PTY (Program Type) Presets:The six presets
let you return to your favorite PTYs. These presets
have factory PTY preset stations. See “RDS
Program Type (PTY) Selections” later in
this section. You can set up to 12 PTYs, 6 FM 1
and 6 FM2. To save a PTY preset, do the
following:
1. Touch FM1 or FM2.
2. Touch RDS to enter the RDS menu.
3. Touch RDS ON/OFF to turn RDS on.
4. Touch PTY.
5. Touch SEL PTY and select the desired PTY
from the list.
6. Touch and hold one of the six presets for
more than two seconds until you hear a
beep. Whenever you touch that numbered
preset for less than two seconds, the PTY you
set will return.
7. Repeat the steps for each preset.
Once you have stored a PTY for each of your
preset stations, you can recall a PTY preset
by touching the preset station for less than
two seconds. Then use TUNE/SEEK or SCAN
to locate a station for that PTY selection.ALERT:This type of announcement warns of
national or local emergencies. You will not be able
to turn off alert announcements. Alert
announcements will come on even if RDS mode is
turned off. ALERT appears on the display when
an alert announcement plays. The audio
system uses TA volume during these
announcements. To increase volume, touch the
VOL button on your steering wheel or use the VOL
up and down buttons during the announcement.
See “Voice Guidance Volume Settings” under
Setup Menu on page 243for more information.
When an alert announcement comes on the tuned
radio station or a related network station, you
will hear it even if the volume is muted or a CD is
playing. If the audio system tunes to a related
network station for an alert announcement, it will
return to the original station when the
announcement is nished. If the CD player is
playing, the player will stop for the announcement
and resume when the announcement is nished.

To select HOME and AWAY preset stations, do
the following:
1. With the audio system on, touch the Audio
hard key and turn the audio system off.
2. Touch the HOME or AWAY button from the
main audio screen.
The next time the audio system is turned on,
the system will recall the last active preset
selection.
When battery power is removed and later applied,
you will not have to reset your home audio
system preset stations because the audio system
remembers them. However, you will have to
reset your away radio preset stations.
Voice Recognition
The navigation system’s voice recognition allows
for hands-free operation of navigation and
audio system features. Voice recognition can be
used when the ignition is on or when Retained
Accessory Power (RAP) is active.This feature only works if the map DVD is inserted
and I AGREE has been selected. If you try to
use voice recognition without the map DVD
inserted, the system will display “Please insert the
navigation map DVD to use the voice recognition
feature.”
To use navigation voice recognition, do the
following:
1. Press the talk
symbol steering
wheel control
and release it, when
you hear a beep.
The audio system, if
on, will mute.
2. Clearly state one of the commands listed on
the following pages. For example, say “FM1”.
3. The system will tell you the command being
implemented. For example, the system will
say “FM1 Radio” and change the audio
system to the FM1 source.

Let us say the road is wet and you are driving
safely. Suddenly, an animal jumps out in front of
you. You slam on the brakes and continue braking.
Here is what happens with ABS:
A computer senses that wheels are slowing down.
If one of the wheels is about to stop rolling, the
computer will separately work the brakes at each
wheel.ABS can change the brake pressure faster than
any driver could. The computer is programmed to
make the most of available tire and road
conditions. This can help you steer around the
obstacle while braking hard.
As you brake, your computer keeps receiving
updates on wheel speed and controls braking
pressure accordingly.
328
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 hear a motor or clicking noise and
feel the brake pedal move a little during a stop,
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.
Traction Control System (TCS)
Your vehicle has a traction control system that
limits wheel spin. This is especially useful in
slippery road conditions. The system operates only
if it senses that one or both of the rear wheels
are spinning or beginning to lose traction. When
this happens, the system works the rear brakes
and reduces engine power to limit wheel spin.
The TRAC SYSTEM ACTIVE message will display
on the Driver Information Center (DIC) when the
traction control system is limiting wheel spin.
SeeDIC Warnings and Messages on page 206.
You may feel or hear the system working, but this
is normal.
If your vehicle is in cruise control when the
traction control system begins to limit wheel spin,
the cruise control will automatically disengage.
When road conditions allow you to safely
use it again, you may reengage the cruise control.
SeeAdaptive Cruise Control on page 150or
Cruise Control on page 147for more information.
329
This warning light will
come on to let you
know if there is
a problem with your
traction control system.
SeeTraction Control System (TCS) Warning Light
on page 194. When this warning light is on, the
system will not limit wheel spin. Adjust your driving
accordingly.
The traction control system automatically comes
on whenever you start your vehicle. To limit wheel
spin, especially in slippery road conditions, you
should always leave the system on. But you
can turn the traction control system off if you ever
need to. You should turn the system off if your
vehicle ever gets stuck in sand, mud or snow and
rocking the vehicle is required. SeeRocking
Your Vehicle to Get It Out on page 354andIf Your
Vehicle is Stuck in Sand, Mud, Ice, or Snow on
page 353for more information.To turn the system off,
press the front part of
the traction control
button located on the
center console.
The TRACTION SYSTEM OFF message will
display on the DIC and the traction control system
warning light will come on. If the system is
limiting wheel spin when you press the button,
the TRACTION SYSTEM OFF message will
display – but the system will not turn off right away.
It will wait until there is no longer a current need
to limit wheel spin.
You can turn the system back on at any time by
pressing the button again. The TRACTION
SYSTEM ON message should display brie y on
the Driver Information Center. SeeDIC Warnings
and Messages on page 206for more information.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modi cations on page 363for more information.

Magnetic Ride Control
Magnetic Ride Control automatically adjusts the
ride of your vehicle. Automatic ride control is
achieved through a computer used to control and
monitor the suspension system. The controller
receives input from various sensors to determine
the proper system response. If the controller
detects a problem within the system, the DIC will
display a SERVICE RIDE CONTROL message.
SeeDIC Warnings and Messages on page 206for
more information. See your dealer for service.
Limited-Slip Rear Axle
Your limited-slip rear axle 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 rear wheels has no traction
and the other does, this feature will allow
the wheel with traction to move the vehicle.
StabiliTrak®System
The StabiliTrak®System is a computer controlled
system that helps the driver maintain directional
control of the vehicle in difficult driving conditions.
This is accomplished by selectively applying
any one of the vehicle’s brakes.
When you rst start your vehicle and begin to
drive away (6 mph (10 km/h)), especially during
cold weather, the message STABILITRAK
WARMING may be displayed in the Driver
Information Center (DIC), the instrument panel
cluster light will be on, and a chime will sound.
This is normal. You can acknowledge this
message by pressing the RESET button. The
StabiliTrak
®System performance is affected until
the message, STABILITRAK READY, is
displayed in the DIC. This can take up to
15 minutes.
The WAIT FOR STABILITRAK message may be
displayed in the DIC after exceeding 19 mph
(30 km/h) for 10 seconds if the steering is
not centered. The system is off until the
STABILITRAK ACTIVE message is displayed.

Steering
Power Steering
If you lose power steering assist because the
engine stops or the system is not functioning, you
can steer but it will take much more effort.
Magnetic Speed Variable Assist
Steering
Your vehicle has a steering system that
continuously adjusts the effort you feel when
steering at all vehicle speeds. It provides ease
when parking, yet a rm, solid feel at highway
speeds.
Steering Tips
It is important to take curves at a reasonable
speed.
A lot of the “driver lost control” accidents mentioned
on the news happen on curves. Here is why:
Experienced driver or beginner, each of us is
subject to the same laws of physics when driving
on curves. The traction of the tires against the
road surface makes it possible for the vehicle to
change its path when you turn the front wheels.If there is no traction, inertia will keep the vehicle
going in the same direction. If you have ever
tried to steer a vehicle on wet ice, you will
understand this.
The traction you can get in a curve depends on
the condition of the tires and the road surface, the
angle at which the curve is banked, and your
speed. While you are in a curve, speed is the one
factor you can control.
Suppose you are steering through a sharp curve.
Then you suddenly accelerate. Both control
systems — steering and acceleration — have to
do their work where the tires meet the road.
Adding the sudden acceleration can demand too
much of those places. You can lose control.
SeeTraction Control System (TCS) on page 329.
What should you do if this ever happens? Ease
up on the accelerator pedal, steer the vehicle the
way you want it to go, and slow down.
Speed limit signs near curves warn that you
should adjust your speed. Of course, the posted
speeds are based on good weather and road
conditions. Under less favorable conditions you will
want to go slower.
333
If you need to reduce your speed as you approach
a curve, do it before you enter the curve, while
the front wheels are straight ahead.
Try to adjust your speed so you can “drive”
through the curve. Maintain a reasonable, steady
speed. Wait to accelerate until you are out of
the curve, and then accelerate gently into
the straightaway.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modi cations on page 363.
Steering in Emergencies
There are times when steering can be more
effective than braking. For example, you come
over a hill and nd a truck stopped in your lane, or
a car suddenly pulls out from nowhere, or a
child darts out from between parked cars and
stops right in front of you. You can avoid these
problems by braking — if you can stop in time. But
sometimes you cannot; there is not room. That
is the time for evasive action — steering around
the problem.
Your vehicle can perform very well in emergencies
like these. First apply your brakes.SeeBraking on page 326. It is better to remove as
much speed as you can from a possible collision.
Then steer around the problem, to the left or
right depending on the space available.
An emergency like this requires close attention
and a quick decision. If you are holding the
steering wheel at the recommended 9 and
3 o’clock positions, you can turn it a full
180 degrees very quickly without removing either
hand. But you have to act fast, steer quickly,
and just as quickly straighten the wheel once you
have avoided the object.
