Care of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes or a damaged
mechanism. Cassette tapes should
be stored in their
cases away from contaminants, direct sunlight and
extreme heat. If they aren’t, they may not operate
properly or may cause failure
of the tape player.
Your tape player should be cleaned regularly after every
50 hours of use. Your radio may display CLN to indicate
that you have used your tape player for
50 hours without
resetting the tape clean timer,
If this message appears
on the display, your cassette tape player needs to be
cleaned. It will still play tapes, but you should clean it as
soon as possible to prevent damage to your tapes and
player. If you notice a reduction in sound quality, try a
known good cassette to see if it is the tape or the tape
player at fault. If this other cassette has no improvement
in sound quality, clean the tape player.
Cleaning may be done with a scrubbing action,
non-abrasive cleaning cassette with pads which scrub
the tape head as the hubs
of the cleaner cassette turn. It
is normal for the cassette to eject while cleaning because
your unit is equipped with a cut tape feature. To
temporarily override this feature for vehicles with
Automatic Tone Control (for one insertion), turn on the
ignition then turn the radio off and press and hold TAPE AUX until the tape symbol
flashes on the display, then
insert the cassette again. For vehicles without Automatic
Tone Control, press both SEEK arrows within five
seconds
of inserting the cassette with the ignition and
radio
off. Insert the cassette at least three times to ensure
thorough cleaning.
A scrubbing action cleaning cassette
is available through your GM dealership.
You may also choose a non-scrubbing action, wet-type
cleaner which uses a cassette with a fabric belt to clean
the tape head. This type of cleaning cassette will not
eject. It may not clean as thoroughly as the scrubbing
type cleaner.
The cassette tape player is able to detect a broken tape.
Some cleaning cassettes may appear as a broken tape.
If
the cleaning cassette is ejected immediately from the
tape player, follow these steps:
1. Turn the radio off.
2. Turn the ignition on.
3. Press and hold the TAPE-AUX button until the tape
symbol flashes.
4. Insert the cleaning cassette and the radio will turn on
in cassette mode.
5. Eject the tape after the tape player has been cleaned.

When the cleaning cassette has been ejected, the broken
tape detection feature is active again.
After you clean the player, press and hold EJECT for
five seconds to reset the CLN indicator. The radio will
display
--- to show the indicator was reset.
Cassettes are subject to wear and
the sound quality
may degrade over time. Always make sure the cassette
tape is in good condition before you have your tape
player serviced.
Care of Your Compact Discs
Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust. If the surface of a disc is soiled, dampen
a
clean, soft cloth in a mild, neutral detergent solution and
clean it, wiping from the center to the edge.
Be sure never to touch the signal surface when handling
discs. Pick up discs by grasping the outer edges or the
edge of the hole and the outer edge.
Fixed Mast Antenna
The fixed mast antenna can withstand most car washes
without being damaged. If the mast should ever become
slightly bent, you can straighten it out
by hand. If the
mast is badly bent, as it might be by vandals, you should
replace it.
Check every once in
a while to be sure the mast is still
tightened to the cowl.

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 anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent a braking skid.
When you start your engine and 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. This is normal.
ANTI -
LOCK
If there’s a problem with the
anti-lock brake system, this
warning light will stay on.
See “Anti-Lock Brake
System Warning Light” in
the Index.

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.
Off-Road Recovery
You may find sometime that your right wheels have
dropped
off the edge of a road onto the shoulder while
you’re driving.
If the level of the shoulder is only slightly below the
pavement, recovery should be fairly easy. Ease
off the
accelerator and then,
if there is nothing in the way, steer so
that your vehicle straddles the edge of the pavement. You
can
turn the steering wheel up to one-quarter turn until the
right front tire contacts the pavement edge. Then
turn your
steering wheel to go straight down the roadway.

When you drive over obstacles or rough terrain, keep a
firm grip
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 wheels 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 this is certainly true for off-road driving. At
the very time you need special alertness and driving
skills, your reflexes, perceptions and judgment 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.
Driving on Off-Road Hills
Off-road driving often takes you up, down or across a
hill. Driving safely on hills requires good judgment and
an understanding of what your vehicle can and can’t
do.
There are some hills that simply can’t be driven, no
matter how well built the vehicle.
Many hills are simply too steep for any vehicle. If
you drive up them, you will stall. If you drive
down them, you can’t control your speed. If you
drive across them, you will roll over. You could be
seriously injured or killed. If you have any doubt
about the steepness, don’t drive the hill.

Driving Downhill
When off-roading takes you downhill, you’ll want to
consider
a number of things:
0 How steep is the downhill? Will I be able to maintain
vehicle control?
0 What’s the surface like? Smooth? Rough? Slippery?
Hard-packed dirt? Gravel?
Are there hidden surface obstacles? Ruts? Logs?
Boulders?
0 What’s at the bottom of the hill? Is there a hidden
creek bank or even a river bottom with large rocks?
If you decide you can go down a
hill safely, then try to
keep your vehicle headed straight down, and use a low
gear. This way, engine drag can help your brakes and
they won’t have to do all the work. Descend slowly,
keeping your vehicle under control at all times.
I
A C UTT3N:
I
Heavy braking when going down a hill can cause
your brakes to overheat and fade. This could cause loss
of control and a serious accident.
Apply the brakes lightly when descending a
hill and use a low gear to keep vehicle speed
under control.

Stalling on an Incline
If your vehicle stalls when you’re crossing an incline, be
sure you (and your passengers) get out on the uphill
side, even if the door there is harder to open. If you get
out
on the downhill side and the vehicle starts to roll
over, you’ll be right in its path.
If you have to walk down the slope, stay out of the path
the vehicle will take
if it does roll over.
Getting out on the downhill (low) side of a vehicle
stopped across an incline
is dangerous. If the
vehicle rolls over, you could be crushed or killed.
Always get out on the uphill (high) side
of the
vehicle and stay well clear
of the rollover path.
Driving in Mud, Sand, Snow or Ice
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.
4-26
ProCarManuals.com

Hard packed snow and ice offer the worst tire traction.
On these 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. through.
Also, water that deep can damage your axle
and other vehicle parts.
If the water isn’t too deep, then drive through it slowly. At
fast speeds, water splashes on your ignition system and
your vehicle can stall. Stalling can
also occur if you get
your tailpipe under water. And, as long as your tailpipe
is
under water, you’ll never be able to start your engine.
When you
go through water, remember that when your
brakes get wet, it may take you longer to stop.
I
Driving on frozen lakes, ponds or rivers can be
dangerous. Underwater springs, currents under
the ice, or sudden thaws can weaken the ice. Your
vehicle could fall through the ice and you and
your passengers could drown. Drive your vehicle
on safe surfaces only.
Driving in Water
Light rain causes no special off-road driving problems.
But heavy rain can mean flash flooding, and flood
waters demand extreme caution.
Find out how deep the water is before you drive through
it. If it’s deep enough to cover your wheel hubs, axles or
exhaust pipe, don’t
try it -- you probably won’t get
A CAUTION:
Driving through rushing water can be dangerous.
Deep water can sweep your vehicle downstream
and you and your passengers could drown.
If it’s
only shallow water, it can still wash away the
ground from under your tires, and you could lose
traction and roll the vehicle over. Don’t drive
through rushing water.
See “Driving Through Water” in the Index for more
information on driving through water.

Drive defensively.
Don’t drink and drive.
Adjust your inside rearview mirror to reduce the
glare from headlamps behind you.
Since you can’t see as well,
you may need to slow
down and keep more space between you and
other vehicles.
Slow down, especially
on higher speed roads. Your
headlamps 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.
Night Vision
No one can see as well at night as in the daytime. But as
we get older these differences increase. A 50-year-old
driver may require at least twice as much light to see the
same thing at night as a 20-year-old.
What you do
in the daytime can also affect your night
vision. For example,
if you spend the day in bright
sunshine you are wise to wear sunglasses. Your eyes will
have less trouble adjusting
to night. But if you’re
driving, don’t wear sunglasses at night. They may cut down
on glare from
headlamps, but they also make a lot
of things invisible.
You can be temporarily blinded by approaching
headlamps. It can take a second or two, or even several
seconds, for your
eyes to readjust to the dark. When you
are faced with severe glare (as from a driver who
doesn’t lower the high beams, or a vehicle with
misaimed headlamps), slow down a little. Avoid staring
directly into the approaching headlamps.
Keep your windshield and all the glass on your vehicle
clean
-- inside and out. Glare at night is made much
worse by dirt on the glass. Even the inside of the glass
can build up a film caused by dust. Dirty glass makes
lights dazzle and flash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that your headlamps light up far less of a
roadway when you
are in a turn or curve. Keep your
eyes moving; that way, it’s easier to pick out dimly
lighted objects. Just as your headlamps should be
checked regularly for proper aim,
so should your eyes
be examined regularly. Some drivers suffer from night
blindness
-- the inability to see in dim light -- and aren’t
even aware
of it.
