Cruise Control
{CAUTION:
Cruise control can be dangerous where
you cannot drive safely at a steady speed.
So, do not use your cruise control on
winding roads or in heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
excessive wheel slip, and you could lose
control. Do not use cruise control on
slippery roads.
With cruise control, you can maintain a speed
of about 25 mph (40 km/h) or more without
keeping your foot on the accelerator. This can
really help on long trips. Cruise control does not
work at speeds below about 25 mph (40 km/h).
When you apply your brakes, cruise control
is turned off.If your vehicle has the StabiliTrak
®system and
begins to limit wheel spin while you are using cruise
control, the cruise control will automatically
disengage. SeeStabiliTrak
®System on page 330.
When road conditions allow you to safely use it
again, you may turn the cruise control back on.
The cruise control
buttons are located
on left side of the
steering wheel.
T(On/Off):This button can both activate and
turn off the system. The indicator light on the
button turns on when cruise control is on and turns
off when cruise control is off.

SERVICE TIRE MONITOR SYSTEM
If your vehicle has the Tire Pressure Monitor
(TPM) system, this message will display if a part
on the system is not working properly. If you
drive your vehicle while any of the four sensors
are missing or inoperable, the warning will
come on in about 20 minutes. A sensor would be
missing, for example, if you put different wheels
on your vehicle without transferring the sensors.
If the warning comes on and stays on, there
may be a problem with the TPM. See your dealer.
SERVICE TRACTION CONTROL
If your vehicle has StabiliTrak®, this message will
display when there is a problem with the traction
control system. When this message is displayed,
the system will not limit wheel spin. Adjust
your driving accordingly. See your dealer for
service. SeeStabiliTrak
®System on page 330
for more information.
STABILITRAK OFF
If your vehicle has StabiliTrak®, this message will
display when you turn off StabiliTrak®, or when
the stability control has been automatically
disabled. To limit wheel spin and realize the full
bene ts of the stability enhancement system, you
should normally leave StabiliTrak
®on. However,
you should turn StabiliTrak®off if your vehicle gets
stuck in sand, mud, ice, or snow and you want
to rock your vehicle to attempt to free it, or if you
are driving in extreme off-road conditions and
require more wheel spin. SeeIf Your Vehicle is
Stuck in Sand, Mud, Ice, or Snow on page 368.
To turn the StabiliTrak
®system on or off, see
StabiliTrak®System on page 330.
There are several conditions that can cause this
message to appear.
One condition is overheating, which could
occur if StabiliTrak®activates continuously
for an extended period of time.
The message will also be displayed if the
brake system warning light is on. See
Brake System Warning Light on page 235.
257
The message could be displayed if the
stability system takes longer than usual
to complete its diagnostic checks due to
driving conditions.
If an engine or vehicle related problem has
been detected and the vehicle needs
service, the message will appear. See your
dealer.
The message will also appear if the vehicle is
shifted into 4LO.
The message will turn off as soon as the
conditions that caused the message to be
displayed are no longer present.
TIGHTEN GAS CAP
If the vehicle’s fuel cap is not tightened properly,
this message may display along with the check
engine light on the instrument panel cluster.
SeeMalfunction Indicator Lamp on page 239.
Reinstall the fuel cap fully. SeeFilling the Tank on
page 401. The diagnostic system can determine
if the fuel cap has been left off or improperly
installed. A loose or missing fuel cap will allow fuel
to evaporate into the atmosphere. A few driving
trips with the cap properly installed should turn this
light and message off.
TIRE LEARNING ACTIVE
If your vehicle has a Tire Pressure Monitor (TPM)
system, this message will display when the
system is re-learning the tire positions on your
vehicle. SeeDIC Operation and Displays on
page 245for more information. The tire positions
must be re-learned after rotating the tires or
after replacing a tire or sensor. SeeTire Inspection
and Rotation on page 467,Tire Pressure Monitor
System on page 462, andIn ation - Tire
Pressure on page 460for more information.
TRACTION CONTROL OFF
If your vehicle has StabiliTrak®, this message will
display when the traction control system is
turned off. Adjust your driving accordingly. See
StabiliTrak
®System on page 330for more
information.

Audio System(s)
Determine which radio your vehicle has and then
read the pages following to familiarize yourself
with its features.
Driving without distraction is a necessity for a
safer driving experience. SeeDefensive Driving
on page 322. By taking a few moments to read
this manual and get familiar with your vehicle’s
audio system, you can use it with less effort,
as well as take advantage of its features. While
your vehicle is parked, set up your audio system
by presetting your favorite radio stations,
setting the tone, and adjusting the speakers.
Then, when driving conditions permit, you can tune
to your favorite stations using the presets and
steering wheel controls if the vehicle has them.{CAUTION:
This system provides you with a far greater
access to audio stations and song listings.
Giving extended attention to entertainment
tasks while driving can cause a crash and
you or others can be injured or killed.
Always keep your eyes on the road and
your mind on the drive — avoid engaging
in extended searching while driving.
Keeping your mind on the drive is important for
safe driving. For more information, seeDefensive
Driving on page 322.

Here are some ways in which you can help avoid
distraction while driving.
While your vehicle is parked:
Familiarize yourself with all of its controls.
Familiarize yourself with its operation.
Set up your audio system by presetting your
favorite radio stations, setting the tone, and
adjusting the speakers. Then, when driving
conditions permit, you can tune to your favorite
radio stations using the presets and steering
wheel controls if the vehicle has them.
Notice:Before adding any sound equipment
to your vehicle, such as an audio system,
CD player, CB radio, mobile telephone,
or two-way radio, make sure that it can be
added by checking with your dealer. Also,
check federal rules covering mobile radio and
telephone units. If sound equipment can be
added, it is very important to do it properly.
Added sound equipment may interfere with the
operation of your vehicle’s engine, radio, or
other systems, and even damage them.
Your vehicle’s systems may interfere with the
operation of sound equipment that has
been added.Notice:The chime signals related to safety
belts, parking brake, and other functions
of your vehicle operate through the
radio/entertainment system. If that equipment
is replaced or additional equipment is added
to your vehicle, the chimes may not work. Make
sure that replacement or additional equipment
is compatible with your vehicle before
installing it. SeeAccessories and Modifications
on page 396.
Your vehicle has a feature called Retained
Accessory Power (RAP). With RAP, the audio
system can be played even after the ignition
is turned off. SeeRetained Accessory Power
(RAP) on page 141for more information.

may be a receiver fault. Consult with your dealer.
Check XM Hardware failure If this message does not clear within a short period of time,
the receiver may have a fault. Consult with your dealer.
Navigation/Radio System
Your vehicle may have a navigation radio system.
The navigation system has built-in features
intended to minimize driver distraction. Technology
alone, no matter how advanced, can never
replace your own judgment. See the Navigation
System manual for some tips to help you
reduce distractions while driving.
Rear Seat Entertainment System
Your vehicle may have a DVD Rear Seat
Entertainment (RSE) system. The RSE system
works with the vehicle’s audio system. The
DVD player is part of the front radio. The RSE
system includes a radio with a DVD player, a video
display screen, audio/video jacks, two wireless
headphones, and a remote control. SeeRadio with
CD and DVD on page 273for more information
on the vehicle’s audio/DVD system.
303
Remember: ABS does not change the time you
need to get your foot up to the brake pedal
or always decrease stopping distance. If you get
too close to the vehicle in front of you, you will not
have time to apply your brakes if that vehicle
suddenly slows or stops. Always leave enough
room up ahead to stop, even though you
have ABS.
Using ABS
Do not pump the brakes. Just hold the brake
pedal down rmly and let anti-lock work for you.
You may feel the brakes vibrate, or you may notice
some noise, but this is normal.
Braking in Emergencies
With ABS, you can steer and brake at the same
time. In many emergencies, steering can help you
more than even the very best braking.
Locking Differential
If your vehicle has this feature, your locking
differential can give you additional traction on
snow, mud, ice, sand or gravel. It works like
a standard axle most of the time, but when one of
the wheels has no traction and the other does,
this feature will allow the wheel with traction
to move the vehicle.
Road Sensing Suspension
The Road Sensing Suspension (RSS) feature
provides superior vehicle ride and handling under
a variety of passenger and loading conditions.
The system is fully automatic and uses a computer
controller to continuously monitor vehicle speed,
wheel to body position, lift/dive and steering
position of the vehicle. The controller then sends
signals to each shock absorber to independently
adjust the damping level to provide the optimum
vehicle ride.
329
RSS also interacts with the tow/haul mode that,
when engaged, will provide additional control
of the shock absorbers. This additional control
results in better ride and handling characteristics
when the vehicle is loaded or towing a trailer.
See “Tow/Haul Mode” underTowing a Trailer on
page 379.
StabiliTrak®System
Your vehicle is equipped with StabiliTrak®, which
combines antilock brake, traction and stability
control systems and helps the driver maintain
directional control of the vehicle in most driving
conditions.
When you rst start your vehicle and begin to
drive away, the system performs several diagnostic
checks to insure there are no problems. You
may hear or feel the system working. This
is normal and does not mean there is a problem
with your vehicle. The system should initialize
before the vehicle reaches 20 mph (32 km/h).
In some cases, it may take approximately
two miles of driving before the system initializes.If the system fails to turn on or activate, the
STABILITRAK OFF or SERVICE STABILITRAK
message will be displayed. If the vehicle has gone
through heavy acceleration or braking or multiple
turns during the rst two miles of driving after
starting your vehicle, these messages may also
appear. If this is the case, your vehicle does
not need servicing. You will need to turn
the vehicle off and then restart it to initialize
StabiliTrak
®. If either message appears on the
Driver Information Center (DIC), and your vehicle
hasn’t gone through hard acceleration, braking
or multiple turns in the rst two miles of driving,
your vehicle should be taken in for service.
For more information on the stability messages,
seeDriver Information Center (DIC) on page 245.
StabiliTrak
®activates when the computer
senses that your vehicle is just starting to spin, as
it might if you hit a patch of ice or other slippery
spot on the road. When the system activates, you
may hear a noise or feel a vibration in the
brake pedal. This is normal. The system is
designed to help you in bad weather or other
difficult driving situations by making the most of
whatever road conditions will permit.
