3-30 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 dealer (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.
1. Turn the ignition to ON or ACC.
2. Turn the radio off.
3. Press and hold the TAPE AUX button for five
seconds. The tape symbol on the display will flash
for two seconds.
4. Insert the scrubbing action cleaning cassette.
5. Eject the cleaning cassette after the manufacturer's
recommended cleaning time.
When the cleaning cassette has been ejected, the cut tape
detection feature is active again.
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 on its own. A non
-scrubbing action cleaner may
not clean as thoroughly as the scrubbing type cleaner.
The use of a non
-scrubbing action, dry-type cleaning
cassette is not recommended.

3-32 Power Antenna Mast Care (Convertible)
Your power antenna will look its best and work well
if it's cleaned from time to time. To clean the
antenna mast:
1. Turn on the ignition and radio to raise the antenna.
2. Dampen a clean cloth with mineral spirits or
equivalent solvent.
3. Wipe the cloth over the mast sections, removing
any dirt.
4. Wipe dry with a clean cloth.
5. Make the antenna go up and down by turning the
radio or ignition off and on.
6. Repeat if necessary.
NOTICE:
Don't lubricate the power antenna. Lubrication
could damage it.
NOTICE:
Before entering an automatic car wash, turn off
your radio to make the power antenna go down.
This will prevent the mast from possibly getting
damaged. If the antenna does not go down when
you turn the radio off, it may be damaged or
need to be cleaned. In either case, lower the
antenna by hand by carefully pressing the
antenna down.
If the mast portion of your antenna is damaged, you can
replace it. See your dealer for a replacement kit and
follow the instructions in the kit.
Integrated Windshield and Rear Window
Antennas (Coupe)
The antennas in your vehicle are located in the
windshield and the rear window. The connectors are at
the top of the windshield and the top of the rear window
above the rear window defogger.

4-12 Competitive Driving Mode
The driver can select the optional handling mode by
pressing the ACTIVE HANDLING button on the
console for more than five seconds. Competitive
Driving mode allows the driver to have full control of
the rear wheels while the Active Handling System helps
steer the vehicle by selective brake application. The
instrument cluster light will not be on. The Traction
Control System will not be operating. Adjust your
driving accordingly.
When you press the ACTIVE HANDLING button
again, or turn the ignition to ACC, the Active Handling
and Traction Control Systems will be on. The
TRAC/ACT HNDLG
-ON message will be displayed
temporarily in the DIC and a chime will be heard.
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.
Magnetic Speed Variable Assist Steering
Your vehicle is equipped with a steering system that
continuously adjusts the effort you feel when steering at
all vehicle speeds. It provides ease when parking yet a
firm, solid feel at highway speeds.
Steering Tips
Driving on Curves
It's important to take curves at a reasonable speed.
A lot of the ªdriver lost controlº accidents mentioned on
the news happen on curves. Here's why:
Experienced 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 your speed. While you're
in a curve, speed is the one factor you can control.

If you drive regularly in steep country, or if you're
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.

Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system and
transmission. These parts can work hard on
mountain roads.

Know how to go down hills. The most important
thing to know is this: let your engine do some of the
slowing down. Shift to a lower gear when you go
down a steep or long hill.
CAUTION:
If you don't shift down, your brakes 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. Shift down to let
your engine assist your brakes on a steep
downhill slope.
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 transmission, 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.

2. Get the vehicles close enough so that 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
transmission in PARK (P) or a manual transmission
in NEUTRAL before setting the parking brake.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or accessory plug. 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. Find the
positive (+) and negative (
-) terminals on each.
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.

6-16 When to Change Engine Oil
Your vehicle has a computer that lets you know when to
change your engine oil. This is not based on mileage,
but on engine revolutions and engine operating
temperature. When the computer has calculated that the
oil needs changing, the GM Oil Life System
will
indicate that a change is necessary. The mileage between
oil changes will vary depending on how you drive your
vehicle
-- usually between 3,000 miles (5 000 km) and
15,000 miles (25 000 km) since your last oil and filter
change. Under severe conditions, the system may
come on before 3,000 miles (5 000 km). Never drive
your vehicle more than 15,000 miles (25 000 km)
or 12 months (whichever occurs first) without an
oil change. Use engine oil meeting the GM
Standard GM4718M.
The system won't detect dust in the oil. So, if you drive
in a dusty area, be sure to change your oil and filter
every 3,000 miles (5 000 km) or sooner if the CHANGE
OIL SOON message appears. Remember to reset the
Engine Oil Life Monitor whenever the oil is changed.
How to Reset the Change Oil Soon Message
To reset the CHANGE OIL SOON message after an oil
change, do the following:
1. Turn the ignition to ON, with the engine off.
2. Press the TRIP button so the OIL LIFE percentage
is displayed.
3. Press RESET and hold for two seconds. OIL LIFE
REMAIN 100% will appear.
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 throw away clothing or
rags containing used engine oil. See the manufacturer's
warnings about the use and disposal of oil products.
Used oil can be a real threat to the environment. If you
change your own oil, be sure to drain all free
-flowing oil
from the filter before disposal. Don't ever dispose of oil
by putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used oil. If
you have a problem properly disposing of your used oil,
ask your dealer, a service station or a local recycling
center for help.

The plug has the following three separate wires:

The orange wire connects to battery power.

The yellow wire connects to ignition power.
(Power is only available when the ignition is in ON.)

The black wire connects to ground.
NOTICE:
When using the accessory power plug:

DO NOT splice wires directly into the
vehicle electrical wire harness. If done
incorrectly, splicing may cause damage to
your electrical system and would not be
covered by the vehicle's warranty.

The maximum load of any electrical
equipment should not exceed 15 amps.
NOTICE: (Continued)
NOTICE: (Continued)

Be sure to turn off any electrical equipment
when not in use. Leaving electrical
equipment on for extended periods of time
can drain your battery.

DO NOT use this plug if the electrical
equipment requires frequent connecting
and disconnecting. This may cause
excessive wear on the accessory power
plug and damage your electrical system
and the damage would not be covered by
your warranty.
Headlamps
The headlamp wiring is protected by a circuit breaker.
An electrical overload will cause the lamps to go on and
off, or in some cases to remain off. If this happens, have
your headlamp wiring checked right away.
