INSPECTION
1. VEHICLE NOT INVOLVED IN COLLISION
(a) Do a diagnostic system check (See page DI-148).
(b) Do a visual check which includes the following items with
the steering wheel pad (with airbag) installed in the ve-
hicle.
Check for cuts, minute cracks or marked discoloration of
the steering wheel pad top surface and grooved portion.
2. VEHICLE INVOLVED IN COLLISION AND AIRBAG IS
NOT DEPLOYED
(a) Do a diagnostic system check (See page DI-148).
(b) Do a visual check which includes the following items with
the steering wheel pad (with airbag) installed in the ve-
hicle.

Check for cuts and cracks in, or marked discolor-
ation of the steering wheel pad top surface and
grooved portion.

Check for cuts and cracks in wire harnesses, and for
chipping in connectors.

Check for deformation of the horn button contact
plate of the steering wheel.
HINT:

If the horn button contact plate of the steering wheel is de-
formed, never repair it. Always replace the steering wheel
assembly with a new one.

There should be no interference between the steering
wheel pad and the steering wheel, and the clearance
should be uniform all the way around when the new steer-
ing wheel pad is installed on the steering wheel.

CAUTION:
For removal and installation of the steering wheel pad, see
page SR-13 and SR-20, and be sure to follow the correct
procedure.
3. VEHICLE INVOLVED IN COLLISION AND AIRBAG IS
DEPLOYED
(a) Do diagnostic system check (See page DI-148).
(b) Do a visual check which includes the following items with
the steering wheel pad (with airbag) removed from the ve-
hicle.

Check for deformation of the horn button contact
plate of the steering wheel.

Check for damage to the spiral cable connector and
wire harness.
HINT:

If the horn button contact plate of the steering wheel is de-
formed, never repair it. Always replace the steering wheel
assembly with a new one.

There should be no interference between the steering
wheel pad and the steering wheel, and the clearance
should be uniform all the way around when the new steer-
ing wheel pad is installed on the steering wheel.

DISPOSAL
HINT:
When scrapping vehicle equipped with an SRS or disposing of
a steering wheel pad, always first deploy the airbag in accor-
dance with the procedure described below. If any abnormality
occurs with the airbag deployment, contact the SERVICE
DEPT. of TOYOTA MOTOR SALES, U.S.A., INC.
When disposing of a steering wheel pad with an airbag
deployed in a collision, follow the same procedure given in step
1-(d) in ºDISPOSALº.
CAUTION:

Never dispose of a steering wheel pad which has an
undeployed airbag.

The airbag produces a sizeable exploding sound
when it deploys, so perform the operation out-of-
doors and where it will not create a nuisance to
nearby residents.

When deploying the airbag, always use the specified
SST (SRS Airbag Deployment Tool). Carry out opera-
tion in a place away from electrical noise.
SST 09082-00700

When deploying an airbag, do it at least 10 m (33 ft)
away from the steering wheel pad.

The steering wheel pad is very hot when the airbag is
deployed, so leave it alone for at least 30 minutes af-
ter deployment.

Use gloves and safety glasses when handling a steer-
ing wheel pad with a deployed airbag.

Do not apply water, etc. to a steering wheel pad with
a deployed airbag.

Always wash your hands with water after completing
the operation.

1. AIRBAG DEPLOYMENT WHEN SCRAPPING VE-
HICLE
HINT:
Have a battery ready as the power source to deploy the airbag.
(a) Check functioning of the SST.
CAUTION:
When deploying the airbag, always use the specified SST:
SRS Airbag Deployment Tool.
SST 09082-00700
(1) Connect the SST to battery.
Connect the red clip of the SST to the battery posi-
tive (+) terminal and the black clip to the battery neg-
ative (-) terminal.
HINT:
Do not connect the yellow connector which connects with the
SRS.
(2) Check functioning of the SST.
Press the SST activation switch, and confirm the
LED of the SST activation switch lights up.
CAUTION:
If the LED lights up when the activation switch is not being
pressed, SST malfunction is probable, so definitely do not
use the SST.
(b) Disconnect the airbag connector.
(1) Remove the No.1 under cover.
(2) Disconnect the airbag connector of the spiral cable.

(c) Install the SST.
(1) Connect the SST connector to the airbag connec-
tor.
SST 09082-00700
NOTICE:
To avoid damaging the SST connector and wire harness,
do not lock the secondary lock of the twin lock.
(2) Move the SST to at least 10 m (33 ft) away from the
front of the vehicle.
(3) Close all the doors and windows of the vehicle.
NOTICE:
Take care not to damage the SST wire harness.
(4) Connect the SST red clip to the battery positive (+)
terminal and the black clip to the negative (+) termi-
nal.
(d) Deploy the airbag.
(1) Confirm that no-one is inside the vehicle or within
10 m (33 ft) of the vehicle.
(2) 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.
(e) Dispose of the steering wheel pad.
CAUTION:

The steering wheel pad is very hot when the airbag is
deployed, so leave it alone for at least 30 minutes af-
ter deployment.

Use gloves and safety glasses when handling a steer-
ing wheel pad with a deployed airbag.

Do not apply water, etc. to a steering wheel pad with
a deployed airbag.

Always wash your hands with water after completing
the operation.
(f) When scrapping a vehicle, deploy the airbag and scrap
the vehicle with the steering wheel pad still installed.
2. DEPLOYMENT WHEN DISPOSING OF STEERING
WHEEL PAD ONLY
NOTICE:
When disposing of the steering wheel pad only, never use
the customers vehicle to deploy the airbag.
HINT:
Have a battery ready as the power source to deploy the airbag.
(a) Remove the steering wheel pad.

CAUTION:
When storing the steering wheel pad, keep the deployment
direction facing up.
(b) Fix the steering wheel pad.
(1) Using a service-purpose wire harness for the ve-
hicle tie down the steering wheel pad to the disc
wheel
Wire harness: Stripped wire harness section
1.25 mm
2 or more (0.0019 in.2 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
2 (0.0019 in.2).
HINT:
To calculate the square of the stripped wire harness section:
Square = 3.14 X (Diameter)
2 divided by 4
(2) Remove the connector on the steering wheel pad
rear surface from the inflater cover.
(3) Install the bolts and washers in the 3 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 too much.
