Care of the CD and DVD Player

The use of CD or DVD lens cleaners for CDs or
DVDs are not advised, due to the risk of
contaminating the lens of the CD optics with
lubricants internal to the CD or DVD mechanism.

Fixed Mast Antenna

The fixed mast antenna can withstand most car
washes without being damaged. If the mast should
ever become slightly bent, straighten it out by
hand. If the mast is badly bent, replace it.
Check occasionally to make sure the mast is still
tightened.
XM™ Satellite Radio
Antenna System
The XM™ Satellite Radio antenna is located on
the roof of your vehicle. Keep this antenna clear of
snow and ice build up for clear radio reception.
If your vehicle has a sunroof, the performance of
the XM™ system may be affected if the sunroof
is open.
300
Loading items onto the roof of your vehicle can
interfere with the performance of the XM™ system.
Make sure the XM™ Satellite Radio antenna is
not obstructed.

Chime Level Adjustment

The radio is used to adjust the vehicle's chime
level. To change the volume level of the chime,
press and hold pushbutton 6 with the ignition
on and the radio power off. The volume level will
change from the normal level to loud, and
LOUD CHIME will appear on the radio display.
To change back to the default or normal setting,
press and hold pushbutton 6 again. The volume
level will change from the loud level to normal,
and NORMAL CHIME will appear on the
radio display. Removing the radio and not
replacing it with a factory radio or chime module
will disable vehicle chimes.
