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.
Anti-Lock Brakes (ABS)
Your vehicle has an advanced electronic braking system that can help\
you
keep it under control.
If your vehicle has an anti-lock brake system warning light on th\
e
instrument panel, it has four-wheel anti-lock brakes. Otherwise, it has
rear-wheel anti-lock brakes. When you start a vehicle that has \
four-wheel anti-lock brakes 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. Y\
ou’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. With four-wheel
anti-lock:
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. The
four-wheel anti-lock system can change the brake pressure faster\
than any

Downloaded from www.Manualslib.com manuals search engine driver could. With rear-wheel anti-lock: If one of the rear wheels is about
to stop rolling, the computer will work the brakes at the rear wheels. The
computer is programmed to make the most of available tire and road
conditions.
As you brake, your 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 sudden\
ly slows or
stops. Always leave enough room up ahead to stop, even though you have
anti-lock brakes.
To Use Four-wheel Anti-Lock
Don’t pump the brakes. Just hold the brake pedal down and let anti-lock
work for you.
You may feel the brakes vibrate. or you may notice some
noise, but this is
1 mal.
To Use Rear-Wheel Anti-Lock
Use rear-wheel anti-lock like regular brakes. You may feel the brakes
vibrate, or you may notice some noise outside your vehicle, bu\
t
this is
normal. Let anti-lock work for you, but remember: Your Eront wheels can
still stop rolling. If that happens, release enough pressure on the brakes to
get the wheels rolling again
so that you can steer.
With the four-wheel drive option, you won’t have rear-wheel anti-lock
braking when you shift into four-wheel drive. But you will hav\
e regular
braking. When you shift back into two-wheel drive, you will ha\
ve rear-wheel anti-lock again.

Braking in Emergencies
At some time, nearly every driver gets into a situation that \
requires hard
braking.
The four-wheel anti-lock system lets you steer and brake at the same time.
If you have the rear-wheel anti-lock braking system, your front wh\
eels can
stop rolling when you brake very hard. Once they do, the vehicle can’t
respond to your steering. Momentum will carry it in whatever direction it
was headed when the front wheels stopped rolling. That could b\
e off the
road, into the very thing you were trying to avoid, or into traffic.
So, unless you have four-wheel anti-lock, use a “squeeze” braking
technique. This will give you maximum braking while maintaining \
steering
control. You do this by pushing on the brake pedal with steadily increasing
pressure. When you do, it will help maintain steering control. \
In many
emergencies, steering can help you more than even the very best braking.
Steering
Power Steering
If you lose power steering assist because the engine stops or the system is
not functioning, you can steer but it will take much more effort.
Steering Tips
Driving on Curves
It’s important to take eurves at a reasonable speed.
A lot of the “drrver lost control” accidents mentit- ~~- -- - -~ -1-3 news happen
on curves. Here’s why:
bxperienced 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 you\
r
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 apply
the brakes. Both control systems
- steering and braking - have to do their
work where the tires meet the road. Unless you have four-wheel\
anti-lock
brakes, adding the hard braking can demand too much of those places. You
can lose control.

ve 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 conditi\
ons, and by
not “overdriving” those conditions. But skids are always p\
ossible.
The three types of skids correspond to your Vehicle’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
comering force. And in the acceleration skid too much throttle causes t\
he
driving wheels to spin.
A cornering skid and an acceleration skid are 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.

log, hole, rut, or bump can startle you
if you’re not prepared for them. Often
these obstacles are hidden by grass, bushes, snow or even the rise and fall of
the terrain itself. Here are some things to consider:
Is the path ahead clear?
Will the surface texture change abruptly up ahead?
Does the travel take you uphill or downhill? (There’s more \
discussion
of these subjects later.)
Will you have to stop suddenly or change direction quickly?
When you drive over obstacles or rough terrain, keep a firm g\
rip on the steering wheel. Ruts, troughs, or other surface features can jerk the wheel
out
of your hands if you’re not prepared.
When you drive over bumps, rocks, or other obstacles, your whe\
els can leave the ground.
If this happens, even with one or two wheels, you can’t
control the vehicle as well or at all.
Because you will be
on an unpaved surface, it’s especially important to
avoid sudden acceleration, sudden turns,
or sudden braking.
In a way, off-road driving requires a different kind
of alertness from driving
on paved roads and highways. There are no road signs, posted \
speed limits
or signal lights. You have to use your own good judgment about what is safe
and what isn’t.
Drinking and driving can be very dangerous on any road. And t\
his is
certainly true for off-road driving. At the very time you need special
alertness and driving skills, your reflexes, perceptions and jud\
gment can be
affected by even a small amount of alcohol. You could have a serious
- or
even fatal
- accident if you drink and drive or ride with a driver who has
been drinking. (See “Drunken Driving” in the Index.)

NOTI.CE:
Pulling a trailer improperly can damage your vehicle and result\

in
costly repairs not coveredby your warranty. To pull a trailer
correctIy, follow the advice
in this section, and see your dealer
for important information about towing a trailer with your
vehicle.
Every vehicle is ready for some trailer towing. If it was built with trailering
options, as many are, it’s ready for heavier trailers. But trailering is different
than just driving your vehicle by itself. Trailering means changes in
handling, durability, and fuel economy. Successful, safe trailering takes
correct equipment, and it has to be used properly.
That’s the reason for
this section. In it are many time-tested, important
trailering tips and safety rules. Many
of these are important for your safety
and that of your passengers.
So please read this section carefully before you
pull a trailer.
If You Do Decide To Pull A Trailer
If you do, here qre some important points.
There are many different laws having to do with trailering. Ma\
ke sure
your rig will be legal, not only where you live but also whe\
re you’ll be driving.
A good source for this information can be state or provincial
police.
Consider using a sway control if your trailer will weigh 2,000 pounds
(900 kg) or less. You should always use a sway control if your trailer
will weigh more than
2,000 pounds (900 kg).

you check your electricql connection at the same time.
During your trip, check occasionally to be sure that the load \
is secure, and
that the lights and any trailer brakes
are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as you would when
driving your vehicle without a trailer. This can help you avoid situations \
that
require heavy braking apd sudden turns.
Passing
You’ll need more passing distance up ahead when you’re to\
wing a trailer.
And, because you’re a good deal longer, you’ll need to g\
o much farther
beyond the passed vehicle before you can return to your lane. \
Backing Up
Hold the bottom of the steering wheel with one hand. Then, to move the
trailer to the left, just move that hand to the left. To move the trailer to the
right, move your hand to the right. Always back up slowly and\
, if possible,
have someone guide you.
Making Turns
When you’re turning with a trailer, make wider turns than n\
ormal. Do this
so your trailer won’t strike soft shoulders, curbs, road signs, \
trees, or other
objects. Avoid jerky or sudden maneuvers. Signal well in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have a different \
turn signal
flasher and extra wiring. The green arrows on your instrument panel wi\
ll
flash whenever you signal a turn or lane change. Properly hooked up, the
trailer lights will also flash, telling other drivers you’re \
about
to turn,
change lanes or stop.
When towing a trailer, the green arrows on your instrument pan\
el will flash
€or
turns even if the bulbs on the trailer are burned out. Thus, you may think
drivers behind you are seeing your signal when they are not. It’s importan\
t
to check occasionally to be sure the trailer bulbs are still \
working.

Don’t add anything to your oil. Your GM dealer is ready to advise if you
think something should be added.
When to Change Engine Oil
See if any one of these is true for you:
Most trips are less than 4 miles (6 km).
0 It’s below freezing outside and most trips are less than 10 miles (16
km).
The engine is at low speed most of the time (as in door-to-door
delivery, or in stop-and-go traffic).
You tow a trailer often.
Most trips are through dusty places.
0 The vehicle is frequently operated off-road.
If any one of these is true for your vehicle, then you need to change your oil
andfilter every 3,000 miles (5 000 km) or 3 months - whichever comes
first.
If none of them is true, change the oil every
7,500 miles (12 500 km) or 12
months - whichever comes first. Change the filter at the first oil change
and at every other oil change after that.
Four-wheel Drive Remote Oil Filter
If your vehicle has four-wheel drive, you will have a remote oil filter
located under the radiator support. There is a special access \
door in the
vehicle body skirt shield.
Engine Coolant Heater (Engine Block Heater)
An engine coolant heater can be a big help if you have to park outside in
very cold weather,
0 “F (-1 8 O C) or colder. If your vehicle has this option,
see “Engine Coolant Heater
” in the Index.
What to Do with Used Oil
Did you know that used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer? Don’t let used oil stay
on your skin for very long. Clean your skin and nails with soap and water,
or a good hand cleaner. Wash or properly throw away clothing or rags
containing wed engine oil. (See the manufacturer’s warnings about the use
and disposal of oil products.)
