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).

1. OUTLINE OF THEFT DETERRENT SYSTEM
(a) When the theft deterrent system detects that the vehicle is being tampered with, the system sets off
the alarm, causing the horns to sound and the lights to light up or blink in order to alert people around
the vehicle to the theft.
(b) The theft deterrent system has an active arming mode; a disarmed state, an arming preparation state,
an armed state and an alarm sounding state.
(1) Disarmed state:

The alarm function is not operating.

The theft deterrent system is not operating.
(2) Arming preparation state:

The time until the system goes into the armed state.

The theft deterrent system is not operating.
(3) Armed state:

The theft deterrent system is operating.
HINT:
If the vehicle remains in a condition that sets off the alarm (any door remains open, engine hood remains
open, ignition switch remains directly connected) after the alarm ends, the alarm will be set off repeatedly
a maximum of 10 times for every one of the above specified conditions.
Alarm time: Approx. 27.5 sec. x 10
(4) Alarm sounding state:
When the theft deterrent system detects that the vehicle is being tampered with while in the
armed state, the system causes the horns to sound and the lights to light up or blink in order to
alert people around the vehicle to the theft.

When the theft deterrent system has entered into the alarm sounding state (tampering has been
detected) even once, the taillights will light up for 2 seconds if any of the following conditions is
present.

Switched to the disarmed state from the armed state.
5. SECURITY INDICATOR OUTPUT
