*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 is wearing a seat belt.  
*3: In the event the front passenger does not wear a seat belt.  
*4: 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.  
*5: 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.  
(P. 55)  
*6: In case the indicator light is not illuminated, consult this manual on how  
to install the child restraint system properly. (P. 59)  
*7: In the event of a side collision.  
*8: In the event of a frontal collision or rollover.

WARNING  
Front passenger occupant classification system precautions  
Observe the following precautions regarding the 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 plate 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, and 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 illumi-  
nated, the SRS airbags for the front passenger will not activate, which  
could cause death or serious injury in the event of a collision.  
Do not apply a heavy load to the front passenger seat or equipment.  
Do not put weight on the front passenger seat by putting your hands or  
feet on the front passenger seat seatback from the rear passenger seat.  
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.

WARNING  
Front passenger occupant classification system precautions  
Do not recline the front passenger seatback so far that it touches a rear  
seat. This may cause the “AIR BAG OFF” indicator light to be illuminated,  
which indicates that the SRS airbags for the front passenger will not  
deploy in the event of a severe accident. If the seatback touches the rear  
seat, return the seatback to a position where it does not touch the rear  
seat. 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 a forward-facing child restraint system on  
the front passenger seat, install the child restraint system on the front pas-  
senger seat in the proper order. (P. 59)  
Do not modify or remove the front seats.  
Do not kick the front passenger seat or subject it to severe impact. Other-  
wise, the SRS warning light may come on to indicate a malfunction of the  
front passenger occupant classification system. In this case, contact your  
Toyota dealer immediately.  
Child restraint systems installed on the second seat should not contact the  
front seatbacks.  
Do not use a seat accessory, such as a cushion and seat cover, that cov-  
ers the seat cushion surface.  
Do not modify or replace the upholstery of the front seat.
