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 the 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,
front sensors, side impact
sensors, rollover sensor module,
or airbag wiring can affect the
operation of the airbag system.In addition, the vehicle has a
passenger sensing system for the
right front passenger position,
which includes sensors that are
part of the passenger seat. The
passenger sensing system may
not operate properly if the original
seat trim is replaced with non-GM
covers, upholstery or trim, or with
GM covers, upholstery or trim
designed for a different vehicle.
Any object, such as an
aftermarket seat heater or a
comfort enhancing pad or device,
installed under or on top of the
seat fabric, could also interfere
with the operation of the
passenger sensing system.
This could either prevent proper
deployment of the passenger
airbag(s) or prevent the
passenger sensing system from
properly turning off the passenger
airbag(s). SeePassenger
Sensing System on page 1-55.If you have questions, call
Customer Assistance. The phone
numbers and addresses for
Customer Assistance are in Step
Two of the Customer Satisfaction
Procedure in this manual. See
Customer Satisfaction Procedure
on page 7-1.
If the vehicle has rollover
roof-rail airbags, seeDifferent
Size Tires and Wheels on
page 5-50for additional
important information.

With cruise control, a speed of
about 25 mph (40 km/h) or more can
be maintained without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below about 25 mph (40 km/h).
When the brakes are applied, the
cruise control is disengaged.
{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.

adjusting the temperature, fan
speed, and the air delivery mode.
The system may also supply cooler
air to the side of the vehicle
facing the sun. The recirculation
mode will also be used as needed
to maintain cool outlet temperatures.
Outlet Adjustment
Use the slider switch in the center
of the outlet, to change the direction
of the air ow. Use the thumbwheel
near the outlet to control the
amount of air ow or to shut off the

DIC Warnings and
Messages
Messages are displayed on the DIC
to notify the driver that the status
of the vehicle has changed and that
some action may be needed by
the driver to correct the condition.
Multiple messages may appear one
after another.
Some messages may not require
immediate action, but you can press
any of the DIC buttons on the
instrument panel or the trip odometer
reset stem on the instrument panel
cluster to acknowledge that you
received the messages and to clear
them from the display.
Some messages cannot be cleared
from the DIC display because
they are more urgent. These
messages require action before they
can be cleared. You should take
any messages that appear on
the display seriously and remember
that clearing the messages will
only make the messages disappear,
not correct the problem.The following are the possible
messages that can be displayed
and some information about them.ALL WHEEL DRIVE OFF
If your vehicle has the All-Wheel
Drive (AWD) system, this message
displays when there is a compact
spare tire on the vehicle, when
the Antilock Brake System (ABS)
warning light comes on, or when the
rear differential uid is overheating.
This message turns off when
the differential uid cools.
The AWD system is disabled until
the compact spare tire is replaced
by a full-size tire. If the warning
message is still on after putting on
the full-size tire, you need to reset
the warning message. To reset
the warning message, turn
the ignition off and then back on
again after 30 seconds. If the
message stays on, see your
dealer/retailer right away. See
All-Wheel Drive (AWD) System on
page 4-7for more information.
AUTOMATIC LIGHT
CONTROL OFF
This message displays when the
automatic headlamps are turned off.
This message clears itself after
10 seconds.
AUTOMATIC LIGHT
CONTROL ON
This message displays when the
automatic headlamps are turned on.
This message clears itself after
10 seconds.
BATTERY SAVER ACTIVE
This message displays when
the system detects that the battery
voltage is dropping below
expected levels. The battery saver
system starts reducing certain
features of the vehicle that you may
be able to notice. At the point
that the features are disabled, this
message is displayed. It means that
the vehicle is trying to save the
charge in the battery.

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.
Bluetooth Controls
Use the buttons located on the
steering wheel to operate the
in-vehicle Bluetooth system. See
Audio Steering Wheel Controls
on page 3-121for 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.
Pairing
A Bluetooth enabled cell phone
must be paired to the in-vehicle
Bluetooth system rst and then
connected to the vehicle before it
can be used. See the cell phone
manufacturers user guide for
Bluetooth functions before pairing
the cell phone. If a Bluetooth phone
is not connected, calls will be
made using OnStar
®Hands-Free
Calling, if available. Refer to
the OnStar owner’s guide for more
information.
Pairing Information:
Up to ve cell phones can be
paired to the in-vehicle
Bluetooth system.
The pairing process is disabled
when the vehicle is moving.
The in-vehicle Bluetooth system
automatically links with the rst
available paired cell phone in the
order the phone was paired.
Only one paired cell phone can
be connected to the in-vehicle
Bluetooth system at a time.
Pairing should only need to be
completed once, unless
changes to the pairing
information have been made or
the phone is deleted.
To link to a different paired phone,
see Linking to a Different Phone
later in this section.
Pairing a Phone
1. Press and hold
bgfor
two seconds. The system
responds with “Ready” followed
by a tone.
2. Say “Bluetooth”. The system
responds with “Bluetooth

with instructions and a four digit
PIN number. The PIN number
will be used in Step 4.
3-100 Instrument Panel

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 with a lot of
heavy braking. Keeping pace with
the traffic and allowing realistic
following distances eliminates a lot of
unnecessary braking. That means
better braking and longer brake life.
If the engine ever stops while the
vehicle is being driven, brake
normally but do not pump the
brakes. If the brakes are pumped,
the pedal could get harder to
push down. If the engine stops,there will still be some power brake
assist but it will be used when
the brake is applied. 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 vehicle
performance. SeeAccessories and
Modifications on page 5-3.
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,
and it might even be noticed that
the brake pedal moves a little. This
is normal.If there is a problem with ABS, this
warning light stays on. See
Antilock Brake System (ABS)
Warning Light on page 3-39.
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.
