■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 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 chi ld 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 passenger seat. A forward-facing child restraint system should only be in stalled on the
front passenger seat when it is unavoidable. ( P. 60)
*6: In case the indicator light is not illuminated, consult this m anual on how to
install the child restraint system properly. ( P. 56)

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 le ft 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 “AI R 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 (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 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 rear
seat. This may cause the “AIR BAG OFF” indicator light to be il luminated,
which indicates that the SRS airbags for the front passenger wi ll 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 lesse n the
effectiveness of the seat belt system.

WARNING
■Front passenger occupant classification 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 illumin ated, 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” indicat or still
remains illuminated, either ask the passenger to move to the re ar seat, or
if that is not possible, move the front passenger seat fully re arward.
● 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. 56)
● Do not modify or remove the front seats.
● Do not kick the front passenger seat or subject it to severe im pact. 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 imprope r 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 do or 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 t ime.
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 w hile 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.

Riding with children
●It is recommended that children sit in the rear seats to avoid acci-
dental contact wit h the shift lever, wiper switch etc.
● Use the rear door child-protector lock or the window lock switc h to
avoid children opening the door while driving or operating the
power window accidentally. ( P. 184, 212)
● Do not let small children operate equipment which may catch or
pinch body parts, such as the power window, hood, back door,
seats etc.
Observe the following precautions when children are in the vehi -
cle.
Use a child restraint system appropriate for the child, until the
child becomes large enough to properly wear the vehicle’s seat
belt.
WARNING
Never leave children unattended in the vehicle, and never allow children to
have or use the key.
Children may be able to start the vehicle or shift the vehicle into neutral.
There is also a danger that children may injure themselves by playing with
the side windows, the moon roof (if equipped) or other features of the vehi-
cle. In addition, heat build-up or extremely cold temperatures inside the
vehicle can be fatal to children.

WARNING
■When a child is riding
Observe the following precautions.
Failure to do so may result in death or serious injury.
● For effective protection in automobile accidents and sudden stops, a child
must be properly restrained, using a seat belt or child restrai nt system
which is correctly installed. For installation details, refer t o the operation
manual enclosed with the child restraint system. General installation
instructions are provided in this manual.
● Toyota strongly urges the use of a proper child restraint system that con-
forms to the weight and size of the child, installed on the rea r seat. Accord-
ing to accident statistics, the child is safer when properly restrained in the
rear seat than in the front seat.
● Holding a child in your or someone else’s arms is not a substit ute for a
child restraint system. In an accident, the child can be crushed against the
windshield or between the holder and the interior of the vehicle.
■ Handling the child restraint system
If the child restraint system is not properly fixed in place, t he child or other
passengers may be seriously injured or even killed in the event of sudden
braking, sudden swerving, or an accident.
● If the vehicle were to receive a strong impact from an accident , etc., it is
possible that the child restraint system has damage that is not readily visi-
ble. In such cases, do not reuse the restraint system.
● Make sure you have complied with all installation instructions provided
with the child restraint system manufacturer and that the syste m is prop-
erly secured.
● Keep the child restraint system properly secured on the seat even if it is
not in use. Do not store the child restraint system unsecured i n the pas-
senger compartment.
● If it is necessary to detach the child restraint system, remove it from the
vehicle or store it securely in the luggage compartment.
