Passenger Sensing System
The vehicle has a passenger sensing system for the
right front passenger position. The passenger airbag
status indicator will be visible on the overhead console
when you start the vehicle.
United StatesCanada
The words ON and OFF, or the symbol for on and off,
will be visible during the system check. If you are using
remote start to start your vehicle from a distance,
if equipped, you may not see the system check. When
the system check is complete, either the word ON or
the word OFF, or the symbol for on or the symbol for off,
will be visible. See Passenger Airbag Status Indicator
on page 4‑55. The passenger sensing system will turn off the right
front passenger frontal airbag under certain conditions.
The driver airbag, seat‐mounted side impact airbags
and the roof‐rail airbags are not part of the passenger
sensing system.
The passenger sensing system works with sensors
that are part of the right front passenger seat. The
sensors are designed to detect the presence of a
properly-seated occupant and determine if the right
front passenger's frontal airbag should be enabled
(may inflate) or not.
According to statistics, children are safer when properly
secured in a rear seat in the correct child restraint for
their weight and size.
We recommend that children be secured in a rear seat,
including: an infant or a child riding in a rear-facing child
restraint; a child riding in a forward-facing child seat; an
older child riding in a booster seat; and children, who
are large enough, using safety belts.
A label on the sun visor says,
“Never put a rear-facing
child seat in the front.” This is because the risk to the
rear-facing child is so great, if the airbag deploys.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q: Is there anything I might add to or change aboutthe 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, or airbag wiring can affect the
operation of the airbag system.
In addition, your vehicle has a passenger sensing
system for the right front passenger's position, which
includes sensors that are part of the passenger's
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 2‑66.
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.
See Customer Satisfaction Procedure on page 8‑2.
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 8‑2.
In addition, your dealer and the service manual have
information about the location of the airbag sensors,
sensing and diagnostic module and airbag wiring.

Windows
{WARNING:
Leaving children, helpless adults, or pets in a
vehicle with the windows closed is dangerous.
They can be overcome by the extreme heat and
suffer permanent injuries or even death from heat
stroke. Never leave a child, a helpless adult, or a
pet alone in a vehicle, especially with the windows
closed in warm or hot weather.
The vehicle aerodynamics are designed to improve fuel
economy performance. This may result in a pulsing
sound when either rear window is down and the front
windows are up. To reduce the sound, open either a
front window or the sunroof (if equipped).

.Do not place anything on top of the driver side
floor mat.
.Use only a single floor mat on the driver side.
.Do not place one floor mat on top of another.
Convenience Net
Use the convenience net, located in the rear, to store
small loads as far forward as possible. The net should
not be used to store heavy loads.
Sunroof
If the vehicle has a power
sunroof, the switches are
located on the overhead
console.
To open or close the sunroof, the ignition must be on or
Retained Accessory Power (RAP) must be active. See
Retained Accessory Power (RAP) on page 3‑27.

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.
Cellular Phone Usage
Cellular phone usage may cause interference with
the vehicle's radio. This interference may occur
when making or receiving phone calls, charging the
phone's battery, or simply having the phone on. This
interference causes an increased level of static while
listening to the radio. If static is received while listening
to the radio, unplug the cellular phone and turn it off.
Backglass Antenna
The AM-FM antenna is integrated with the rear window
defogger, located in the rear window. Make sure that the
inside surface of the rear window is not scratched and
that the lines on the glass are not damaged. If the
inside surface is damaged, it could interfere with radio
reception. For proper radio reception, the antenna
connector needs to be properly attached to the post on
the glass. If a cellular telephone antenna needs to be attached to
the glass, make sure that the grid lines for the AM-FM
antenna are not damaged. There is enough space
between the grid lines to attach a cellular telephone
antenna without interfering with radio reception.
Notice:
Using a razor blade or sharp object to clear
the inside rear window can damage the rear window
antenna and/or the rear window defogger. Repairs
would not be covered by the vehicle warranty. Do
not clear the inside rear window with sharp objects.
Notice: Do not apply aftermarket glass tinting
with metallic film. The metallic film in some tinting
materials will interfere with or distort the incoming
radio reception. Any damage caused to your
backglass antenna due to metallic tinting materials
will not be covered by the vehicle warranty.
XM™ Satellite Radio Antenna
System
The XM Satellite Radio antenna is located on the roof
or the rear of the vehicle. Keep the antenna clear of
obstructions for clear radio reception.
