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 069
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 (Continued)
That could cause 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 theneed, for everyone, to use safety
restraints. In fact, the law in every
state in the United 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.
(Continued)
Warning (Continued)
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) (Continued)

{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
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,(Continued)
Warning (Continued)
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. If necessary,
move buckled seat belts to avoid
rubbing the LATCH attachments.(Continued)
Caution (Continued)
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 077.
Crew Cab
1. When installing a rear-facing
child restraint, it may be
necessary to move the front
seat forward to properly install
per the child restraint
manufacturer instructions.

If the position you are
using has a fixed head
restraint and you are
using a dual tether, route
the tether around the
sides of the head
restraint.
3.4. Adjust the top tether to itsfull length and attach the
top tether hook to the
anchor. Make sure that
you secure the top tether
to the top tether anchor
and not to the seatback
latch.
3.5. Push rearward on the seatback until it locks into
its upright position. Push
and pull on the seatback
to make sure it is secured
properly.
4. 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 seat belts and
the top tether. Refer to your
child restraint manufacturer

5. Tighten the top tether.
6. 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.
Extended Cab with Rear Seats
{Warning
Never secure a rear-facing or
forward-facing child restraint in
the left rear seating position in an
extended cab model. This seating
position is not suitable for child

installed properly, the front
passenger seat cannot be used.
1. Always install the seat cushion extension in the right rear

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) 078 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) 078 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.
