Heated Front Seats
{Warning
If you cannot feel temperature
change or pain to the skin, the
seat heater may cause burns. 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.
If available, the buttons are near the
climate controls. To operate, the
ignition must be in ON/RUN.
Press

passenger seat cushion and
seatback.
Press the button once for the
highest setting. With each press of
the button, the heated seat will
change to the next lower setting,
and then the off setting. Three lights
indicate the highest setting, and one
light indicates the lowest.
The passenger seat may take
longer to heat up. Remote Start Heated Seats
When it is cold outside, the heated
seats can be programmed to turn on
automatically during a remote
vehicle start. The heated seats will
be canceled when the ignition is
turned on. Press the heated seat
button to use the heated seats after
the vehicle is started.

.There is a critical problem with
the airbag system or the
passenger sensing system.
When the passenger sensing
system has turned off the front
outboard passenger frontal airbag,
the off indicator will light and stay lit
to remind you that the airbag is off.
See Passenger Airbag Status
Indicator 0106.
The passenger sensing system is
designed to turn on the front
outboard passenger frontal airbag
anytime the system senses that a
person of adult size is sitting
properly in the front outboard
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 front outboard 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 0105 for more information,
including important safety
information.
If the On Indicator is Lit for a
Child Restraint
The passenger sensing system is
designed to turn off the front
outboard passenger frontal airbag if
the system determines that an infant
is present in 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 restraint following the directions
provided by the child restraint
manufacturer and refer to
Securing Child Restraints (With
the Safety Belt in the Rear
Seat) 086 orSecuring Child
Restraints (With the Safety Belt
in the Front Seat) 088.
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.

70 Seats and Restraints
Also make sure the child
restraint is not trapped under
the vehicle head restraint.
If this happens, adjust the head
restraint. SeeHead
Restraints 046.
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 size. It is better to
secure the child restraint in a
rear seat. Never put a
rear-facing child restraint in the
front seat, even if the on
indicator is not lit.If the Off Indicator is Lit for an
Adult-Sized Occupant
If a person of adult size is sitting in
the front outboard passenger seat,
but the off indicator is lit, it could be
because that person is not sitting
properly in the seat. Use the
following steps to allow the system
to detect that person and enable the
front outboard 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.
{Warning
If the front outboard passenger
airbag is turned off for an
adult-sized occupant, the airbag
will not be able to inflate and help
protect that person in a crash,
resulting in an increased risk of
serious injury or even death. An
adult-sized occupant should not

Warning (Continued)
ride in the front outboard
passenger seat, if the passenger
airbag off 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.
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 072
for more information about
modifications that can affect how
the system operates.
A wet seat can affect the
performance of the passenger
sensing system. Here is how:
. The passenger sensing system
may turn off the passenger
airbag when liquid is soaked into
the seat. If this happens, the off
indicator will be lit, and the
airbag readiness light on the
instrument panel will also be lit.
. Liquid pooled on the seat that
has not soaked in may make it
more likely that the passenger
sensing system will turn on the
passenger airbag while a child
restraint or child occupant is on
the seat. If the passenger airbag
is turned on, the on indicator will
be lit.
If the passenger seat gets wet, dry
the seat immediately. If the airbag
readiness light is lit, do not install a
child restraint or allow anyone to occupy the seat. See
Airbag
Readiness Light 0105 for important
safety information.
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
Information0304.
{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
proper service procedures, and
make sure the person performing
work for you is qualified to do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change the
vehicle's frame, bumper system,
height, front end, or side sheet
metal, may keep the airbag system
from working properly. The
operation of the airbag system can
also be affected by changing any
parts of the front seats, safety belts,
airbag sensing and diagnostic
module, steering wheel, instrument
panel, any of the airbag modules,
ceiling or pillar garnish trim,
overhead console, front sensors,
side impact sensors, or airbag
wiring.
Your dealer and the service manual
have information about the location
of the airbag sensors, sensing and
diagnostic module, and airbag
wiring.
In addition, the vehicle has a
passenger sensing system for the
front outboard 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 067.
If the vehicle has rollover roof-rail
airbags, see Different Size Tires
and Wheels 0251 for additional
important information.
If you have to modify your vehicle
because you have a disability and
you have questions about whether
the modifications will affect the
vehicle's airbag system, or if you
have questions about whether the
airbag system will be affected if the
vehicle is modified for any other
