Black plate (59,1)
If your vehicle is also equipped with a driver and front passenger occupant
classification system, refer to the Driver and Front Passenger Occupant Classification
System (page 2-57) for details.
If your vehicle is equipped with a driver and front passenger occupant classification
system, the front passenger air bag deactivation indicator light illuminates for a specified
time after the ignition is switched ON.
Small children must be protected by a child-restraint system as stipulated by law in every
state and province. In certain states and provinces, larger children must use a child-restraint
system (page 2-26).
Carefully consider which child-restraint system is necessary for your child and follow the
installation directions in this Owner's Manual as well as the child-restraint system
manufacturer's instructions.
WARNING
Seat belts must be worn in air bag equipped vehicles:Depending only on the air bags for protection during an accident is dangerous.
Alone, air bags may not prevent serious injuries. The appropriate air bags can be
expected to inflate only in the first accident, such as frontal, near frontal, side
collisions that are at least moderate. Vehicle occupants should always wear seat
belts.
Children should not ride in the front passenger seat: Placing a child, 12 years or under, in the front seat is dangerous. The child could be
hit by a deploying air bag and be seriously injured or even killed. Even if the front
passenger air bag deactivation indicator light illuminates, always move the front
passenger seat as far back as possible. A sleeping child is more likely to lean against
the door and be hit by the side air bag in a moderate collision to the front-passenger
side of the vehicle. Whenever possible, always secure a child 12 years and under on
the rear seat with an appropriate child-restraint system for the child's age and size.

First, please read“Supplemental Restraint System (SRS) Precautions ”(page 2-44)
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/front seat belt pretensioner system warning light flashes if the sensor has a
possible malfunction (page 2-53).
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 and
monitor the seat belt buckle for 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 front passenger air bag deactivation indicator light illuminates.
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 the front passenger air bag deactivation indicator light
illuminates. Refer to the following table for the front passenger air bag deactivation
indicator light illumination conditions.
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 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 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.
Ø Luggage 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.
Ø The 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.
Ø Any 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 front passenger air bag deactivation indicator light illuminates.
