1-7. Safety information
GX460_CANADA (OM60F29U)
*1: The system judges a person of adult size as an adult. When a smalleradult 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 large 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 and posture.
*4: Never install a rear-facing child restraint system on the front passen- ger seat. A forward-facing child restraint system should only be
installed on the front passenger seat when it is unavoidable.
(→ P. 1 5 2 )
*5: In case the indicator light is not illuminated, consult this manual on
how to installing the child restraint system properly. ( →P. 147)
CAUTION
■Front passenger occupant classification system precautions
Observe the following precautions regarding the front passenger occupant classifi-

CAUTION
■Front passenger occupant classification system precautions
●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 illuminated, the front passenger airbag
and front passenger knee airbag may not activate correctly, 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 (e.g. seat-
back pocket).
●Do not put weight on the front passenger seat by putting your hands or feet on
the front passenger seat seatback from the second seat.
●Do not let a second seat 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.
●Do not recline the front passenger seatback so far that it touches a second seat.
This may cause the “AIR BAG OFF” indicator light to be illuminated, which indi-
cates that the passenger’s airbags will not deploy in the event of a severe acci-
dent. If the seatback touches the second seat, return the seatback to a position
where it does not touch the second seat. Keep the front passenger seatback as
upright as possible when the vehicle is moving. Reclining the seatback exces-
sively may lessen the effectiveness of the seat belt system.

CAUTION
■Front passenger occupant classification system precautions
●If an adult sits in the front passenger seat, the “AIR BAG ON” indicator light is illu-
iminated. 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 cor-
rectly. If the “AIR BAG OFF” indicator still remain illuminated, either ask the pas-
senger 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 passenger seat
in the proper order. (→P. 1 5 2 )
●Do not modify or remove the front seat.
●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 in the detection sys-
tem. In this case, contact your Lexus 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 covers the
seat cushion surface.
●Do not modify or replace the upholstery of the front seat.
