The pretensioners help the seat belts to quickly restrain the occupants by retracting the seat belts when the vehicle is subjected to certain types of severe frontal or side collision or a vehicle rollover.

The pretensioners do not activate in the event of a minor frontal impact, a minor side impact or a rear impact.
Emergency locking retractor (elr)
The retractor will lock the belt during a sudden stop or on impact. 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 more.
Child seat belt usage
The seat belts of your vehicle were principally designed for persons of adult size.
Replacing the belt after the pretensioner has been activated
If the vehicle is involved in multiple collisions, the pretensioner will activate for the first collision, but will not activate for the second or subsequent 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.
Caution
Observe the following precautions to reduce the risk of injury in the event of sudden braking, sudden swerving or an accident.
Failure to do so may cause death or serious injury.
Wearing a seat belt
Pregnant women
Obtain medical advice and wear the seat belt in the proper way.
Women who are pregnant should position 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 avoiding belt contact with the rounding of the abdominal area.
If the seat belt is not worn properly, not
only the pregnant woman, but also the
fetus could suffer death or serious injury
as a result of sudden braking or a collision.

People suffering illness
Obtain medical advice and wear the seat belt in the proper way.
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 should be used to cut the belt.
Seat belt pretensioners
Doing so will disperse the passenger’s weight, which prevents the sensor from detecting the passenger’s weight properly. As a result, the seat belt pretensioner for the front passenger’s seat may not activate in the event of a collision.
Adjustable shoulder anchor
Always make sure the shoulder belt is positioned across the center 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 protection in an accident and cause death or serious injuries in the event of a sudden stop, sudden swerve or accident.
Seat belt damage and wear
If the seat belt does not function correctly, immediately contact your toyota dealer.
Inappropriate handling of the pretensioner may prevent it from operating properly resulting in death or serious injury.
Using a seat belt extender
When using the rear center seat belt
Do not use the rear 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
or a collision. 
Notice
When using a seat belt extender
When releasing the seat belt, press on the buckle release button on the extender, not on the seat belt.
This helps prevent damage to the vehicle interior and the extender itself.
