AM Stereo
This means the Delco@ system can receive C-QUAM@ stereo broadca\
sts. Many AM stations around the country use C-QUAM@
to produce stereo,
though some do not. (C-QUAM@ is a registered trademark of Motorola, Inc.).
If your Delco@ system can get C-QUAM? your “STEREO” light will come on
when you’re receiving it.

If you keep pace with the traffic and alllow realieti~ following dbtances, ‘you
will eliminate a lot .of unnecessary braking.. That means - better brakin’g . and
longer brake life;
,* If your engine ever stops while- you’re driving, brake normally but don’t
pump your brakes. If you do, tht$ pedal may get harder to. .push down. If
your- engine stops, you will still have some power $rake, 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 vehicl’e has an ‘advanced electronic braking system that can help keep it
under Control.
When you turn your key on you m.ay .hear a momentary clicking ngise. , ,.
Here’s I how anti-lock .works. Let’s say the road is wet. You’re d.rivilng. sifely.
Suddenly an animal jumps out In frqnt of you.

As you brake, your computer keeps receiving updates on rear wheel spee\
d
and controls braking pressure accordingly.
CAUTION I
A
Anti-lock doesn’t change the time you need to get your foot up to I
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 suddenly
slows or stops. Always leave enough room up ahead to stop, even
though you have anti-lock brakes.
To Use 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, but this is normal. Let
anti-lock work for you, but remember: Your front 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 anti-lock braking when you
shift into four-wheel drive. But you will have regular braking. When you shift
back into two-wheel drive, you will have anti-lock again.

Rear Drum Brakes
If you have rear drum brakes, they don’t have the wear indicators, \
but if you
ever hear a rear brake rubbing noise, have the rear brake lining inspected.
Also, the rear brake drums should be removed and inspected each time\
the
tires are removed for rotation or changing. When you have the \
front brakes replaced, have the rear brakes inspected, too.
Brake linings should always be replaced as complete axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does not return to normal height, or if
there is a rapid increase in pedal travel. This could be a sign of brake
trouble.
Brake Adjusiment
Every time you make a brake stop, your disc brakes adjust for\
wear. If your
brake pedal goes down farther than normal, your rear drum brak\
es may need
adjustment. Adjust them by backing up and firmly applying the brakes a few
times.
Braking In Emergencies
At some time, nearly every driver gets into a situation that requires hard
braking. You have the rear wheel anti-lock braking system. Your front wheels
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 wheels stopped rolling. That could be off the \
road, into the
very thing you were trying to avoid, or into traffic.
So, use a “squeeze” braking technique. This will give you max\
imum 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 Sieerhg
If you lose power steering assist because the engine stops or \
the system
fails to function, you can steer but it will take much more effort.

Steering in Emergencies
There are times when steering can be more effective than braki\
ng. For example, you come over a hill and find a truck stopped in yo\
ur lane, or a
car suddenly pulls out from nowhere, or a child darts out fro\
m 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; ther\
e isn't room.
That's the time for evasive action-steering around the problem. \
Your vehicle can perform very well in emergencies like these. First \
apply your
brakes, but not enough to lock your front wheels. 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 yo\
u
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. You must then be prep\
ared to steer
back to your original lane and then brake to a controlled stop.
Depending on your speed, this can be rather violent for an un\
prepared driver.
This is one of the reasons driving experts recommend that you use your
safety belts and keep both hands on the steering wheel.
K2218
The fact that such emergency situations are always possible is \
a good reason
to practice defensive driving at
all times.

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: the rear wheel anti-lock braking system (RWAL) helps\
avoid only
a rear braking skid. In a braking skid (where the front wheels are no longer
rolling), release enough pressure on the brakes to get the front wheels rolling
again. This restores steering control. Push the brake pedal dow\
n steadily
when you have to stop suddenly.
As long as the front wheels are rolling, you
will have steering control. Steer the way you want to go.
Off-Road Driving with Your FourcWheel
Drive Vehicle
This off-road guide is for vehicles that have four-wheel drive. Also, see
“Anti-lock Brakes” in the Index.
If your vehicle doesn’t have four-wheel drive,
you shouldn’t drive off-road unless you’re on a level, so\
lid surface.
Off-road driving can be great fun. But it does have some defi\
nite hazards.
The greatest
of these is the terrain itself.
“Off-roading” means you’ve left the great North American\
road system behind.
Traffic lanes aren’t marked. Curves aren’t banked. There a\
re no road signs.
Surfaces can be slippery, rough, uphill
or downhill. In short, you’ve gone right
back
to nature.
Off-road driving involves some new skills. And that’s why it’s very important
that you read this guide. You’ll find many driving tips and suggestions. These
will help make your off-road driving safer and more enjoyable. \
Before You Go Off-Roading
There are some things to do before you go out. For example, be sure to
have all necessary maintenance and service work done. Be sure \
you read all
the information about your four-wheel drive vehicle in this manual.
Is there
enough fuel?
Is the spare tire fully inflated? Are the fluid levels up where
they should be? What are the local laws that apply to off-roa\
ding where you’ll be driving?
If you don’t know, you should check with law enforcement people\

in the area. Will you be on someone’s private land?
If so, be sure to get the
necessary permission.
