■There is a malfunction in the system
*1: The system judges a person of adult size as an adult. When a smalleradult sits in the front passenger seat, the system may not recognize him/
her as an adult 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: For some children, child in seat, child in booster seat or child in convertible
seat, the system may not recognize him/her as a child. Factors which may
affect this can be the physique or posture.
*5: Never install a rear-facing child restraint system on the front passengerseat. A forward-facing child restraint system should only be installed on the
front passenger seat when it is unavoidable. ( →P. 62)
*6: In case the indicator light is not illuminated, consult this manual on how to
install the child restraint system properly. ( →P. 58)

WARNING
■Front passenger occupant classi fication system precautions
Observe the following precautions regarding front passenger occupant clas-
sification 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 “A IR 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 (e.g.
seatback pocket).
● 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 fee\
t 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 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 acti-
vate 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.

WARNING
■Front passenger occupant classi fication system precautions
● 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. 58)
● 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 rear 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.
● Adjust the front passenger seat so that the head restraint does not touch
the ceiling. If the head restraint is left in contact with the ceiling, the system
may not detect the front passenger properly, leading to improper operation
of the airbags.

Exhaust gas precautions
Harmful substance to the human body is included in exhaust
gases if inhaled.
WARNING
Exhaust gases include harmful carbon monoxide (CO), which is colorless and
odorless. Observe the following precautions.
Failure to do so may cause exhaust gases enter the vehicle and may lead to
an accident caused by light-headedness, or may lead to death or a serious
health hazard.
■Important points while driving
● Keep the back door closed.
● If you smell exhaust gases in the vehicle even when the back door is
closed, open the side windows and have the vehicle inspected at your
Toyota dealer as soon as possible.
■ When parking
● If the vehicle is in a poorly ventilated area or a closed area, such as a
garage, stop the hybrid system.
● Do not leave the vehicle with the hybrid system on for a long time.
If such a situation cannot be avoided, park the vehicle in an open space
and ensure that exhaust fumes do not enter the vehicle interior.
● Do not leave the hybrid system operating in an area with snow build-up, or
where it is snowing. If snowbanks build up around the vehicle while the
hybrid system is operating, exhaust gases may collect and enter the vehi\
-
cle.
■ Exhaust pipe
The exhaust system needs to be checked periodically. If there is a hole or
crack caused by corrosion, damage to a joint or abnormal exhaust noise, be
sure to have the vehicle inspected and repaired by your Toyota dealer.
