3-30 Seats and Restraints
{WARNING
Airbags inflate with great force,
faster than the blink of an eye.
Anyone who is up against, or
very close to, any airbag when it
inflates can be seriously injured
or killed. Do not sit unnecessarily
close to any airbag, as you would
be if you were sitting on the edge
of the seat or leaning forward.
Safety belts help keep you in
position before and during a
crash. Always wear a safety belt,
even with airbags. The driver
should sit as far back as possible
while still maintaining control of
the vehicle.
Occupants should not lean on
or sleep against the door or side
windows in seating positions with
seat-mounted side impact airbags
and/or roof-rail airbags.
{WARNING
Children who are up against,
or very close to, any airbag
when it inflates can be seriously
injured or killed. Airbags plus
lap-shoulder belts offer protection
for adults and older children,
but not for young children and
infants. Neither the vehicle
safety belt system nor its airbag
system is designed for them.
Young children and infants
need the protection that a child
restraint system can provide.
Always secure children properly
in the vehicle. To read how, see
Older Children on page 3‑49or
Infants and Young Children on
page 3‑51.
There is an airbag readiness light
on the instrument panel cluster,
which shows the airbag symbol.
The system checks the airbag
electrical system for malfunctions.
The light tells you if there is an
electrical problem. See Airbag
Readiness Light on page 5‑20
for more information.

3-38 Seats and Restraints
This switch should only be turned
to the off position if the person in
the right front passenger position
is a member of a passenger risk
group identified by the national
government as follows:
Infant. An infant (less than
1 year old) must ride in the
front seat because:
.My vehicle has no rear seat;
.My vehicle has a rear seat
too small to accommodate a
rear-facing infant seat; or
.The infant has a medical
condition which, according to
the infant's physician, makes it
necessary for the infant to ride in
the front seat so that the driver
can constantly monitor the
child's condition.Child age 1 to 12. A child
age 1 to 12 must ride in the
front seat because:
.My vehicle has no rear seat;
.Although children ages 1 to 12
ride in the rear seat(s) whenever
possible, children ages 1 to 12
sometimes must ride in the front
because no space is available in
the rear seat(s) of my vehicle; or
.The child has a medical
condition which, according to
the child's physician, makes it
necessary for the child to ride in
the front seat so that the driver
can constantly monitor the
child's condition.
Medical Condition. A passenger
has a medical condition which,
according to his or her physician:
.Causes the passenger airbag
to pose a special risk for the
passenger; and
.Makes the potential harm from
the passenger airbag in a crash
greater than the potential harm
from turning off the airbag and
allowing the passenger, even if
belted, to hit the dashboard or
windshield in a crash.
{WARNING
If the right front passenger
airbag is turned off for a
person who is not in a risk
group identified by the national
government, that person
will not have the extra protection

The words ON and OFF, or the
symbol for on and off, will be visible
during the system check. If you
are using remote start to start the
vehicle from a distance, if equipped,
you may not see the system check. When the system check is
complete, either the word ON or
OFF, or the symbol for on or off, will
be visible. See
Passenger Airbag
Status Indicator on page 5‑23.
The passenger sensing system will
turn off the right front passenger
frontal airbag under certain
conditions. The driver airbag,
seat‐mounted side impact airbags
(if equipped), and the roof-rail
airbags (if equipped) are not
affected by the passenger
sensing system.
The passenger sensing system
works with sensors that are part
of the right front passenger seat
and safety belt. The sensors are designed to detect the presence
of a properly-seated occupant
and determine if the right front
passenger frontal airbag should
be enabled (may inflate) or not.
According to accident statistics,
children are safer when properly
secured in a rear seat in the correct
child restraint for their weight
and size.
We recommend that children 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.

3-42 Seats and Restraints
A label on the 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
(Continued)
WARNING (Continued)
system is fail-safe. No one can
guarantee that an airbag will
not deploy under some unusual
circumstance, even though the
airbag is turned off.
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.
If the vehicle does not have a
rear seat that will accommodate
a rear-facing child restraint, a
rear-facing child restraint should
not be installed in the vehicle,
even if the airbag is off. The passenger sensing system is
designed to turn off the right front
passenger frontal airbag if:.The right front passenger seat is
unoccupied.
.The system determines an infant
is present in a child restraint.
.A right front passenger takes
his/her weight off of the seat for
a period of time.
.Or, if there is a critical problem
with the airbag system or the
passenger sensing system.
When the passenger sensing
system has turned off the right front
passenger frontal airbag, the off
indicator will light and stay lit to
remind you that the airbag is off.
See Passenger Airbag Status
Indicator on page 5‑23.

The passenger sensing system is
designed to turn on (may inflate)
the right front passenger frontal
airbag anytime the system senses
that a person of adult size is
sitting properly in the right front
passenger seat.
When the passenger sensing
system has allowed the airbag to be
enabled, the on indicator will light
and stay lit to remind you that the
airbag is active.
For some children, including
children in child restraints, and for
very small adults, the passenger
sensing system may or may not
turn off the right front passenger
frontal airbag, depending upon the
person's seating posture and bodybuild. Everyone in your vehicle
who has outgrown child restraints
should wear a safety belt
properly
—whether or not there
is an airbag for that person.
{WARNING
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. See Airbag Readiness
Light on page 5‑20 for more
information, including important
safety information.
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 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
(Rear Seat Position) on
page 3‑66 orSecuring Child
Restraints (Right Front Seat
Position) on page 3‑69 or
Securing Child Restraints
(Center Front Seat Position) on
page 3‑78.

5. If, after reinstalling the childrestraint 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.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.
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 on
page 3‑46 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.

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. SeeAirbag Readiness Light
on page 5‑20 for more information.Child Restraints
Older Children
Older children who have outgrown
booster seats should wear the
vehicle 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.
