(a)

Check the function of the SST (see step 1–(a)).

(b)

Remove the steering wheel pad (see page 

SR–14

).

CAUTION:

When removing the steering wheel pad, work must be
started 90 seconds after the ignition switch is turned
to the ”LOCK” position and the negative (–) terminal
cable is disconnected from the battery.

When storing the steering wheel pad, keep the airbag
deployment side facing upward.

(c)

Using a service–purpose wire harness for the vehicle, tie
down the steering wheel pad to the disc wheel.

. or more).

CAUTION:
If the wire harness is too thin or an alternative object is
used to tie down the steering wheel pad, it may be snapped
by the shock when the airbag is deployed. Always use a
wire harness for vehicle use with an area of at least 1.25
mm

(1)

Install the 2 bolts with washers into the 2 bolt holes
on the steering wheel pad.

Bolt:
L: 35.0 mm (1.378 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)

After connecting the SST below to each other, con-
nect them to the steering wheel pad connectors.

(3)

Using 3 wire harnesses, wind 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.

Make sure that the wire harness is tight. If there is
slack in wire harness, the steering wheel pad may be-
come loose due to the shock when the airbag is
deployed.

(4)

Face the airbag deployment side 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 SST con-
nector so that it hangs downward through the hub
hole in the disc wheel.

CAUTION:

Make sure that the wire harness is tight. If there is
slack in wire harness, the steering wheel pad may be-
come loose due to the shock when the airbag is
deployed.

Always tie down the steering wheel pad with the air-
bag deployment side facing upward.

NOTICE:
The disc wheel will be marked by the airbag deployment,
so use an extra disc wheel.

(d)

Install the SST.

CAUTION:
Place the disc wheel on level ground.

(1)

Connect the SST connector.

SST

09082–00700

CAUTION:
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 to the disc wheel.

(e)

Cover the steering wheel pad with a cardboard box or
tires.
Covering method using cardboard box:
Cover the steering wheel pad with the cardboard box and
place the weights on the cardboard box in 4 places total-
ling at least 190 N (19 kg, 43 lb).
Cardboard box size:
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 which the steering
wheel pad is tied to, 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 without disc wheels on the tire
with disc wheel which the steering wheel pad is tied
to. Place the tire with disc wheel on them.

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 except on the top and bot-
tom.
NOTICE:

The tires may be marked by the airbag deployment,
so use the redundant tires.

Do not place the SST connector under the tire be-
cause it could be damaged.

(1)

Tie the tires together with 2 wire harnesses.

CAUTION:
Make sure that the wire harness is tight. Looseness in the
wire harness results in the tires coming free due to the
shock when the airbag is deployed.

(f)

Deploy the airbag.
(1)

Connect the red clip of the SST to the battery posi-
tive (+) terminal and the black clip of the SST to the
battery negative (–) terminal.

(2)

Check that no one is within a 10 m (33 ft) radius of
the disc wheel which the steering wheel pad is tied
to.

(3)

Press the SST activation switch and deploy the air-
bag.

CAUTION:
When deploying the airbag, make sure that no one is near
the tire.
HINT:
The airbag is deployed as the LED of the SST activation switch
comes on.

(g)

Dispose of the steering wheel pad.

CAUTION:

The steering wheel pad becomes extremely hot when
the airbag is deployed, so do not touch it for at least
30 minutes after 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)

Remove the steering wheel pad from the disc
wheel.

(2)

Place the steering wheel pad in a plastic bag, tie it
tightly and dispose of it as other general part dispos-
al.
