Infiniti I30 (A33). Manual — part 565
SRS Configuration
=NHRS0010
SRS901
The air bag deploys if the diagnosis sensor unit activates while the ignition switch is in the “ON” or “START”
position.
The collision modes for which supplemental restraint systems are activated are different among the SRS sys-
tems. For example, the driver air bag module and passenger air bag module are activated in a frontal colli-
sion but not in a side collision.
SRS configurations which are activated for some collision modes are as follows;

Left side collision

Seat Belt Pre-tensioner with Load Limiter
=NHRS0034
The seat belt pre-tensioner system with load limiter is installed to
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 fron-
tal 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.
