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.

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 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 Chevrolet 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. An
emergency like this requires close attention
and a
quick decision. If you are holding the steering wheel at
the recommended 9 and 3 o’clock positions, you can
turn it a full 180 degrees very quickly without removing
either hand. But you have
to act fast, steer quickly, and
just as quickly straighten the wheel once you have
avoided the object.
The fact that such emergency situations are always
possible is a good reason
to practice defensive driving at
all times and wear safety belts properly.

traffic.
Do not get too close to the vehicle you want to
pass while you’re awaiting an opportunity. For
one thing, following too closely reduces your area
of vision, especially if you’re following a larger
vehicle. Also, you won’t have adequate space if the
vehicle ahead suddenly slows or stops. Keep back
a
reasonable distance.
When it looks like a chance to pass is coming up,
start to accelerate but stay in the right lane and
don’t get too close. Time your move
so you will be
increasing speed as the time comes to move into the
other
lane. If the way is clear to pass, you will have
a “running start” that more than makes up for the
distance you would lose by dropping back. And if
something happens to cause you to cancel your pass,
you need only slow down and drop back again and
wait for another opportunity.
If other cars are lined up to pass a slow vehicle, wait
your turn. But take care that someone isn’t trying to
pass you as
you pull out to pass the slow vehicle.
Remember
to glance over your shoulder and check
the blind spot.
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.)
Try not to pass more than one vehicle at a time
on two-lane roads. Reconsider before passing the
next vehicle.
Don’t overtake a slowly moving vehicle too rapidly.
Even though
the brake lamps are not flashing, it
may be slowing down or starting to turn.
If you’re being passed, make it easy for the
following driver
to get ahead of you. Perhaps you
can ease a little to the right.

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 If you drive regularly in steep country, or if you’re
planning to visit there, here are some tips that can
make
your trips safer and more enjoyable.
Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system
and transmission. These parts can work hard on
mountain roads.
0 Know how to go down hills. The most important
thing to know
is this: let your engine do some of the
slowing down. Shift
to a lower gear when you go
down a steep or long hill.
If you don’t shift down, your brakes could get
so hot that they wouldn’t work well. You would
then have poor braking or even none going
down a hill. You could crash. Shift down to let
your engine assist your brakes on a steep
downhill slope. Coasting downhill in
NEUTRAL (N) or
with the
ignition
off is dangerous. Your brakes will have to
do all the work of slowing down. They could get so
hot that they wouldn’t work well. You would then
have poor braking or even none going
down a hill.
You could crash. Always have your engine running
and your vehicle in gear when you go downhill.

Know how to go uphill. You may want to shift down
to a lower gear. The lower gears help cool your engine
and transmission, and you can climb the hill better.
Stay in your own lane when driving
on two-lane
roads in hills or mountains. Don’t swing wide or cut
across the center
of the road. Drive at speeds that let
you stay in your own lane.
As you go over
the top of a hill, be alert. There
could be something in your lane, like a stalled car
or an accident.
You may see highway signs on mountains that
warn of
special problems. Examples are long grades, passing or
no-passing zones, a falling rocks area or winding
roads. Be alert to these and take appropriate action.
