seats to work.
To heat the entire seat, press the horizontal button with
the heated seat and seatback symbol. Press the button to
cycle through the temperature settings of high, medium
and low and to turn the heated seat off. Indicator lights
will be lit to designate the level of heat selected: three for
high, two for medium, and one for low.To heat only the seatback, press the vertical button with
the heated seatback symbol. An indicator light on the
seatback button will be lit to designate that only the
seatback is being heated. Additional presses of
the seatback button will cycle through the heat levels for
the seatback only. Press the horizontal button again
to heat the whole seat.
The heated seats will be canceled after the ignition is
turned off. If you still want to use the heated seat feature
after you restart your vehicle, you will need to press
the heated seat button again.

If your vehicle has a rear seat, there is no top tether
anchor at the right front seating position. Do not secure
a child seat in this position if a national or local law
requires that the top tether be anchored or if the
instructions that come with the child restraint say that
the top tether must be anchored. SeeLower Anchors
and Tethers for Children (LATCH) on page 1-42if
the child restraint has a top tether.
You will be using the lap-shoulder belt to secure the
child restraint in this position. Be sure to follow the
instructions that came with the child restraint. Secure
the child in the child restraint when and as the
instructions say.
1. Your vehicle has a right front passenger’s frontal
airbag. SeeAirbag Off Switch on page 1-78. If your
child restraint is forward-facing, move the seat as far
back as it will go before securing the restraint in this
seat. SeeManual Seats on page 1-3orPower Seats
on page 1-4. If you need to use a rear-facing child
restraint in this seat, make sure the airbag is off once
the child restraint has been installed.
When the airbag off switch has turned off the right
front passenger’s frontal airbag, the off indicator
in the airbag off light should light and stay lit when
you turn the ignition to RUN or START. See
Airbag Off Light on page 3-35.2. Put the child restraint on the seat.
3. Pick up the latch plate, and run the lap and shoulder
portions of the vehicle’s safety belt through or
around the restraint. The child restraint instructions
will show you how.
4. Buckle the belt. Make sure the release button is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.

CAUTION: (Continued)
can guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend that
rear-facing child restraints be transported in
vehicles with a rear seat that will
accommodate a rear-facing child restraint,
whenever possible.
If you need to secure a forward-facing child restraint in
the right front seat position, move the seat as far
back as it will go before securing the forward-facing
child restraint. SeePower Seats on page 1-4orManual
Seats on page 1-3.
If your child restraint is equipped with the LATCH
system, seeLower Anchors and Tethers for Children
(LATCH) on page 1-42.
If your vehicle has a rear seat, there is no top tether
anchor at the right front seating position. Do not secure
a child seat in this position if a national or local law
requires that the top tether be anchored or if the
instructions that come with the child restraint say that
the top tether must be anchored. SeeLower Anchors
and Tethers for Children (LATCH) on page 1-42if
the child restraint has a top tether.You will be using the lap-shoulder belt to secure the
child restraint in this position. Be sure to follow the
instructions that came with the child restraint. Secure
the child in the child restraint when and as the
instructions say.
1. Your vehicle has a right front passenger’s frontal
airbag. SeePassenger Sensing System on
page 1-81. General Motors recommends that
rear-facing child restraints be secured in a rear seat,
even if the airbag is off. If your child restraint is
forward-facing, move the seat as far back as it will
go before securing the child restraint in this
seat. SeePower Seats on page 1-4orManual
Seats on page 1-3.
When the passenger sensing system has turned off
the right front passenger’s frontal airbag, the off
indicator in the passenger airbag status indicator
should light and stay lit when you turn the ignition to
RUN or START. SeePassenger Airbag Status
Indicator on page 3-37.

To turn off the right front passenger’s airbag, insert your
ignition key into the switch, push in, and move the
switch to the off position.
The airbag off light will come on to let you know that the
right front passenger’s airbag is off. The light will stay
on to remind you that the airbag is off. The right
front passenger’s airbag will remain off until you turn it
back on.
{CAUTION:
If the airbag readiness light ever comes on
when you have turned off the airbag, it means
that something may be wrong with the airbag
system. The right front passenger’s airbag
could inate even though the switch is off.
If your vehicle is a regular cab pickup or an
extended cab pickup and this ever happens,
do not let anyone whom the national
government has identied as a member of a
passenger airbag risk group sit in the right
front passenger’s position (for example, do not
secure a rear-facing child restraint in your
vehicle) until you have your vehicle serviced. United States

Passenger Sensing System
If your rearview mirror has one of the indicators pictured
in the following illustrations, your vehicle has a
passenger sensing system. The indicator will be visible
when you turn your ignition key to RUN or START.
The words ON and OFF or the symbol for on and off,
will be visible on the rearview mirror during 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.SeePassenger Airbag Status Indicator on page 3-37.If
your rearview mirror does not have either of the
indicators pictured below, then your vehicle does not
have the passenger sensing system.
The passenger sensing system will turn off the right
front passenger’s frontal airbag under certain conditions.
The driver’s airbag is not part of the passenger
sensing system. United States

Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. You do not want the system to
inate while someone is working on your vehicle. Your
dealer and the service manual have information
about servicing your vehicle and the airbag system. To
purchase a service manual, seeService Publications
Ordering Information on page 7-15.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an
airbag can still inate during improper service.
You can be injured if you are close to an
airbag when it inates. 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 qualied to do so.
The airbag system does not need regular maintenance.
Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front of the
vehicle that could keep the airbags from
working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, front end sheet metal or
height, they may keep the airbag system from
working properly. Also, the airbag system may not
work properly if you relocate any of the airbag
sensors. 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. SeeCustomer Satisfaction Procedure on
