SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
Revision: 2007 April2007 M35/M45
Front Seat Belt Pre-Tensioner with Load LimiterNHS0008T
The seat belt pre-tensioner system with load limiter is installed for
both the driver's seat and the front passenger's seat. It operates
simultaneously with the SRS air bag system in the event of a frontal
collision with an impact exceeding a specified level.
When the frontal collision with an impact exceeding a specified level
occurs, seat belt slack resulting from clothing or other factors is
immediately taken up by the pre-tensioner. Vehicle passengers are
securely restrained.
When passengers in a vehicle are thrown forward in a collision and
the restraining force of the seat belt exceeds a specified level, the
load limiter permits the specified extension of the seat belt by the
twisting of the ELR shaft, and a relaxation of the chest-area seat belt
web tension while maintaining force.

Front side air bag is built-in type.
The front seatback with built-in type side air bag have the labels as
shown.
