■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
● 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.

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.
