traction control BUICK PARK AVENUE 1996 Owners Manual

Cruise Control
With cruise control, you can
maintain a speed
of about
25 mph (40 kmb) or more
without keeping your foot
on the accelerator. This can
really help on long trips.
Cruise control does not work
at speeds below about
25 mph (40 km/h).
When you apply your brakes, the cruise control
shuts
off.
Cruise control can be dangerous where you
can’t drive safely at
a steady speed. So,
don’t use your cruise control on winding
roads or in heavy traffic.
slippery roads.
On such roads, fast changes
in tire traction can cause needless wheel
spinning, and you could lose control. Don’t
use cruise control on slippery roads.
Cruise control can be dangerous on
If your vehicle is in cruise control when the optional
traction control system begins to limit wheel spin,
the cruise control will automatically disengage. (See
“Traction Control System” in the Index.) When road
conditions allow you to safely use it again, you may
turn
the cruise control back on.

Traction Control System Warning Light
(Option)
TRACTION
OFF
This warning light should
come on briefly as you start
the engine. If the warning
light doesn’t come on then,
have
it fixed so it will be
ready to warn you if there’s
a problem.
If it stays on, or comes on when you’re driving, there
may be a problem with your traction control system and
your vehicle may need service. When this warning light
is on, the system will not limit wheel
spin. Adjust your
driving accordingly. The
traction control system warning light may come on
for the following reasons:
If you turn the system off by pressing the button
located on the instrument panel, left of the steering
column, 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.)
0 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.
If the traction control system is affected by an
engine-related problem, the system will turn
off and
the warning light will come on.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.

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 and let anti-lock work for you. You may feel the system
working, or you may notice some noise, but this is normal.
Traction Control System (Option)
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
re-engage the cruise control. (See “Cruise Control” in
the Index.)
TRACTION
OFF
When the system is on, this
warning light will come on
to let you know if there’s a
problem with your traction
control system.
See “Traction Control System Warning Light” in the
Index. 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, ice or snow. See “Rocking Your Vehicle”
in the Index.)

To turn the system off, press
the button on the instrument
panel to the left of the
steering wheel.
The traction control system warning light 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.
Braking in Emergencies
Use your anti-lock braking system when you need to.
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 (Option)
Your vehicle may be equipped with GM Magnasteer TM ,
a 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
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.

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. Unless you have traction control and the system
is on, 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.
L Erne ncie!
There are times when steenng can De 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 chld 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.

0 Check your mirrors, glance over your shoulder, and
start your left lane change signal before moving out
of the right lane to pass. When you are far enough
ahead
of the passed vehicle to see its front in your
inside mirror, activate your right lane change signal
and move back into the right lane. (Remember that
your right outside mirror is convex. The vehicle you
just passed may seem
to be farther away from you
than it really is.)
0 Try not to pass more than one vehicle at a time on
two-lane roads. Reconsider before passing the
next vehicle.

Loss of Control
Let’s review what driving experts say about what
happens when the three control systems (brakes, steering
and acceleration) don’t have enough friction where the
tires meet the road to do what the driver has asked.
In any emergency, don’t give up. Keep trying to steer and
constantly seek an escape route or area of less danger.
Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not “overdriving”\

those conditions. But skids are always possible.
The three types of skids correspond
to your Buick’s
three control systems. In the braking skid, your wheels
aren’t rolling. In the steering or cornering skid, too
much speed or steering in a curve causes tires to slip and
lose cornering force. And in the acceleration skid, too
much throttle causes the driving wheels to spin.
A cornering skid is best handled by easing your foot off
the accelerator pedal.
If you have the traction control system, remember: It
helps avoid only the acceleration skid.
If
you do not have traction control, 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.
ProCarManuals.com

Of course, traction is reduced when water, snow, ice,
gravel or other material is on the road. For safety, you’ll
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.
Remember: Any anti-lock brake system (ABS) helps avoid only the braking skid.
Night driving
is more dangerous than day driving. One
reason is that some drivers are likely to be impaired
-- by
alcohol or drugs, with night vision problems, or by fatigue.

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’ll
have a lot less traction or “grip” and will need to be
very careful.
i
What’s 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’s 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 traction control, keep the system on. It will
improve your ability
to accelerate when driving on a
slippery road. Even though your vehicle has a traction
control system, you’ll want to slow down and adjust
your driving to the road conditions. See “Traction
Control System” in the Index.
If you don’t have the traction control system, accelerate
gently. Try not to break the fragile traction.
If you
accelerate too fast,
the drive wheels will spin and polish
the surface under the tires even more.

If You’re Stuck: In Sand, Mud,
Ice
or Snow
What you don’t want to do when your vehicle is stuck is
to spin your wheels too fast. The method known as
“rocking” can help you get out when you’re stuck, but
you must use caution.
If you let your tires SI at high speed, they can
explode,
and you or others could be injured. And,
the transaxle or other parts
of the vehicle can
overheat. That could cause an engine
compartment fire or other damage. When you’re
stuck, spin the wheels as little as possible. Don’t
spin the wheels above
35 mph (55 km/h) as shown
on the speedometer.
I NOTICE:
Spinning your wheels can destroy parts of your
vehicle as well as the tires.
If you spin the wheels
too fast while shifting your transaxle back and
forth, you can destroy your transaxle.
For information about using tire chains on your vehicle,
see “Tire Chains” in the Index.
Rocking your vehicle
to get it out:
First, turn your steering wheel left and right. That will
clear the area around your front wheels. If your vehicle
has traction control, you should turn the system off. (See
“Traction Control System” in the Index.) Then shift
back and forth between REVERSE (R) and a forward
gear, spinning the wheels
as little as possible. Release
the accelerator pedal while
you shift, and press lightly
on the accelerator pedal when the transaxle is in gear. If
that doesn’t get you out after a few tries, you may need
to be towed out. If you do need to be towed out, see
“Towing Your Vehicle” in the Index.
