6. COVER STEERING WHEEL PAD WITH CARDBOARD
BOX OR TIRES
(Covering Method Using Cardboard Box)
Cover the steering wheel pad with the cardboard box and
weigh the cardboard box down in 4 places with at least 196
N (20 kg, 44 lb).
Size of cardboard box:
Must exceed the following dimensions±
x = 460 mm (18.11 in.)
When dimension ºyº of the cardboard box exceeds the
diameter of the disc wheel with tire the steering wheel
pad is tied to±
x = 460 mm (18.11 in.) + width of tire
y = 650 mm (25.59 in.)
NOTICE: If a cardboard box smaller than the size speci-
fied is used, the cardboard box will be broken by the
shock of the airbag deployment.
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 (7.28 in.)
Inner dia.: 360 mm (14.17 in.)
CAUTION: Do not use tires with disc wheels.
NOTICE: The tires may be marked by the airbag deploy-
ment, so use redundant tires.
7. AIRBAG DEPLOYMENT
(a) Connect the SST red clip to the battery positive (+) terminal
and the black clip to the battery negative (±) terminal.
(b) Confirm that no±one is within 10 m (33 ft) of the disc wheel
the steering wheel pad is tied to.
(c) Press the SST activation switch and deploy the airbag.
HINT: The airbag deploys simultaneously as the LED of the
SST activation switch lights up. RS±18

CAUTION: If the front passenger airbag assembly is tied
down by too thin a wire harness, it may snap. This is
highly dangerous. Always use a wire harness which is at
least 1.25 mm
2 (0.0019 in.2).
(1) Wrap the wire harness around the tire, passing the wire
harness through the installation holes which indicated in
the illustration by arrows.
(2) Position the front passenger airbag assembly inside the
tire with the airbag door facing inside.
Tire size: Must exceed the following dimensions±
Width: 185 mm (7.28 in.)
Inner dia.: 360 mm (14.17 in.)
CAUTION:
wMake sure the wire harness is tight. It is very dangerous
if a loose wire harness results in the front passenger
airbag assembly coming free due to the shock of the
airbag deploying.
wAlways tie down the front passenger airbag assembly
with the airbag door facing inside.
NOTICE: The tire will be marked by the airbag deploy-
ment, so use a redundant tire.
3. CONFIRM FUNCTIONING OF SST
(See page RS±19)
SST 09082±00700
4. PLACE TIRES
(a) Place at least 2 tires under the tire to which the front
passenger airbag assembly is tied.
(b) Place at least 2 tires over the tire to which the front passenger
airbag assembly is tied. The top tire should have the wheel
installed.
(c) Tie the tires together by 2 wire harnesses. RS±28

(b) Check the tire runout.
Tire runout:
Less than 1.4 mm (0.055 in.)
2. INSPECT WHEEL BALANCE
(a) Check and adjust the Off±the±car balance.
(b) If necessary, check and adjust the On±the±car balance.
Unbalance after adjustment:
5.0 g (0.011 lb) or less
3. CHECK WHEEL BEARING LOOSENESS
(a) Check the backlash in bearing shaft direction.
Maximum: 0.05 mm (0.0020 in.)
(b) Check the axle hub deviation.
Maximum: 0.05 mm (0.0020 in.)
4. CHECK FRONT SUSPENSION FOR LOOSENESS
5. CHECK STEERING LINKAGE FOR LOOSENESS
6. CHECK BALL JOINT FOR LOOSENESS
7. CHECK SHOCK ABSORBER WORK PROPERLY
wCheck for oil leak
wCheck mounting bushings for wear
wBounce front and rear of the vehicle

WHEEL ALIGNMENT
FRONT WHEEL ALIGNMENT
1. MEASURE VEHICLE HEIGHT
Front vehicle height
 Engine Tire size Height
 2JZ±GE 225/50ZR16 185 mm (7.28 in.)
 2JZ±GTE 235/45ZR17 187 mm (7.36 in.)
Measuring point:
Measure from the ground to the center of the lower suspen-
sion arm front mounting bolt.
NOTICE: Before inspecting the wheel alignment, adjust
the vehicle height to specification.
If the vehicle height is not to specification, try to adjust it by
pushing down on or lifting the body.
2. INSTALL CAMBER±CASTER±KINGPIN GAUGE OR

Follow the specific instructions of the equipment manufactur-
er.
