HINT:

To calculate the area of the stripped wire harness section:

CAUTION:



When removing the steering pad, work must be started 90
seconds after the ignition switch is turned OFF and the
negative (-) terminal cable is disconnected from the
battery.



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

CAUTION: If the wire harness is too thin or an alternative object is used to

tie down the steering 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 pad.

Bolt:

L: 35.0 mm (1.38 in.)

M:

6.0 mm (0.236 in.)

Pitch:

1.0 mm (0.0394 in.)

2. After connecting SST each other, connect them to the steering pad.

NOTE:



Tighten the bolts by hand until they become difficult to
turn.



Do not tighten the bolts excessively.

3. Wind 3 wire harnesses at least 2 times each around the bolts installed on the left and right

sides of the steering pad.

4. Face the airbag deployment side of the steering pad upward. Separately tie the left and right

sides of the steering pad to the disc wheel through the hub nut holes. Position SST connector
so that it hangs downward through the hub hole of the disc wheel.

CAUTION:



Tightly wind the wire harnesses around the bolts so
that there is no slack.



Make sure that the wire harnesses are tight. If there is
slack in the wire harnesses, the steering pad may
become loose due to the shock when the airbag is
deployed.

2. Move SST at least 10 m (32.8 ft.) away from the steering pad tied down to the disc wheel.

NOTE:

As the disc wheel may be damaged by the airbag deployment,
use a disc wheel that you are planning to throw away.

CAUTION: Place the disc wheel on level ground.

NOTE:

To avoid damaging SST connector and wire harness, do not
lock the secondary lock of the twin lock. Also, secure some
slack for SST wire harness inside the disc wheel.
