Seats and Restraints 2-39
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.
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). See
Passenger Sensing System
on
page 2‑33.
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 12‑1.
If the vehicle has rollover
roof-rail airbags, see Different
Size Tires and Wheels
on
page 9‑62for additional
important information. Q: Because I have a disability,
I have to get my vehicle
modified. How can I find out
whether this will affect my
airbag system?
A: 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 12‑1.

the service manual have information
about the location of the airbag
sensors, sensing and diagnostic
module and airbag wiring.

4-42 Instruments and Controls
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. 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
Steering Wheel Controls
on
page 4‑6for 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
Qto confirm that the OnStar
equipment is active.
