INSPECTION
1. VEHICLE NOT INVOLVED IN COLLISION
(a) Perform a diagnostic system check (see page DI±1147).
(b) With the steering wheel pad installed on the vehicle, per-
form a visual check. If there are any defects as mentioned
below, replace the steering wheel pad with a new one:
Cuts, minute cracks or marked discoloration on the steer-
ing wheel pad top surface or in the grooved portion.
2. VEHICLE INVOLVED IN A COLLISION AND AIRBAG IS
NOT DEPLOYED
(a) Perform a diagnostic system check (see page DI±1147).
(b) With the steering wheel pad removed from the vehicle,
perform a visual check. If there are any defects as men-
tioned below, replace the steering wheel pad or steering
wheel assembly with a new one:

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

Cracks or other damage to the connectors.

Deformation of the steering wheel assembly.

Deformation of the horn button contact plate of the horn
button assembly.

There should be no interference between the steering
wheel pad and steering wheel assembly, and the clear-
ance should be uniform all the way around when a new
steering wheel pad is installed on the steering wheel as-
sembly.

DISPOSAL
HINT:
When scrapping a vehicle equipped with SRS or disposing of
the steering wheel pad, be sure to deploy the airbag first in ac-
cordance with the procedure described below. If any abnormal-
ity occurs with the airbag deployment, contact the SERVICE
DEPT. of TOYOTA MOTOR SALES, USA, INC.
CAUTION:

Never dispose of a steering wheel pad which has an
undeployed airbag.

The airbag produces an exploding sound when it is
deployed, so perform the operation outdoors and
where it will not create a nuisance to nearby resi-
dents.

When deploying the airbag, always use the specified
SST (SRS Airbag Deployment Tool). Perform the op-
eration in a place away from electrical noise.

When deploying an airbag, perform the operation at
least 10 m (33 ft) away from the steering wheel pad.

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 the 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.
