Check XM: If this message does

Consult with your dealer.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.

Adding non-dealer/non-retailer
accessories can affect the vehicle's
performance. SeeAccessories and
Modifications on page 10‑3.
StabiliTrak®System
The vehicle has an electronic
stability control system called
StabiliTrak. It is an advanced
computer controlled system that
assists the driver with directional
control of the vehicle in difficult
driving conditions.
StabiliTrak activates when the
computer senses a discrepancy
between the intended path and the
direction the vehicle is actually
traveling. StabiliTrak selectively
applies braking pressure at any one
of the vehicle's brakes to assist the
driver with keeping the vehicle on
the intended path.
When the vehicle is started and
begins to move, 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. The
system should initialize before the
vehicle reaches 32 km/h (20 mph).
In some cases, it may take
approximately two miles of driving
before the system initializes.
If cruise control is being used
when StabiliTrak activates, the
cruise control automatically
disengages. The cruise control
can be re-engaged when road
conditions allow. See
Cruise Control
on page 9‑46.
If there is a problem detected with
StabiliTrak, a SERVICE STAB SYS
message displays on the Driver
Information Center (DIC). See Ride
Control System Messages on
page 5‑25 for more information.
When this message is displayed,
the system is not working. Adjust
your driving accordingly. StabiliTrak and Traction Control
(TCS) come on automatically
whenever the vehicle is started
and the systems are reset with
each ignition cycle. However,
when the transfer case is placed
in Four-Wheel-Low mode,
StabiliTrak is automatically
disabled. See
Four-Wheel Drive on
page 10‑29 for more information.
It is recommended to leave the
system on for normal driving
conditions, but it may be necessary
to turn the TCS portion of the
system off if the vehicle is stuck in
sand, mud, ice, or snow, and it is
necessary to “rock”the vehicle to
attempt to free it. 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
drive wheels can spin more freely.

Headlamp Aiming
Headlamp aim has been preset at
the factory and should need no
further adjustment.
However, if the vehicle is damaged
in a crash, the headlamp aim may
be affected. Aim adjustment to
the low-beam headlamps may be
necessary if oncoming drivers flash
their high-beam headlamps at you
(for vertical aim).
If the headlamps need to be
re-aimed, it is recommended that
the vehicle be taken to the dealer
for service.

for more than a year. The engine oil
and filter must be changed at least
once a year and the oil life system
must be reset. Your trained dealer
technician can perform this work.

accidentally, service the vehicle
