Calling are available on most vehicles. Not all OnStar
services are available on all vehicles. For more
information see the OnStar Owner's Guide or visit
www.onstar.com (U.S.) or www.onstar.ca (Canada),
contact OnStar at 1-888-4-ONSTAR (1‐888‐466‐7827)
or TTY 1‐877‐248‐2080, or press
Qto speak with an
OnStar advisor 24 hours a day, 7 days a week.
For a full description of OnStar services and system
limitations, see the OnStar Owner's Guide in the
glove box.
OnStar service is subject to the OnStar terms and
conditions included in the OnStar Subscriber
Information. OnStar service cannot work unless the vehicle is in a
place where OnStar has an agreement with a wireless
service provider for service in that area. OnStar service
also cannot work unless the vehicle is in a place where
the wireless service provider OnStar has hired for that
area has coverage, network capacity and reception
when the service is needed, and technology that is
compatible with the OnStar service. Not all services are
available everywhere, particularly in remote or enclosed
areas, or at all times.
The OnStar system can record and transmit vehicle
information. This information is automatically sent to an
OnStar call center when
Qis pressed,]is pressed,
or if the airbags or ACR system deploy. This information
usually includes the vehicle's GPS location and, in the
event of a crash, additional information regarding the
crash that the vehicle was involved in (e.g. the direction
from which the vehicle was hit). When the virtual
advisor feature of OnStar hands-free calling is used, the
vehicle also sends OnStar the vehicle's GPS location
so they can provide services where it is located.
Location information about the vehicle is only available
if the GPS satellite signals are unobstructed and
available.
1-28

The vehicle must have a working electrical system,
including adequate battery power, for the OnStar
equipment to operate. There are other problems OnStar
cannot control that may prevent OnStar from providing
OnStar service at any particular time or place. Some
examples are damage to important parts of the vehicle
in a crash, hills, tall buildings, tunnels, weather or
wireless phone network congestion.
OnStar Steering Wheel Controls
This vehicle may have a Talk/Mute button that can be
used to interact with OnStar hands-free calling. See
Audio Steering Wheel Controls
on page 4‑137for more
information.
On some vehicles, the mute button can be used to dial
numbers into voice mail systems, or to dial phone
extensions. See the OnStar Owner's Guide for more
information.
Your Responsibility
Increase the volume of the radio if the OnStar advisor
cannot be heard.
If the light next to the OnStar buttons is red, the system
may not be functioning properly. Press
Qand request a
vehicle diagnostic. If the light appears clear (no light is
appearing), your OnStar subscription has expired and
all services have been deactivated. Press

To save your positions in memory, do the following:1. Adjust the driver's seat, including the seatback recliner, both outside mirrors, steering wheel, and
the throttle and brake pedals to a comfortable
position.
See Outside Power Foldaway Mirrors
on
page 3‑40and Adjustable Throttle and Brake
Pedalon page 3‑26for more information.
Not all mirrors will have the ability to save and
recall the mirror positions.
2. Press and hold button 1 until two beeps sound.
A second seating, mirror, steering wheel position, and
throttle and brake pedal position can be programmed by
repeating the above steps and pressing button 2.
To recall the memory positions, the vehicle must be in
P (Park). Press and release either button 1 or button 2
corresponding to the desired driving position. The seat,
outside mirrors, steering wheel position, and adjustable
throttle and brake pedals will move to the position
previously stored. You will hear a single beep. If you use the remote keyless entry transmitter to enter
your vehicle and the remote recall memory feature is
on, automatic seat, mirror, steering wheel position, and
adjustable pedal movement will occur. See
“MEMORY
SEAT RECALL” underDIC Vehicle Customization (With
DIC Buttons)
on page 4‑67for more information.
To stop recall movement of the memory feature at any
time, press one of the power seat controls, memory
buttons, power mirror buttons, power tilt wheel control,
or adjustable pedal switch.
If something has blocked the driver ’s seat and/or the
adjustable pedals while recalling a memory position, the
driver ’s seat and/or the adjustable pedals recall may
stop working. If this happens, remove the obstruction
and press the appropriate function control for
two seconds. Then try recalling the memory position
again by pressing the appropriate memory button. If the
memory position is still not recalling, see your
dealer/retailer for service.

{WARNING:
A crash severe enough to inflate the airbags may
have also damaged important functions in the
vehicle, such as the fuel system, brake and
steering systems, etc. Even if the vehicle appears
to be drivable after a moderate crash, there may
be concealed damage that could make it difficult
to safely operate the vehicle.
Use caution if you should attempt to restart the
engine after a crash has occurred.In many crashes severe enough to inflate the airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger airbag..Airbags are designed to inflate only once. After an
airbag inflates, you will need some new parts for
the airbag system. If you do not get them, the
airbag system will not be there to help protect you
in another crash. A new system will include airbag
modules and possibly other parts. The service
manual for your vehicle covers the need to replace
other parts.
.The vehicle has a crash sensing and diagnostic
module which records information after a crash.
See
Vehicle Data Recording and Privacy
on
page 8‑18and Event Data Recorderson
page 8‑19.
.Let only qualified technicians work on the airbag
systems. Improper service can mean that an
airbag system will not work properly. See your
dealer/retailer for service.
2-65

When the passenger sensing system has turned off the
right front passenger frontal airbag, the off indicator will
light and stay lit to remind you that the airbag is off. See
Passenger Airbag Status Indicator on page 4‑32.
The passenger sensing system is designed to turn on
(may inflate) the right front passenger frontal airbag
anytime the system senses that a person of adult size is
sitting properly in the right front passenger seat.
When the passenger sensing system has allowed the
airbag to be enabled, the on indicator will light and stay
lit to remind you that the airbag is active.
For some children, including children in child restraints,
and for very small adults, the passenger sensing
system may or may not turn off the right front passenger
frontal airbag, depending upon the person's seating
posture and body build. Everyone in your vehicle who
has outgrown child restraints should wear a safety belt
properly—whether or not there is an airbag for that
person.
{WARNING:
If the airbag readiness light ever comes on and
stays on, it means that something may be wrong
with the airbag system. To help avoid injury to
yourself or others, have the vehicle serviced right
away. See Airbag Readiness Light
on page 4‑31
for more information, including important safety
information.
2-68

If the shoulder portion of the belt is pulled out all the
way, the child restraint locking feature will be engaged.
This may unintentionally cause the passenger sensing
system to turn the airbag off for some adult size
occupants. If this happens, let the belt go back all the
way and start again.
A thick layer of additional material, such as a blanket or
cushion, or aftermarket equipment such as seat covers,
seat heaters, and seat massagers can affect how well
the passenger sensing system operates. We
recommend that you not use seat covers or other
aftermarket equipment except when approved by GM
for your specific vehicle. SeeAdding Equipment to Your
Airbag-Equipped Vehicle
on page 2‑72for more
information about modifications that can affect how the
system operates.
The on indicator may be lit if an object, such as a
briefcase, handbag, grocery bag, laptop or other
electronic device, is put on an unoccupied seat. If this is
not desired remove the object from the seat.
{WARNING:
Stowing of articles under the passenger seat or
between the passenger seat cushion and
seatback may interfere with the proper operation
of the passenger sensing system.
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,
see Service Publications Ordering Information
on
page 8‑17.
{WARNING:
For up to 10 seconds after the ignition is turned off
and the battery is disconnected, an airbag can still
inflate during improper service. You can be injured
if you are close to an airbag when it inflates. 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 qualified to do so.
