Care of Your CDs and DVDs
If playing recorded media such as a CD or DVD, the
sound quality may be reduced due to CD or DVD quality,
the method of recording, the quality of the music that has
been recorded, recording speed. Max media recording
speed, and the way the CD or DVD has been handled.
There may be an increase in skipping, difficulty in nding
tracks, and/or difficulty in loading and ejecting. If these
problems occur, check the bottom surface of the CD or
DVD. If the surface is damaged, such as cracked, broken,
or scratched, it will not play properly. If the surface is
soiled, see “Care of Your CDs and DVDs” in the Index of
the vehicle’s owner manual.
If there is no apparent damage, try a known good
CD or DVD.
Notice:If a label is added to a CD or DVD, or more
than one CD or DVD is inserted into the slot at a
time, or an attempt is made to play scratched
or damaged CDs or DVDs, the player could be
damaged. While using the CD or DVD player, use
only CDs or DVDs in good condition without
any label, load one CD or DVD at a time, and keep
the player and the loading slot free of foreign
materials, liquids, and debris.

If the system fails to turn on or activate, the StabiliTrak
light along with one of the following messages will
be displayed on the Driver Information Center (DIC):
TRACTION CONTROL OFF, SERVICE TRACTION
CONTROL, STABILITRAK OFF, SERVICE
STABILITRAK. If these DIC messages appear, make
sure the StabiliTrak system has not been turned
off using the StabiliTrak on/off button. Then turn the
steering wheel clockwise from the nine o’clock position
to the three o’clock position. If this clears the
message(s), the vehicle does not need servicing. If this
does not clear the message(s), then turn the vehicle
off, wait 15 seconds, and then turn it back on again to
reset the system. If any of these messages still
appear on the Driver Information Center (DIC), the
vehicle should be taken in for service. For more
information on the DIC messages, seeDriver
Information Center (DIC) on page 3-46.
The StabiliTrak light will
ash on the instrument
panel cluster when
the system is both on
and activated.
The system may be heard or felt while it is working;
this is normal.The traction control disable
button is located on the
instrument panel below the
climate controls.
The traction control part of StabiliTrak can be turned off
by pressing and releasing the StabiliTrak button if
both systems (traction control and StabiliTrak) were
previously on. To disable both traction control and
StabiliTrak, press and hold the button for ve seconds.
Traction control and StabiliTrak can be turned on by
pressing and releasing the StabiliTrak button if not
automatically shut off for any other reason.
When the TCS or StabiliTrak system is turned off, the
StabiliTrak light and the appropriate TCS off or
StabiliTrak off message will be displayed on the DIC to
warn the driver. The vehicle will still have brake-traction
control when traction control is off, but will not be
able to use the engine speed management system. See
“Traction Control Operation” next for more information.
When the traction control system has been turned
off, system noises may still be heard as a result of the
brake-traction control coming on.

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 or
snow, and you want to “rock” the vehicle to 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 5-30
Traction Control Operation
The traction control system is part of the StabiliTrak
system. Traction control limits wheel spin by reducing
engine power to the wheels (engine speed management)
and by applying brakes to each individual wheel
(brake-traction control) as necessary.
The traction control system is enabled automatically
when the vehicle is started. It will activate and the
StabiliTrak light will ash if it senses that any of the
wheels are spinning or beginning to lose traction while
driving. If traction control is turned off, only the
brake-traction control portion of traction control will
work. The engine speed management will be disabled.
In this mode, engine power is not reduced automatically
and the driven wheels can spin more freely. This can
cause the brake-traction control to activate constantly.Notice:If the wheel(s) of one axle is allowed to
spin excessively while the StabiliTrak, ABS
and brake warning lights and any relevant DIC
messages are displayed, the transfer case could be
damaged. The repairs would not be covered by
the vehicle warranty. Reduce engine power and do
not spin the wheel(s) excessively while these
lights and messages are displayed.
The traction control system may activate on dry or
rough roads or under conditions such as heavy
acceleration while turning or abrupt upshifts/downshifts
of the transmission. When this happens, a reduction
in acceleration may be noticed, or a noise or vibration
may be heard. This is normal.
If cruise control is being used when the system
activates, the StabiliTrak light will ash and cruise
control will automatically disengage. Cruise control may
be reengaged when road conditions allow. See
Cruise Control on page 3-11
StabiliTrak may also turn off automatically if it determines
that a problem exists with the system. If the problem does
not clear itself after restarting the vehicle, see your
dealer/retailer for service.
