4. Buckle, position and release the safety belt as
described inRear Seat Passengers on page 1-39.
Make sure that the shoulder belt crosses the
shoulder.
To remove and store the comfort guides, squeeze the
belt edges together so that you can take them out of the
guides. Make sure you remove the comfort guide
from the belt before you fold a rear seat down or use an
easy-entry seat, if your vehicle has one.
Safety Belt Extender
If the vehicle’s safety belt will fasten around you, you
should use it.
But if a safety belt isn’t long enough to fasten, your
dealer will order you an extender. It’s free. When you go
in to order it, take the heaviest coat you will wear, so
the extender will be long enough for you. The extender
will be just for you, and just for the seat in your
vehicle that you choose. Don’t let someone else use it,
and use it only for the seat it is made to t. To wear
it, just attach it to the regular safety belt.

{CAUTION:
Never do this.
Here two children are wearing the same belt.
The belt can’t properly spread the impact
forces. In a crash, the two children can be
crushed together and seriously injured. A belt
must be used by only one person at a time.
Q:What if a child is wearing a lap-shoulder belt,
but the child is so small that the shoulder belt
is very close to the child’s face or neck?
A:If the child is sitting in a rear seat outside position,
move the child toward the center of the vehicle. If
the child is sitting in the second row center
position, move the child toward the safety belt
buckle. In either case, be sure that the shoulder
belt still is on the child’s shoulder, so that in a
crash the child’s upper body would have the
restraint that belts provide. SeeRear Safety Belt
Comfort Guides for Children and Small Adults
on page 1-42. If the child is so small that the
shoulder belt is still very close to the child’s face
or neck, you might want to place the child a
seat that has a lap belt, if your vehicle has one.

Securing a Child Restraint Designed
for the LATCH System
1. Find the LATCH anchorages for the seating
position you want to use, where the bottom of the
seatback meets the back of the seat cushion.
2. Put the child restraint on the seat.
3. Attach and tighten the LATCH attachments on the
child restraint to the LATCH anchorages in the
vehicle. The child restraint instructions will show
you how.
4. If the child restraint is forward-facing, attach and
tighten the top tether to the top tether anchorage.
The child restraint instructions will show you
how. Also seeTop Strap on page 1-55.
5. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, simply unhook the top
tether from the top tether anchorage and then
disconnect the LATCH attachments from the LATCH
anchorages.

If your child restraint is equipped with the LATCH
system seeLower Anchorages and Top Tethers for
Children (LATCH System) on page 1-60. SeeTop Strap
on page 1-55if the child restraint has one.
There is no top strap anchor at the third row driver side
seating position. Do not secure a child seat in this
position if a national or local law requires that the top
strap be anchored or if the instructions that come
with the child restraint say that the top strap must be
anchored.
If your child restraint does not have the LATCH system,
you’ll be using the lap-shoulder belt to secure the child
restraint in this position. Be sure to follow the instructions
that came with the child restraint. Secure the child in the
child restraint when and as the instructions say.
1. Put the restraint on the seat.
2. 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.3. Buckle the belt. Make sure the release button is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.

Securing a Child Restraint in a
Center Rear Seat PositionIf your child restraint is equipped with the LATCH
system, seeLower Anchorages and Top Tethers for
Children (LATCH System) on page 1-60. SeeTop Strap
on page 1-55if the child restraint has one.
Second Row
The center seat position in the second row has a
lap-shoulder belt which works the same way as the
safety belt in the rear outside seat positions. For
instructions on how to secure a child restraint using a
lap-shoulder belt seeSecuring a Child Restraint in
a Rear Outside Seat Position on page 1-62.
Third Row
The center seat position in the third row has a lap belt.
Be sure to follow the instructions that came with the
child restraint. Secure the child in the child restraint
when and as the instructions say.

Securing a Child Restraint in the
Right Front Seat PositionYour vehicle has a right front passenger air bag. A rear
seat is a safer place to secure a forward-facing child
restraint. SeeWhere to Put the Restraint on page 1-54.
In addition, your vehicle may have the passenger
sensing system. The passenger sensing system is
designed to turn off the right front passenger’s frontal air
bag when an infant in a rear-facing infant seat or a
small child in a forward-facing child restraint or booster
seat is detected. SeePassenger Sensing System
on page 1-82andPassenger Air Bag Status Indicator
on page 3-43for more information on this including
important safety information.
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 air bag deploys.
1-68

{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s air bag inates. This is because
the back of the rear-facing child restraint
would be very close to the inating air bag.
Even though the passenger sensing system is
designed to turn off the passenger’s frontal air
bag if the system detects a rear-facing child
restraint, no system is fail-safe, and no one can
guarantee that an air bag will not deploy under
some unusual circumstance, even though it is
turned off. General Motors recommends that
rear-facing child restraints be secured in the
rear seat, even if the air bag is off.If you need to secure a forward-facing child restraint in
the right front seat position, move the seat as far
back as it will go before securing the forward-facing
child restraint. SeePower Seats on page 1-4orManual
Seats on page 1-3.
If your child restraint is equipped with the LATCH
system, seeLower Anchorages and Top Tethers for
Children (LATCH System) on page 1-60.
You will be using the lap-shoulder belt to secure the
child restraint in this position. SeeTop Strap on
page 1-55if your child restraint has one. Be sure to
follow the instructions that came with the child restraint.
Secure the child in the child restraint when and as
the instructions say.
1. Your vehicle has a right front passenger’s frontal air
bag. SeePassenger Sensing System on page 1-82.
General Motors recommends that rear-facing child
restraints be secured in a rear seat, even if the air
bag is off. If your child restraint is forward-facing,
move the seat as far back as it will go before
securing the child restraint in this seat. SeePower
Seats on page 1-4orManual Seats on page 1-3.
When the passenger sensing system has turned off
the right front passenger’s frontal air bag, the off
indicator in the passenger air bag status indicator
should light and stay lit when you turn the ignition to
RUN or START. SeePassenger Air Bag Status
Indicator on page 3-43.
1-69

{CAUTION:
Anyone who is up against, or very close to,
any air bag when it inates can be seriously
injured or killed. Air bags plus lap-shoulder
belts offer the best protection for adults, but
not for young children and infants. Neither the
vehicle’s safety belt system nor its air bag
system is designed for them. Young children
and infants need the protection that a child
restraint system can provide. Always secure
children properly in your vehicle. To read how,
see the part of this manual called “Older
Children” or “Infants and Young Children.”There is an air bag
readiness light on the
instrument panel cluster,
which shows the air
bag symbol.
The system checks the air bag electrical system for
malfunctions. The light tells you if there is an electrical
problem. SeeAir Bag Readiness Light on page 3-43
for more information.

Seat Position Sensors
Vehicles with dual stage air bags are also equipped with
special sensors which enable the sensing system to
monitor the position of both the driver and passenger
front seats. The seat position sensor provides
information which is used to determine if the air bags
should deploy at a reduced level or at full deployment.
Side Impact Air Bags
Your vehicle may or may not have a side impact air
bag. SeeAir Bag Systems on page 1-72. Side impact air
bags are designed to inate in moderate to severe
side crashes. A side impact air bag will inate if
the crash severity is above the system’s designed
“threshold level.” The threshold level can vary with
specic vehicle design. Side impact air bags are
not designed to inate in frontal or near-frontal impacts,
rollovers or rear impacts, because ination would not
help the occupant. A side impact air bag will only deploy
on the side of the vehicle that is struck.
Air Bag Systems
In any particular crash, no one can say whether an air
bag should have inated simply because of the damage
to a vehicle or because of what the repair costs were. For
frontal air bags, ination is determined by the angle of the
impact and how quickly the vehicle slows down in frontal
and near-frontal impacts. For side impact air bags,
ination is determined by the location and severity of the
impact.
The air bag system is designed to work properly under
a wide range of conditions, including off-road usage.
Observe safe driving speeds, especially on rough
terrain. As always, wear your safety belt. See Off-Road
Driving with Your Four-Wheel Drive Vehicle in the
Index for tips on off-road driving.

Passenger Sensing System
If your rearview mirror has one of the indicators pictured
in the following illustrations, your vehicle has a passenger
sensing system. The indicator will be visible when you
turn your ignition key to START or RUN. The words ON
and OFF or the symbol for on and off, will be visible on
the rearview mirror during the system check. When the
system check is complete, either the word ON or the word
OFF, or the symbol for on or the symbol for off will be
visible. SeePassenger Air Bag Status Indicator on
page 3-43. If your rearview mirror does not have either of
the indicators pictured, then your vehicle does not have
the passenger sensing system.The passenger sensing system will turn off the right
front passenger’s frontal air bag under certain
conditions. The driver’s air bag and the side air bags
are not part of the passenger sensing system.
The passenger sensing system works with sensors that
are part of the right front passenger’s seat and safety
belt. The sensors are designed to detect the presence of
a properly-seated occupant and determine if the
passenger’s frontal air bag should be enabled (may
inate) or not.
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
General Motors recommends that child restraints
be secured in a rear seat, including an infant riding in a
rear-facing infant seat, a child riding in a forward-facing
child seat and an older child riding in a booster seat.
Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. 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 air bag deploys. Passenger Air Bag Status Indicator – United States
