GMC Chevrolet SSR 2003 Owner's Manual page 175

If your vehicle is equipped with Bose
system allows you to choose from three different
equalization settings: normal, driver, and spacious.
These settings can be used while listening to the radio
or the CD player.
NORMAL: This setting provides the best overall vehicle
sound quality for all seating locations.
DRIVER: This setting gives the driver the best sound
quality.
SPACIOUS: This setting makes the listening space
seem larger.
The radio can save separate AUTO EQ settings for
each preset and source.
The Bose system will automatically adjust the
equalization to compensate for the change in acoustics
when the convertible top is down. The radio will mute
when the equalization switches just at the end of the top
down cycle and just at the beginning of the top up cycle.
