(7) Connect the connector of SST to the airbag con-
nector of the spiral cable.
SST 09082-00700, 09082-00780
NOTICE:
To avoid damaging the connector of the SST and wire har-
ness, do not lock the secondary lock of the twin lock.
(8) Move the SST at least 10 m (33 ft) away from the
front of the vehicle.
(9) Close all the doors and windows of the vehicle.
NOTICE:
Take care not to damage the SST wire harness.
(10) Connect the SST red clip to the battery positive (+)
terminal and the black clip to the negative (-) termi-
nal.
(c) Deploy the airbag.
(1) Confirm that no one is inside the vehicle nor within
10 m (33 ft) area around the vehicle.
(2) Press the SST activation switch and deploy the air-
bag.
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.

When moving a vehicle for scrapping which has a
steering wheel pad with deployed airbag, use gloves
and safety glasses.

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

Always wash your hands with water after completing
the operation.

Do not apply water, etc. to a steering wheel pad with
the deployed airbag.
HINT:
The airbag deploys as the LED of the SST activation switch
comes on.
2. DEPLOYMENT WHEN DISPOSING OF STEERING
WHEEL PAD ONLY
NOTICE:

When disposing of the steering wheel pad (with air-
bag) 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 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.
Wire harness: Stripped wire harness section
1.25 mm
2
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
2
(0.0019 in2).
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 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.

(3) 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.
(4) 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 when looseness in the wire harness results in
the steering wheel pad coming free through the shock
from 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 upward as the wire harness will be cut by the
shock caused by the airbag is deployment and the
steering wheel pad will be thrown into the air.
NOTICE:
The disc wheel will be marked by airbag deployment, so
when disposing of the airbag, use a redundant disc wheel.
(c) Check the function of the SST (See step 1-(a)).

(d) Install the SST.
CAUTION:
Place the disc wheel on the level ground.
(1) Connect the connector of the SST.
SST 09082-00700
NOTICE:
To avoid damaging the SST connector and wire harness,
do not lock the secondary lock of the twin lock. Also, se-
cure some slack for the SST wire harness inside the disc
wheel.
(2) Move the SST at least 10 m (33 ft) away from the
steering wheel pad tied down on the disc wheel.
(e) Cover the steering wheel pad with a cardboard box or
tires.

Covering method using a cardboard box:
Cover the steering wheel pad with the cardboard
box and weight the cardboard box down in 4 places
with at least 190 N (20 kg, 44 lb).
Size of cardboard box:
Must exceed the following dimensions:
X = 460 mm (18.11 in.)
Y = 650 mm (25.59 in.)
NOTICE:

When dimension Y of the cardboard box exceeds the
diameter of the disc wheel with tire to which the steer-
ing wheel pad is tied, X should be the following size.
X = 460 mm (18.11 in.) + width of tire

If a cardboard box smaller than the specified size is
used, the cardboard box will be broken by the shock
from the airbag deployment.

Covering method using tires:
Place at least 3 tires with no disc wheels on top of
the tire with disc wheel to which the steering wheel
pad is tied.
Tire size: Must exceed the following dimensions-
Width: 185 mm (7.28 in.)
Inner diameter: 360 mm (14.17 in.)
CAUTION:
Do not use tires with disc wheels.
NOTICE:
The tires may be marked by the airbag deployment, so use
the redundant tires.
(f) Deploy the airbag.
(1) Connect the red clip of the SST to the battery posi-
tive (+) terminal and the black clip to the battery neg-
ative (-) terminal.
(2) Check that no one is within 10 m (33 ft) area around
the disc wheel which the steering wheel pad is tied
to.
(3) Press the SST activation switch and deploy the air-
bag.
HINT:
The airbag deploys as the LED of the SST activation switch
comes on.
(g) Dispose of the steering wheel pad (with airbag).
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 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.
(1) Remove the steering wheel pad from the disc
wheel.
(2) Place the steering wheel pad in a plastic bag, tie the
end tightly and dispose of it as the other general
parts disposal.

INSPECTION
1. Vehicle not involved in collision:
INSPECT SUPPLEMENTAL RESTRAINT SYSTEM
(a) Do a diagnostic system check (See page DI-692).
(b) Do a visual check which includes the following item with
the steering wheel pad (with airbag) installed in the ve-
hicle.
Check cuts, minute cracks or marked discoloration on the
steering wheel pad top surface and in the grooved por-
tion.
2. Vehicle involved in collision and airbag is not
deployed:
INSPECT SUPPLEMENTAL RESTRAINT SYSTEM
(a) Do a diagnostic system check (See page DI-692).
(b) Do a visual check which includes the following items with
the steering wheel pad (with airbag) removed from the ve-
hicle.

Check cuts, minute cracks or marked discoloration
on the steering wheel pad top surface and in the
grooved portion.

Check cuts and cracks in wire harness, and chip-
ping in connectors.

Check the deformation of the horn button contact
plate on the steering wheel pad (with airbag).
CAUTION:
For removal and installation of the steering wheel pad, see
page SR-14 and SR-24, and be sure to follow the correct
procedure.
HINT:

If the horn button contact plate of the steering wheel pad
(with airbag) is deformed, never repair it. Always replace
the steering wheel assembly with a new one.

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