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 redundant tires.
(g) Deploy the airbag.
(1) Connect the SST red clip to the battery positive (+)
terminal and the black clip to the battery negative
(-) 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 simultaneously as the LED of the SST ac-
tivation switch lights up.
(h) 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 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 disc
wheel.
(2) Place the steering wheel pad in a vinyl bag, tie the
end tightly and dispose of it in the same way as oth-
er general parts disposal.

STEERING WHEEL
INSPECTION
1. CHECK STEERING WHEEL FREEPLAY
(a) Stop the vehicle and face the tires straight ahead.
(b) Rock the steering wheel gently up and down with a finger
lightly, check the steering wheel freeplay.
Maximum freeplay: 30 mm (1.18 in.)
2. CHECK STEERING EFFORT
(a) Center the steering wheel.
(b) Remove the steering wheel pad (See page SR-12).
(c) Start the engine and run it at idle.
(d) Measure the steering effort in both directions.
Steering effort (Reference)
5.9 N´m (60 kgf´cm, 52 in.´lbf)
HINT:
Take the tire type, pressure and contact surface into consider-
ation before making your diagnosis.
(e) Torque the steering wheel set nut.
Torque: 50 N´m (510 kgf´cm, 37 ft´lbf)
(f) Install the steering wheel pad (See page SR-22).

TIRE AND WHEEL
INSPECTION
1. INSPECT TIRE
(a) Check the tires for wear and proper inflation pressure.
Cold tire inflation pressure:
Tire sizeFront, rear
kPa (kgf/cm2, psi)
P205/65R15 92H210 (2.1, 31)
P205/60R16 91H220 (2.2, 32)
(b) Check the tire runout.
Tire runout: 1.0 mm (0.039 in.) or less
2. ROTATING TIRES
HINT:
See the illustration for where to rotate each tire when you in-
clude the spare tire in the rotation and when you do not.
3. INSPECT WHEEL BALANCE
(a) Check and adjust the Off-the-car balance.
(b) If necessary, check and adjust the On-the-car balance.
Imbalance after adjustment: 8.0 g (0.018 lb) or less
