Rear Seat Audio (RSA)
This feature allows rear seat passengers to listen to any
of the sources: radio, CDs, or DVDs. However, the
rear seat passengers can only control the sources that
are not being listened by the front seat passengers.
For example, rear seat passengers can listen to
and control CDs or DVDs through the headphones
while the driver listens to the radio through the front
speakers. The rear seat passengers have control of the
volume for each set of headphones.
The front seat audio controls always have priority over
the RSA controls. If the front seat passengers switch
the source for the main radio to a remote source,
the RSA is not able to control the source. The rear seat
audio can be operated while the main radio is off.
P(Power):Press this button to turn the system on or
off. The rear speakers are muted when the power is
turned on.
u(Volume):Turn this knob to increase or to decrease
the volume. The left volume knob controls the left
wired headphones and the right volume knob controls
the right wired headphones.
SRCE (Source):Press this button to select a source:
radio, CD, or DVD. The inactive CD or DVD remains
inside the radio for future listening.

While a CD is playing, press the SEEK button to go to
the next track on the CD. This function is inactive if
the front seat passengers are listening to a CD.
While a CD is playing in the six-disc CD player, press and
hold the SEEK button for two seconds to go you to the
next CD, if multiple CDs are loaded. This function is
inactive if the front seat passengers are listening to a CD.Theft-Deterrent Feature
THEFTLOCK®is designed to discourage theft of your
vehicle’s radio. The feature works automatically by
learning a portion of the Vehicle Identi cation Number
(VIN). If the radio is moved to a different vehicle, it does
not operate and LOCKED displays.
When the radio and vehicle are turned off, the blinking
red light indicates that THEFTLOCK
®is armed.
With THEFTLOCK
®activated, the radio does not
operate if stolen.

Radio Reception
Frequency interference and static during normal radio
reception can occur if items such as cellphone chargers,
vehicle convenience accessories, and external
electronic devices are plugged into the accessory power
outlet. If there is interference or static, unplug the
item from the accessory power outlet.
AM
The range for most AM stations is greater than for
FM, especially at night. The longer range can cause
station frequencies to interfere with each other.
For better radio reception, most AM radio stations
boost the power levels during the day, and then reduce
these levels during the night. Static can also occur
when things like storms and power lines interfere with
radio reception. When this happens, try reducing
the treble on your radio.
FM Stereo
FM stereo gives the best sound, but FM signals reach
only about 10 to 40 miles (16 to 65 km). Tall buildings or
hills can interfere with FM signals, causing the sound
to fade in and out.
XM™ Satellite Radio Service
XM™ Satellite Radio Service gives digital radio
reception from coast-to-coast in the 48 contiguous
United States, and in Canada. Just as with FM,
tall buildings or hills can interfere with satellite radio
signals, causing the sound to fade in and out.
In addition, traveling or standing under heavy foliage,
bridges, garages, or tunnels may cause loss of the
XM™ signal for a period of time. The radio may display
NO SIGNAL to indicate interference.
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 the vehicle. Keep this antenna clear of snow and
ice build up for clear radio reception.
If the vehicle has a sunroof, the performance of the
XM™ system may be affected if the sunroof is open.
Loading items onto the roof of the 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.
