(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 though 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 of the airbag deploying and the steering wheel
pad will be thrown into the air.

NOTICE:
The disc wheel will be marked by airbag deployment, so
use the spare disc wheel.
(d)

Confirm functioning of the SST.

cure some slack for the SST wire harness inside the disc
wheel.

(2)

Move the SST to at least 10 m (33 ft) away from the
steering wheel pad tied down on the disc wheel.

box and weight the cardboard box down in 4 places
with at least 196 N (20 kg, 44 lb).

Size of cardboard box:
Must exceed the following dimensions:
x=460 mm (18.11 in.)
When dimension of the cardboard box exceeds the di-
ameter of the disc wheel with tire to which the steer-
ing wheel pad is tied –
x=460 mm (18.11 in.) + width of tire
y= 650 mm (25.59 in.)

NOTICE:
If a cardboard box smaller than the specified size is used,
the cardboard box will be broken by the shock from the air-
bag deployment.

Covering method using tires:
Place at least 3 tires without disc wheel on top of the
disc wheel with tire to which the steering wheel pad
is tied.

Tire size: Must exceed the following dimensions–
Width: 185 mm (7.87 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 disc wheel which the steering wheel pad is tied
to.
