PONTIAC BONNEVILLE 2003 Owners Manual

I
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
0.1 2 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 an increasing number of
U.S. states, and
throughout Canada, sets the legal limit at
0.08 percent.
In some other countries, the limit is even lower. For
example, it is
0.05 percent in both France and Germany.
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.
“1’11 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 ef being killed or
permanently disabled is higher than if the person had
not been drinking. Drinking and then driving
is very dangerous.
Your reflexes, perceptions, attentiveness and
judgement 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 sf a Vehicle
You have three systems that make your vehicle
go where you want it to 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.
Also see Traction Control System
(TCS)
on page 4-9.
Braking
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake pedal.
That’s
perception 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
3/4 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.
4-6

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.
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 Brake System (ABS)
Your vehicle has anti-lock brakes. 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.
ANTI-
LOCK
United States
Canada
If there’s a problem with the anti-lock brake system, this
warning light will stay on. See
Anti-Lock Brake System
Warning Light
on page 3-43.
4-7

Let’s say the road is wet and you’re driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here’s 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 front wheel
and at both rear wheels.
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. This can help you steer around the obstacle
while braking hard.
4-a

As you brake, your computer keeps receiving updates
on wheel speed and controls braking pressure
accordincjy.
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.
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.
Traction Control System (TCS)
Your vehicle may have a traction control system 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 works the front brakes and reduces engine
power
to limit wheel spin.
You may feel or hear the system working, but this
is normal.
If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow you to safely use it again, you may
reengage the crake contro!. See ‘Cruise Control” under
Turn Signal/Muitifunction Lever on page 3-7.

TRAC
OFF
This light should come on
briefly when you start the
engine.
If it stays on or
comes on while you
are driving, there’s a
problem with your traction
control system.
See
Traction Control System (TCS) Warning Light on
page 3-43. When this warning light is on, the system will
not limit wheel spin. Adjust your driving accordingly.
The traction control system automatically comes
on whenever you start your vehicle.
To limit wheel spin,
especially in slippery road conditions, you should
always leave the system on. But you can turn the
traction control system
off if you ever need to. You
should turn the system
off if your vehicle ever gets stuck
in sand, mud or snow and rocking the vehicle is
required. See “Rocking Your Vehicle To Get It Out”
under
If You Are Stuck: In Sand, Mud, Ice or Snow on
page 4-30.
To turn the system off,
press the TRACTION
CONTROL button located
on the instrument panel
under the comfort controls.
The traction control system warning light in the
instrument cluster will come on and stay on.
If the
system is limiting wheel spin when you press the button,
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 traction control system
warning light should
go off.
The switch indicator light should go back on.

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.
Magnetic Speed Variable Assist
Steering
Your vehicle may have this optional steering system
that continuously adjusts the effort you feel when
steering at all vehicle speeds.
It provides ease when
parking, yet a firm, solid feel at highway speeds.
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
rl- I L --Y^Y ^Y ^. .- .-- l~l,,,’, ... L. .. LI IC I ICVV~ I lappc1 I VI I clul vca. I ICI G a VVI ~y.
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 front 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. See
Traction Control
System (TCS) on page 4-9.
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.
If you have Stabilitrak@, you may see the STABILITY
SYSTEM ACTIVE message on the Driver Information
Center. See “Stability System Active Message”
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.

4-1 1

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.
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 on page 4-6. 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.
4-1 3

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 turn the steering wheel up to
one-quarter turn until the right front 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
traffic 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 traffic 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).
a double solid line, even
if the road seems empty
of approaching traffic.
