Your vehicle is equipped with six Bose® amplified speakers. 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 to increase or to decrease the volume.

RECALL: Press this button to switch the display between the radio station frequency and the time. When the ignition is off, press this knob to display the time.

SCV (Speed-Compensated Volume): With SCV, the 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 power knob clockwise to increase 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.To turn SCV off, turn the control ring all the way down.

Playing a Cassette Tape

The tape player is built to work best with tapes that are up to 30 to 45 minutes long on each side. Tapes longer than that are so thin they may not work well in this player. The longer side of the tape visible should face to the right. If you hear nothing or hear a garbled sound, it may not be in squarely. Press EJECT to remove the tape and start over.

If the ignition and radio are off, press the EJECT button or the RECALL button to insert and to begin play of a tape. If the ignition is on and the radio is off, the tape can be inserted and will begin playing. A tape symbol will appear on the display when a tape is inserted.

While the tape is playing, use the VOL, AUTO TONE, BAL, FADE, BASS, and TREB controls just as you do for the radio. Other controls may have different functions when a tape is inserted. The tape symbol and an arrow to show which side of the tape is playing will appear on the display.

Cassette tape adapter kits for portable CD players will work in the cassette tape player. See "CD Adapter Kits" later for more information.

The tape bias is set automatically when a metal or chrome tape is inserted.

If an error appears on the display, see "Cassette Tape Messages" later in this section.

Cassette Tape Messages

The cassette tape player is able to detect a tight or broken tape, and will eject the tape. The radio will go back to playing the last station selected. Try a known good cassette tape.

CLN (Clean): If this message appears on the display, the cassette tape player needs to be cleaned. It will still play tapes, but it should be cleaned as soon as possible to prevent damage to the tapes and player. See Care of the Cassette Tape Player .

If the cassette is not playing correctly, for any other reason, try a known good cassette.

If any error occurs repeatedly or if an error cannot be corrected, contact your dealer. If the radio displays an error message, write it down and provide it to your dealer when reporting the problem.

It is possible to use a portable CD player adapter kit with the cassette tape player after activating the bypass feature on the tape player.

To activate the bypass feature, use the following steps:

  1. Turn the ignition on.
  2. Turn the radio off.
  3. Press and hold the TAPE AUX button for five seconds. The tape symbol will flash for two seconds, indicating the feature is active.
