Toyota Yaris: Seat Belt Pretensioner and Load Limiting Systems / Pretensioners
When a collision is detected, the pretensioners deploy simultaneously with
the air bags.
The pretensioners deploy simultaneously with the air bags when a
roll-over is also detected.
For deployment details, refer to the SRS Air Bag Deployment Criteria.
The front seat belt retractors remove slack quickly as the air bags
are expanding. Any time the air bags and seat belt pretensioners
have fired they must be replaced.
A system malfunction or operation conditions are indicated by a
warning.
Refer to Warning/Indicator Lights.
Refer to Air Bag/Front Seat Belt Pretensioner System Warning
Beep.
In addition, the pretensioner system for the front passenger, like the
front and side passenger air bag, is designed to only deploy when
the front passenger occupant classification sensor detects a passenger sitting
on the front passenger’s seat.
For details, refer to the front passenger occupant classification sensor.
For optimum protection, the driver and front passenger seat
belts are equipped with pretensioner and load limiting systems.
For both these systems to work properly you must wear the seat
belt properly...
The load limiting system releases belt webbing in a controlled manner to
reduce belt force on the occupant’s chest. While the most
severe load on a seat belt occurs in frontal collisions, the load limiter has an
automatic mechanical function and can activate in any
accident mode with sufficient occupant movement...
