How The SRS Air Bags
Work
Your vehicle is equipped with the
following types of SRS air bags. SRS air
bags are designed to work together
with the seat belts to help to reduce
injuries during an accident. The SRS air
bags are designed to provide further
protection for passengers in addition to
the seat belt functions. Be sure to wear
seat belts properly.
Seat Belt Pretensioners
The seat belt pretensioners are
designed to deploy in moderate or
severe frontal, near frontal collisions. In
addition, during a side collision, the
pretensioner operates on the side in
which the collision occurs.
The pretensioners operate differently
depending on what types of air bags
are equipped. For details on the seat
belt pretensioner operation, refer to the
SRS Air Bag Deployment Criteria.Driver Air Bag
The driver's air bag is mounted in the
steering wheel.
When Air Bag crash sensors detect a
frontal impact of greater than moderate
force, the driver's Air Bag inflates
quickly helping to reduce injury mainly
to the driver's head or chest caused by
directly hitting the steering wheel. For
more details about Air Bag deployment,
refer to "SRS Air Bag Deployment
Criteria" in this chapter for further
information.
(With Passenger Occupant
Classification System)
The driver's dual-stage air bag controls
air bag inflation in two energy stages.
During an impact of moderate severity,
the driver's air bag deploys with lesser
energy, whereas during more severe
impacts, it deploys with more energy.Passenger Air Bag
(Dual stage)
The passenger Air Bag is mounted in
the passenger dashboard.
The inflation mechanism for the
passenger Air Bag is the same as the
driver's Air Bag, as mentioned above.
For more details about Air Bag
deployment, refer to "SRS Air Bag
Deployment Criteria" in this chapter.
For further details about air bag
deployment, refer to "SRS Air Bag
deployment criteria" in this chapter.
Side Air Bags
The side air bags are mounted in the
outer sides of the seat backs. When the
air bag crash sensors detect a side
impact of greater than moderate force,
the system inflates the side air bag only
on the side in which the vehicle was hit.

The side air bag inflates quickly to
reduce injury to the driver or
passenger's head and chest caused by
directly hitting interior parts such as a
door or window. For more details about
air bag deployment, refer to "SRS Air
Bag deployment criteria" in this chapter
for further information.
Warning!
Occupants, including children, who are
up against or very close to side air bags
can be seriously injured or killed.
Occupants, including children, should
never lean on or sleep against the door,
side windows, or area where the side air
bags inflate, even if they are in an infant or
child restraint.
Seat belts (and child restraints where
appropriate) are necessary for your
protection in all collisions. They also help
keep you in position, away from an inflating
side air bag. To get the best protection
from the side air bags, occupants must
wear their seat belts properly and sit
upright with their backs against the seats.
Children must be properly restrained in a
child restraint or booster seat that is
appropriate for the size of the child.
With Passenger Occupant
Classification System
In addition, the passenger side bag is
designed to only deploy when the
passenger occupant classification
sensor detects a passenger sitting on
the passenger's seat.
Warning!
If an occupant in the front passenger
seat is seated improperly, the occupant
may provide an output signal to the OCS
that is different from the occupant’s
properly seated weight input. This may
result in serious injury or death in a
collision.
Always wear your seat belt and sit
properly, with the seatback in an upright
position, your back against the seatback,
sitting upright, facing forward, in the center
of the seat, with your feet comfortably on
or near the floor.
Do not carry or hold any objects (e.g.,
backpacks, boxes, etc.) while seated in the
front passenger seat. Holding an object
may provide an output signal to the OCS
that is different than the occupant’s
properly seated weight input, which may
result in serious injury or death in a
collision.
Placing an object on the floor under the
front passenger seat may prevent the OCS
from working properly, which may result in
serious injury or death in a collision. Do not
place any objects on the floor under the
front passenger seat.

(*) In a side collision, the seat belt pretensioners and the side air bags deploy (only on the side in which the collision occurs).
(**)Passenger Occupant Classification System : the passenger front and side air bags and the seat belt pretensioner are
designed to deploy when the passenger occupant classification sensor detects a passenger sitting on the passenger's seat.
Note: In a frontal offset collision, the equipped air bags and pretensioners may all deploy depending on the direction, angle,
and rate of impact.

SAFETY

Warning!
Unapproved modifications or service
procedures to the passenger seat
assembly, its related components, seat
cover, or cushion may inadvertently change
the air bag deployment in case of a frontal
collision. This could result in death or
serious injury to the front passenger if the
vehicle is involved in a collision. A modified
vehicle may not comply with required
Federal Motor Vehicle Safety Standards
(FMVSS) and/or Canadian Motor Vehicle
Safety Standards (CMVSS).
If it is necessary to modify the air bag
system for persons with disabilities, contact
your authorized dealer.
Warning!
Deployed air bags and seat belt
pretensioners cannot protect you in
another collision. Have the air bags, seat
belt pretensioners, and the seat belt
retractor assemblies replaced by an
authorized dealer immediately. Also, have
the Occupant Restraint Controller System
serviced as well.
Warning!
Ignoring the Air Bag Warning Light in
your instrument panel could mean you
won’t have the air bags to protect you in a
collision. If the light does not come on as a
bulb check when the ignition is first turned
on, stays on after you start the vehicle, or if
it comes on as you drive, have an
authorized dealer service the air bag
system immediately.
Placing an object on the floor under the
front passenger seat may prevent the
occupant classification sensor from
working properly, which may result in
serious injury or death in a collision. Do not
place any objects on the floor under the
front passenger seat.
If there is a fault present in the occupant
classification sensor, both the Indicator
Light and the Air Bag Warning Light will
illuminate to show that the Passenger
Advanced Front Air Bag is deactivated.
Should this occur, the Passenger
Advanced Front Air Bag will remain
deactivated until the fault is cleared. This
indicates that you should take the vehicle
to an authorized dealer for service
immediately.
Limitations To SRS Air
Bag
In severe collisions such as those
described in "SRS Air Bag Deployment
Criteria" paragraph, the applicable SRS
air bag equipment will deploy.
However, in some accidents, the
equipment may not deploy depending
on the type of collision and its severity.
Limitations To Front / Near Front
Collision Detection
Front/near front collisions may not be
detected as severe enough to deploy
the SRS air bag equipment:
Impacts involving trees or poles A.
Frontal offset impact to the vehicle B.
Rear-ending or running under a
truck's tail gate.
141

Limitations To Side Collision
Detection
Side collisions may not be detected as
severe enough to deploy the SRS air
bag equipment:
Side impacts involving trees or poles
A.
Side impacts with two-wheeled
vehicles B.
Roll-over.
Passenger Occupant
Classification Sensor
Your vehicle is equipped with a
passenger occupant classification
sensor as a part of the supplementary
restraint system. This sensor is
equipped in the passenger's seat
cushion. This sensor measures the
electrostatic capacity of the
passenger's seat.
The SRS unit is designed to prevent the
passenger front and side Air Bags and
seat belt pretensioner system from
deploying if the passenger Air Bag
deactivation indicator light turns on.
To reduce the chance of injuries caused
by deployment of the passenger Air
Bag, the system deactivates the
passenger front and side Air Bags and
also the seat belt pretensioner system
when the passenger Air Bag
deactivation indicator light turns on.

SAFETY

This system shuts off the passenger
front and side Air Bags and seat belt
pretensioner system, so make sure the
passenger Air Bag deactivation
indicator light turns on.
The air bag/seat belt pretensioner
system warning light flashes and the
passenger Air Bag deactivation
indicator light illuminates if the sensors
have a possible malfunction. If this
happens, the passenger front and side
Air Bags and seat belt pretensioner
system will not deploy.
Note:If a passenger is seated as
shown in the following figure the
passenger occupant classification
sensor cannot detect a passenger
sitting on the passenger's seat correctly
and the deployment/non-deployment of
the Air Bags cannot be controlled as
indicated in the passenger Air Bag
deactivation indicator light on/off
condition chart.
Warning!
If a child restraint system, child, small
teenager or adult in the front passenger
seat is seated improperly, the occupant
may provide an output signal to the
occupant classification sensor that is
different from the occupant’s properly
seated weight input. This may result in
serious injury or death in a collision.
Passenger Air Bag Deactivation
Indicator Lights
These indicator lights turn on to remind
you that the passenger front and side
Air Bags and seat belt pretensioner will
or will not deploy during a collision. Note:
The system requires about
10 seconds to alternate between
turning the passenger front and side
Air Bags and seat belt pretensioner
system on or off.
The passenger air bag deactivation
indicator light may turn on repeatedly if
luggage or other items are put on the
passenger seat, or if the temperature
of the vehicle's interior changes
suddenly.
The passenger air bag deactivation
indicator light may turn on for
10 seconds if the electrostatic capacity
on the passenger seat changes.
The air bag/seat belt pretensioner
system warning light might turn on if
the passenger seat receives a severe
impact.
