If the On Indicator is Lit for 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 fromthe 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
(Rear Seat Position) on
page 3‑62 orSecuring Child
Restraints (Center Front Seat
Position) on page 3‑64 or
Securing Child Restraints
(Right Front Seat Position) on
page 3‑64.
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
on page 3‑2.
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 seating posture and body
build. It is better to secure the
child restraint in a rear seat.

3-42 Seats and Restraints
If the Off Indicator is Lit for an
Adult-Size Occupant
If a person of adult size is
sitting in the right front passenger
seat, but the off indicator is lit,
it could be because that person
is not sitting properly in the seat.If this happens, use the following
steps to allow the system to detect
that person and enable the right
front passenger frontal airbag:
1. Turn the vehicle off.
2. Remove any additional material
from 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. Restart the vehicle and have the person remain in this position for
two to three minutes after the on
indicator is lit.
Additional Factors Affecting
System Operation
Safety 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
“Safety Belts” and“Child Restraints”
in the Index for additional
information about the importance of
proper restraint use.
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‐size occupants. If this
happens, let the belt go back all the
way and start again.

Seats and Restraints 3-43
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 3‑44 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 13‑15.
{WARNING
For up to 10 seconds after the
ignition 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
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, overhead console, front
sensors, side impact sensors,
or airbag wiring can affect the
operation of the airbag system.
In addition, the vehicle may
have 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). See
Passenger Sensing System on
page 3‑38.

In addition, your dealer and the
service manual have information
about the location of the airbag
sensors, sensing and diagnostic
module and airbag wiring.
Airbag System Check
The airbag system does not need
regularly scheduled maintenance or
replacement. Make sure the airbag
readiness light is working.
See Airbag Readiness Light on
page 5‑18 for more information.
Notice: If an airbag covering is
damaged, opened, or broken, the
airbag may not work properly.
Do not open or break the airbag
coverings. If there are any
opened or broken airbag covers,
have the airbag covering and/or
airbag module replaced. For the location of the airbag
modules, see
What Makes an
Airbag Inflate? on page 3‑35.
See your dealer for service.
Replacing Airbag System
Parts After a Crash
{WARNING
A crash can damage the
airbag systems in your vehicle.
A damaged airbag system may
not work properly and may
not protect you and your
passenger(s) in a crash, resulting
in serious injury or even death.
To help make sure your airbag
systems are working properly
after a crash, have them
inspected and any necessary
replacements made as soon
as possible. If an airbag inflates, you will
need to replace airbag system
parts. See your dealer for service.
If the airbag readiness light stays
on after the vehicle is started or
comes on when you are driving,
the airbag system may not work
properly. Have the vehicle serviced
right away. See
Airbag Readiness
Light on page 5‑18 for more
information.

3-46 Seats and Restraints
Child Restraints
Older Children
Older children who have outgrown
booster seats should wear the
vehicle's safety belts.The manufacturer's instructions that
come with the booster seat state the
weight and height limitations for that
booster. Use a booster seat with a
lap-shoulder belt until the child
passes the fit test below:
.Sit all the way back on the seat.
Do the knees bend at the seat
edge? If yes, continue. If no,
return to the booster seat.
.Buckle the lap-shoulder belt.
Does the shoulder belt rest on
the shoulder? If yes, continue.
If no, try using the rear safety
belt comfort guide. See
“Rear
Safety Belt Comfort Guides”
under Lap-Shoulder Belt on
page 3‑21 for more information.
If the shoulder belt still does not
rest on the shoulder, then return
to the booster seat.
.Does the lap belt fit low and
snug on the hips, touching the
thighs? If yes, continue. If no,
return to the booster seat.
.Can proper safety belt fit be
maintained for the length of the
trip? If yes, continue. If no,
return to the booster seat.
Q: What is the proper way to wear safety belts?
A: An older child should wear a
lap-shoulder belt and get the
additional restraint a shoulder
belt can provide. The shoulder
belt should not cross the face or
neck. The lap belt should fit
snugly below the hips, just
touching the top of the thighs.
This applies belt force to the
child's pelvic bones in a crash.
It should never be worn over the
abdomen, which could cause
severe or even fatal internal
injuries in a crash.
Also see “Rear Safety Belt Comfort
Guides” underLap-Shoulder Belt on
page 3‑21.

Seats and Restraints 3-47
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.
In a crash, children who are not
buckled up can strike other people
who are buckled up, or can be
thrown out of the vehicle. Older
children need to use safety belts
properly.
{WARNING
Never do this.
Never allow two children to wear
the same safety belt. The safety
belt can not properly spread the
impact forces. In a crash, the
two children can be crushed
together and seriously injured.
A safety belt must be used by
only one person at a time.
{WARNING
Never do this.
Never allow a child to wear the
safety belt with the shoulder belt
behind their back. A child can be
seriously injured by not wearing
the lap-shoulder belt properly.
In a crash, the child would not be
restrained by the shoulder belt.
The child could move too far
forward increasing the chance of
head and neck injury.(Continued)
WARNING (Continued)
The child might also slide under
the lap belt. The belt force would
then be applied right on the
abdomen. That could cause
serious or fatal injuries. The
shoulder belt should go over the
shoulder and across the chest.

3-48 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.
