PRECAUTIONS
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"
Precautions for 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 GI
a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types
of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS sys-
tem uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air MA
bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information that is necessary to service the system safely is included in the RS section of this Service Manual.
