Radio Personalization
For vehicles with a Navigation System, see the
Navigation System manual supplied with the vehicle for
more information on accessing the main menu and for
descriptions of the menu items for the Navigation system.

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.
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.

For persons under 21, it is against the law in every
U.S. state to drink alcohol. There are good medical,
psychological, and developmental reasons for
these laws.
The obvious way to eliminate the leading highway
safety problem is for people never to drink alcohol and
then drive.
Medical research shows that alcohol in a person’s
system can make crash injuries worse, especially
injuries to the brain, spinal cord, or heart. This means
that when anyone who has been drinking — driver
or passenger — is in a crash, that person’s chance of
being killed or permanently disabled is higher than if the
person had not been drinking.
Control of a Vehicle
The following three systems help to control your
vehicle while driving — brakes, steering, and accelerator.
At times, as when driving on snow or ice, it is easy to ask
more of those control systems than the tires and road can
provide. Meaning, you can lose control of your vehicle.
SeeTraction Control System (TCS) on page 4-10
andStabiliTrak
®System on page 4-6orEnhanced
StabiliTrak®on page 4-6.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3.
Braking
SeeBrake System Warning Light on page 3-62.
Braking action involves perception time and reaction
time. First, you have to decide to push on the brake
pedal. That is perception time. Then you have to bring
up your foot and do it. That is reaction time.
Average reaction time is about three-fourths of a
second. But that is only an average. It might be less
with one driver and as long as two or three seconds or
more with another. Age, physical condition, alertness,
coordination, and eyesight all play a part. So do alcohol,
drugs, and frustration. But even in three-fourths of a
second, a vehicle moving at 60 mph (100 km/h) travels
66 feet (20 m). That could be a lot of distance in an
emergency, so keeping enough space between
your vehicle and others is important.
And, of course, actual stopping distances vary greatly
with the surface of the road, whether it is pavement or
gravel; the condition of the road, whether it is wet, dry, or
icy; tire tread; the condition of the brakes; the weight of
the vehicle; and the amount of brake force applied.

Stability control activates when the computer senses a
difference between the intended path and the direction
the vehicle is actually traveling. Stability control
automatically adjusts the front road wheel steering
angle, modi es the suspension stiffness, and selectively
applies braking pressure at any one of the vehicle’s
brakes to help maintain directional control of the vehicle.
When the system activates, a STABILITY SYS
ACTIVE message displays on the Driver Information
Center (DIC). SeeDIC Warnings and Messages
on page 3-79. It is normal to hear a noise or feel
vibration in the brake pedal when the system is working.
Continue to steer the vehicle in the intended direction.
If cruise control is engaged when Enhanced StabiliTrak
activates, the cruise control will automatically disengage.
Cruise Control may be re-engaged when road conditions
allow. SeeCruise Control on page 3-16,orAdaptive
Cruise Control on page 3-20for more information.
Enhanced StabiliTrak comes on automatically in the
Stability Touring Mode, when the vehicle is started.
The Stability Touring Mode is recommended for normal
driving. Enhanced StabiliTrak also has Stability
Competitive Mode that is turned on by pressing the
Traction Control (TC) button twice quickly. This mode is
designed to be used by the performance consciousdriver who desires less stability control intervention.
SeeCompetitive Driving Mode on page 4-11. When the
Stability Control Competitive Mode has been activated,
traction control operates in competitive mode and
cannot be turned off. The STABILITY COMPETITIVE
MODE message will be displayed on the DIC.
SeeDIC Warnings and Messages on page 3-79.
When operating the vehicle in the Stability Competitive
Mode, the system provides less stability control
intervention. Driving should be adjusted accordingly.
When the Stability Competitive Mode has been selected,
the Active Steering and Magnetic Ride Control Touring
Mode is not available. These systems are automatically
changed to the Performance Mode, providing more
response to road conditions and quicker steering
response. For more information, see “Active Steering
and Magnetic Ride Control Mode” in the Index of
the vehicle’s Navigation Manual.
To assist with directional control of the vehicle, always
leave the system on. Stability control can be turned
off however, by using the TC button. SeeTraction
Control System (TCS) on page 4-10. The STABILITY
SYS OFF message will be displayed on the DIC.
SeeDIC Warnings and Messages on page 3-79.

If there is a problem detected with Enhanced StabiliTrak,
the SERVICE STABILITY SYS message will be
displayed on the DIC. SeeDIC Warnings and Messages
on page 3-79. When this message is displayed, the
system is not operating. Driving should be adjusted
accordingly.
When certain faults or vehicle conditions are detected,
the Stability control will automatically go into a secure
mode and the STABILITY SECURE MODE message will
be displayed on the DIC. When the Stability Secure
Mode is activated, the stability control system will
not respond to driver requests to change the stability
mode until the next ignition cycle or until the vehicle
condition or fault is returned to normal. When the
Stability Secure Mode is activated, other messages
may be displayed, such as SERVICE STEERING SYS,
SERVICE SUSPENSION SYS or CHECK TIRE
PRESSURE on the DIC. When the Stability Secure
Mode is activated, a larger degree of steering wheel
input at low vehicle speeds and a smaller degree
of steering wheel input at high vehicle speeds may be
required. Stability Secure Mode will be activated if
a compact spare tire is being used. SeeDIC Warnings
and Messages on page 3-79andCompact Spare
Tire on page 5-114.Persistent operation of the vehicle in the STABILITY
SECURE MODE may be an indication that the vehicle
needs to be serviced by your dealer/retailer.
When certain faults are present, the vehicle’s speed
may be limited and the SPEED LIMITED TO XXX
message will be displayed on the DIC. SeeDIC
Warnings and Messages on page 3-79. When the
vehicle’s speed is limited, other messages may
be displayed, such as SERVICE STABILITY SYS,
SERVICE STEERING SYS or SERVICE SUSPENSION
SYS on the DIC. Have the vehicle serviced by your
dealer/retailer.
Enhanced StabiliTrak and Traction Control
Mode Selection
Enhanced StabiliTrak can be operated in Touring Mode
or Competitive Mode. It can also be turned off. The
TC button is used to change stability control modes
(Touring, Competitive or Off) as well as to turn traction
control on or off. SeeTraction Control System (TCS)
on page 4-10. The following information describes
the operation of the TC button for changing Traction
Control and Stability Control Modes.
