PRECAUTIONS
Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"
Supplemental Restraint System (SRS) "AIR
BAG" and "SEAT BELT PRE-TENSIONER" NHEL0001
The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER" used along with
a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of GI
collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system
uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag,
depending on the severity of a collision and whether the front occupants are belted or unbelted. The SRS MA
system composition which is available to INFINITI I35 is as follows (The composition varies according to
optional equipment.):
