Section 2 Features and Controls

Sunroof
The vehicle may have a power sliding sunroof.
To open or close the sunroof, the ignition must be
on or Retained Accessory Power (RAP) must
be active. SeeRetained Accessory Power (RAP)
on page 137for more information.
The sunroof control is
located on the overhead
console. Press the
rear of the control to
open the sunroof to the
vent position, then
press the rear of the
control again to
express-open the
sunroof.
To close the sunroof, press and hold the front of
the control. The control must be held until the
glass stops moving, so that the sunroof will be fully
seated.The sunroof also has a roller sunscreen that can
be used to block the rays of the sun. The roller
sunscreen can be manually operated with
the sunroof in an open or closed position. To open
the sunscreen, press up to unlatch it and roll it
back. To close, pull it forward and latch it to
the close position.
If the battery has been recharged, disconnected,
or not working, the sunroof may need to be
reprogrammed. To do this, start the vehicle and
press forward on the sunroof control until it moves
to a fully closed position. This resets the sunroof
memory, enabling the sunroof to function properly.

Fixed Mast Antenna
The xed 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 to its base. If tightening is
required, tighten by hand, then with a wrench
one quarter turn.
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.
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 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 will appear on the radio display. Each
time the chime volume is changed, three
chimes will sound to indicate the new volume
selected. Removing the radio and not replacing it
with a factory radio or chime module will disable
vehicle chimes.
