Traction Control System Warning Light
(If Equipped: 3800 Supercharged
Engine Only)
TRAC
OFF
The traction control system warning light may come on
for the following reasons:
If you turn the system off by pressing the traction
control button, the warning light will come on and
stay on.
To turn the system back on, press the button
again. The warning light should go off. (See
“Traction Control System” in the Index for
more information.)
If there’s a brake system problem that is specifically
related to traction control, the traction control system
will turn
off and the warning light will come on. If
your brakes begin to overheat, the traction control
system will turn off and the warning light will come
on until your brakes cool down.

Traction Control System Active Light
(If Equipped: 3800 Supercharged
Engine Only)
LOW TRAC
When your traction control
system
is limiting wheel
spin, this light will come on.
Slippery road conditions
may exist if the traction
control system active light
comes on,
so adjust your
driving accordingly.
Low Traction Light
LOW TRAC
When your anti-lock system
is adjusting brake pressure to
help avoid a braking skid,
this light will come on.
(Also see “Anti-Lock Brake
System Active Light” earlier
in this section.)
If
you have the Enhanced Traction System or the Traction
Control System, this light will also come on when the
system is limiting wheel spin. See “Enhanced Traction
System” or “Traction Control System” in the Index.
Slippery road conditions may exist if the low traction
light comes on,
so adjust your driving accordingly. The
light will stay on for a few seconds after the anti-lock
system stops adjusting brake pressure or the Enhanced
Traction System stops limiting wheel spin.
The LOW TRAC light also comes on briefly when
you
turn the ignition key to RUN. If the light doesn’t come
on then, have
it fixed so it will be there to tell you when
the anti-lock brake system or Enhanced Traction System
is active.

Defensive Driving
The best advice anyone can give about driving is:
Drive defensively.
Please start with a
very important safety device in your
Buick: Buckle
up. (See “Safety Belts” in the Index.)
Defensive driving really means “be ready for anything.”
On city streets, rural roads
or freeways, it means
“always expect
the unexpected.”
Assume that pedestrians
or other drivers are going to be
careless and make mistakes. Anticipate what they might
do. Be ready for their mistakes.
Rear-end collisions are about the most preventable
of
accidents. Yet they are common. Allow enough
following distance.
It’s the best defensive driving
maneuver, in both city and rural driving.
You never
know when
the vehicle in front of you is going to brake
or turn suddenly.

Control of 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.
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 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.
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.

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 a little. This is normal.
ANTI -
LOCK
If there’s a problem with the
anti-lock brake system, this
warning light will stay on or
flash. 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.
You slam on the brakes. 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 the
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.
You can steer around the obstacle while braking hard.
As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.
ProCarManuals.com

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.
-‘sing Anti-Lock
uon’t pump the brakes. Just hold the brake pedal
down and let anti-lock work for you. You may feel the
system working, or you may notice some noise, but this
is normal.
LOW TRAC
When your anti-lock system
is adjusting brake pressure
to help avoid
a braking skid,
this light will come on. See
“Anti-Lock Brake System
Active Light” in the Index.
Traction Control System
(With
3800 Supercharged Engine)
Your vehicle has 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.
LOW TRAC
This light will come on
when your traction control
system is limiting wheel
spin. See “Traction Control
System Active Light” in
the Index.
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 cruise control. (See “Cruise Control”
in the Index.)
ProCarManuals.com

Enhanced Traction System (Option: Not
Available with
3800 Supercharged Engine)
Your vehicle may have 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.
TRAC
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.
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
TRACTION
button on the black panel
located directly behind
your automatic transaxle
shift lever.
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.
Magnasteer TM
This steering system provides lighter steering effort for
parking and when driving at low 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 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.
ProCarManuals.com

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.
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.
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 Buick 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.
