For vehicles with a navigation
radio system, see the separate
Navigation System manual.
Bluetooth®
Vehicles with a Bluetooth system
can use a Bluetooth capable
cell phone with a Hands Free Pro le
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 overrides 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.

This device complies with RSS-210
of Industry Canada. Operation is
subject to the following two
conditions:
1. This device may not cause
interference.
2. This device must accept any
interference received, including
interference that may cause
undesired operation of the
device.
Changes or modi cations to this
system by other than an authorized
service facility could void
authorization to use this equipment.
Theft-Deterrent Feature
THEFTLOCK®is designed to
discourage theft of the vehicle’s radio
by learning a portion of the Vehicle
Identi cation Number (VIN). The
radio does not operate and LOCKED
displays if the radio is stolen or
moved to a different vehicle.When the when the ignition is in the
off position, a blinking red light on
the upper left side of the radio
indicates that THEFTLOCK
®
is armed.
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 likestorms 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.

Your Driving, the
Road, and the Vehicle
Driving for Better Fuel
Economy
Driving habits can affect fuel
mileage. Here are some driving tips
to get the best fuel economy
possible.
Avoid fast starts and accelerate
smoothly.
Brake gradually and avoid abrupt
stops.
Avoid idling the engine for long
periods of time.
When road and weather
conditions are appropriate, use
cruise control, if equipped.
Always follow posted speed limits
or drive more slowly when
conditions require.
Keep vehicle tires properly
in ated.

Antilock Brake
System (ABS)
This vehicle has the Antilock Brake
System (ABS), an advanced
electronic braking system that will
help prevent a braking skid.
When the engine is started and the
vehicle begins to drive away,
ABS checks itself. A momentary
motor or clicking noise might
be heard while this test is going on.
This is normal.
If there is a problem with ABS, this
warning light stays on. See
Antilock Brake System (ABS)
Warning Light on page 3-28.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
the driver steer around the
obstacle while braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls braking
pressure accordingly.Remember: ABS does not change
the time needed to get a foot
up to the brake pedal or always
decrease stopping distance. If you
get too close to the vehicle in
front of you, there will not be enough
time to apply the brakes if that
vehicle suddenly slows or stops.
Always leave enough room up
ahead to stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down rmly and
let antilock work. The brakes might
vibrate or some noise might be
heard, but this is normal.
Driving Your Vehicle 4-5

Braking in Emergencies
ABS allows the driver to steer
and brake at the same time. In many
emergencies, steering can help
more than even the very best
braking.
Brake Assist
This vehicle has a Brake Assist
feature designed to assist the driver
in stopping or decreasing vehicle
speed in emergency driving
conditions. This feature uses the
stability system hydraulic brake
control module to supplement the
power brake system under
conditions where the driver has
quickly and forcefully applied
the brake pedal in an attempt to
quickly stop or slow down the
vehicle. The stability system
hydraulic brake control module
increases brake pressure at each
corner of the vehicle until the
ABS activates. Minor brake pedal
pulsations or pedal movement
during this time is normal and the
driver should continue to applythe brake pedal as the driving
situation dictates The Brake Assist
feature will automatically disengage
when the brake pedal is released
or brake pedal pressure is quickly
decreased.
StabiliTrak®System
The vehicle has a vehicle stability
enhancement system called
StabiliTrak. It is an advanced
computer controlled system that
assists the driver with directional
control of the vehicle in difficult
driving conditions.
StabiliTrak activates when the
computer senses a discrepancy
between the intended path and the
direction the vehicle is actually
traveling. StabiliTrak selectively
applies braking pressure at any one
of the vehicle’s brakes to assist
the driver with keeping the vehicle
on the intended path.
When the vehicle is started and
begins to move, the system
performs several diagnostic checksto insure there are no problems.
The system may be heard or
felt while it is working. This is normal
and does not mean there is a
problem with the vehicle.
If cruise control is being used when
StabiliTrak activates, the cruise
control automatically disengages.
The cruise control can be
re-engaged when road conditions
allow. SeeCruise Control on
page 3-9.
If there is a problem detected with
StabiliTrak, a SERVICE STAB
SYS message displays on the Driver
Information Center (DIC). See
DIC Warnings and Messages on
page 3-37for more information.
When this message is displayed, the
system is not working. Adjust your
driving accordingly.
StabiliTrak comes on automatically
whenever the vehicle is started
and resets itself at each ignition
cycle. However, when the transfer
case is placed in Four-Wheel-Low
Lock mode, StabiliTrak is
