System DescriptionNHS0007Y
Pre-crash seat belt system is adapted to front seat belts RH/LH.
When the pre-crash seat belt control unit judges the emergency braking operation, it gives the sense of
security by the motor built into the pre-crash seat belt retracting the shoulder belt and suppressing the
crew's posture change. Also, it eases the damage of the collision.

Preliminary CheckNHS00086
PRE-CRASH SEAT BELT OPERATION INSPECTION
WAR NING :
The following tests should be performed in a safe, open place that is free of traffic and obstacles.
The tests should be performed on a dry, paved road. Do not attempt the tests on wet or unpaved
road, open road, or highway. (This may cause an accident or personal injury.)
Driver and passenger assume it will not operate and prepare themselves accordingly.
1. Tighten driver and passenger seat belts.
2. Drive at approximately 25 km/h (16 MPH).
3. Notify passenger of a sudden stop. Driver and passenger prepare themselves for the possibility of
system not operating. Then, driver fully depresses the brake pedal to stop suddenly.
4. Make sure that the shoulder of the seat belt is pulled while braking.
