Driver and Passenger Occupant Classification System
First, please read“Supplemental Restraint System (SRS) Precautions ”(page 2-28)
carefully.
q Driver 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/seat belt pretensioner system warning light flashes if the sensor has a possible
malfunction (page 2-35).
qPassenger Seat Weight Sensors
Your vehicle is equipped with a passenger seat weight sensors as a part of the supplemental
restraint system. These sensors are located under both of the passenger seat rails. These
sensors determine the total seated weight on the passenger seat. The SAS unit is designed
to prevent the 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 passenger air bag, the system
deactivates the passenger front and side air bags and also the seat belt pretensioner system
when:
lThere is no passenger in the passenger seat. (The passenger air bag deactivation
indicator light does not illuminate.)
lThe total seated weight on the passenger seat is less than approximately 30 kg (66 lbs).
(The passenger air bag deactivation indicator light illuminates.)
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 illuminates
according to the following table.
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.

WARNING
Do not decrease the total seated weight on the passenger seat:When an adult or large child sits on the passenger seat, decreasing the total seated
weight on the passenger seat from the total seated weight of approximately 42 kg
(93 lbs) required for air bag deployment is dangerous. The passenger seat weight
sensors will detect the reduced total seated weight condition and the passenger front
and side air bags and seat belt pretensioner system will not deploy during an
accident. The passenger will not have the supplementary protection of the air bag,
which could result in serious injury. Decreasing the total seated weight on the
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:
ØLuggage or other items placed under the passenger seat or between the passenger
seat and center console that push up the passenger seat bottom.
Ø The passenger seat occupant sits in a manner such that the occupant's entire
weight is not placed on the seat sitting too close to the door.
Ø Any accessories which might decrease the total seated weight on the passenger
seat are attached to the passenger seat.
The passenger front and side air bags and seat belt pretensioner systems will
deactivate if the total seated weight on the 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 passenger seat:When an infant or small child sits on the passenger seat, increasing the total seated
weight on the passenger seat from the total seated weight of approximately 30 kg
(66 lbs) is dangerous. The passenger seat weight sensors will detect the increased
total seated weight, which could result in the unexpected deployment of the
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 passenger
seat beyond the total seated weight of approximately 30 kg (66 lbs) could result in
the passenger front and side air bags and seat belt pretensioner system deployment
in an accident under the following conditions, for example:
ØThe total seated weight of the child with the child-restraint system on the
passenger seat is approximately 30 kg (66 lbs) or more.
Ø Luggage or other items are placed on the seat with the child in the child-restraint
system.
Ø The seat is washed.
Ø Liquids are spilled on the seat.
Ø The passenger seat is moved backward, and it is pushed into luggage or other
items placed behind it.
Ø Luggage or other items are placed between the passenger seat and center
console.
Ø Any accessories which might increase the total seated weight on the passenger
seat are attached to the passenger seat.
The passenger front and side air bags and seat belt pretensioner systems will
deactivate if the total seated weight on the passenger seat is close to 30 kg (66 lbs)
and they will reactivate before the weight exceeds 42 kg (93 lbs).
CAUTION
Ø To assure proper deployment of the front air bag and to prevent damage to the
sensors in the seat bottoms:
ØDo not place sharp objects on the seat bottoms or leave heavy luggage on
them.
ØDo not spill any liquids on the seats or under the seats.
Ø To allow the sensors to function properly, always perform the following:
ØAdjust the 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 passenger seat, secure the child-restraint system
properly and slide the passenger seat as far back as possible.
