The airbags inflate and deflate
rapidly upon activation. After airbag
deployment, it is normal to notice a
smoke-like, powdery residue or
smell the burnt propellant. This may
consist of cornstarch, talcum
powder (to lubricate the bag) or
sodium compounds (e.g., baking
soda) that result from the
combustion process that inflates the
airbag. Small amounts of sodium
hydroxide may be present which
may irritate the skin and eyes, but
none of the residue is toxic.
While the system is designed to help
reduce serious injuries, contact with
a deploying airbag may also cause abrasions, swelling or temporary
hearing loss. Because airbags must inflate rapidly and with considerable
force, there is the risk of death or serious injuries such as fractures,
facial and eye injuries or internal injuries, particularly to occupants who
are not properly restrained or are otherwise out of position at the time
of airbag deployment. Thus, it is extremely important that occupants be
properly restrained as far away from the airbag module as possible while
maintaining vehicle control.
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 belt pretensioners
•one or more impact and safing sensors

sensors), the system wiring, the airbag system readiness light, the airbag
back up power, the airbag ignitors and safety belt pretensioners.
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.
•a child or a small person occupies the front passenger seat and the
child or small person is unbuckled.
The front passenger sensing system
uses a
passenger airbag off
or

pass airbag off
indicator 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 lamp will be unlit and stay
unlit.

If a person of adult size is sitting in the front passenger’s seat, but the

passenger airbag off
or
pass airbag off
indicator 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.
OccupantPass Airbag Off

Empty seat Unlit Disabled
Small child in child
safety seat or boosterLit Disabled
Small child with safety
belt buckled or
unbuckledLit Disabled
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, the
pass airbag off
lamp 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
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 (including side air
curtain systems).
The side airbag system consists of
the following:
•An inflatable nylon bag (airbag)
with a gas generator concealed
behind the outboard bolster of
the driver and front passenger
seatbacks.
•The same warning light,
electronic control and diagnostic
unit as used for the front airbags.
•Two crash sensors located under the outboard side of the front seats,
attached near the floor.
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 or an unbuckled child or small person, 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.
The airbag SRS is designed to activate when the vehicle sustains lateral
deceleration sufficient to cause the sensors to close an electrical circuit
that initiates airbag inflation.

Side curtain airbag system
Do not place objects or
mount equipment on or
near the headliner at the siderail
that may come into contact with a
deploying side air curtain. Failure
to follow these instructions may
increase the risk of personal injury
in the event of a collision.
Do not place objects or mount equipment on or near the side air
curtain cover.
Do not lean your head on the door. The side airbag could injure
you as it deploys from the seat.
Do not attempt to service, repair, or modify the side air curtain
system, its fuses, the A, B, or C pillar trim, or the headliner on a
vehicle containing a side air curtain. See your authorized dealer.
All occupants of the vehicle, including the driver, should always
wear their safety belts even when an inflatable curtain is
provided.
To reduce the risk of injury, do not obstruct or place objects in
the deployment zone of the inflatable curtain.

How does the side air curtain system work?
The design and development of the
side air curtain 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 side air
curtain systems).
The side air curtain system consists
of the following:
•An inflatable nylon curtain with a
gas generator concealed behind
the headliner and above the
doors.
•The headliner will flex to open
above the side doors to allow air curtain deployment.
•The same warning light, electronic control and diagnostic unit as used
for the front airbags.
•Two crash sensors located under the outboard side of the front seats,
attached near the floor.
•Two crash sensors located at the base of the “C” pillars above the
wheel house.
Side air curtains and side airbags, in combination with safety belts, can
help reduce the risk of severe injuries in the event of a significant side
impact collision.
Children 12 years old and under should always be properly restrained in
the rear seats. The side air curtain 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 side air curtains are mounted to the sheet metal above the first and
second row seats. In certain lateral collisions, the air curtain and
seat-mounted side airbag on the side affected by the collision will be
inflated, except that the passenger sensing system will deactivate the
passenger seat-mounted side airbag if it detects an empty unbuckled
