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.
(P. 53)
*5: In case the indicator light is not illuminated, consult this manual on how
to install the child restraint system properly. (P. 57)
*6: In the event of a side collision.
*7: In the event of a frontal collision or vehicle rollover.

CAUTION
■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. 57)
●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
detection 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.
