Notice:Contact your dealer/retailer before adding
any equipment.
Adding audio or communication equipment could
interfere with the operation of the vehicle’s engine,
radio, or other systems, and could damage them.
Follow federal rules covering mobile radio and
telephone equipment.
The vehicle has 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 2-25for more information.
Bluetooth®
Vehicles with a Bluetooth system can use a Bluetooth
capable cell phone with a Hands Free Prole to make and
receive phone calls. The system can be used while the
key is in ON/RUN or ACC/ACCESSORY position. The
range of the Bluetooth system can be up to 30 ft. (9.1 m).
Not all phones support all functions, and not all phones
are guaranteed to work with the in-vehicle Bluetooth
system. See gm.com/bluetooth for more information on
compatible phones.
Voice Recognition
The Bluetooth system uses voice recognition to interpret
voice commands to dial phone numbers and name tags.
Noise:Keep interior noise levels to a minimum.
The system may not recognize voice commands if there
is too much background noise.
When to Speak:A short tone sounds after the system
responds indicating when it is waiting for a voice
command. Wait until the tone and then speak.
How to Speak:Speak clearly in a calm and
natural voice.
Audio System
When using the in-vehicle Bluetooth system, sound
comes through the vehicle’s front audio system speakers
and over-rides the audio system. Use the audio
system volume knob, during a call, to change the
volume level. The adjusted volume level remains in
memory for later calls. To prevent missed calls, a
minimum volume level is used if the volume is turned
down too low.

Traveling Across Regions
If driving across several states, the selected region
might have to be changed to represent the destination.
There are two ways to plan a destination when
traveling across regions.
The following method is suggested and provides the
most route guidance and map display functions:
1. Change the selected search area region as you get
closer to the destination. See “Setting the Search
Area” underMaps on page 4-38.
2. Enter the destination and route settings. SeeEnter
Destination on page 4-27for more information.
If not using the rst method, keep the currently
selected search area region and enter the destination.
This method allows a destination selection from the
easy planning route method or from the All Points of
Interest (POI) categories with the “All Search Areas”
comment for US Only. For example, Tourist is a category
that features this comment. SeeEnter Destination on
page 4-27for more information.If traveling in or to Canada and the regional border is
crossed, the only map scale views available are 4 mi,
8 mi, 31 mi, and 128 mi (8 km, 16 km, 64 km and
256 km). Change the selected search area region when
you get closer to the destination. See “Setting the Search
Area” underMaps on page 4-38for more information.
Keyless Access System
When the engine is started, Driver 1 or Driver 2 displays
on the screen. A message will not appear on the
screen if the driver is unknown. The number on the back
of the transmitter corresponds to driver 1 or driver 2.
The navigation system can store memory points for
drivers 1 and 2 individually. SeeKeyless Access System
Operation on page 2-5for more information.
OnStar®System
When using the OnStar®system, the audio system
mutes and the navigation voice prompts become
disabled during the call. The volume of the OnStar call
can be adjusted by using the steering wheel volume
controls. SeeOnStar
®System on page 2-42for
more information.

Navigation Audio System
Notice:Before adding any sound equipment to the
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/retailer. 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 can interfere with the
operation of the vehicle’s engine, radio, or other
systems, and even damage them. The vehicle’s
systems can interfere with the operation of sound
equipment that has been added.
The 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 2-25for more
information.
The audio system is operated using navigation system
menus. The audio menus are explained in this section.

Braking
SeeBrake System Warning Light on page 3-47.
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.Avoid needless heavy braking. Some people drive
in spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic. This is
a mistake. The brakes might not have time to cool
between hard stops. The brakes will wear out much
faster if you do a lot of heavy braking. If you keep pace
with the traffic and allow realistic following distances,
you will eliminate a lot of unnecessary braking.
That means better braking and longer brake life.
If your vehicle’s engine ever stops while you are driving,
brake normally but do not pump the brakes. If you do,
the pedal could get harder to push down. If the
engine stops, you will still have some power brake
assist. But you will use it when you brake. Once the
power assist is used up, it can take longer to stop and
the brake pedal will be harder to push.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 6-3.
5-4

Antilock Brake System (ABS)
Your vehicle has the Antilock Brake System (ABS),
an advanced electronic braking system that will
help prevent a braking skid.
When you start the engine and begin to drive away,
ABS will check itself. You might hear a momentary
motor or clicking noise while this test is going on, and
you might even notice that the brake pedal moves
a little. This is normal.
If there is a problem with
ABS, this warning light will
stay on. SeeAntilock Brake
System (ABS) Warning
Light on page 3-48.
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 the 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 to each wheel, as
required, faster than any driver could. This can help
you steer around the obstacle while braking hard.
As you brake, the computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.
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 the 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 antilock work for you. You might hear
a motor or clicking noise and feel the brake pedal
move a little during a stop, but this is normal.

Performance Mode — XLR-V Only
Notice:When traction control is turned off, or
Performance Mode is active, it is possible to lose
traction. If a shift is attempted with the rear wheels
spinning with a loss of traction, it is possible to
cause damage to the transmission. Do not attempt to
shift when the rear wheels do not have traction.
Damage caused by misuse of the vehicle is not
covered. See the warranty book for additional
information.
For vehicles with this feature, the Performance Mode
can be selected by pressing the TCS/StabiliTrak button
on the console two times quickly. PERFORMANCE
MODE comes on the DIC. Performance Mode allows the
driver to have full control of the rear wheels while the
StabiliTrak System helps maintain directional control of
the vehicle by applying the brakes as necessary.
The TCS/StabiliTrak light will not be on. The TCS will
not be operating. Adjust your driving accordingly.
When the TCS/StabiliTrak button is pressed again, the
StabiliTrak and Traction Control Systems will be on.
The TRAC/STABILITRAK ON message will be displayed
briey in the DIC and a chime will be heard.
Traction Control System (TCS)
The 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 3-60. The system may be
heard or felt while it is working, but this is normal.
If cruise control is being used when the traction control
system begins to limit wheel spin, the cruise control
will automatically disengage. Cruise control may be
reengaged when road conditions allow. SeeAdaptive
Cruise Control on page 3-14orCruise Control on
page 3-11for more information.
