1997 BUICK PARK AVENUE brake

Brake System Warning Light
Your Buick’s hydraulic brake system is divided into two
parts. If one part isn’t working, the other part can still
work and stop you. For good braking, though, you need
both parts working well.
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.
BRAKE
This light should come on
when you turn the key to
RUN. If it doesn’t come on
then, have
it fixed so it will
be ready to warn you if
there’s a problem.
I I
Your brake system may not be working properly
if the brake system warning light is on. Driving with the brake system warning light on can lead
to an accident. If the light is still on after you’ve pulled off the road and stopped carefully, have
the vehicle towed for service.
When the ignition is on, the brake system warning light will also come on when you set your parking
brake. The light will stay on if your parking brake
doesn’t release fully. If you try to drive off with the
parking brake set, a chime will also come on until you
release the parking brake.
If the light and chime stay on
after your parking brake
is fully released, it means you
have a brake problem.
If the light and chime come on while you are driving,
pull
off the road and stop carefully. You may notice that
the pedal is harder to push. Or, the pedal may go closer
to the floor. It may take longer to stop. If the light is still
on, have the vehicle towed for service. (See “Towing
Your Vehicle” in the Index.)

Anti-Lock Brake System Warning Light
With the anti-lock brake
system, the light(s) will
come on when you start
your engine and may stay
on for several seconds.
That’s normal.
If the light stays on and the chime sounds, turn the
ignition to
OFF. Or, if the light comes on and the chime
sounds when you’re driving, stop as soon as possible
and turn the ignition
off. Then start the engine again to
reset the system. If the light still stays on and the chime
sounds, or the light comes on again while you’re
driving, your Buick needs service.
If the regular brake
system warning light isn’t on, you still have brakes,
but you don’t have anti-lock brakes. If the regular
brake system warning light is also on, you don’t have
anti-lock brakes and there’s a problem with your regular
brakes. See “Brake System Warning Light” earlier in
this section. The
anti-lock brake system warning light should come
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
ready
to warn you if there is a problem.
Traction Control System Warning Light
(Option)
TRAC
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.

If you turn the system off by pressing the button
located on the end of the shift lever, 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, the warning light will come on and the
chime will sound.
If the traction control system is affected by an
engine related problem, the system will turn off,
the warning light will come on and the chime
will sound.
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.
Engine Coolant Temperature Gage
TEMPERATURE
This gage measures the
temperature of your engine.
If the pointer moves into the
red area, your engine is too
hot.
A temperature indicator
light will turn on and a
chime will sound.
If you have been operating your vehicle under normal
driving conditions and the temperature indicator light
turns on, you should pull off the road, stop your vehicle
and turn off the engine as soon as possible.
The section “Problems on the Road,” in this manual
explains what to do. See “Engine Overheating” in
the Index.

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.
Drunken Driving
Death and injury associated with drinking and driving is
a national tragedy.
It’s the number one contributor to
the highway death toll, claiming thousands of victims
every year.
Alcohol affects four things that anyone needs to drive
a vehicle:
Judgment
0 Muscular Coordination
Vision
0 Attentiveness.

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.
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
Bralung 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 314 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 (1 00 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.

Avoid needless heavy bralung. Some people drive in Anti-Lock Brakes
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 Your
vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent a braking skid.
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. 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.
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.
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.

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 (If Equipped)
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.)
TRAC
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.
I
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.)
