properly if the anti-lock brake system warning
light is flashing. Driving with the anti-lock
brake system warning light flashing can lead
to an accident. After you’ve pulled off the road
and stopped carefully, have the vehicle towed
for service.
If the anti-lock brake system warning light stays on
longer than normal after you’ve started your engine, turn
the ignition off. Or, if the light comes
on and stays on
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, or comes
on again
while you’re driving, your Chevrolet needs service. If
the light is on but not flashing and the regular brake
system warning light isn’t on, you still have brakes, but
you don’t have anti-lock brakes.
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.

may be a problem with your ASR 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 your brakes begin

spark control will continue
to work. The warning light
will not come

following reasons:
If you turn the system off by pressing the switch
located on the instrument panel, the warning light
will come on and stay on and the light
on the switch
will go
out. To turn the system back on, press the
button again. The warning light should go off. (See
“ASR System” in the Index for more information.)
If the temperature of the throttle control begins to rise,
the system will turn off and the warning light will
come
on until the system cools down. The system
does this to prevent damage from overheating.
If the
ASR system warning light comes on and stays on
for an extended period of time when the system is
turned on, your vehicle needs service.
Low Traction Light
When your anti-lock system
is adjusting brake pressure
to help avoid a braking skid,
this light will come on.
LOW
TRAC
If you have the ASR system, this light will also come on
when the system is limiting wheel spin. 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
ASR system stops
limiting wheel spin.
The low traction 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
ASR system is active.

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.
ABS
INOP
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.

make the most
of available tire and road conditions.
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.
You can steer around the obstacle while braking hard.
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.
When your anti-lock system
is adjusting brake pressure
to help avoid a braking skid, this light will come on.

(Option:
LTl V8 Engine)
Your vehicle may have a traction control system called
ASR 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 rear wheels are spinning
or beginning to lose traction. When this happens, the
system works the rear brakes and reduces engine power
(by closing the throttle and managing engine spark)
to
limit wheel spin.
This light will come on
when your ASR system is
limiting wheel spin. See
“Low Traction Light” in
the Index. You may feel or
hear the system working,
but this is normal.
LOW TRAC
Examples of these conditions include a hard acceleration
in a turn, or an abrupt upshift or downshift. Also, when
the compact spare tire is on the rear axle, the ASR
system will cycle and limit acceleration for about the
first
15 seconds of driving after each engine start.
If your vehicle is in cruise control when the ASR
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.)
ASR
OFF
When the system is on,
this warning light will
come on
to let you know
if there’s a problem with
your ASR system. See
“ASR System Warning
Light” in the Index.
The
ASR system may operate on dry roads under some
conditions, and you may notice a reduction in
acceleration when this happens. This is normal and
doesn’t mean there’s a problem with your vehicle. When
this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly.

Page 174 of 404

Downloaded from www.Manualslib.com manuals search engine The ASR 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 ASR 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 switch
on the instrument
panel. The light on the
switch will
go out. The
ASR system warning light will come on and stay
on. If the
ASR system is limiting wheel spin when you
press the switch, 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 switch again. The ASR system warning light should
go off and the light on the switch will come on.
If your car is equipped with P245/5OZR16 tires, the
ASR system will automatically turn off at speeds above
108 mph
(174 kmh). (The ASR system warning light
will not come
on.) When the vehicle speed drops below
103 mph (166 kmh) the system will automatically come
on again.
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.

Downloaded from www.Manualslib.com manuals search engine Some driving conditions or climates may cause a brake
squeal when the brakes are first applied
or lightly
applied. This does not mean something is wrong with
your brakes.
See “Caliper/Knuckle Maintenance Inspection” in
Section
7 of this manual under Part C “Periodic
Maintenance Inspections.”
If you have rear drum brakes, they don’t have wear
indicators, but if you ever hear a rear brake rubbing
noise, have the rear brake linings inspected. Also, the
rear brake drums should be removed and inspected each
time the tires are removed for rotation or changing.
When
you have the front brakes replaced, have the rear
brakes inspected, too.
Brake linings should always be replaced as complete
axle sets.
See “Brake System Inspection” in Section
7 of this
manual under Part
C “Periodic Maintenance
Inspections”.
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in pedal
travel. This could be a sign
of brake trouble.
Brake Adjustment
Every time you make a moderate brake stop, your disc
brakes adjust for wear. If you rarely make a moderate or
heavier stop, then your brakes might not adjust correctly.
If you drive in that way, then
-- very carefully -- make
a few moderate brake stops about every
1,000 miles
(1 600 km), so your brakes will adjust properly.
If your brake pedal goes down farther than normal, your
rear drum brakes may need adjustment. Adjust them by
backing up and firmly applying the brakes a few times.
