Several air bag system components get hot after inflation. Do not
touch them after inflation.
If the air bag has deployed,the air bag will not function
again and must be replaced immediately.If the air bag is not
replaced, the unrepaired area will increase the risk of injury in a
collision.
The SRS consists of:
•driver and passenger airbag modules (which include the inflators and
airbags).
•seat-mounted side airbags. Refer toSeat-mounted side airbag system
later in this chapter
•Safety Canopy™ system. Refer toSafety Canopy™ systemlater in
this chapter.
•one or more impact and safing sensors.
•a readiness light and tone.
•diagnostic module.
•and the electrical wiring which connects the components.
•Front passenger sensing system. Refer toFront passenger sensing
system.later in this chapter.
•“Passenger airbag off” or “pass airbag off” indicator lamp. Refer to
Front passenger sensing systemlater in this chapter.
The diagnostic module monitors its own internal circuits and the
supplemental airbag electrical system wiring (including the impact
sensors), the system wiring, the airbag system readiness light, the airbag
back up power and the airbag ignitors.
Front passenger sensing system
The front passenger sensing system is designed to meet the regulatory
requirements of Federal Motor Vehicle Safety Standard (FMVSS) 208
and is designed to disable (will not inflate) the front passenger’s frontal
airbag under certain conditions.
The front passenger sensing system works with sensors that are part of
the front passenger’s seat and safety belt. The sensors are designed to
detect the presence of a properly seated occupant and determine if the
front passenger’s frontal airbag should be enabled (may inflate) or
disabled (will not inflate).

The front passenger sensing system will disable (will not inflate) the
front passenger’s frontal airbag if:
•the front passenger seat is unoccupied, or has small/medium objects in
the front seat.
•the system determines that an infant is present in a rear-facing infant
seat that is installed according to the manufacturer’s instructions.
•the system determines that a small child is present in a forward-facing
child restraint that is installed according to the manufacturer’s
instructions.
•the system determines that a small child is present in a booster seat.
•
a front passenger takes his/her weight off of the seat for a period of time.
The front passenger sensing system will turn off the passenger seat side
airbag if:
•the seat is empty and safety belt is unbuckled.
The front passenger sensing system
uses apassenger airbag offor
pass airbag offindicator which will
illuminate and stay lit to remind you
that the front passenger frontal airbag is disabled. The indicator lamp is
located in the center stack of the instrument panel above the radio.
Note: The indicator lamp will illuminate for a short period of time when
the ignition is turned to the ON position to confirm it is functional.
When the front passenger seat is not occupied (empty seat) or in the
event that the front passenger frontal airbag is enabled (may inflate), the
indicator lamp will be unlit.
The front passenger sensing system is designed to disable (will not
inflate) the front passenger’s frontal airbag when a rear facing infant
seat, a forward-facing child restraint, or a booster seat is detected.
•
When the front passenger sensing system disables (will not inflate) the
front passenger frontal airbag, the indicator lamp will illuminate and stay
lit to remind you that the front passenger frontal airbag is disabled.
•If the child restraint has been installed and the indicator lamp is not
lit, then turn the vehicle off, remove the child restraint from the
vehicle and reinstall the restraint following the child restraint
manufacturer’s instructions.
The front passenger sensing system is designed to enable (may inflate)
the front passenger’s frontal airbag anytime the system senses that a
person of adult size is sitting properly in the front passenger seat.

•When the front passenger sensing system enables the front passenger
frontal airbag (may inflate), the indicator will be unlit and stay unlit.
If a person of adult size is sitting in the front passenger’s seat, but the
passenger airbag offorpass airbag offindicator lamp is lit, it is
possible that the person isn’t sitting properly in the seat. If this happens:
•Turn the vehicle off and ask the person to place the seatback in the
full upright position.
•Have the person sit upright in the seat, centered on the seat cushion,
with the person’s legs comfortably extended.
•Restart the vehicle and have the person remain in this position for
about two minutes. This will allow the system to detect that person
and enable the passenger’s frontal airbag.
•If the indicator lamp remains lit even after this, the person should be
advised to ride in the rear seat.

Adult Unlit Enabled
Even with Advanced Restraints Systems, children 12 and under
should be properly restrained in the back seat.
After all occupants have adjusted their seats and put on safety belts, it’s very
important that they continue to sit properly. A properly seated occupant sits
upright, leaning against the seat back, and centered on the seat cushion, with
their feet comfortably extended on the floor. Sitting improperly can increase
the chance of injury in a crash event. For example, if an occupant slouches,
lies down, turns sideways, sits forward, leans forward or sideways, or puts
one or both feet up, the chance of injury during a crash is greatly increased.
Sitting improperly out of position or with the seat back reclined
too far can take off weight from the seat cushion and affect the
decision of the front passenger sensing system, resulting in serious
injury or death in a crash.
Always sit upright against your seatback, with your feet on the floor.

The front passenger sensing system may detect small or medium objects
placed on the seat cushion. For most objects that are in the front
passenger seat, the passenger airbag will be disabled. Even though the
passenger airbag is disabled, thepass airbag offlamp may or may not
be illuminated according to the table below.

If you think that the status of the passenger airbag off indicator lamp is
incorrect, check for the following:
•Objects lodged underneath the seat
•Objects between the seat cushion and the center console (if
equipped)
•Objects hanging off the seat back
•Objects stowed in the seatback map pocket (if equipped)
•Objects placed on the occupant’s lap
•Cargo interference with the seat
•Other passengers pushing or pulling on the seat
•Rear passenger feet and knees resting or pushing on the seat
•Check to see if the clear objects by pass seat warning is displaying in
the message center. Refer tomessage centerin theDriver controls
chapter.
The conditions listed above may cause the weight of a properly seated
occupant to be incorrectly interpreted by the front passenger sensing
system. The person in the front passenger seat may appear heavier or
lighter due to the conditions described in the list above.

Do not attempt to service, repair, or modify the airbag SRS, its
fuses or the seat cover on a seat containing an airbag. See your
authorized dealer.
All occupants of the vehicle should always wear their safety belts
even when an airbag SRS is provided.
How does the side airbag system work?
The design and development of the side airbag system included
recommended testing procedures that were developed by a group of
automotive safety experts known as the Side Airbag Technical Working
Group. These recommended testing procedures help reduce the risk of
injuries related to the deployment of side airbags.
The side airbag system consists of
the following:
•An inflatable nylon bag (airbag)
with an inflator concealed behind
the outboard bolster of the driver
and front passenger seatbacks.
•A special seat cover designed to
allow airbag deployment.
•The same warning light,
electronic control and diagnostic
unit as used for the front airbags.
•Crash sensors located on the
front doors and C pillars (one
sensor on each pillar on each side
of the vehicle).
Side airbags, in combination with
safety belts, can help reduce the risk of severe injuries in the event of a
significant side impact collision.
The side airbags are fitted on the outboard side of the seatbacks of the
front seats. In certain lateral collisions, the airbag on the side affected by
the collision will be inflated. If the front passenger sensing system
detects an empty seat, the front passenger seat-mounted side airbag will
be deactivated. The airbag was designed to inflate between the door
panel and occupant to further enhance the protection provided
occupants in side impact collisions.

Do not attempt to service, repair, or modify the Safety Canopy™
system, its fuses, the A, B, or C pillar trim, or the headliner on a
vehicle containing a Safety Canopy™. See your authorized dealer.
All occupants of the vehicle including the driver should always
wear their safety belts even when an airbag SRS and Safety
Canopy™ system is provided.
To reduce risk of injury, do not obstruct or place objects in the
deployment path of the inflatable Safety Canopy™.
How does the Safety Canopy™ system work?
The design and development of the
Safety Canopy™ system included
recommended testing procedures
that were developed by a group of
automotive safety experts known as
the Side Airbag Technical Working
Group. These recommended testing
procedures help reduce the risk of
injuries related to the deployment of
side airbags (including the Safety
Canopy™).
The Safety Canopy™ system
consists of the following:
•An inflatable nylon curtain with
an inflator concealed behind the
headliner and above the doors
(one on each side of the vehicle).
•A headliner that will flex to open
above the side doors to allow Safety Canopy™ deployment.
•The same warning light, electronic control and diagnostic unit as used
for the front airbags.
•Two side crash sensors mounted at the front doors (one on each side
of the vehicle).
•Two side crash sensors located at the c-pillar behind the rear doors
(one on each side of the vehicle).

•Roll over sensor in the restraints control module (RCM).
The Safety Canopy™ system, in combination with safety belts, can help
reduce the risk of severe injuries in the event of a significant side impact
collision or rollover event.
Children 12 years old and under should always be properly restrained in
the second or third row seats (if equipped). The Safety Canopy™ will
not interfere with children restrained using a properly installed child or
booster seat because it is designed to inflate downward from the
headliner above the doors along the side window openings.
The Safety Canopy™ system is designed to activate when the vehicle
sustains lateral deceleration sufficient to cause the side crash sensor to
close an electrical circuit that initiates Safety Canopy™ inflation or when
a certain likelihood of a rollover event is detected by the rollover sensor.
The Safety Canopy™ is mounted to the roof side-rail sheet metal, behind
the headliner, above the first and second row seats. In certain lateral
collisions or rollover events, the Safety Canopy™ system will be
activated, regardless of which seats are occupied. The Safety Canopy™
is designed to inflate between the side window area and occupants to
further enhance protection provided in side impact collisions and rollover
events.
The fact that the Safety Canopy™ system did not activate in a collision
does not mean that something is wrong with the system. Rather, it
means the forces were not of the type sufficient to cause activation. The
Safety Canopy™ is designed to inflate in certain side impact collisions or
rollover events, not in rear impact, frontal or near-frontal collisions,
unless the collision causes sufficient lateral deceleration or rollover
likelihood.
Several Safety Canopy™ system components get hot after
inflation. Do not touch them after inflation.

SAFETY RESTRAINTS FOR CHILDREN
See the following sections for directions on how to properly use safety
restraints for children. Also seeAirbag supplemental restraint system
(SRS)in this chapter for special instructions about using airbags.
Important child restraint precautions
You are required by law to use safety restraints for children in the U.S.
and Canada. If small children (generally children who are four years old
or younger and who weigh 40 lb. [18 kg] or less) ride in your vehicle, you
must put them in safety seats made especially for children. Many states
require that children use approved booster seats until they are eight
years old. Check your local and state or provincial laws for specific
requirements regarding the safety of children in your vehicle. When
possible, always place children under age 12 in the rear seat of your
vehicle. Accident statistics suggest that children are safer when properly
restrained in the rear seating positions than in the front seating position.
Never let a passenger hold a child on his or her lap while the
vehicle is moving. The passenger cannot protect the child from
injury in a collision.
Always follow the instructions and warnings that come with any infant or
child restraint you might use.
Children and safety belts
If the child is the proper size, restrain the child in a safety seat. Children
who are too large for child safety seats (as specified by your child safety
seat manufacturer) should always wear safety belts.
Follow all the important safety restraint and airbag precautions that
apply to adult passengers in your vehicle.
If the shoulder belt portion of a combination lap and shoulder belt can be
positioned so it does not cross or rest in front of the child’s face or neck,
the child should wear the lap and shoulder belt. Moving the child closer to
the center of the vehicle may help provide a good shoulder belt fit.
Belt comfort guides are provided at the 2nd row outboard seats to
improve belt comfort for smaller occupants. The belt comfort guide is
not a substitute for a booster seat, and is only intended to improve the
comfort of the safety belt if it rests against the neck. Most children still
need a booster seat to encourage upright posture and improve lap belt
fit. Refer toSecond row comfort guideearlier in this chapter.
