Rear Safety Belt Comfort Guides
for Children and Small Adults
Rear seat comfort guides provide added safety belt
comfort for older children who have outgrown booster
seats and for small adults. When installed on a shoulder
belt, the comfort guide better positions the belt away
from the neck and head.There is one guide for each outside passenger in the
rear seat. Here's how to install a comfort guide and use
the safety belt:
1. Remove the guide from its storage clip on the
interior body.
2. Place the guide over the belt and insert the
two edges of the belt into the slots of the guide.

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.
Child Restraints
Older Children
Older children who have outgrown booster seats should
wear the vehicle's safety belts.
If you have the choice, a child should sit in a seat that
has a lap-shoulder belt to get the additional restraint
a shoulder belt can provide.

A forward-facing child seat (C-E) provides restraint for
the child's body with the harness and also sometimes
with surfaces such as T-shaped or shelf-like shields.A booster seat (F-G) is a child restraint designed to
improve the ®t of the vehicle's safety belt system. Some
booster seats have a shoulder belt positioner, and
some high-back booster seats have a ®ve-point harness.
A booster seat can also help a child to see out the
window.

Never put a rear facing child restraint in the right front
passenger's seat unless the air bag is off. Here is why:
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger's air bag in¯ates. This is because
the back of the rear-facing child restraint
would be very close to the in¯ating air bag.
Be sure the air bag is off before using a
rear-facing child restraint in the right front seat
position. If you secure a forward-facing child
restraint in the right front seat, always move
the right front passenger seat as far back as it
will go.
A rear seat is a safer place to secure a forward facing
child restraint. See
Where to Put the Restraint on
page 1-39. 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 a
forward-facing child restraint. See
Power Seats on
page 1-3.
{CAUTION:
If the air bag readiness light in the instrument
panel cluster ever comes on when you have
turned off the air bag, it means that something
may be wrong with the air bag system. The
right front passenger's air bag could in¯ate
even though the switch is off. If this ever
happens, have the vehicle serviced promptly.
Until you have the vehicle serviced, do not let
anyone whom the national government has
identi®ed as a member of a passenger air bag
risk group sit in the right front passenger's
position (for example, do not secure a
rear-facing child restraint in the right front
passenger's seat). See ªAir Bag Off Switchº in
the Index.

1. Your vehicle has a right front passenger's frontal air
bag. SeeAir Bag Off Switch on page 1-68andPassenger Sensing System on page 1-73. If your
child restraint is forward-facing, move the seat as far
back as it will go before securing the restraint in
this seat. See
Power Seats on page 1-3. If you need
to use a rear-facing child restraint in this seat,
make sure the air bag is off once the child restraint
has been installed.
When the passenger sensing system or the air bag
off switch 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. See
Passenger Air Bag Status Indicator on page 3-33.
2. Find the LATCH anchorages where the bottom of
the seatback meets the back of the cushion.
3. Put the child restraint on the seat.
4. 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.
5. 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 see
Top Strap on page 1-40.6. Push and pull the child restraint in different
directions to be sure it is secure.
7. If your vehicle has the passenger sensing system
and the air bag is off, the off indicator will be lit and
stay lit in the inside rearview mirror when the key
is turned to RUN or START. Never put a rear-facing
child restraint in the right front passenger seat
unless the air bag is off.
If a child restraint has been installed and the on
indicator is lit, turn the vehicle off. Remove the child
restraint from the vehicle and reinstall the restraint.
If after reinstalling the child restraint and restarting the
vehicle, the on indicator is still lit, check to make
sure that the vehicle's seatback is not pressing the child
restraint into the seat cushion. If this happens, slightly
recline the vehicle's seatback and adjust the seat
cushion if possible. Also make sure the child restraint is
not trapped under the vehicle head restraint. If this
happens, adjust the head restraint.
If the on indicator is still lit, use the air bag off switch to
turn off the air bag or secure the child in the child
restraint in a rear seat position in the vehicle if one is
available and check with your dealer. See
Air Bag
Off Switch on page 1-68for more on this, including
important safety information.

In addition to the air bag off switch, 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 or small
child in a rear-facing infant seat, a forward-facing
child restraint, or a booster seat is detected. In addition
to the passenger sensing system, you may use the
air bag off switch located on the instrument panel to turn
the air bag off. See
Air Bag Off Switch on page 1-68andPassenger Sensing System on page 1-73.Never put a rear facing child restraint in the right front
passenger's seat unless the air bag is off. Here is why:
{CAUTION:

If your child restraint is equipped with the LATCH
system, see
Lower Anchorages and Top Tethers for
Children (LATCH System) on page 1-44. SeeTop Strap
on page 1-40if your child restraint has one.If your child restraint does not have the LATCH system,
you will 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.

Seat Position Sensors
Vehicle's 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 depoyment.
What Makes an Air Bag In¯ate?
In an impact of sufficient severity, the air bag sensing
system detects that the vehicle is in a crash. The
sensing system triggers a release of gas from the
in¯ator, which in¯ates the air bag. The in¯ator, air bag,
and related hardware are all part of the air bag
modules inside the steering wheel and in the instrument
panel in front of the right front passenger.
How Does an Air Bag Restrain?
In moderate to severe frontal or near-frontal collisions,
even belted occupants can contact the steering wheel or
the instrument panel. Air bags supplement the
protection provided by safety belts. Air bags distribute
the force of the impact more evenly over the occupant's
upper body, stopping the occupant more gradually.But air bags would not help you in many types of
collisions, including rollovers, rear impacts and many
side impacts, primarily because an occupant's motion is
not toward those air bags. Air bags should never be
regarded as anything more than a supplement to safety
belts, and then only in moderate to severe frontal or
near-frontal collisions.
What Will You See After an Air Bag
In¯ates?
After an air bag in¯ates, it quickly de¯ates, so quickly
that some people may not even realize the air bag
in¯ated. Some components of the air bag module ± the
steering wheel hub for the driver's air bag, or the
instrument panel for the right front passenger's
bag ± will be hot for a short time. The parts of the bag
that come into contact with you may be warm, but
not too hot to touch. There will be some smoke and dust
coming from the vents in the de¯ated air bags. Air
bag in¯ation does not prevent the driver from seeing or
being able to steer the vehicle, nor does it stop
people from leaving the vehicle.

Q:Because I have a disability, I have to get my
vehicle modi®ed. How can I ®nd out whether
this will affect my advanced air bag system?
A:Changing or moving any parts of the front seats,
safety belts, the air bag sensing and diagnostic
module (located under the driver's seat), or
the inside rearview mirror can affect the operation
of the advanced air bag system. If you have
questions, call Customer Assistance. The phone
numbers and addresses for Customer Assistance
are in Step Two of the Customer Satisfaction
Procedure in this manual. See
Customer
Satisfaction Procedure on page 7-2
.
Restraint System Check
Checking Your Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt
is torn or frayed, get a new one right away.
Also look for any opened or broken air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)
