radio. It works by using a secret code to disable all radio
functions whenever battery power is removed.
The THEFTLOCK feature for the radio may be used or
ignored. If ignored, the system plays normally and the
radio is not protected by the feature. If THEFTLOCK is
activated, your radio will not operate if stolen.

Understanding Radio Reception
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble to reduce this noise if you ever get it.

3-23 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.
The recommended cleaning method for your cassette
tape player is the use of a scrubbing action,
non
-abrasive cleaning cassette with pads which scrub
the tape head as the hubs of the cleaner cassette turn.
The recommended cleaning cassette is available through
your dealership (GM Part No. 12344789).When using a scrubbing action, non
-abrasive cleaning
cassette, it is normal for the cassette to eject because
your unit is equipped with a cut tape detection feature
and a cleaning cassette may appear as a broken tape. To
prevent the cleaning cassette from being ejected, use the
following steps.
If your vehicle is equipped with the AM
-FM Stereo with
Cassette Tape Player:
1. Turn the ignition to RUN or ACCESSORY.
2. Turn the radio on.
3. Insert the scrubbing action cleaning cassette.
4. Within five seconds, press and hold the REV and
FWD buttons at the same time for three seconds. The
tape symbol on the display will flash, showing that
the cut tape detection feature is no longer active.
5. Eject the cleaning cassette after the manufacturer's
recommended cleaning time.
If your vehicle is equipped with the AM
-FM Stereo with
Cassette Tape Player and Automatic Tone Control:
1. Turn the ignition to RUN or ACCESSORY.
2. Turn the radio off.

CAUTION:
Coasting downhill in NEUTRAL (N) or with the
ignition off is dangerous. Your brakes will have to
do all the work of slowing down. They could get so
hot that they wouldn't work well. You would then
have poor braking or even none going down a hill.
You could crash. Always have your engine running
and your vehicle in gear when you go downhill.

Know how to go uphill. You may want to shift down
to a lower gear. The lower gears help cool your engine
and transaxle, and you can climb the hill better.

Stay in your own lane when driving on two
-lane
roads in hills or mountains. Don't swing wide or cut
across the center of the road. Drive at speeds that let
you stay in your own lane.

As you go over the top of a hill, be alert. There could be
something in your lane, like a stalled car or an accident.

You may see highway signs on mountains that warn of
special problems. Examples are long grades, passing or
no
-passing zones, a falling rocks area or winding
roads. Be alert to these and take appropriate action.
Winter Driving
Here are some tips for winter driving:

Have your vehicle in good shape for winter.

You may want to put winter emergency supplies in
your trunk.

4-30 Towing Your Vehicle from the Front 3-Speed
Automatic Transaxle (With a Dolly)
Follow these steps:
1. Put the front wheels on a dolly.
2. Set the parking brake.
3. Open the fuse panel on the driver's side of the
instrument panel. Remove the fuse labeled
CLS/PCM. This will keep your battery from draining
while towing. See ªFuses and Circuit Breakersº in
the Index.4. Turn the ignition key to OFF to unlock the steering
wheel. See ºIgnition Positionsº in the Index.
5. Clamp the steering wheel in a straight
-ahead position
with a clamping device designed for towing.
6. Release the parking brake.
When you are finished towing, make sure you replace
the CLS/PCM fuse in the instrument panel fuse block.
Towing Your Vehicle From the Front
4-Speed Automatic and 5-Speed Manual
Transaxles (Without a Dolly)
You may tow your vehicle with all four wheels on the
ground for unlimited miles if you have a four
-speed
automatic or a five
-speed manual transaxle. If your
vehicle has a three
-speed automatic transaxle, it may not
be towed in this manner. To tow a vehicle with a
four
-speed automatic or a five-speed manual transaxle,
follow these steps:

4-31
1. Set the parking brake.
2. Open the fuse panel on the driver's side of the
instrument panel. Remove the fuse labeled
CLS/PCM. This will keep your battery from draining
while towing. See ªFuses and Circuit Breakersº in
the Index.3. Turn the ignition key to OFF to unlock the
steering wheel.
4. Shift your transaxle to NEUTRAL (N).
5. Release the parking brake.
When you are finished towing, make sure you replace
the CLS/PCM fuse in the instrument panel fuse block.
NOTICE:
Make sure that the towing speed does not exceed
65 mph (110 km/h), or your vehicle could be
badly damaged.

2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren't touching
each other. If they are, it could cause a ground
connection you don't want. You wouldn't be able to
start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved
in the jump start procedure. Put an automatic
transaxle in PARK (P) or a manual transaxle in
NEUTRAL (N) before setting the parking brake.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter. Turn off all lamps that aren't needed as well
as radios. This will avoid sparks and help save both
batteries. In addition, it could save your radio.
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn't be covered by
your warranty.
4. Open the hoods and locate the batteries.
CAUTION:
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools away from any underhood
electric fan.
5. Find the positive (+) and negative (-) terminals on
each battery.
