CAUTION:
If a wire harness which is too thin or some other thing is
used to tie down the side airbag assembly, it may be
snapped by the shock when the airbag is deployed. This is
highly dangerous. Always use a wire harness for vehicle
use which is at least 1.25 mm

(e) Place the tires.
(1) Place at least 2 tires under the tire to which the side
airbag assembly is tied.
(2) Place at least 2 tires over the tire to which the side
airbag assembly is tied. The top tire should have the
wheel installed.
(3) Tie the tires together with 2 wire harness.
CAUTION:
Make sure that the wire harness are tight. It is very danger-
ous when loose wire harness results in the tires coming
free due to the shock from the airbag deploying.
HINT:
Place the SST connector and wire harness inside tires. Secure
at least 1 m (3 ft) of slack for the wire harness.
(f) Install the SST.
Connect the connectors of the 2 SST to the side airbag
assembly connector.
SST 09082-00700, 09082-00750
NOTICE:
To avoid damaging the SST connector and wire harness,
do not lock the secondary lock of the twin lock. Also, se-
cure some slack for the SST wire harness inside the tire.
(g) Deploy the airbag.
(1) Connect the SST red clip to the battery positive (+)
terminal and the black clip to the battery negative
(-) terminal.
(2) Check that no one is within 10 m (33 ft) area around
the tire which the side airbag assembly is tied to.
(3) Press the SST activation switch and deploy the air-
bag.
HINT:
The airbag deploys simultaneously as the LED of the SST ac-
tivation switch lights up.
(h) Dispose of the side airbag assembly.
CAUTION:

The side airbag assembly is very hot when the airbag
is deployed, so leave it alone for at least 30 minutes
after deployment.

6. SRS WARNING LIGHT
The SRS warning light is located on the accessory meter. It
goes on to alert the driver of trouble in the system when a mal-
function is detected in the airbag sensor assembly self-diagno-
sis. In normal operation conditions when the ignition switch is
turned to the ACC or ON position, the light goes on for about 6
seconds and then goes off.
7. 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 airbag sensor assembly and door
side airbag assembly and judges whether the SRS must be ac-
tivated or not. The airbag sensor assembly cannot be disas-
sembled.
8. FRONT AIRBAG SENSOR
The front airbag sensor is mounted inside each of the side
members. The sensor unit is a mechanical type. When the sen-
sor detects deceleration force above a predetermined limit,
contact is made in the sensor, sending a signal to the airbag
sensor assembly. The front airbag sensor cannot be disas-
sembled.
9. SIDE AIRBAG SENSOR ASSEMBLY
The side airbag sensor assembly is mounted in the LH and RH
center pillars. The side airbag sensor assembly consists of a lat-
eral deceleration sensor, safing sensor, diagnosis circuit, etc.
It sends signals to the airbag sensor assembly to judge whether
the SRS side airbag must be activated or not. The side airbag
sensor assembly cannot be disassembled.

SRS AIRBAG
PRECAUTION
CAUTION:

The AVALON is equipped with SRS, which comprises a driver airbag, front passenger airbag
and side airbag. Failure to carry out service operations in the correct sequence could cause
the SRS to unexpectedly deploy during servicing, possibly leading to a serious accident. Fur-
ther, if a mistake is made in servicing the SRS, it is possible that the SRS may fail to operate
when required. Before performing servicing (including removal or installation of parts, inspec-
tion or replacement), be sure to read the following items carefully, then follow the correct proce-
dures described in the repair manual.

Work must be started 90 seconds after the ignition switch is turned to the ºLOCKº position and
the negative (-) terminal cable is disconnected from the battery.
(The SRS is equipped with a back-up power source so that if work is started within 90 seconds
from disconnecting the negative (-) terminal cable of the battery, the SRS may be deployed.)

Do not expose the steering wheel pad, front passenger airbag assembly, side airbag assembly,
airbag sensor assembly, front airbag sensor or side airbag sensor assembly directly to hot air
or flames.
NOTICE:

Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most impor-
tant source of information when troubleshooting. When troubleshooting the SRS, always in-
spect the DTCs before disconnecting the battery.

Even in cases of a minor collision where the SRS does not deploy, the steering wheel pad, front
passenger airbag assembly, side airbag assembly, airbag sensor assembly, front airbag sen-
sor and side airbag sensor assembly should be inspected.
(See page RS-15, RS-30, RS-44, RS-57, RS-64, RS-69, RS-74 and RS-79)

Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during
repairs.

Never use SRS parts from another vehicle. When replacing parts, replace them with new parts.

Never disassemble and repair the steering wheel pad, front passenger airbag assembly, side
airbag assembly, airbag sensor assembly, front airbag sensor or side airbag sensor assembly
in order to reuse it.

If the steering wheel pad, front passenger airbag assembly, side airbag assembly, airbag sen-
sor assembly, front airbag sensor or side airbag sensor assembly has been dropped, or if there
are cracks, dents or other defects in the case, bracket or connector, replace it with new one.

Use a volt/ohmmeter with high impedance (10 kW/V minimum) for troubleshooting the system's
electrical circuits.

Information labels are attached to the periphery of the SRS components. Follow the instruc-
tions on the notices.

After work on the SRS is completed, perform the SRS warning light check (See page DI-349).

When the negative (-) terminal cable is disconnected from the battery, the memory of the clock
and audio system will be canceled. So before starting work, make a record of the contents mem-
orized in the audio memory system. When work is finished, reset the audio systems as they
were before and adjust the clock. This vehicle has power seat which are all equipped with
memory function. However, it is not possible to make a record of the memory contents. So when
the work is finished, it will be necessary to explain this fact to the customer, and ask the custom-
er to adjust the features and reset the memory. To avoid erasing the memory in each memory
system, never use a back- up power supply from outside the vehicle.
