Setting the Tone (Bass/Treble) AUDIO: Press and release the AUDIO button until BASS, MID or TREB appears on the display. Press the knob above the AUDIO button to extend it, then turn the knob to increase or to decrease. If a station is weak or noisy, you may want to decrease the treble. Pressing and holding the AUDIO button for at least two seconds will return all tone settings, including balance and fade to flat. AUTO EQ (Automatic Equalizer): Press this button to choose bass and treble equalization settings designed for country, jazz, talk, pop, rock and classical program types. To return to the manual mode, press the AUTO EQ button until MANUAL appears on the display or adjust the bass and treble. Then you will be able to manually adjust the bass and treble using the AUDIO button. If your vehicle has the Bose® radio, press the AUTO EQ button to enhance the audio performance for different passengers in the vehicle. The setting last chosen will appear on the display when you first press AUTO EQ. Each time you press this button, another setting will appear on the display and AUTO EQ will switch to one of the preset settings listed. Your audio system allows you to choose from four different equalization settings: normal, driver, rear and spacious. These settings can be used while listening to the radio or the CD player. NORMAL: Provides the best overall vehicle sound quality for all seating locations. DRIVER: This setting gives the driver the best sound quality. REAR: This setting gives the rear seat passengers the best sound quality. SPACIOUS: This setting makes the listening space seem larger. The radio will save separate AUTO EQ settings for each preset and source. 3-61
