Anti-Lock Brakes (corvr.)
And this light on the instrument panel
will go on when you start your vehicle.
When you start your vehicle and begin
to drive away you may hear a
momentary motor or clicking noise and
you may even notice that your brake
pedal moves a little while this is going
on. This
is the ABS system testing itself.
If you have your foot on the brake
pedal, this check won’t happen until the
vehicle goes about
4 mph (6 km/h) or
until you take your foot off the brake
pedal. After
an
ABS stop, you may hear a
clicking noise the next time the vehicle
goes about
4 mph (6 Wh).
If there’s a problem with the anti-lock
brake system, the anti-lock brake
system warning light will stay on or
flash. See the
Index under Anti-Lock
Brake System Warning
Light.

of you.
A computer senses that wheels are
slowing down. The computer separately
works 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.

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.
If you have the anti-lock braking
system, remember: It helps avoid only
the braking
skid. If you do not have
anti-lock, then
in a braking skid (where
the wheels are no longer rohg),
release enough pressure on the brakes
to get the wheels rolling again.
This
restores steering control. Push the
brake pedal down steadily when
you
have to stop suddenly. As long as the
wheels are rolling, you will have steering
control. Steer the way you want to
go.

Driving. at Might
Night driving is more dangerous than
day driving. One reason is that some
drivers are likely to be impaired-
by alcohol or drugs, with night vision
problems,
or by fatigue.
Here are some tips on night driving.
Drive defensively. Remember, this is
the most dangerous time.
Don’t drink and drive. (See the Index
under Drunken Driving for more on
this problem.)
Adjust your inside rearview mirror to
reduce the glare from headlights
behind you.
Since you can’t see as well, you may
need to slow
down and keep more
space between you
and other vehicles.
It’s hard to tell how fast the vehicle
ahead’is going just by looking at its
taillights.
Slow down, esp.ecially on higher
speed roads. Your headlights can light
up only so much road ahead.
In remote areas, watch for animals.
If you’re tired, pull off the road in a
safe place and rest.

Downloaded from www.Manualslib.com manuals search engine Hydroplaning
Hydroplaning is dangerous. So much
water can build up under your tires that
they can actually ride on the water. This
can happen if the road is wet enough
and you’re going fast enough. When
your vehicle is hydroplaning, it has little
or no contact with the road.
You might not be aware of
hydroplaning.
You could drive along for
some time without realizing your tires
aren’t in constant contact with the road.
You could find out the hard way: when
you have to slow, turn, move out to
pass--or if you get hit by
a gust of wind.
You could suddenly find yourself out of
control. Hydroplaning doesn’t happen often.
But
it can
if your tires haven’t much
tread or if the pressure in one or more is
low. It can happen if a lot of water is
standing on the road. If you can see
reflections from trees, telephone poles, or other vehicles, and raindrops
“dimple” the water’s surface, there
could be hydroplaning.
Hydroplaning usually happens at higher
speeds. There just isn’t a hard and fast
rule about hydroplaning. The best
advice is to slow down when it
is
raining, and be careful.
Some Other Rainy Weather Tips
Turn on your headlights-not just
your parking lights-to help make you
more visible to others.
Look for hard-to-see vehicles coming
from behind.
You may want to use
your headlights even in daytime if it’s
raining hard.
Besides slowing down, allow some
extra following distance. And be
especially careful when you pass
another vehicle. Allow yourself more
clear room ahead, and be prepared to
have your view restricted by road
spray. If the road spray is
so heavy
you are actually blinded, drop back.
Don’t pass until conditions improve.
Going more slowly is better than
having an accident.
Use your defogger if it helps.
Have good tires with proper tread
depth. (See the
Index under Tires.)

Driving a long Distance
Although most long trips today are
made on freeways, there are still many
made on regular highways.
Long-distance driving on freeways and
regular highways is the same in some
ways. The trip has to be planned and
the vehicle prepared, you drive at
higher-than-city speeds, and there are
longer turns behind the wheel. You’ll
enjoy your trip more if you and your
vehicle are in good shape. Here are
some tips for a successful long trip.

Before leaving on a Long Trip
Make sure you’re ready. Try to be well
rested. If you must start when you’re
not fresh-such as after a day’s work-
don’t plan to make too many miles that
first part
of the journey. Wear
comfortable clothing and shoes you can
easily drive in.
Is your vehicle ready for a long trip?
If
you keep it serviced and maintained, it’s
ready to go. If it needs service, have it
done before starting out. Of course,
you’ll find experienced and able service
experts in Chevrolet dealerships all
across North America. They’ll be ready
and willing to help
if you need it. Here

If you are parking on a hill and you
don’t shift your transaxle into
P (Park)
properly, the weight of the vehicle may
put too much force on the parking pawl
in the transaxle. You may find it
difficult
to pull the shift lever out of
P (Park). This is called “torque lock.”
To prevent torque lock, always be sure
to shift into
P (Park) properly before
you leave the driver’s seat. To find out
how, see the
Index under Shifting Into
P (Park).
When you are ready to drive, move the
shift lever out of
P (Park) before you
release the parking brake.
If torque lock does occur, you may need
to have another vehicle push yours a
little uphill to take some
of the pressure
from the transaxle, so you can pull the
shift lever out of
P (Park).
Winter Driving
Here are some tips for winter driving:
Have your Chevrolet in good shape
for winter. Be sure your engine
coolant mix
is correct.
Snow tires can help in loose snow,
but they may give you less traction on
ice than regular tires.
If you do not
expect to be driving in deep snow, but
may have to travel over ice, you may
not want to switch to snow tires at all.
You may want to put winter
emergency supplies in your trunk.
Include an ice scraper, a small brush
or broom, a supply of windshield
washer fluid, a rag, some winter outer
clothing, a small shovel, a flashlight,
a
red cloth, and a couple of reflective
warning triangles. And, if you will
be
driving under severe conditions,
include a small bag of sand, a piece
of
old carpet or a couple of burlap bags
to help provide traction. Be sure you
properly secure these items in your
vehicle.

Ifa Tire Goes Flat
It’s unusual for a tire to “blow OU~,)
while you’re driving, especially if you
maintain your tires properly. If air goes
out of a tire, it’s much more likely to
leak out slowly. But
if you should ever
have a “blowout,” here are a few tips
about what to expect and what to do:
If a front tire fails, the flat tire will
create a drag that pulls the vehicle
toward that side. Take your foot
off the
accelerator pedal and grip the steering
wheel firmly. Steer to maintain lane
position, then gently brake to a stop
well out of the traffic lane.
A rear blowout, particularly on a curve,
acts much like a
skid and may require
the same correction you’d use in a
skid.
In any rear blowout, remove your foot
from the accelerator pedal. Get the
vehicle under control by steering the
way you want the vehicle to go. It may
be very bumpy and noisy, but you can
still steer. Gently brake to a stop, well
off the road if possible.
If your tire goes flat, the next section
shows how
to use your jacking
equipment to change a
flat tire safely.

Downloaded from www.Manualslib.com manuals search engine Compact Spare Tire
Although the compact spare was fully
inflated when your vehicle was new, it
can lose air after a time. Check the
inflation pressure regularly. It should be
60 psi (420 kPa). The compact spare is
made to go up to
3,000 miles
(5 000 Inn), so you can finish your trip
and have
your full-size tire repaired or
replaced where
you want. Of course, it’s
best to replace your spare with a full-
size tire as soon as you can. Your spare
will last longer and be in good shape in
case you need it again. Your anti-lock
brake system warning light may come
on when you are driving with a compact
spare. See the
Index under Anti-Lock
Brake System Warning Light.
Don’t use your compact spare on some
other vehicle.
And don’t
mix your compact spare or
wheel with other wheels or tires. They
won’t fit. Keep your spare and its wheel
together.

Loading Your Vehicle
Two labels on your vehicle show how
much weight it may properly carry. The
Tire-Loading Information label found
on the inside of the trunk lid tells you
the proper size, speed rating and
recommended inflation pressures for
the tires on your vehicle. It also gives
you important information about the
number of people that can be in your
vehicle and the total weight that you
can carry. This weight is called the
Vehicle Capacity Weight and includes
the weight of all occupants, cargo, and
all nonfactory-installed options. The
other label is the Certification label,
on the rear edge
of the driver’s door. It
tells you the
gross weight capacity of
your vehicle, called the GVWR (Gross
Vehicle Weight Rating). The
GVWR
includes the weight of the vehicle, all
occupants, fuel and cargo. Never exceed
the GVWR for your vehicle, or the
Gross Axle Weight Rating
(GAWR) for
either the front or rear axle.
And,
if you do have a heavy load, you
should spread it out. Don’t carry more
than
167 lbs. (75 kg) in your trunk.

Downloaded from www.Manualslib.com manuals search engine When to Check:
Check your tires once a month or more.
Don't forget your compact spare tire. It
should be at
60 psi (420 kPa).
How to Check
Use a good quality pocket-type gage to
check tire pressure. Simply looking
at
the tires will not tell you the pressure,
especially
if you have radial tires-
which may look properly inflated even
if
they're underinflated.
If your tires have valve caps, be sure to
put them back on. They help prevent
leaks by keeping out dirt and moisture.
Tire Inspection and Rotation
To make your tires last longer, have
them inspected and rotated at the
mileages recommended in the
Maintenance Schedule. See the
Index
under Scheduled Maintenance
Services.
Use this rotation pattern.
Mer the tires have been rotated, adjust
the front and rear inflation pressure as
shown on the Tire-Loading Information
label. Make certain that
all wheel nuts
are properly tightened. See the
Index
under Wheel Nut Torque.
I
Rust or dirt on a wheel, or on
the parts to which it is
fastened, can make the wheel nuts
become loose after
a time. The
wheel could come
off and cause an
accident. When you change a
wheel, remove any rust
or dirt from
places where the wheel attaches to
the vehicle. In an emergency, you
can use a cloth
or a paper towel to
do this; but be sure to use a scraper
or wire brush later,
if you need to,
to get all the rust or dirt off. (See
the
Index under Changing a Flat
Tire.)
