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.

Radio Reception
Frequency interference and static can occur during
normal radio reception if items such as cell phone
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 the radio.
FM Stereo
FM signals only reach about 10 to 40 miles
(16 to 65 km). Although the radio has a built-in electronic
circuit that automatically works to reduce interference,
some static can occur, especially around tall buildings
or hills, causing the sound to fade in and out.
3-110

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.
Cellular Phone Usage
Cellular phone usage may cause interference with the
vehicle’s radio. This interference may occur when making
or receiving phone calls, charging the phone’s battery,
or simply having the phone on. This interference causes
an increased level of static while listening to the radio.
If static is received while listening to the radio, unplug
the cellular phone and turn it off.
Fixed Mast Antenna
The xed mast antenna can withstand most car washes
without being damaged. If the mast becomes slightly
bent, straighten it out by hand. If the mast is badly bent,
replace it.
Occasionally check to make sure the antenna is
tightened to its base. If tightening is required, tighten
by hand until fully seated plus one quarter turn.
XM™ Satellite Radio Antenna
System
The XM Satellite Radio antenna is located on the roof of
the vehicle. Keep the antenna clear of obstructions for
clear radio reception.
If the vehicle has a sunroof, the performance of the XM
system may be affected if the sunroof is open.
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.

Using ABS
Do not pump the brakes. Just hold the brake pedal
down rmly and let antilock work. The brakes might
vibrate or some noise might be heard, but this is normal.
Braking in Emergencies
ABS allows the driver to steer and brake at the same
time. In many emergencies, steering can help more than
even the very best braking.
Brake Assist
This vehicle has a Brake Assist feature designed to
assist the driver in stopping or decreasing vehicle speed
in emergency driving conditions. This feature uses the
stability system hydraulic brake control module to
supplement the power brake system under conditions
where the driver has quickly and forcefully applied the
brake pedal in an attempt to quickly stop or slow down
the vehicle. The stability system hydraulic brake control
module increases brake pressure at each corner of the
vehicle until the ABS activates. Minor brake pedal
pulsations or pedal movement during this time is normal
and the driver should continue to apply the brake pedal
as the driving situation dictates The Brake Assist feature
will automatically disengage when the brake pedal is
released or brake pedal pressure is quickly decreased.
StabiliTrak®System
The vehicle has the StabiliTrak system which combines
antilock brake, traction and stability control systems and
helps the driver maintain directional control of the vehicle
in most driving conditions.
Traction control activates when the controller senses
wheel spin. StabiliTrak will selectively apply the brakes
and reduce engine torque to help regain traction.
Stability control activates when the controller senses a
discrepancy between the intended path and the direction
the vehicle is travelling. StabiliTrak selectively applies
braking pressure at any one of the vehicle’s brakes to
help guide the vehicle in the intended direction.
When you rst start the vehicle and begin to drive away,
the system performs several diagnostic checks to insure
there are no problems. The system may be heard or felt
while it is working. This is normal and does not mean
there is a problem with the vehicle. If driving conditions
delay system initialization, the STABILITRAK NOT
READY message may be displayed on the Driver
Information Center (DIC). If this is the case, the
vehicle does not need servicing.
For more information on the stability messages, see
DIC Warnings and Messages on page 3-51.
4-6

When the StabiliTrak
system is both on and
actively controlling the
stability of the vehicle, the
StabiliTrak light will blink for
the duration of the event.
The system may be heard or felt while it is working.
This is normal.
The StabiliTrak disable
button is located on the
transmission shift handle.
The StabiliTrak system is automatically disabled in
4LO mode and cannot be turned on until the vehicle
is switched to 2HI, 4HI, or 4AWD.
The StabiliTrak system has three modes of operation:
STABILITRAK ON, TRACTION CONTROL OFF, and
STABILITRAK OFF.
STABILITRAK ON — The vehicle will default to
STABILITRAK ON every time the driver starts the
vehicle. The StabiliTrak light will be off and no DIC
messages will be displayed.TRACTION CONTROL OFF — The driver can modify
the engine speed management system by momentarily
pressing the StabiliTrak button on the transmission shift
handle. The StabiliTrak light will come on and TRACTION
CONTROL OFF will be displayed. For vehicles without
a DIC, the StabiliTrak indicator light will come on.
Momentarily pressing the StabiliTrak button again will
return the system to the STABILITRAK ON mode.
STABILITRAK OFF — The driver can turn off
StabiliTrak by pressing the StabiliTrak button for more
than ve seconds. The StabiliTrak light will come on
and STABILITRAK OFF will be displayed. For vehicles
without a DIC, the StabiliTrak indicator light will come on.
Momentarily pressing the StabiliTrak button again will
return the system to the STABILITRAK ON mode.
See StabiliTrak Off below for more information.
Traction Control Off
In this mode, stability control and brake-traction control
are functional. Engine speed management will be
modied and the driven wheels can spin more freely.
This can cause the brake-traction control to activate
more frequently. If the controller detects excessive wheel
spin in this mode, the StabiliTrak indicator light may
blink and the STABILITRAK ACTIVE message may be
displayed to warn the driver that damage may occur
to the transfer case.
4-7

StabiliTrak Off
In this mode, both stability control and part of the traction
control system are disabled. The vehicle will still have
brake-traction control, but will not be able to use the
engine speed management system. System noises may
be heard as a result of the brake-traction control coming
on. If the controller detects excessive wheel spin in this
mode, the StabiliTrak indicator light may blink and the
STABILITRAK ACTIVE message may be displayed
to warn the driver that damage may occur to the
transfer case.
It is recommended to leave the system on for normal
driving conditions, but it may be necessary to turn the
system off if the vehicle is stuck in sand, mud, ice orsnow, and you may want to “rock” the vehicle in an
attempt to free it. It may also be necessary to turn off the
system when driving in extreme off-road conditions where
high wheel spin is required. SeeIf Your Vehicle is Stuck
in Sand, Mud, Ice, or Snow on page 4-32for more
information.
When the transfer case is in 4LO, the stability system is
automatically disabled. The StabiliTrak light will come
on and the STABILITRAK OFF message will appear on
the DIC. The StabiliTrak system cannot be turned on
until the vehicle is switched to 2HI, 4HI, or 4AWD.
The following chart describes the StabiliTrak system
events and the corresponding messages and lights that
will be displayed on the instrument panel cluster.
