PRECAUTIONS

PRECAUTION A
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT LU
PRE-TENSIONER" INFOID:0000000001728584
The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along C
with 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
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. D
Information necessary to service the system safely is included in the SR and SB section of this Service Man-
ual.
