Toyota Yaris: Seat Belt Pretensioner and Load Limiting Systems / Pretensioners

Toyota Yaris XP210 (2020-2026) Owner's Manual / Essential Safety Equipment / Seat Belt Systems / 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.

Seat Belt Pretensioner and Load Limiting Systems

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...

Load limiter

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...
