SRS (Supplemental Restraint System) Airbag System

A newly developed SRS knee airbag is standard equipment for the driver's seat on the new
Avensis.

The SRS knee airbag is positioned in the lower part of the instrument pa\
nel on the driver's side
to receive the impact of the driver's lower body when he or she shifts forward in the event of
a frontal collision, contributing to prevention of secondary impact to t\
he lower body.

Dual-stage SRS airbags are standard equipment for the driver and front p\
assenger seats. In
the event of a severe frontal collision, the airbags function with the s\
eat belts to help reduce
the impact on the driver's and front passenger's head and chest. The seat position sensor is
adopted only for the driver's seat to help the driver side SRS airbag deploy at the right moment.

SRS side airbags (driver / front passenger seats) which help ease side\
impacts, are standard
equipment.

SRS curtain shield airbags (front/rear seats) that help ease side impa\
cts are standard
equipment for all models except 1AZ-FE engine models. They are available as an op\
tion for
1AZ-FE engine models.

(1)When the torque wrench is combined with SST oran extension tool to extend the length, and you
tighten until the torque wrench reads the specified
torque value, the actual torque becomes excessive.
(2)In this manual, only the specified torque is de-
scribed. In case of using SST or extension tool, cal-
culate the reading of the torque wrench by the fol-
lowing formula.

2.FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND SEAT BELT PRETENSIONER
HINT:
The AVENSIS is equipped with an SRS (Supplemental Restraint System), which \
includes the driver airbag,
front passenger airbag and seat belt pretensioner.
Failure to carry out the service operations in the correct sequence could cause\
the supplemental restraint
system to unexpectedly deploy while servicing. This could cause a seriou\
s accident.
Furthermore, if a mistake is made when servicing the supplemental restra\
int system, it is possible that the
SRS will fail to operate when required. Before servicing (including remova\
l or installation of parts, inspection
or replacement), be sure to read the following items carefully. Then follow the correct procedures described
in this manual.
(a)GENERAL NOTICE (1)Malfunction symptoms of the supplemental restraint system are difficult to confirm so the diag-nostic trouble codes become the most important source of information when trou\
bleshooting.
When troubleshooting the supplemental restraint system, always check the dia\
gnostic trouble
codes before disconnecting the battery (See page 05±1184).
(2) Work must be started after 90 seconds from the time that the ignition switch\
is turned to the LOCK position and the negative (±) terminal cable is disconnected from the batte\
ry.
(The supplemental restraint system is equipped with a back±up power sourc\
e. So, if work is
started within 90 seconds after disconnecting the negative (±) terminal ca\
ble from the battery,
the SRS may deploy).
When the negative (±) terminal cable is disconnected from the battery, memory of the clock and
audio systems is cancelled. So, before starting work, make a record of the contents recorded
in each memory system. Then, when work is finished, reset the clock and audio systems as be-
fore.

(3)Even in the case of a minor collision where the SRS does not deploy, the horn button assembly, instrument panel passenger airbag assembly and seat belt pretensioner should be in\
spected
(See pages 60±19, 60±19 and 61±9).
(4)Never use the SRS related parts from another vehicle. When replacing the part\
s, replace them with new parts.
(5)Before repairs, remove the airbag sensor if there is a possibility of sh\
ock during repairs.
(6)Never disassemble and repair the center airbag sensor assembly, side airbag sensor assembly, horn button assembly, instrument panel passenger airbag assembly, front seat airbag assembly,
curtain shield airbag assembly or seat belt pretensioner.
(7)If the center airbag sensor assembly, the side airbag sensor assembly, the horn button assembly, the instrument panel passenger airbag assembly have been dropped, or if the\
re are cracks,
dents or other defects in the case, bracket or connector, replace them with new ones.
(8)Do not directly expose the airbag sensor assembly, the side airbag sensor assembly, the horn button assembly, the instrument panel passenger airbag assembly or the seat belt pretensioner
to hot air or flames.
(9)Use a volt/ohmmeter with high impedance (10 k
/V minimum) for troubleshooting electrical cir-
cuits.
(10)Information labels are attached to the SRS components. Follow the instru\
ctions on the notices.
(11)After work on the supplemental restraint system is completed, check the SRS w\
arning light (See page 05±1184)
(b)SPIRAL CABLE (in Combination Switch)(1)The steering wheel must be fitted correctly to thesteering column with the spiral cable at the neutral
position, otherwise cable disconnection and other
troubles may occur. Refer to page 60±26 of this
manual concerning the correct installation of the
steering wheel.
(c) HORN BUTTON ASSEMBLY (with Airbag) (1) When removing the horn button assembly or handling a new horn button, it sho\
uld be placed withthe top of the pad surface facing upward. Placing it with the pad surface facing downward may
lead to a serious accident if the airbag deploys for some reasons. Also, do \
not place anything
on top of the horn button.
(2) Never measure the resistance of the airbag squib (This may cause the airbag to inflate, which is very dangerous).
(3) Grease should not be applied to the horn button assembly, and the pad should not be cleaned with any type of detergent.
(4) Store the horn button assembly where the ambient temperature remains below 93
C (200
F),
without high humidity and away from electrical noise.
(5) When using electric welding, disconnect the airbag connector (4 yellow pins\
) under the steering column near the combination switch connector before starting work.

(6)When disposing the vehicle or the horn button assembly alone, the airbag\
should be inflated us-
ing an SST before disposal (See page 60±19).
Perform the operation in a safe place away from electrical noise.
(d)INSTRUMENT PANEL PASSENGER AIRBAG ASSEMBLY (1)Always place a removed or new instrument panel passenger airbag assembly\
with the airbaginflation direction facing upward. Placing the airbag assembly with the airbag inflation direction
facing downward could cause a serious accident if the airbag deploys.
(2)Never measure the resistance of the airbag squib (This may cause the airbag to inflate, which is very dangerous).
(3)Grease should not be applied to the instrument panel passenger airbag assembly\
and the airbag door should not be cleaned with detergents of any kind.
(4)Store the airbag assembly where the ambient temperature remains below 93
C (200
F), without
high humidity and away from electrical noise.
(5)When using electric welding, disconnect the airbag connector (4 yellow pins\
) installed on the as- sembly before starting work.
(6)When disposing of a vehicle or the airbag assembly unit, the airbag should be deployed using\
SST before disposal (See page 60±30).
Activate in a safe place away from electrical noise.
