Speed Compensated Volume
(SCV):Radios with Speed
Compensated Volume (SCV)
automatically adjusts the radio
volume to compensate for road and
wind noise as the vehicle's speed
changes while driving, so that the
volume level stays consistent.
To activate SCV:
1. Set the radio volume to the desired level.
2. Press the MENU button to display the radio setup menu.
3. Press the softkey under the AUTO VOLUM (automatic
volume) tab on the radio display.
4. Press the softkey under the desired Speed Compensated
Volume setting (OFF, Low, Med,
or High) to select the level of
radio volume compensation.
The display times out after
approximately 10 seconds. Each
higher setting allows for more
radio volume compensation at
faster vehicle speeds. Noise Compensation
Technology:
Vehicles with the LTZ
package and a Bose Audio System
include the Bose AudioPilot
®noise
compensation technology. When
turned on, AudioPilot continuously
adjusts the audio system
equalization, to compensate for
background noise, so that music
always sounds the same at the set
volume level.
This feature is most effective at
lower radio volume settings where
background noise can affect how
well the music is heard. At higher
volume settings, where the music is
much louder than the background
noise, there might be little or no
adjustments by AudioPilot. To activate:
1. Set the radio volume to the
desired level.
2. Press the MENU button to display the radio setup menu.
3. Press the softkey under the AUTO VOLUM (automatic
volume) tab on the radio display.
4. Press the softkey under the ON tab. The display times out after
approximately 10 seconds.

AudioPilot, please visit

Audio Players
CD Player
Care of the CD Player
Do not add any label to a CD.
It could get caught in the CD. If a
CD is recorded on a personal
computer and a description label is
needed, try labeling the top of the
recorded CD with a marking pen.
The use of CD lens cleaners for
CDs is not advised, due to the risk
of contaminating the lens of the CD
optics with lubricants internal to the
CD player mechanism.
Notice:If a label is added to a
CD, or more than one CD is
inserted into the slot at a time,
or an attempt is made to play
scratched or damaged CDs, the
CD player could be damaged.
While using the CD player, use
only CDs in good condition
without any label, load one CD at
a time, and keep the CD player and the loading slot free of
foreign materials, liquids, and
debris.
If an error displays, see
“
Messages” later in this section.Care of CDs
If playing a CD-R, the sound quality
can be reduced due to CD-R or
CD-RW quality, the method of
recording, the quality of the music
that has been recorded, and the
way the CD-R or CD-RW has been
handled. Handle them carefully.
Store CD-R(s) or CD-RW(s) in their
original cases or other protective
cases and away from direct sunlight
and dust. The CD player scans the
bottom surface of the disc. If the
surface of a CD is damaged, such
as cracked, broken, or scratched,
the CD does not play properly or not
at all. Do not touch the bottom side
of a CD while handling it; this could
damage the surface. Pick up CDs
by grasping the outer edges or the
edge of the hole and the outer edge. If the surface of a CD is soiled,
clean it with a soft, lint free cloth or
dampen a clean, soft cloth in a mild,
neutral detergent solution mixed
with water. Make sure the wiping
process starts from the center to
the edge.Inserting a CD
Insert a CD partway into the slot,
label side up. The player pulls it in
and the CD should begin playing.
Ejecting a CD
ZEJECT:
Press and release to
eject the disc. Remove the CD
