Your vehicle has an advanced electronic braking system that can help you
keep
it under control. When you start your vehicle and begin to drive away,
you may hear a momentary motor
or clicking noise. This is the ABS system
testing itself.
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 b\
rakes 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. You can steer around
the obstacle while braking hard.
As you brake, your computer keeps receiving updates on wheel speed and\
controls braking pressure accordingly.

When you drive in mud, snow or sand, your wheels won’t get good traction.
You can’t accelerate as quickly, turning
is more difficult, and you’ll need
longer braking distances.
It’s best to use a low gear when you’re in mud
- the deeper the mud, the
lower the gear. In really deep mud, the idea is to keep your vehicle moving
so you don’t get stuck.
When you drive on sand, you’ll sense a change in wheel traction. But it will
depend upon how loosely packed the sand is. On loosely packed sand (as on
beaches or sand dunes) your tires will tend to sink into the sand. This has an
effect on steering, accelerating, and braking. You may want to reduce
the air
pressure in your tires slightly when driving on sand. This will improve
traction.
Hard packed snow and ice offer the worst tire traction. On th\
ese surfaces,
it’s very easy to lose control. On wet ice, for example, the traction is
so poor
that you will have difficulty accelerating. And if you do get moving, poor
steering and difficult braking can cause you
to slide out of control.

Driving too fast through large water puddles or even going through some
car washes
can cause problems, too. The water may affect your brakes. Try
to avoid puddles. But if you can’t, try to slow down before you hit them.
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.
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.

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
GM dealerships
all across North America. They’ll be ready and willing to help if you need
it.
Here are some things you can check before a trip:
Windshield Washer Fluid: Is the reservoir full? Are all windows clean
inside and outside?
Wiper Blades: Are they in good shape?
0 Fuel, Engine Oil, Other Fluids: Have you checked all levels?
0 Lights: Are they all working? Are the lenses clean?
Tires: They are vitally important to a safe, trouble-free trip. Is the tread
good enough for long-distance driving? Are the tires all inflated to the
recommended pressure?
0 Weather Forecasts: What’s the weather outlook along your route?
Maps: Do you have up-to-date maps?
Should
you delay your trip a short time to avoid a major storm system?
Highway Hypnosis
Is there actually such a condition as “highway hypnosis”? Or is it just plain
falling asleep at the wheel? Call it highway hypnosis, lack of awareness, or
whatever.
There
is something about an easy stretch of road with the same scenery,
along with the hum of the tires on the road, the drone of the engine, and the
rush
of the wind against the vehicle that can make you sleepy. Don’t let it
happen
to you! If it does, your vehicle can leave the road in less than a
second,
and you could crash and be injured.
What can you
do about highway hypnosis? First, be aware that it can
happen.

This light on your instrument panel lets you know when your emission
system needs service. See “Malfunction Indicator Lamp” in the Index.
Tires
We don’t make tires. Your new vehicle comes with high quality tires made
by a leading tire manufacturer. These tires are warranted by the tire
manufacturers and their warranties
are delivered with every new vehicle. If
your spare tire is a different brand than your road tires, you will have a tire
warranty folder from each
of these manufacturers.
Inflation - lire Pressure
The Certificationire label which is on the driver’s door lock pillar, shows
the correct inflation pressures for your tires, when they’re cold. “Cold”
means your vehicle has been sitting for at least three hours or driven
no
more than a mile.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
Don’t let anyone tell you that underinflation or overinflation is
all right. It’s not.
If your tires don’t have enough air
(underinflation) you can get:
0 Too much flexing
0 Too much heat
0 Tire overloading
0 Bad wear
0 Bad handling
Bad fuel economy.
If your tires have too much air (overinflation), you can get:
Unusual wear
Bad handling
Rough ride
0 Needless damage from road hazards.
When to Check
Check your tires once a month or more. Also, check the tire pressure of the
spare tire.
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.

Tires should be inspected every 6,000 to 8,000 miles (10 000 to 13 000 km)
for any signs of unusual wear. If unusual wear is present, rotate your tires as
soon as possible and check wheel alignment. Also check for damaged tires
or wheels. See “When It’s Time for New Tires” and “Wheel Replacement”
later in this section for more information.
The purpose of regular rotation is to achieve more uniform wear for all tires
on the vehicle. The first rotation is the most important. See “Scheduled
Maintenance Services”
in the Index for scheduled rotation intervals.

rotating your
tires, always use one of the correct rotation
patterns shown here.
After the tires have been rotated, adjust the front and rear inflation pressure
as shown on the Certificatioflire label. Make certain that
all wheel nuts are
properly tightened. See “Wheel Nut Torque” in the Index.
