(2) Move the SST(s) to at least 10 m (33 ft) away from
the horn button assy tied down to the disc wheel.
(e) Cover the horn button assy with a cardboard box or tires.

Covering method using a cardboard box:
Cover the horn button assy with the cardboard box
and weigh the cardboard box down in 4 places with
at least 190 N (20 kg, 44 lb).
Size of cardboard box:
Must exceed the following dimensions:
X = 460 mm (18.11 in.)
Y = 650 mm (25.59 in.)
NOTICE:

When the dimension Y of the cardboard box exceeds
the diameter of the disc wheel with tire to which the
horn button assy is tied, X should be the following
size.
X = 460 mm (18.11 in.) + width of tire

If a cardboard box smaller than the specified size is
used, the cardboard box will be broken by the shock
from the airbag deployment.

Covering method using tires:
Place at least 3 tires with no disc wheels on top of
the tire with disc wheel to which the horn button assy
is tied.
Tire size: Must exceed the following dimensions
Width: 185 mm (7.28 in.)
Inner diameter: 360 mm (14.17 in.)
CAUTION:
Do not use tires with disc wheels.
NOTICE:

The tires may be marked by the airbag deployment,
so use a redundant tires.

Do not place the SST(s) connector under the tire be-
cause the SST(s) connector could be damaged.

PRECAUTION
CAUTION:

AVENSIS is equipped with SRS, which comprises of a driver airbag, front passeng\
er airbag,
side airbag, curtain shield airbag and driver knee airbag. Failure to carry \
out service operations
in the correct sequence could cause the SRS to unexpectedly deploy during \
servicing, possibly
leading to serious accident. Further, if a mistake is made in servicing the SRS, it is possible that
the SRS may fail to operate when required. Before performing servicing (in\
cluding removal or
installation of parts, inspection or replacement), be sure to read the \
following items carefully,
then follow the correct procedures indicated in the repair manual.

Work must be started 90 seconds after the ignition switch is turned to the º\
LOCKº 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 wi\
thin 90 seconds
after disconnecting the negative (±) terminal cable of the battery, the SRS may be deployed.)

Do not expose the horn button assy, instrument panel passenger airbag assy, instrument panel
airbag assy, airbag sensor assy center, airbag front sensor, front seat airbag assy, side airbag
sensor assy, curtain shield airbag assy, airbag sensor rear or seat position airbag sensor di-
rectly to hot air or flames.
NOTICE:

Malfunction symptoms of the SRS are difficult to confirm, so DTCs are th\
e most important in-
formation source of information when troubleshooting. When troubleshooting the SRS, always
inspect DTCs before disconnecting the battery.

Even in the case of a minor collision when the SRS does not deploy, the horn button assy, instru-
ment panel passenger airbag assy, instrument panel airbag assy, airbag sensor assy center,
airbag front sensor, front seat airbag assy, side airbag sensor assy, curtain shield airbag assy,
airbag sensor rear and seat position sensor must be inspected (See page 60±11).

Before repairs work, remove the airbag sensor if any kind of shock is likely to occur to the sen-
sor during operation.

Never use SRS parts from another vehicle. When replacing the parts, repl\
ace them with new
ones.

Never disassemble nor repair the horn button assy, instrument panel passenger airbag assy,
instrument panel airbag assy, airbag sensor assy center, airbag front sensor, front seat airbag
assy, side airbag sensor assy, curtain shield airbag assy, airbag sensor rear or seat position
airbag sensor in order to reuse it.

If the horn button assy, instrument panel passenger airbag assy, instrument panel airbag assy,
airbag sensor assy center, airbag front sensor, front seat airbag assy, side airbag sensor assy,
curtain shield airbag assy, airbag sensor rear or seat position airbag sensor has been dropped,
or if there are any cracks, dents or other defects in the case, bracket \
or connector, replace it
with a new one.

Use a volt/ohmmeter with high impedance (10 k
/V minimum) for troubleshooting the electrical
circuits circuits.

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

After work on the SRS is completed, perform the SRS warning light check \
(See page 05±1184).

(5) Connector lock mechanism:
Locking the connector lock button connects the
connector securely.
(b) When the vehicle is involved in a frontal collision in the
hatched area (Fig. 1) and the shock is larger than the pre-
determined level, the SRS is activated automatically. The
safing sensor is designed to go on at a smaller decelera-
tion rate than the airbag sensor. As illustrated in the Fig.
2, ignition is caused when current flows to the squib,
which happens when the safing sensor and the decelera-
tion sensor go on simultaneously. When a deceleration
force acts on the sensors, 3 squibs in the driver airbag,
front passenger airbag and knee airbag ignite and gener-
ate gas. The gas discharging into the driver airbag, front
passenger airbag and knee airbag rapidly increases the
pressure inside the bags, breaking the horn button assy
and instrument panel. The inflation of the bag then ends,
and the bags deflate as the gas is discharged through dis-
charge holes at the bag's rear or side.
