3-40 Seats and Restraints
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. SeeAdding Equipment to
the Airbag-Equipped Vehicle on
page 3-40 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 13-11.
{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

3-58 Seats and Restraints
If the position you are using
has a fixed head restraint
and you are using a single
tether, route the tether
around the inboard or
outboard side of the head
restraint.
If the position you are using
has a fixed or an adjustable
head restraint and you are
using a dual tether, route
the tether around the head
restraint.
3. Before placing a child in the child restraint, make sure it is
securely held in place. To check,
grasp the child restraint at the
LATCH path and attempt to move it side to side and back
and forth. There should be no
more than 2.5 cm (1 in) of
movement, for proper
installation.
Head Restraint Removal and
Reinstallation
1. Partially fold the seatback
forward. See Third Row Seats
on page 3-14 for additional
information.
2. Press the buttons on the head restraint posts, and pull up on
the head restraint. 3. When the child restraint is
removed, reinstall the head
restraint before the seating
position is used.
{Warning
With head restraints that are not
installed and adjusted properly,
there is a greater chance that
occupants will suffer a neck/
spinal injury in a crash. Do not
drive until the head restraints for
all occupants are installed and
adjusted properly.
4. Route the tether of the child restraint under the head
restraint.

3-60 Seats and Restraints
If the child restraint has the LATCH
system, seeLower Anchors and
Tethers for Children (LATCH
System) on page 3-50 for how and
where to install the child restraint
using LATCH. If a child restraint is
secured in the vehicle using a
safety belt and it uses a top tether,
see Lower Anchors and Tethers for
Children (LATCH System) on
page 3-50 for top tether anchor
locations.
Do not secure a child seat in a
position without a top tether anchor
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 strap
must be anchored.
In Canada, the law requires that
forward-facing child restraints have
a top tether, and that the tether be
attached.
If the child restraint or vehicle seat
position does not have the LATCH
system, you will be using the safety
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.
If more than one child restraint
needs to be installed in the rear
seat, be sure to read
Where to Put
the Restraint on page 3-49.
1. Put the child restraint on
the seat.
For the third row outboard
seating positions, if the head
restraint interferes with the
proper installation of the child
restraint, the head restraint may
be removed. See “Head
Restraint Removal and
Reinstallation” underLower
Anchors and Tethers for
Children (LATCH System) on
page 3-50.
2. 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.

3-62 Seats and Restraints
6. If the child restraint has a toptether, follow the child restraint
manufacturer ’s instructions
regarding the use of the top
tether. Refer to the instructions
that came with the child restraint
and see Lower Anchors and
Tethers for Children (LATCH
System) on page 3-50.
7. Before placing a child in the child restraint, make sure it is
securely held in place. To check,
grasp the child restraint at the
safety belt path and attempt to
move it side to side and back
and forth. When the child
restraint is properly installed,
there should be no more than
2.5 cm (1 in) of movement.
To remove the child restraint,
unbuckle the vehicle safety belt and
let it return to the stowed position.
If the top tether is attached to a top
tether anchor, disconnect it.
If the head restraint was removed
for a third row outboard seating
position, reinstall it before the seating position is used. See
“Head
Restraint Removal and
Reinstallation” underLower Anchors
and Tethers for Children (LATCH
System) on page 3-50 for additional
information on reinstalling the head
restraint properly.
Securing Child Restraints
(Front Passenger Seat)
This vehicle has airbags. A rear
seat is a safer place to secure a
forward-facing child restraint. See
Where to Put the Restraint on
page 3-49.
In addition, the vehicle has a
passenger sensing system which is
designed to turn off the front
outboard passenger frontal airbag
under certain conditions. See
Passenger Sensing System on
page 3-35 andPassenger Airbag
Status Indicator on page 5-18 for
more information, including
important safety information. 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.
{Warning
A child in a rear-facing child
restraint can be seriously injured
or killed if the front outboard
passenger frontal airbag inflates.
This is because the back of the
rear-facing child restraint would
be very close to the inflating
airbag. A child in a forward-facing
child restraint can be seriously
injured or killed if the front
outboard passenger frontal airbag
inflates and the passenger seat is
in a forward position.
Even if the passenger sensing
system has turned off the front
outboard passenger frontal
airbag, no system is fail-safe. No
one can guarantee that an airbag

7. Before placing a child in thechild restraint, make sure it is
securely held in place. To check,
grasp the child restraint at the
safety belt path and attempt to
move it side to side and back
and forth. When the child
restraint is properly installed,
there should be no more than
2.5 cm (1 in) of movement.
If the airbag is off, the off indicator in
the passenger airbag status
indicator will come on and stay on
when the vehicle is started.
If a child restraint has been installed
and the on indicator is lit, see “If the
On Indicator is Lit for a Child
Restraint” underPassenger Sensing
System on page 3-35 for more
information.
To remove the child restraint,
unbuckle the vehicle safety belt and
let it return to the stowed position.
