Sensors
There is a solar sensor located on the instrument panel,
near the windshield.There is also an interior
temperature sensor
located to the right of the
steering wheel on the
instrument panel.
These sensors monitor the solar radiation and the
air inside your vehicle, then use the information to
maintain the selected temperature by initiating needed
adjustments to the temperature, the fan speed and the air
delivery system. The system may also supply cooler air to
the side of the vehicle facing the sun. The recirculation
mode will also be activated, as necessary. Do not cover
the sensors or the automatic climate control system will
not work properly.

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.
Static can occur on AM stations caused by things like
storms and power lines. Try reducing the treble to
reduce this noise.
FM Stereo
FM stereo will give the best sound, but FM signals will
reach only about 10 to 40 miles (16 to 65 km).
Tall buildings or hills can interfere with FM signals,
causing the sound to fade in and out.
XM™ Satellite Radio Service
XM™ Satellite Radio Service gives digital radio
reception from coast to coast. Just as with FM, tall
buildings or hills can interfere with satellite radio signals,
causing the sound to fade in and out. The radio may
display NO XM SIGNAL to indicate interference.

Section 4 Driving Your Vehicle
4-1

Control of a Vehicle
You have three systems that make your vehicle go where
you want it to go. They are the brakes, the steering and
the accelerator. All three systems have to do their work at
the places where the tires meet the road.
Sometimes, as when you are driving on snow or ice,
it is easy to ask more of those control systems than the
tires and road can provide. That means you can lose
control of your vehicle. Also seeStabilitrak
®System on
page 4-11.
Braking
Braking action involvesperception timeand
reaction time.
First, you have to decide to push on the brake pedal.
That isperception time.Then you have to bring up your
foot and do it. That isreaction time.
Averagereaction timeis about 3/4 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 3/4 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 (wet, dry, icy); tire
tread; the condition of your brakes; the weight of
the vehicle and the amount of brake force applied.
4-6

Remember: Anti-lock 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 anti-lock brakes.
Using Anti-Lock
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 anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the very best braking.
Traction Control System (TCS)
Your vehicle has a traction control system that limits
wheel spin. This is especially useful in slippery
road conditions. On a rear-wheel-drive vehicle, the
system operates if it senses that one or both of the
rear wheels are spinning or beginning to lose traction.
On an All-Wheel-Drive (AWD) vehicle the system
will operate if it senses that any of the wheels are
spinning or beginning to lose traction. When this
happens, the system brakes the spinning wheel(s)
and/or reduces engine power to limit wheel spin.
You may feel or hear the system working, but this is
normal.
This warning light will come
on to let you know if there’s
a problem with your traction
control system.
SeeTraction Control System (TCS) Warning Light on
page 3-42. When this warning light is on, the system will
not limit wheel spin. Adjust your driving accordingly.
4-9

Stabilitrak®System
Your vehicle is equipped with a vehicle stability
enhancement system called Stabilitrak®.Itisan
advanced computer controlled system that assists you
with directional control of the vehicle in difficult
driving conditions.
Stabilitrak
®activates when the computer senses a
discrepancy between your intended path and the
direction the vehicle is actually traveling. Stabilitrak
®
selectively applies braking pressure at any one of
the vehicle’s brakes to help steer the vehicle in the
direction which you are steering.
When the system activates, a Stability System Engaged
message will be displayed on the Driver Information
Center. SeeDIC Warnings and Messages on page 3-64.
You may also hear a noise or feel vibration in the
brake pedal. This is normal. Continue to steer the
vehicle in the direction you want it to go.
If there is a problem detected with Stabilitrak
®, a Service
Stability System message will be displayed on the Driver
Information Center. SeeDIC Warnings and Messages
on page 3-64. When this message is displayed, the
system is not operational. Driving should be adjusted
accordingly.Stabilitrak
®comes on automatically whenever you start
your vehicle. To help assist you with directional
control of the vehicle, you should always leave the
system on. You can turn Stabilitrak
®off if you ever
need to through the TC (traction control) on/off button.
SeeTraction Control System (TCS) on page 4-9.
If your vehicle is in cruise control when the Stabilitrak
®
activates, the cruise control will automatically
disengage. When road conditions allow you to safely
use it again, you may reengage the cruise control.
See “Cruise Control” underTurn Signal/Multifunction
Lever on page 3-8for more information.
Panic Brake Assist
Your vehicle has a panic brake assist system that
monitors the intention of the driver while braking. If the
system senses that the driver has applied hard/fast
pressure to the brake pedal, the system will generate
additional pressure, making it easier for the driver
to maintain brake application. When this happens the
brake pedal will feel easier to push. Just hold the brake
pedal down rmly and let the system work for you.
You may feel the brakes vibrate, or you may notice
some noise but this is normal. The brakes will return
to normal operation after the brake pedal has been
released.
