percent has doubled his or her chance of having a
collision. At
a BAC level of 0.10 percent, the chance of
this driver having a collision is 12 times greater; at a
level of 0.15 percent, the chance is 25 times greater!
4-4

The body takes about an hour to rid itself of the alcohol
in one drink.
No amount of coffee or number of cold
showers
will speed that up. “I’ll be careful” isn’t the
right answer. What
if there’s an emergency, a need to
take sudden action,
as when a child darts into the street?
A person with even a moderate BAC might not be able
to react quickly enough to avoid the collision.
There’s something else about drinking and driving that
many people don’t know. 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.
I
Drinking and then driving is very dangerous.
Your reflexes, perceptions, attentiveness and
judgment can be affected by even
a small amount
of alcohol. You can have a serious -- or even
fatal
-- collision if you drive after drinking.
Please don’t drink and drive
or ride with a driver
who has been drinking. Ride home in
a cab; or if
you’re with a group, designate a driver who will
not drink.

Control of a Vehicle
You have three systems that make your vehicle go where
you WaTlf it ro go. They are the brakes, the steering and
the accelerator.
All three systems have to do their work
at the places where the tires meet the road.
Sometimes, as when you’re driving on snow or ice, it’s
easy to ask more
of those control systems than the tires
and road can provide. That means you can lose control
of your vehicle.
Braking
Braking action involves perception time and
reaction time.
First,
you have to decide to push on the brake pedal.
That’sperception time. Then you have to bring
up your
foot and do it. That’s reaction time.
Average reaction time is about
3/4 of a second. But
that’s 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 314 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’s pavement or
gravel); the condition
of the road (wet, dry, icy); tire
tread; the condition
of your brakes; the weight of the
vehicle and the amount of brake force applied.
4-6

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. Your brakes may not have time to cool between
hard stops. Your 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 engine ever stops while you’re driving, brake
normally but don’t pump your brakes.
If you do, the
pedal may get harder to push down.
If your 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 may take longer to stop and the brake pedal
will be harder to push.
Anti-Lock Brakes (ABS)
Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent a braking
skid.
When you start your engine, or when you begin to drive
away, your anti-lock brake system will check itself. You
may hear
a momentary motor or clicking noise while
this test is going on, and you may even notice that your
brake pedal moves or pulses a little.
This is normal.
If there’s a problem with the
anti-lock brake system,
this
warning light will stay on.
See “Anti-Lock Brake
System Warning Light” in
the Index.

Here’s how anti-lock works. Let’s say the road is wet.
You’re driving safely. Suddenly an animal jumps out
in
front of you. The anti-lock system can change the brake pressure faster
than any driver could. The computer is programmed to
make the most
of available tire and road conditions.
4-8

Remember: Anti-lock doesn’t 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 won’t have time to apply your brakes
if that vehicle suddenly slows or stops. Always leave
enough room up ahead to stop, even though you have
anti-lock brakes.
Using Anti-Lock
Don’t pump the brakes. Just hold the brake pedal down
firmly and let anti-lock work for you. You may feel a
slight brake pedal pulsation
or notice some noise, but
this is normal.
Enhanced Traction System
If your vehicle has the optional four-speed automatic
transaxle,
it also has an Enhanced Traction System
(ETS) that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if it
senses that one
or both of the front wheels are spinning
or beginning to lose traction. When this happens, the
system reduces engine power and may also upshift the
transaxle
to limit wheel spin.
LOW
TRAC
This light will come on
when your Enhanced
Traction System
is limiting
wheel spin. See “Enhanced
Traction System Active
Light” in the Index.
You may
feel or hear the system working, but this
is normal.
The Enhanced Traction System operates
in all transaxle
shift lever positions. But the system can upshift the
transaxle only as high
as the shift lever position you’ve
chosen,
so you should use the lower gears only when
necessary. See “Automatic Transaxle” in the Index.
ETS
OFF
When the system is on and
the parking brake is fully
released,
this warning light
will come on to let you
know
if there’s a problem
with the system.
See “Enhanced Traction System
Warning Light” in the
Index. When
this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.
4-9

To limit wheel spin, especially in slippery road
conditions, you should always leave the Enhanced
Traction System
on. But you can turn the system off if
you ever need to. (You should turn the system off if your
vehicle ever gets stuck in sand, mud, ice
or snow. See
“Rocking Your Vehicle” in
the Index.)
To turn the system on or off,
press the button on the shift
lever knob.
When
you turn the system off, the Enhanced Traction
System warning light will come on
and stay on. If the
Enhanced Traction System is limiting wheel spin when
you press the button to
turn the system off, the warning
light will come on
-- but the system won’t turn off right
away. It
will wait until there’s no longer a current need
to limit wheel spin. You
can turn the system
back on at any time by pressing
the button again. The Enhanced Traction System
warning light should go off.
Braking in Emergencies
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the
very best braking.
Steering
Power Steering
If you lose power steering assist because the engine
stops
or the system is not functioning, you can steer but
it will take much more effort.
Variable Effort Steering (If Equipped)
This steering system provides lighter steering effort for
parking and at low vehicle speeds. Steering effort will
increase at higher speeds for improved road feel.

Steering Tips
Driving on Curves
It’s important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here’s why:
Experienced driver or beginner, each of
us is subject to
the same laws of physics when driving
on curves. The
traction of the tires against the road surface makes it
possible for the vehicle to change its path when you
turn
the fkont wheels. If there’s no traction, inertia will keep \
the vehicle going in the same direction. If you’ve ever
tried to steer a vehicle on wet ice, you’ll understand this\
.
The traction you can get in a curve depends on the
condition of your tires and the road surface, the angle at
which the curve is banked, and your
speed. While you’re
in a curve, speed is the one factor you can control. Suppose you’re steering through
a sharp curve. Then you
suddenly accelerate. Both control systems
-- steering and
acceleration
-- have to do their work where the tires meet
the road.
Adding the sudden acceleration can demand too
much of those places.
You can lose control. Refer to
“Enhanced Traction System”
in the Index.
What should you do
if this ever happens? Ease up on the
accelerator pedal, steer the vehicle the way you want it
to go, and slow down.
Speed limit signs near curves warn that you should
adjust your speed. Of course, the posted speeds
are
based on good weather and road conditions. Under less
favorable conditions you’ll want to go slower.
If you need to reduce your speed as you approach a
curve, do it before you enter the curve, while your front
wheels are straight ahead.
Try to adjust your speed so you can “drive” through the
curve. Maintain a reasonable, steady speed. Wait to
accelerate until you are out
of the curve, and then
accelerate gently into the straightaway.
4-11

Steering in Emergencies
There are times when steering can be more effective
than braking. For example, you come over a hill and
find a truck stopped
in your lane, or a car suddenly pulls
out
from nowhere, or a child darts out from between
parked
cars and stops right in front of you. You can
avoid these problems by
braking -- if you can stop in
time. But sometimes you can’t; there isn’t room.
That’s the time for evasive action
-- steering around
the problem.
Your vehicle can perform very well in emergencies like
these. First apply your brakes. (See “Braking in
Emergencies” earlier in this section.) It is better to
remove
as much speed as you can from a possible
collision. Then
steer around the problem, to the left or
right depending on the space available.
An emergency like this requires close attention and a
quick decision.
If you are holding the steering wheel at
the recommended
9 and 3 o’clock positions, you can
turn it a full 180 degrees very quickly without removing
either hand. But you have to act fast, steer quickly, and
just
as quickly straighten the wheel once you have
avoided
the object.
The fact that such emergency situations
are always
possible is a good reason to practice defensive driving at
all times and wear safety belts properly.

Off-Road Recovery
You may find that your right wheels have dropped off the
edge of a
road onto the shoulder while you’re driving.
If the level of the shoulder is only slightly below the
pavement, recovery should
be fairly easy. Ease off the
accelerator and then,
if there is nothing in the way, steer so
that your vehicle straddles the edge of the pavement. You
can tum the steering wheel up to one-quarter turn until the
right fkont tire contacts the pavement edge. Then turn your
steering wheel to go straight down the roadway.
Passing
The driver of a vehicle about to pass another on a
two-lane highway waits for just the right moment,
accelerates, moves around the vehicle ahead, then
goes
back into the right lane again. A simple maneuver?
Not necessarily! Passing another vehicle on a two-lane
highway is a potentially dangerous move, since the
passing vehicle occupies the same lane
as oncoming
trafEc for several seconds.
A miscalculation, an error in
judgment, or
a brief surrender to frustration or anger can
suddenly
put the passing driver face to face with the
worst of all tr&k accidents -- the head-on collision.
So here are some tips for passing:
“Drive ahead.” Look down the road, to the sides and to
crossroads for situations that might affect your passing
patterns. If you have any doubt whatsoever about
making a successful pass, wait for a better time.
Watch for traffic signs, pavement markings and lines.
If you can see a sign up ahead that might indicate a
turn or an intersection, delay your pass. A broken
center line usually indicates it’s all right to pass (providing the road ahead is clear). Never
cross a solid
line on your side of the lane or a double solid line,
even if the road seems empty of approaching traffic.
