Covering method using tires:
Place at least 3 tires with no disc wheels on top of
the tire with disc wheel to which the steering wheel
pad is tied.
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.
NOTICE:
The tires may be marked by the airbag deployment, so use
the redundant tires.
(f) Deploy the airbag.
(1) Connect the red clip of the SST to the battery posi-
tive (+) terminal and the black clip to the battery neg-
ative (-) terminal.
(2) Check that no one is within 10 m (33 ft) area around
the disc wheel which the steering wheel pad is tied
to.
(3) Press the SST activation switch and deploy the air-
bag.
HINT:
The airbag deploys as the LED of the SST activation switch
comes on.
(g) Dispose of the steering wheel pad (with airbag).
CAUTION:
The steering wheel pad is very hot when the airbag is
deployed, so leave it alone for at least 30 minutes af-
ter deployment.
Use gloves and safety glasses when handling a steer-
ing wheel pad with deployed airbag.
Always wash your hands with water after completing
the operation.
Do not apply water, etc. to a steering wheel pad with
deployed airbag.
(1) Remove the steering wheel pad from the disc
wheel.
(2) Place the steering wheel pad in a plastic bag, tie the
end tightly and dispose of it as the other general
parts disposal.

3. DEPLOYMENT WHEN DISPOSING OF STEERING
WHEEL PAD WITH AN AIRBAG DEPLOYED IN A COL-
LISION
Dispose of the steering wheel pad (with airbag).
CAUTION:
The steering wheel pad is very hot when the airbag is
deployed, so leave it alone for at least 30 minutes af-
ter deployment.
When moving a vehicle for scrapping which has a
steering wheel pad with the deployed airbag, use
gloves and safety glasses.
Use gloves and safety glasses when handling a steer-
ing wheel pad with the deployed airbag.
Always wash your hands with water after completing
the operation.
Do not apply water, etc. to a steering wheel pad with
the deployed airbag.
(1) Remove the steering wheel pad from the steering
wheel (See page SR-14).
(2) Place the steering wheel pad in a plastic bag, tie the
end tightly and dispose of it as the other general
parts disposal.

INSPECTION
1. Vehicle not involved in collision:
INSPECT SUPPLEMENTAL RESTRAINT SYSTEM
(a) Do a diagnostic system check (See page DI-692).
(b) Do a visual check which includes the following item with
the steering wheel pad (with airbag) installed in the ve-
hicle.
Check cuts, minute cracks or marked discoloration on the
steering wheel pad top surface and in the grooved por-
tion.
2. Vehicle involved in collision and airbag is not
deployed:
INSPECT SUPPLEMENTAL RESTRAINT SYSTEM
(a) Do a diagnostic system check (See page DI-692).
(b) Do a visual check which includes the following items with
the steering wheel pad (with airbag) removed from the ve-
hicle.
Check cuts, minute cracks or marked discoloration
on the steering wheel pad top surface and in the
grooved portion.
Check cuts and cracks in wire harness, and chip-
ping in connectors.
Check the deformation of the horn button contact
plate on the steering wheel pad (with airbag).
CAUTION:
For removal and installation of the steering wheel pad, see
page SR-14 and SR-24, and be sure to follow the correct
procedure.
HINT:
If the horn button contact plate of the steering wheel pad
(with airbag) is deformed, never repair it. Always replace
the steering wheel assembly with a new one.
There should be no interference between the steering
wheel pad and steering wheel, and the clearance should
be uniform all the way around when the new steering
wheel pad is installed on the steering wheel.

3. Vehicle involved in collision and airbag is deployed:
INSPECT SUPPLEMENTAL RESTRAINT SYSTEM
(a) Do a diagnostic system check (See page DI-692).
(b) Do a visual check which includes the following items with
the steering wheel pad (with airbag) removed from the ve-
hicle.
Check that the metal part where the steering wheel
pad is to be installed is not deformed.
Check the damage on the spiral cable connector
and wire harness.
HINT:
Do not repair the metal part where the steering wheel pad
is to be installed even if any deformation is found. Always
replace the steering wheel assembly with a new one.
There should be no interference between the steering
wheel pad and steering wheel, and the clearance should
be uniform all the way around when the new steering
wheel pad is installed on the steering wheel.

INSPECT SUPPLEMENTAL RESTRAINT SYSTEM
Do a diagnostic system check (See page DI-692).
2. Vehicle involved in collision:
INSPECT SUPPLEMENTAL RESTRAINT SYSTEM
(a) Do a diagnostic system check (See page DI-692).
(b) Check for breaks in all wires of the SRS wire harness, and for exposed conductors.
