I
Drinking and then driving is very dangerous.
Your reflexes, perceptions, attentiveness and
judgment can be affected by even a small amount
of alcohol. You can have a serious
-- or even
fatal
-- collision if you drive after drinking.
Please don’t drink and drive
or ride with a driver
who has been drinking. Ride home in a cab; or
if you’re with a group, designate a driver who
will not drink.
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.

Downloaded from www.Manualslib.com manuals search engine Braking
Braking 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 ( 100 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 braking. Some people drive
in 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 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.

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.

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.

Downloaded from www.Manualslib.com manuals search engine ASR (Acceleration Slip Regulation) System
(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 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.

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.
