qFront Passenger Air Bag
The front passenger air bag is mounted in the front passenger dashboard.
The inflation mechanism for the front passenger air bag is the same as the driver's air bag,
as mentioned above. In addition, the front passenger air bag is designed to only deploy in
accordance with the total seated weight on the front passenger seat. For details, refer to the
driver and front passenger occupant classification system (page 2-55).
qSide Air Bags
The side air bags are mounted in the outboard sides of the front seatbacks.
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 front passenger's chest caused by
directly hitting interior parts such as a door or window. In addition, the front passenger side
air bag is designed to only deploy in accordance with the total seated weight on the front
passenger seat. For details, refer to the driver and front passenger occupant classification
system (page 2-55).

Driver and Front Passenger Occupant Classification System
First, please read“Supplemental Restraint System (SRS) Precautions”(page 2-43)
carefully.
qDriver Seat Slide Position Sensor
Your vehicle is equipped with a driver seat slide position sensor as a part of the
supplemental restraint system. The sensor is located under the driver seat. The sensor
determines whether the driver seat is fore or aft of a reference position and sends the seat
position to the diagnostic module (SAS unit). The SAS unit is designed to control the
deployment of the driver air bag depending on how close the driver seat is to the steering
wheel.
The air bag/front seat belt pretensioner system warning light flashes if the sensor has a
possible malfunction (page 2-50).
qFront Passenger Seat Weight Sensors
Your vehicle is equipped with a front passenger seat weight sensors as a part of the
supplemental restraint system. These sensors are located under both of the front passenger
seat rails. These sensors determine the total seated weight on the front passenger seat. The
SAS unit is designed to prevent the front passenger front and side air bags and seat belt
pretensioner system from deploying if the total seated weight is less than approximately 30
kg (66 lbs).
To reduce the chance of injuries caused by deployment of the front passenger air bag, the
system deactivates the front passenger front and side air bags and also the seat belt
pretensioner system when:
lThere is no passenger in the front passenger seat. (The front passenger air bag
deactivation indicator light does not illuminate.)
lThe total seated weight on the front passenger seat is less than approximately 30 kg (66
lbs). (The front passenger air bag deactivation indicator light illuminates.)
This system shuts off the front passenger front and side air bags and seat belt pretensioner
system, so make sure the front passenger air bag deactivation indicator light illuminates
according to the following table.
The air bag/front seat belt pretensioner system warning light flashes and the front
passenger air bag deactivation indicator light illuminates if the sensors have a possible
malfunction. If this happens, the front passenger front and side air bags and seat belt
pretensioner system will not deploy.

WARNING
Do not decrease the total seated weight on the front passenger seat:
When an adult or large child sits on the front passenger seat, decreasing the total
seated weight on the front passenger seat from the total seated weight of
approximately 42 kg (93 lbs) required for air bag deployment is dangerous. The front
passenger seat weight sensors will detect the reduced total seated weight condition
and the front passenger front and side air bags and seat belt pretensioner system
will not deploy during an accident. The front passenger will not have the
supplementary protection of the air bag, which could result in serious injury.
Decreasing the total seated weight on the front passenger seat from the total seated
weight of approximately 42 kg (93 lbs) could result in an air bag not deploying under
the following conditions, for example:
ØA rear passenger pushes up on the front passenger seat with their feet.
ØLuggage or other items placed under the front passenger seat or between the
front passenger seat and driver seat that push up the front passenger seat
bottom.
ØThe front passenger seat occupant sits in a manner that does not place the entire
weight of the occupant on the seat such as by sitting too close to the door,
grasping the assist grip or the rim of the moonroof and sitting with the seatback
reclined too far.
ØAny accessories which might decrease the total seated weight on the front
passenger seat are attached to the front passenger seat.
The front passenger front and side air bags and seat belt pretensioner systems will
deactivate if the total seated weight on the front passenger seat is close to 30 kg (66
lbs) and they will reactivate before the weight exceeds 42 kg (93 lbs).

Do not increase the total seated weight on the front passenger seat:
When an infant or small child sits on the front passenger seat, increasing the total
seated weight on the front passenger seat from the total seated weight of
approximately 30 kg (66 lbs) is dangerous. The front passenger seat weight sensors
will detect the increased total seated weight, which could result in the unexpected
deployment of the front passenger front and side air bags and seat belt pretensioner
system in an accident and may cause serious injury. Increasing the total seated
weight on the front passenger seat beyond the total seated weight of approximately
30 kg (66 lbs) could result in the front passenger front and side air bags and seat
belt pretensioner system deployment in an accident under the following conditions,
for example:
ØLuggage or other items are placed on the seat with the child in the child-restraint
system.
ØA rear passenger or luggage push or pull down on the front passenger seatback.
ØA rear passenger steps on the front passenger seat rails with their feet.
ØLuggage or other items are placed on the seatback or hung on the head restraint.
ØHeavy items are placed in the seatback map pocket.
ØThe seat is washed.
ØLiquids are spilled on the seat.
ØThe front passenger seat is moved backward, pushing into luggage or other items
placed behind it.
ØThe front passenger seatback contacts the rear seat.
ØLuggage or other items are placed between the front passenger seat and driver
seat.
ØAny accessories which might increase the total seated weight on the front
passenger seat are attached to the front passenger seat.
The front passenger front and side air bags and seat belt pretensioner systems will
deactivate if the total seated weight on the front passenger seat is close to 30 kg (66
lbs) and they will reactivate before the weight exceeds 42 kg (93 lbs).
CAUTION
ØTo assure proper deployment of the front air bag and to prevent damage to the
sensors in the front seat bottoms:
ØDo not place sharp objects on the front seat bottoms or leave heavy luggage on
them.
ØDo not spill any liquids on the front seats or under the front seats.
ØTo allow the sensors to function properly, always perform the following:
ØAdjust the front seats as far back as possible and always sit upright against the
seatbacks with seat belts worn properly.
ØIf you place your child on the front passenger seat, secure the child-restraint
system properly and slide the front passenger seat as far back as possible (page
2-36).
