Seat belt height adjustment
ETD in installation position
If the seat belt is also equipped with a seat belt force limiter, the limiter, when activated,
helps to reduce the peak force exerted by the seat belt on the occupant. The seat belt
force limiter is also designed to work with a deploying front air bag by providing more
even distribution of occupant restraining forces between the seat belt and air bag.
The ETD is designed to be activated only if the seat
belt is fastened and the vehicle’s ignition is on, during
a frontal or rear-end collision generating a frontal
deceleration or rear acceleration rate sufficient to meet
the system’s deployment threshold. ETDs in vehicles
equipped with rollover sensors will also deploy during
a lateral rollover if the sensor determines that
potential additional protection can be provided.
In vehicles equipped with an occupant sensor for the
front passenger seat, the ETD will only be activated if
the sensor detects an occupant in the seat or if the seat
belt is fastened.
The driver-side ETD will only be activated if the belt is fastened. To operate at the speed
necessary to increase belt effectiveness in an accident, the ETD is operated
pyrotechnically and may thus release some harmless smoke into the passenger
compartment. Upon activation of the ETD, the SRS indicator lamp comes on or a
diagnostic code is stored in the SRS control unit.
