and the negative (–) terminal cable is disconnected
from the battery.

Store the front passenger airbag assembly with the
airbag deployment direction facing upward.

(b)

Fix the front passenger airbag assembly to tire.

(5)

Position the front passenger airbag assembly in-
side the tire with the airbag deployment direction
facing inside.

Tire size: Must exceed the following dimensions–
Width: 185 mm (7.28 in.)
Inner diameter: 360 mm (14.17 in.)

CAUTION:

Make sure that the wire harness is tight. It is very dan-
gerous if looseness in the wire harness results in the
front passenger airbag assembly coming free due to
the shock of the airbag deploying.

Always tie down the front passenger airbag assembly
with the airbag door facing inside.

NOTICE:
The tire will be marked by the airbag deployment, so use a
redundant tire.

(c)

Confirm functioning of the SST.

passenger airbag assembly is tied. The top tire
should have the wheel installed.

CAUTION:
Make sure that the wire harnesses are tight. It is very dan-
gerous if loose wire harnesses result in the tires coming
free due to the shock of the airbag deploying.
HINT:
Place the SST connector and wire harness inside tires. Provide
at least 1 m (3 ft) of slack for the wire harness.
