4. SIDE AIRBAG ASSEMBLY
The inflator and bag of the SRS are stored in the side airbag as-
sembly and cannot be disassembled. The inflator contains a
squib, igniter charge and gas generator, etc., and inflates the
bag when instructed by the airbag sensor assembly. The side
airbag assembly cannot be disassembled.
5. CURTAIN SHIELD AIRBAG ASSEMBLY
The inflator and bag of the SRS are stored in the curtain shield
airbag assembly and cannot be disassembled. The inflator con-
tains a squib, igniter charge, gas generator, etc., and inflates
the bag when instructed by the airbag sensor assembly. The
curtain shield airbag assembly cannot be disassembled.
6. SEAT BELT PRETENSIONER
The front seat outer belt has the seat belt pretensioner system.
The pretensioner operates in the event of a frontal collision. The
seat belt pretensioner cannot be disassembled.
7. SRS WARNING LIGHT
The SRS warning light is located on the combination meter. It
comes on to alert the driver of trouble in the system when a mal-
function is detected in the airbag sensor assembly. In normal
operation conditions when the ignition switch is turned to the
ON position, the light comes on for approximately 6 seconds
and then goes off.
8. AIRBAG SENSOR ASSEMBLY
The airbag sensor assembly is mounted on the floor inside the
lower center finish panel. The airbag sensor assembly consists
of an airbag sensor, safing sensor, diagnosis circuit, ignition
control, drive circuit, etc. It receives signals from the airbag sen-
sor, front airbag sensor, side and curtain shield airbag sensor
and curtain shield airbag sensor, and judges whether the SRS
must be activated or not. The airbag sensor assembly cannot
be disassembled.

DISPOSAL
HINT:
When scrapping vehicle equipped with a SRS or disposing of
a front seat outer belt (with seat belt pretensioner), always first
deploy the airbag in accordance with the procedure given in RS
section or activate the seat belt pretensioner. If any abnormality
occurs with the airbag deployment or seat belt pretensioner ac-

eration out±of±door and where it will not create a nui-
sance to nearby residents.

When activating the seat belt pretensioner, always
use the specified SST. (SRS Airbag Deployment Tool)
Perform the operation in a place away from electrical
noise.
