Servicing Your Airbag-Equipped
Vehicle
Airbags affect how the vehicle should be serviced.
There are parts of the airbag system in several places
around the vehicle. Your dealer/retailer and the
service manual have information about servicing the
vehicle and the airbag system. To purchase a service
manual, seeService Publications Ordering Information
on page 7-15.
{CAUTION:
For up to 10 seconds after the ignition is turned off
and the battery is disconnected, an airbag can still
inate during improper service. You can be injured
if you are close to an airbag when it inates. Avoid
yellow connectors. They are probably part of the
airbag system. Be sure to follow proper service
procedures, and make sure the person performing
work for you is qualied to do so.
Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to or change
about the vehicle that could keep the airbags
from working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. Changing or moving any parts
of the front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel, instrument
panel, roof-rail airbag modules, ceiling headliner
or pillar garnish trim, overhead console, front
sensors, side impact sensors, rollover sensor
module, or airbag wiring can affect the operation of
the airbag system.
If you have any questions about this, you should
contact Customer Assistance before you modify
your vehicle. The phone numbers and addresses for
Customer Assistance are in Step Two of the
Customer Satisfaction Procedure in this manual.
SeeCustomer Satisfaction Procedure on page 7-2.
If your vehicle has rollover roof-rail airbags, seeDifferent
Size Tires and Wheels on page 5-74for additional
important information.

Driver Shift Control (DSC)
The vehicle has Driver Shift Control (DSC). DSC
controls the transmission and vehicle speed while driving
down hill or towing a trailer by allowing you to select
a desired range of gears.
To use this feature:
1. Move the shift lever to the M (Manual Mode).
This will force a downshift from the current gear,
for gears 3 through 6.
2. Press the (+) plus or (−) minus button on the left
side of the steering wheel, to select the desired
range of gears for current driving conditions.When in the M (Manual Mode) a number will display
next to the M, indicating the maximum available gear.
The DIC display will show the message MANUAL SHIFT
on the rst line and the maximum available gear will be
displayed on the second line. SeeDriver Information
Center (DIC) on page 3-46andDIC Operation and
Displays (Using DIC Buttons) on page 3-47orDIC
Operation and Displays (Using Trip Odometer Reset
Stem) on page 3-52for more information. The number
displayed in the DIC is the highest gear available.
The transmission will be limited to the gear selected and
lower gears. Shifting will occur normally while driving,
however the cluster will continue to display the maximum
available gear. Higher gears will not be available unless
the selection is changed to include higher gears using
the (+) plus button.
Grade Braking is not available when the Driver Shift
Control is active. SeeTow/Haul Mode on page 2-36and
Towing a Trailer on page 4-55for more information.
While using the DSC, cruise control and the tow/haul
mode can be used.

Cruise Control
{CAUTION:
Cruise control can be dangerous where you cannot
drive safely at a steady speed. So, do not use the
cruise control on winding roads or in heavy traffic.
Cruise control can be dangerous on slippery roads.
On such roads, fast changes in tire traction can
cause excessive wheel slip, and you could lose
control. Do not use cruise control on slippery roads.
With cruise control, a speed of about 25 mph (40 km/h)
or more can be maintained without keeping your foot
on the accelerator. This can really help on long trips.
Cruise control does not work at speeds below about
25 mph (40 km/h).
When the brakes are applied, cruise control is
turned off.
If the vehicle has the StabiliTrak
®system or Traction
Control system (TCS) and begins to limit wheel spin
while you are using cruise control, the cruise control
automatically disengages. SeeStabiliTrak
®System on
page 4-6orTraction Control System (TCS) on page 4-9.
When road conditions allow the cruise control to be safely
uses again, it can be turned back on.The cruise control buttons
are located on the left side
of the steering wheel.
T(On/Off):Press to turn the system on or off.
The indicator light on the button turns on when cruise
control is on and turns off when cruise control is off.
+ RES (Resume/Accelerate):Press to make the
vehicle accelerate or resume to a previously set speed.
SET−(Set/Coast):Press to set the speed or make
the vehicle decelerate.
[(Cancel):Press to cancel cruise control without
erasing the set speed from memory.

enabled through the EASY EXIT SETUP menu,
the driver’s seat will move back, and if the vehicle has
the power tilt wheel steering feature, the power steering
column will move up when the key is removed from
the ignition or after pressing the easy exit seat button.
The automatic easy exit seat movement will only
occur one time after the key is removed from the
ignition. If the automatic movement has already
occurred, and you put the key back in the ignition and
remove it again, the seat and steering column will stay in
the original exit position, unless a memory recall took
place prior to removing the key again.NO CHANGE:No change will be made to this feature.
The current setting will remain.
To select a setting, press the set/reset button while the
desired setting is displayed on the DIC.

Navigation/Radio System
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 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 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.
Bluetooth Controls
Use the buttons located on the steering wheel to
operate the in-vehicle Bluetooth system. SeeAudio
Steering Wheel Controls on page 3-129for more
information.
bg(Push To Talk):Press to answer incoming calls,
to conrm system information, and to start speech
recognition.
cx(Phone On Hook):Press to end a call, reject a
call, or to cancel an operation.

Antilock Brake System (ABS)
This vehicle has the Antilock Brake System (ABS), an
advanced electronic braking system that helps 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
the ABS, this warning light
stays on. SeeAntilock
Brake System (ABS)
Warning Light on
page 3-38.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 front wheel
and at both rear wheels.
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.
4-5

Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not overdriving
those conditions. But skids are always possible.
The three types of skids correspond to the vehicle’s
three control systems. In the braking skid, the wheels are
not rolling. In the steering or cornering skid, too much
speed or steering in a curve causes tires to slip and lose
cornering force. And in the acceleration skid, too much
throttle causes the driving wheels to spin.
If the vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want
the vehicle to go. If you start steering quickly enough,
the vehicle may straighten out. Always be ready for
a second skid if it occurs.Of course, traction is reduced when water, snow, ice,
gravel, or other material is on the road. For safety, slow
down and adjust your driving to these conditions. It is
important to slow down on slippery surfaces because
stopping distance is longer and vehicle control more
limited.
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration, or
braking, including reducing vehicle speed by shifting to a
lower gear. Any sudden changes could cause the tires to
slide. You might not realize the surface is slippery until
the vehicle is skidding. Learn to recognize warning
clues —such as enough water, ice, or packed snow on
the road to make a mirrored surface — and slow down
when you have any doubt.
Remember: Any Antilock Brake System (ABS) helps
avoid only the braking skid.

Getting Familiar with Off-Road Driving
It is a good idea to practice in an area that is safe
and close to home before you go into the wilderness.
Off-roading requires some new and different skills.
Tune your senses to different kinds of signals. Your eyes
need to constantly sweep the terrain for unexpected
obstacles. Your ears need to listen for unusual tire
or engine sounds. Use your arms, hands, feet, and body
to respond to vibrations and vehicle bounce.
Controlling the vehicle is the key to successful off-road
driving. One of the best ways to control the vehicle
is to control the speed. At higher speeds:
You approach things faster and have less time
to react.
There is less time to scan the terrain for obstacles.
The vehicle has more bounce when driving over
obstacles.
More braking distance is needed, especially on an
unpaved surface.
{CAUTION:
When you are driving off-road, bouncing and quick
changes in direction can easily throw you out of
position. This could cause you to lose control and
crash. So, whether you are driving on or off the
road, you and your passengers should wear
safety belts.
Scanning the Terrain
Off-road driving can take you over many different kinds
of terrain. Be familiar with the terrain and its many
different features.
Surface Conditions:Off-roading surfaces can be
hard-packed dirt, gravel, rocks, grass, sand, mud, snow,
or ice. Each of these surfaces affects the vehicle’s
steering, acceleration, and braking in different ways.
Depending on the surface, slipping, sliding, wheel
spinning, delayed acceleration, poor traction, and longer
braking distances can occur.
