3. VEHICLE INVOLVED IN COLLISION AND AIRBAG IS
DEPLOYED
(a) Do diagnostic system check (See page DI−285).
(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 (with airbag), always first deploy the air-
bag in accordance 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 ”DISPOSAL”.
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). Perform the op-
eration in a place away from electrical noise.
SST 09082−00700
When deploying an airbag, perform the operation 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 deployed airbag.
Always wash your hands with water after completing
the operation.
Do not apply water, etc. to a steering wheel pad with
deployed airbag.

2. DEPLOYMENT WHEN DISPOSING OF STEERING
WHEEL PAD ONLY
NOTICE:
When disposing of the steering wheel pad (with air-
bag) only, never use the customers 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 steering wheel pad (See page SR−12).
CAUTION:
When storing the steering wheel pad, keep the upper sur-
face of the pad facing upward.
(b) Using a service−purpose wire harness for the vehicle 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
(1) .Install the 2 bolts with washer 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 too much.

(2) Using 3 wire harness, wind the wire harness at least
2 times each around the bolts installed on the left
and right sides of the steering wheel pad.
CAUTION:
Tightly wind the wire harness around the bolts so that
there is no slack.
If there is slackness in the wire harness, the steering
wheel pad may come loose due to the shock when the
airbag is deployed. This is highly dangerous.
(3) Face the upper surface of the steering wheel pad
upward. Separately tie the left and right sides of the
steering wheel pad to the disc wheel through the
hub nut holes. Position the steering wheel pad con-
nector so that it hangs downward through a hub
hole in the disc wheel.
CAUTION:
Make sure that the wire harness is tight. It is very dan-
gerous if looseness in the wire harness results in the
steering wheel pad coming free through the shock of
the airbag deploying.
Always tie down the steering wheel pad with the pad
side facing upward. It is very dangerous if the steer-
ing wheel pad is tied down with the metal surface fac-
ing to the airbag deploying direction and the steering
wheel pad will be thrown into the air.
HINT:
The disc wheel will be marked by airbag deployment, so when
disposing of the airbag use a redundant disc wheel.
(c) Check functioning of the SST.
