■Emergency locking retractor (ELR)
The retractor will lock the belt during a sudden stop or on imp act. It may also
lock if you lean forward too quickly. A slow, easy motion will allow the belt to
extend so that you can move around fully.
■ Automatic locking retractor (ALR)
When a passenger’s shoulder belt is completely extended and then retracted
even slightly, the belt is locked in that position and cannot be extended. This
feature is used to hold the child restraint system (CRS) firmly . To free the belt
again, fully retract the belt and then pull the belt out once m ore. (P. 62)
■ Child seat belt usage
The seat belts of your vehicle were principally designed for persons of adult
size.
●Use a child restraint system appropriate for the child, until the child
becomes large enough to properly wear the vehicle’s seat belt. ( P. 58)
● When the child becomes large enough to properly wear the vehicle’s seat
belt, follow the instructions regarding seat belt usage. ( P. 30)
■ Replacing the belt after the pr etensioner has been activated
If the vehicle is involved in multiple collisions, the pretensi oner will activate for
the first collision, but will not activate for the second or su bsequent collisions.
■ Seat belt extender
If your seat belts cannot be fastened
securely because they are not long
enough, a personalized seat belt extender
is available from your Toyota dealer free
of charge.

WARNING
Observe the following precautions to reduce the risk of injury in the event of
sudden braking, sudden swerving or an accident.
Failing to do so may cause death or severe injury.
■ Wearing a seat belt
● Ensure that all passengers wear a seat belt.
● Always wear a seat belt properly.
● Each seat belt should be used by one person only. Do not use a seat belt
for more than one person at once, including children.
● Toyota recommends that children be seated in the rear seat and always
use a seat belt and/or an appropriate child restraint system.
● To achieve a proper seating position, do not recline the seat m ore than
necessary. The seat belt is most effective when the occupants a re sitting
up straight and well back in the seats.
● Do not wear the shoulder belt under your arm.
● Always wear your seat belt low and snug across your hips.
● Always wear the belt with the shoulder portion over the outside armrest
and the lap portion under the outside armrest.
■ Pregnant women
■ People suffering illness
Obtain medical advice and wear the seat belt in the proper way. (P. 30)
Obtain medical advice and wear the seat
belt in the proper way. ( P. 30)
Women who are pregnant should posi-
tion the lap belt as low as possible over
the hips in the same manner as other
occupants, extending the shoulder belt
completely over the shoulder and avoid-
ing belt contact with the rounding of the
abdominal area.
If the seat belt is not worn properly, not
only a pregnant woman, but also the
fetus could suffer death or serious injury
as a result of sudden braking or a colli-
sion.

WARNING
■When children are in the vehicle
Do not allow children to play with the seat belt. If the seat belt becomes
twisted around a child’s neck, it may lead to choking or other serious injuries
that could result in death.
If this occurs and the buckle cannot be unfastened, scissors sh ould be used
to cut the belt.
■ Seat belt pretensi oners (front seats)
● Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which prevents t he sensor
from detecting the passenger’s weight properly. As a result, th e seat belt
pretensioner for the front passenger’s seat may not activate in the event of
a collision.
● If the pretensioner has activated, the SRS warning light will c ome on. In
that case, the seat belt cannot be used again and must be replaced at
your Toyota dealer.
■ Adjustable shoulder anchor (front and second outside Tip-up sea ts)
Always make sure the shoulder belt is positioned across the cen ter of your
shoulder. The belt should be kept away from your neck, but not falling off
your shoulder. Failure to do so could reduce the amount of prot ection in an
accident and cause death or serious injuries in the event of a sudden stop,
sudden swerve or accident. ( P. 33)
■ Seat belt damage and wear
● Do not damage the seat belts by allowing the belt, plate, or bu ckle to be
jammed in the door.
● Inspect the seat belt system periodically. Check for cuts, fray ing, and loose
parts. Do not use a damaged seat belt until it is replaced. Dam aged seat
belts cannot protect an occupant from death or serious injury.
● Ensure that the belt and plate are locked and the belt is not twisted.
If the seat belt does not function correctly, immediately conta ct your Toyota
dealer.
● Replace the seat assembly, including the belts, if your vehicle has been
involved in a serious accident, even if there is no obvious dam age.
● Do not attempt to install, remove, modify, disassemble or dispo se of the
seat belts. Have any necessary repairs carried out by your Toyota dealer.
Inappropriate handling may lead to incorrect operation.

WARNING
■Using a seat belt extender
● Do not wear the seat belt extender if you can fasten the seat belt without
the extender.
● Do not use the seat belt extender when installing a child restr aint system
because the belt will not securely hold the child restraint system, increas-
ing the risk of death or serious injury in the event of an acci dent.
● The personalized extender may not be safe on another vehicle, when
used by another person, or at a different seating position othe r than the
one originally intended.
■ When using the third center seat belt
NOTICE
■When using a seat belt extender
When releasing the seat belt, press on the buckle release butto n on the
extender, not on the seat belt.
This helps prevent damage to the vehicle interior and the extender itself.
Do not use the third center seat belt with
either buckle released. Fastening only
one of the buckles may result in death or
serious injury in case of sudden braking,
sudden swerving or an accident.
