{WARNING
If you cannot feel temperature
change or pain to the skin, the
seat heater may cause burns
even at low temperatures. To
reduce the risk of burns, people
with such a condition should use
care when using the seat heater,
especially for long periods of
time. Do not place anything on
the seat that insulates against
heat, such as a blanket, cushion,
cover, or similar item. This
may cause the seat heater to
overheat. An overheated seat
heater may cause a burn or may
damage the seat.

Seats and Restraints 3-39
The passenger sensing system is
designed to turn off the right front
passenger frontal airbag if:
.The right front passenger seat is
unoccupied.
.The system determines an infant
is present in a child restraint.
.A right front passenger takes
his/her weight off of the seat for
a period of time.
.There is a critical problem with
the airbag system or the
passenger sensing system.
When the passenger sensing
system has turned off the right front
passenger frontal airbag, the off
indicator will light and stay lit as a
reminder that the airbag is off. See
Passenger Airbag Status Indicator
on page 5‑17. 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 as a reminder 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 the
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 5‑16 for more
information, including important
safety information.
If the On Indicator is Lit for a
Child Restraint
If a child restraint has been installed
and the on indicator is lit:
1. Turn the vehicle off.
2. Remove the child restraint from the vehicle.
3. Remove any additional items from the seat such as blankets,
cushions, seat covers, seat
heaters, or seat massagers.

4. Reinstall the child restraintfollowing the directions
provided by the child restraint
manufacturer and refer to
Securing Child Restraints (Rear
Seat Position) on page 3‑60 or
Securing Child Restraints
(Center Front Seat Position) on
page 3‑63 orSecuring Child
Restraints (Right Front Seat
Position) on page 3‑64.
5. If, after reinstalling the child restraint and restarting the
vehicle, the on indicator is
still lit, turn the vehicle off.
Then slightly recline the vehicle
seatback and adjust the seat
cushion, if adjustable, to make
sure that the vehicle seatback is
not pushing the child restraint
into the seat cushion.
Also make sure the child
restraint is not trapped under
the vehicle head restraint.
If this happens, adjust the head
restraint. See Head Restraints
on page 3‑2. 6. Restart the vehicle.
The passenger sensing system
may or may not turn off the
airbag for a child in a child
restraint depending upon the
child’s seating posture and body
build. It is better to secure the
child restraint in a rear seat.
If the Off Indicator is Lit for an
Adult-Size Occupant
If a person of adult size is sitting in
the right front passenger seat, but
the off indicator is lit, it could be because that person is not sitting
properly in the seat. If this happens,
use the following steps to allow the
system to detect that person and
enable the right front passenger
frontal airbag:
1. Turn the vehicle off.
2. Remove any additional material
from the seat, such as blankets,
cushions, seat covers, seat
heaters, or seat massagers.
3. Place the seatback in the fully upright position.
4. Have the person sit upright in the seat, centered on the seat
cushion, with legs comfortably
extended.
5. Restart the vehicle and have the person remain in this position for
two to three minutes after the on
indicator is lit.

Additional Factors Affecting
System Operation
Safety belts help keep the
passenger in position on the
seat during vehicle maneuvers
and braking, which helps the
passenger sensing system
maintain the passenger airbag
status. See“Safety Belts” and
“Child Restraints” in the Index for
additional information about the
importance of proper restraint use.
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. See
Adding Equipment to
the Airbag-Equipped Vehicle on
page 3‑42 for 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 the
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 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 13‑16.
{WARNING
For up to 10 seconds after the
vehicle 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(Continued)
WARNING (Continued)
proper service procedures, and
make sure the person performing
work for you is qualified to do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Q: Is there anything I might addto 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,
or airbag wiring can affect the
operation of the airbag system.
In addition, the vehicle may have
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.

Radios with CD and DVD
Vehicles with a USB, CD, and DVD
radio have a Bose®Surround

under,
“Adjusting the Speakers
(Balance/Fade).”
Vehicles with a USB, CD, and DVD
radio may have a Rear Seat
Entertainment (RSE) system. See
Rear Seat Entertainment (RSE) System on page 7‑35
for more
information on the vehicle's RSE
system.

Operation Tips
.Keep the hood and front air
inlets free of ice, snow, or any
other obstruction (such as
leaves). The heater and
defroster will work far better,
reducing the chance of fogging
the inside of the windows.
.When you enter a vehicle in cold
weather, press the fan up button
to the maximum fan level before
driving. This helps clear the
intake ducts of snow and
moisture, and reduces the
chance of fogging the inside of
the window.
.Keep the air path under the front
seats clear of objects. This helps
air to circulate throughout the
vehicle.
.Adding outside equipment to the
front of the vehicle, such as
hood-air deflectors, may affect
the performance of the heating
and air conditioning system.
Check with your dealer before
adding equipment to the outside
of the vehicle.
