impact that exceeds the set threshold level (the level of force corresponding
to the impact force produced by an approximately 3300 lb. [1500 kg] vehicle
colliding with the vehicle cabin from a direction perpendicular to the vehicle
orientation at an approximate speed of 12 - 18 mph [20 - 30 km/ h]).

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 .

could cause death or serious injury in the event of a collision .
● Do not apply a heavy load to the front passenger seat or equipm ent (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 passeng er seat.

Safety information for children
●It is recommended that children sit in the rear seats to avoid acci-
dental contact with 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. 135, 167)
● Do not let small children operate equipment which may catch or
pinch body parts, such as the power window, hood, trunk, seats,
etc.
Observe the following precautions when children are in the vehi -
cle.
Use a child restraint system app ropriate 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 p laying with
the windows or other features of the vehicle. In addition, heat build-up or

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 sto ps, a child
must be properly restrained, using a seat belt or child restrai nt system
depending on the age and size of the child.
● Toyota strongly urges the use of a proper child restraint syste m that con-
forms to the size of the child, installed on the rear seat. According to acci-
dent 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.
● Place one child to a child restraint system and then secure the child with
the harness of the child restraint system.
■ 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 ev en if it is
not in use. Do not store the child restraint system unsecured in 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 trunk.
