Vehicle Damage Warnings
Also, in this book you will find these notices:
NOTICE:
These mean there is something that could damage
your vehicle.
In the notice area, we tell you about something that can
damage your vehicle. Many times, this damage would
not be covered by your warranty, and it could be costly.
But the notice will tell you what to do to help avoid
the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different
colors or in different words.
You'll also see warning labels on your vehicle.
They use the same words, CAUTION or NOTICE.

Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of your windows.

When you enter a vehicle in cold weather, turn the
fan knob all the way to the right for a few moments
before driving. This helps clear the intake ducts of
snow and moisture, and reduces the chance of
fogging the inside of your windows.

Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.

The use of non
-GM approved hood air deflectors
may adversely affect the performance of the heating
and air conditioning system.
Audio Systems
Your audio system has been designed to operate easily
and give years of listening pleasure. You will get the
most enjoyment out of it if you acquaint yourself with it
first. Find out what your audio system can do and how
to operate all of its controls to be sure you're getting the
most out of the advanced engineering that went into it.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, you can play your audio
system even after the ignition is turned off. See
ªRetained Accessory Powerº in the Index.
Setting the Clock
Press and hold HR until the correct hour appears on the
display. Press and hold MN until the correct minute
appears on the display. To display the clock with the
ignition off, press RECALL or HR/MN and the time
will be displayed for a few seconds. There is an initial
two
-second delay before the clock goes into the
time
-set mode.

3-12 AM-FM Stereo with Cassette
Tape Player (Bose

)
Included with this audio system are ten Bose
speakers,
an Acoustimass
bass module and a seven channel Bose
amplifier. See your dealer for details.
Playing the Radio
PWR (Power): Press this knob to turn the system on
and off.
VOL (Volume): Turn this knob clockwise to increase
volume. Turn it counterclockwise to decrease volume.
The knob is capable of being turned continuously.REAR DSPL (Display): When the main radio is turned
on, press this button to see the rear seat audio settings
displayed on the main radio. Press it again to turn the
rear seat audio display off. See ªRear Seat Audioº in the
Index for more information.
RECALL: Press this button to display the station being
played or to display the clock. Clock display is available
with the ignition turned off.
SCV (Speed
-Compensated Volume): With SCV, your
audio system adjusts automatically to make up for road
and wind noise as you drive. Set the volume at the
desired level. Turn the control ring behind the upper
knob clockwise to adjust the SCV. Each notch on the
control ring allows for more volume compensation at
faster vehicle speeds. Then, as you drive, SCV
automatically increases the volume, as necessary, to
overcome noise at any speed. The volume level should
always sound the same to you as you drive. If you don't
want to use SCV, turn the control ring counterclockwise.

3-16
Cassette Tape Messages
CLN (Clean): If this message appears on the display,
the 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 the tapes and player. See ªCare of
Your Cassette Tape Playerº in the Index.
CD Adapter Kits
It is possible to use a portable CD player adapter kit
with your cassette tape player after activating the bypass
feature on your tape player.
To activate the bypass feature, use the following steps:
1. Turn the ignition to RUN or ACCESSORY.
2. Turn the radio off.
3. Press and hold the CD TAPE button for five seconds.
The tape symbol on the display will flash for
two seconds, indicating the feature is active.
4. Insert the adapter into the cassette slot. It will power
up the radio and begin playing.
This override routine will remain active until EJECT
is pressed.Rear Seat Audio (RSA)
This feature allows rear seat passengers to listen to and
control any of the music sources (AM
-FM, cassette
tapes and CDs) through the Rear Seat Audio (RSA)
controller. However, the rear seat passengers can only
control the music sources that the front seat passengers
are not listening to. For example, rear seat passengers
may listen to a cassette tape through headphones while
the driver listens to the radio through the front speakers.
The rear seat passengers have control of the volume for
each set of headphones. Be aware that the front seat
audio controls always have priority over the RSA
controls. If the front seat passengers switch the source
for the main radio to a remote source, the RSA will play
the same remote source. The rear speakers will be muted
when the RSA power is turned on. You may operate the
RSA functions even when the main radio is off.
Primary Radio Controls
The following function is controlled by the knob on the
main radio:
PWR (Power): Push this knob twice to turn RSA off.

audio functions even when the primary radio power

Turn the knob clockwise to increase volume and
counterclockwise to decrease volume. Push the knob
back into its stored position when you're not using it.

plugged into the lower jack.
AM FM: Press this button to switch between AM, FM1
and FM2. If the front passengers are already listening to
AM FM, the RSA controller will not switch between the
bands and cannot change the frequency.
Press AM FM to return to listening to the radio when a
cassette tape or CD is playing. The inactive tape or CD
will remain safely inside the radio for future listening.
