Use gloves and safety glasses when handling a front
passenger airbag assembly with deployed airbag.

Always wash your hands with water after completing
the operation.

Do not apply water, etc. to a front passenger airbag
assembly with deployed airbag.

When scrapping a vehicle, deploy the airbag and
scrap the vehicle with the front passenger airbag as-
sembly still installed.

When moving a vehicle for scrapping which has a
front passenger airbag assembly with deployed air-
bag, use gloves and safety glasses.
HINT:
The airbag deploys as the LED of the SST activation switch
comes on.
2. DEPLOYMENT WHEN DISPOSING OF FRONT PAS-
SENGER AIRBAG ASSEMBLY ONLY
NOTICE:

When disposing of the front passenger airbag assem-
bly only, never use the customer's vehicle to deploy
the airbag.

Be sure to follow the procedure given below when de-
ploying the airbag.
HINT:
Have a battery ready as the power source to deploy the airbag.
(a) Remove the front passenger airbag assembly
(See page RS-31).
CAUTION:

When removing the front passenger airbag assembly,
work must be started 90 seconds after the ignition
switch is turned to the ºLOCKº position and the nega-
tive (-) terminal cable is disconnected from the bat-
tery.

When storing the front passenger airbag assembly,
keep the upper surface of the airbag deployment side
facing upward.

SRS AIRBAG
PRECAUTION
CAUTION:

The LAND CRUISER is equipped with SRS, which comprises a driver airbag, front passenger
airbag, side airbag and curtain shield airbag. Failure to carry out service operations in the cor-
rect sequence could cause the SRS to unexpectedly deploy during servicing, possibly leading
to a 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 (including removal or
installation of parts, inspection or replacement), be sure to read the following items carefully,
then follow the correct procedures 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,
curtain shield airbag assembly, airbag sensor assembly, front airbag sensor, side and curtain
shield airbag sensor assembly, curtain shield airbag sensor assembly or seat position 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 the case of a minor collision where the SRS does not deploy, the steering wheel pad,
front passenger airbag assembly, side airbag assembly, curtain shield airbag assembly, airbag
sensor assembly, front airbag sensor, side and curtain shield airbag sensor assembly, curtain
shield airbag sensor assembly and seat position sensor assembly should be inspected (See
page RS-18, RS-32, RS-47, RS-60, RS-71, RS-76, RS-81, RS-87 and RS-92).

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, curtain shield airbag assembly, airbag sensor assembly, front airbag sensor,
side and curtain shield airbag sensor assembly, curtain shield airbag sensor assembly or seat
position sensor assembly in order to reuse it.

If the steering wheel pad, front passenger airbag assembly, side airbag assembly, curtain
shield airbag assembly, airbag sensor assembly, front airbag sensor, side and curtain shield
airbag sensor assembly, curtain shield airbag sensor assembly or seat position sensor assem-
bly has been dropped, or if there are cracks, dents or other defects in the case, bracket or con-
nector, 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 notice.

After work on the SRS is completed, perform the SRS warning light check (See page DI-692).

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. To avoid erasing the memory in each memory system, never
use a back- up power supply from outside the vehicle.

If the vehicle is equipped with a mobile communication system, refer to the precaution in the
IN section.

HINT:
Have a battery ready as the power source to deploy the airbag.
(a) Remove the steering wheel pad (See page SR-14).
CAUTION:

When storing the steering wheel pad, keep the upper
surface of the pad facing upward.

When removing the steering wheel pad, 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.
(b) Using a service-purpose wire harness for the vehicle, tie
down the steering wheel pad to the disc wheel.

or more (0.0019 in2. or more).
CAUTION:
If a wire harness which is too thin or some other thing is
used to tie down the steering wheel pad, 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

(0.0019 in2).
HINT:

(1) Install the 2 bolts with washers in the 2 bolt holes in
the steering wheel pad.
Bolt:
L: 35.0 mm (1.387 in.)
M: 6.0 mm (0.236 in.)
Pitch: 1.0 mm (0.039 in.)
NOTICE:

Tighten the bolts by hand until the bolts become diffi-
cult to turn.

Do not tighten the bolts excessively.
(2) Connect the connectors of the SST to the steering
wheel pad connectors.
