Your vehicle is equipped with a front passenger occupant classification system. This system detects the conditions of the right front passenger seat and activates or deactivates the devices for the front passenger.
1. SRS warning light
2. Front passenger’s seat belt reminder light
3. AIR BAG OFF indicator light
4. AIR BAG ON indicator light
Conditions and operation of the front passenger occupant classification system
■ Adult*1
■ Child*3 or child restraint system*4
■ Unoccupied
■ There is a malfunction in the system
*1: The system judges a person of adult size as an adult. When a smaller adult sits in the front passenger seat, the system may recognize him/her as a child depending on his/her physique and posture.
*2: In the event the front passenger does not wear a seat belt.
*3: When a larger child who has outgrown a child restraint system sits in the front passenger seat, the system may recognize him/ her as an adult depending on his/her physique or posture.
*4: Never install a rear-facing child restraint system on the front passenger seat. A forward-facing child restraint system should only be installed on the front passenger seat when it is unavoidable.
*5: In case the indicator is not illuminated, consult this manual for installing the child restraint system properly.
CAUTION
■Front passenger occupant classification system precautions
Observe the following precautions regarding front passenger occupant classification system.
Failure to do so may cause death or serious injury.
●Wear the seat belt properly.
●Make sure the front passenger’s seat belt tab has not been left inserted into the buckle before someone sits in the front passenger seat.
●Make sure the AIR BAG OFF indicator light is not illuminated when using the seat belt extender for the front passenger seat. If the AIR BAG OFF indicator light is illuminated, disconnect the extender tongue from the seat belt buckle, then reconnect the seat belt. Reconnect the seat belt extender after making sure the AIR BAG ON indicator light is illuminated. If you use the seat belt extender while the AIR BAG OFF indicator light is illuminated, the SRS airbags for the passenger may not activate correctly, which could cause death or serious injury in the event of collision.
●Do not place a heavy load on the front passenger seat or equipment (e.g.
seatback table).
●Do not apply pressure to the front passenger seat by resting hands or legs on the seatback.
●Do not let a rear passenger lift the front passenger seat with their feet or press on the seatback with their legs.
●Do not put objects under the front passenger seat.
CAUTION
■Front passenger occupant classification system precautions
●Do not recline the front passenger seatback so far that it touches a rear seat or a back wall. This may cause the AIR BAG OFF indicator light to be illuminated, which indicates that the passenger’s airbags will not deploy in the event of a severe accident. If the seatback touches the rear seat or back wall, return the seatback to a position where it does not touch the rear seat or back wall. Keep the front passenger seatback as upright as possible when the vehicle is moving. Reclining the seatback excessively may lessen the effectiveness of the seat belt system.
●If an adult sits in the front passenger seat, the AIR BAG ON indicator light is illuminated. If the AIR BAG OFF indicator is illuminated, ask the passenger to sit up straight, well back in the seat, feet on the floor, and with the seat belt worn correctly. If the AIR BAG OFF indicator still remains illuminated, either ask the passenger to move to the rear seat, or if that is not possible, move the front passenger seat fully rearward.
●When it is unavoidable to install the forward-facing child restraint system on the front passenger seat, install the child restraint system on the front passenger seat in the proper order.
●Do not modify or remove the front seats.
●Do not kick the front passenger seat or subject it to severe impact. Otherwise, the SRS warning light may come on to indicate a malfunction of the detection system. In this case, contact your Toyota dealer immediately.
●Child restraint systems installed on the rear seat should not contact the front seatbacks.
●Do not use a seat accessory, such as a cushion or seat cover, that covers the seat cushion surface.
●Access Cab and Double Cab models: Do not attach a commercial seatback table or other heavy item to the back of the front passenger seat.
●Do not modify or replace the upholstery of the front seat.
