PRECAUTIONS
Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"
Supplemental Restraint System (SRS) "AIR
BAG" and "SEAT BELT PRE-TENSIONER" NHBR0001
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
collision. The SRS system composition which is available to NISSAN MODEL A33 is as follows (The compo-
sition varies according to optional equipment.):
