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 Seat Belt in the
Rear Seat) 079 or
Securing Child Restraints (With the
Seat Belt in the Front Seat) 081.
Make sure the seat belt retractor is
locked by pulling the shoulder belt
all the way out of the retractor
when installing the child restraint,
even if the child restraint is
equipped with a seat belt lock off.
When the retractor lock is set, the
belt can be tightened but not
pulled out of the retractor. 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 037.
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 or that the child
restraint locking feature is engaged.
Use the following steps to allow the
system to detect that person and
enable the front outboard passenger
frontal airbag and knee airbag: 1. Turn the vehicle off.

2. Remove any additional materialfrom 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. 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-sized occupants. If this
happens, unbuckle the belt, let the
belt go back all the way, and then
buckle the belt again without
pulling the belt out all the way.
6. 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
ride in the front outboard passenger
seat, if the passenger airbag OFF
indicator is lit.
Additional Factors Affecting
System Operation
Seat 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 “Seat 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 064 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 articles under the
passenger seat or between the
passenger seat cushion and
seatback may interfere with the
proper operation of the passenger
sensing system.

Warning (Continued)
serious or fatal injuries. The
shoulder belt should go over the
shoulder and across the chest.
Infants and Young Children
Everyone in a vehicle needs
protection! This includes infants and
all other children. Neither the distance
traveled nor the age and size of the
traveler changes the need, for
everyone, to use safety restraints. In
fact, the law in every state in theUnited States and in every Canadian
province says children up to some age
must be restrained while in a vehicle.
{Warning
Children can be seriously injured or
strangled if a shoulder belt is
wrapped around their neck. The
shoulder belt can tighten but
cannot be loosened if it is locked.
The shoulder belt locks when it is
pulled all the way out of the
retractor. It unlocks when the
shoulder belt is allowed to go all
the way back into the retractor, but
it cannot do this if it is wrapped
around a child’s neck. If the
shoulder belt is locked and
tightened around a child’s neck, the
only way to loosen the belt is to
cut it.
Never leave children unattended in
a vehicle and never allow children
to play with the seat belts.
Every time infants and young children
ride in vehicles, they should have the
protection provided by appropriate child restraints. Neither the vehicle's
seat belt system nor its airbag system
is designed for them.
Children who are not restrained
properly can strike other people,
or can be thrown out of the vehicle.
{Warning
Never hold an infant or a child
while riding in a vehicle. Due to
crash forces, an infant or a child
will become so heavy it is not
possible to hold it during a crash.
For example, in a crash at only
40 km/h (25 mph), a 5.5 kg (12 lb)
infant will suddenly become a
110 kg (240 lb) force on a person's
arms. An infant or child should be
secured in an appropriate child
restraint.

Warning (Continued)
Follow the instructions that came
with the child restraint and the
instructions in this manual.
{Warning
To reduce the risk of serious or
fatal injuries during a crash, do not
attach more than one child
restraint to a single anchor.
Attaching more than one child
restraint to a single anchor could
cause the anchor or attachment to
come loose or even break during a
crash. A child or others could be
injured.
{Warning
Children can be seriously injured or
strangled if a shoulder belt is
wrapped around their neck. The
shoulder belt can tighten but
cannot be loosened if it is locked.
The shoulder belt locks when it is(Continued)

pulled all the way out of the
retractor. It unlocks when the
shoulder belt is allowed to go all
the way back into the retractor, but
it cannot do this if it is wrapped
around a child’s neck. If the
shoulder belt is locked and
tightened around a child’s neck, the
only way to loosen the belt is to
cut it.
Buckle any unused seat belts
behind the child restraint so
children cannot reach them. Pull
the shoulder belt all the way out of
the retractor to set the lock, and
tighten the belt behind the child
restraint after the child restraint
has been installed.
Caution
Do not let the LATCH attachments
rub against the vehicle’s seat belts.
This may damage these parts.(Continued)
Caution (Continued)
If necessary, move buckled seat
belts to avoid rubbing the LATCH
attachments.
Do not fold the rear seatback when
the seat is occupied. Do not fold the
empty rear seat with a seat belt
buckled. This could damage the
seat belt or the seat. Unbuckle and
return the seat belt to its stowed
position, before folding the seat.
If you need to secure more than one
child restraint in the rear seat, see
Where to Put the Restraint 071.
1. Attach and tighten the lower attachments to the lower anchors.
If the child restraint does not have
lower attachments or the desired
seating position does not have
lower anchors, secure the child
restraint with the top tether and
the seat belt. Refer to the child
restraint manufacturer instructions
and the instructions in this
manual.
1.1. Find the lower anchors for the desired seating position.

1. Insert the head restraint posts intothe holes in the top of the
seatback. The notches on the posts
must face the driver side of the
vehicle.
2. Push the head restraint down. If necessary, press the height
adjustment release button to
further lower the head restraint.
See Head Restraints 037.
3. Try to move the head restraint to make sure that it is locked in place.
Replacing LATCH System
Parts After a Crash
{Warning
A crash can damage the LATCH
system in the vehicle. A damaged
LATCH system may not properly
secure the child restraint, resulting
in serious injury or even death in a
crash. To help make sure the
LATCH system is working properly
after a crash, see your dealer to
have the system inspected and any
necessary replacements made as
soon as possible. If the vehicle has the LATCH system
and it was being used during a crash,
new LATCH system parts may be
needed.
New parts and repairs may be
necessary even if the LATCH system
was not being used at the time of the
crash.
Securing Child Restraints
(With the Seat Belt in the
Rear Seat)
When securing a child restraint with
the seat belts in a rear seat position,
study the instructions that came with
the child restraint to make sure it is
compatible with this vehicle.
If the child restraint has the LATCH
system, see
Lower Anchors and Tethers
for Children (LATCH System) 072 for
how and where to install the child
restraint using LATCH. If a child
restraint is secured in the vehicle
using a seat belt and it uses a top
tether, see Lower Anchors and Tethers
for Children (LATCH System) 072 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 tether 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 seat belt
to secure the child restraint. Be sure
to follow the instructions that came
with the child restraint.
If more than one child restraint needs
to be installed in the rear seat, be sure
to read
Where to Put the Restraint 071.
1. Put the child restraint on the seat. 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" under
Lower Anchors and Tethers for
Children (LATCH System) 072.

When the retractor lock is set, the
belt can be tightened but not
pulled out of the retractor.5. To tighten the belt, push down onthe child restraint, pull the
shoulder portion of the belt to
tighten the lap portion of the belt,
and feed the shoulder belt back
into the retractor. When installing
a forward-facing child restraint, it
may be helpful to use your knee to
push down on the child restraint as
you tighten the belt.
Try to pull the belt out of the
retractor to make sure the retractor
is locked. If the retractor is not
locked, repeat Steps 4 and 5.
6. If the child restraint has a top tether, follow the child restraint
manufacturer's instructions

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 seat 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.
