following reasons: Low Traction Light
If you turn the system off by pressing the button
located on the console near the cigarette lighter, 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 “ASR System” in the Index
for more information.)
0 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. When your anti-lock
system is adjusting brake pressure to help avoid a braking skid, the LOW TRAC light will
appear on your instrument cluster. 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 this 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 TRAC light also comes on briefly, as a bulb
check, when
the engine is started. 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.

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. 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.
To Use 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, the LOW TRAC
light will come on. See
“Low Traction Light” in the
Index.
Downloaded from www.Manualslib.com manuals search engine ASR (Acceleration Slip Regulation) System
(Option: LT1 VS 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.
The
LOW TRAC light will come on when your ASR
system is limiting wheel spin, See “Low Traction Light”
in the Index. You may feel the system working, or you
may notice some noise, but this is normal.
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.
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,
the ASR OFF 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.
When
this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly.
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 button
on the console
near the cigarette lighter.

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
ASR 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.

Downloaded from www.Manualslib.com manuals search engine 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 Chevrolet’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
ASR system, remember: It helps avoid
only the acceleration skid. If you
do not have ASR, 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.
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.

Downloaded from www.Manualslib.com manuals search engine Uniform Tire Quality Grading
I The following information relates to the system
I developed by the United States National Highway
i Traffic Safety Administration which grades tires by
~ treadwear, traction and temperature performance. (This
applies only to vehicles sold in the United States.)
Treadwear
The treadwear grade is a comparative rating based on
the wear rate
of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded 150 would wear one and a half
(1 1/2) times as well on the government course as a tire
graded
100. The relative performance of tires depends
upon the actual conditions of their use, however, and
may depart significantly from the norm due to variations
in driving habits, service practices and differences in
road characteristics and climate.
Traction - A, B, C
The traction grades, from highest to lowest are: A, B,
and C. They represent the tire’s ability to stop on wet
pavement as measured under controlled conditions
on
specified government test surfaces of asphalt and
concrete. A tire marked
C may have poor traction
performance.
Warning: The traction grade assigned to this tire is based
on braking (straight-ahead) traction tests and does not
include cornering (turning) traction.
