Adding Equipment to the
Airbag-Equipped Vehicle
Q: Is there anything I might addto or change about the vehicle
that could keep the airbags
from working properly?
A: Yes. If you add things that
change the vehicle's frame,
bumper system, height, front
end or side sheet metal, they
may keep the airbag system
from working properly. Changing
or moving any parts of the front
seats, safety belts, the airbag
sensing and diagnostic module,
steering wheel, instrument
panel, roof-rail airbag modules,
ceiling headliner or pillar garnish
trim, front sensors, side impact
sensors, or airbag wiring can
affect the operation of the airbag
system.
In addition, the vehicle has a
passenger sensing system
for the right front 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).

Passenger Sensing
System on page 3‑37.

3-46 Seats and Restraints
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 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
and the safety belt continues
to tighten. Never leave children
unattended in a vehicle and never
allow children to play with the
safety belts.
Airbags plus lap‐shoulder belts
offer protection for adults and older
children, but not for young children and infants. Neither the vehicle's
safety belt system nor its airbag
system is designed for them. Every
time infants and young children ride
in vehicles, they should have the
protection provided by appropriate
child restraints.
Children who are not restrained
properly can strike other people,
or can be thrown out of the vehicle.

Where to Put the
Restraint
According to accident statistics,
children and infants are safer
when properly restrained in a child
restraint system or infant restraint
system secured in a rear seating
position.
We recommend that children and
child restraints be secured in a rear
seat, including: an infant or a child
riding in a rear-facing child restraint;
a child riding in a forward-facing
child seat; an older child riding in
a booster seat; and children, who
are large enough, using safety belts.
A label on your sun visor says,
“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 right
front passenger 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 right front
passenger airbag inflates and the
passenger seat is in a forward
position.
Even if the passenger sensing
system has turned off the right
front passenger frontal airbag,
no system is fail-safe. No one
can guarantee that an airbag will
not deploy under some unusual
circumstance, even though it is
turned off.
(Continued)
WARNING (Continued)
Secure rear-facing child
restraints in a rear seat, even
if the airbag is off. If you secure
a forward-facing child restraint in
the right front seat, always move
the front passenger seat as far
back as it will go. It is better to
secure the child restraint in a
rear seat.
SeePassenger Sensing System
on page 3‑37 for additional
information.
When securing a child restraint in
a rear seating position, study the
instructions that came with your
child restraint to make sure it is
compatible with this vehicle.
Child restraints and booster seats
vary considerably in size, and some
may fit in certain seating positions
better than others. Always make
sure the child restraint is properly
secured.

6. If the child restraint has a toptether, follow the child restraint
manufacturer's instructions
regarding the use of the top
tether. See Lower Anchors and
Tethers for Children (LATCH
System) on page 3‑52 for
more information.
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, reinstall it before
the seating position is used.
See
“Head Restraint Removal and
Reinstallation” underLower Anchors
and Tethers for Children (LATCH
System) on page 3‑52 for additional
information on installing 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 3‑51.
In addition, the vehicle has a
passenger sensing system which
is designed to turn off the right
front passenger frontal airbag
and seat‐mounted side impact
airbag under certain conditions.
See Passenger Sensing System on
page 3‑37 andPassenger Airbag
Status Indicator on page 5‑15
for more information, including
important safety information.

SeePassenger Sensing System
on page 3‑37 for additional
information. If the child restraint has the
LATCH system, see
Lower Anchors
and Tethers for Children (LATCH
System) on page 3‑52 for how and
where to install the child restraint
using LATCH. If a child restraint
is secured using a safety belt and
it uses a top tether, see Lower
Anchors and Tethers for Children
(LATCH System) on page 3‑52
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.

You will be using the lap-shoulder
belt to secure the child restraint in
this position. Follow the instructions
that came with the child restraint.
1. Move the seat as far back asit will go before securing the
forward-facing child restraint.
When the passenger sensing
system has turned off the
right front passenger frontal
airbag and seat‐mounted side
airbag, the off indicator on
the passenger airbag status
indicator should light and stay
lit when you start the vehicle.
See Passenger Airbag Status
Indicator on page 5‑15.
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. Push the latch plate into thebuckle until it clicks.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.5. Pull the shoulder belt all the wayout of the retractor to set the
lock. When the retractor lock is
set, the belt can be tightened but
not pulled out of the retractor.

6. To tighten the belt, push downon the 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 5 and 6.
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. If the airbags are 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 ”under Passenger
Sensing System on page 3‑37 for
more information.
To remove the child restraint,
unbuckle the vehicle safety belt and
let it return to the stowed position.
