1995 TOYOTA SUPRA tires

There are some maintenance and inspection
items which are considered to be the owner's re-
sponsibility. They can be performed by the owner
or be can have them done at a service shop.
These items include those which should be
checked on a daily basis, those which, in most
cases, do not require (special) tools and those
which are considered to be reasonable for the
owner to perform. Items and procedures for gen-
eral maintenance are as follows:
OUTSIDE VEHICLE
1. TIRES
(a) Check the pressure with a gauge. Adjust if
necessary.
(b) Check for cuts, damage, uneven or excessive
wear.
2. WHEEL NUTS
When checking the tires, check the nuts for
looseness or for missing nuts. If necessary,
tighten them.
3. WINDSHIELD WIPER BLADES
Check for wear or cracks whenever they do not
wipe clean. Replace if necessary.
4. FLUID LEAKS
(a) Check underneath for leaking fuel, oil, water or
other fluid.
(b) If you smell gasoline fumes or notice any leak,
have the cause found and corrected.
5. DOORS AND ENGINE HOOD

12. REAR VIEW MIRROR
Check that it is mounted securely.
13. SUN VISORS
Check that they move freely and are
mounted securely.
14. STEERING WHEEL

alert for changes in steering condition, such
as excessive steering effort, excessive free-
play or strange noise.
15. SEATS
(a) Check that all front seat controls such as seat
adjusters, seatback recliner, etc. operate
smoothly.
(b) Check that all latches lock securely in any
position.
(c) Check that the locks hold securely in any

GENERAL MAINTENANCE
± MAINTENANCEGENERAL MAINTENANCEMA±17

PRECAUTION
wCare must be taken to replace parts properly because they could affect the
performance of the steering system and result in a driving hazard.
wThe steering wheel pad has an SRS (Supplemental Restraint System) airbag built in,
so take all due precautions when handling it. For more details, see the RS section.

STEERING WHEEL FREEPLAY CHECK
With the vehicle stopped and tires pointed straight ahead,
rock the steering wheel gently back and forth with light finger
pressure.
Freeplay should not exceed the maximum.

IDLE±UP CHECK
1. TURN AIR CONDITIONING SWITCH OFF
2. CHECK IDLE±UP
(a) Start engine and run it at idle.
(b) Fully turn the steering wheel.
(c) Check that the engine speed decreases when the air control
valve hose is pinched.
(d) Check that the engine speed increases when the hose is
released.
FLUID LEVEL CHECK
1. KEEP VEHICLE LEVEL
2. CHECK FLUID LEVEL
Check the fluid level in the reservoir.
If necessary, add fluid.
Fluid:
ATF DEXRON[ II
HINT: Check that the fluid level is within the HOT LEVEL
range on the dipstick of the reservoir cap. If the fluid is cold,
check that it is within the COLD LEVEL range.
3. BOOST FLUID TEMPERATURE
(a) Start the engine and run it at idle.
(b) Turn the steering wheel from lock to lock several times to
boost fluid temperature.
Fluid temperature:
805C (1765F)

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
± SUPPLEMENTAL RESTRAINT SYSTEMSTEERING WHEEL PAD AND SPIRAL CABLE

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
± SUPPLEMENTAL RESTRAINT SYSTEMFRONT PASSENGER AIRBAG ASSEMBLY

CAUTION: Make sure that the wire harnesses are tight. It
is very dangerous if loose wire harnesses result in the
tires coming free due to the shock of the airbag deploy-
ing.
HINT: Place the SST connector and wire harness inside tires.
Provide at least 1 m (3 ft) of slack for the wire harness.
5. INSTALL SST
Connect the SST connector to the front passenger airbag as-
sembly connector.
SST 09082±00700
NOTICE: To avoid damaging the SST connector and wire
harness, do not lock the secondary lock of the twin lock.
6. 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 tire the front
passenger airbag assembly 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.
7. DISPOSAL OF FRONT PASSENGER AIRBAG
ASSEMBLY
CAUTION:
wThe front passenger airbag assembly is very hot when
the airbag is deployed, so leave it alone for at least 30
minutes after deployment.
wUse gloves and safety glasses when handling a front
passenger airbag assembly with a deployed airbag.
wDo not apply water, etc. to a front passenger airbag
assembly with a deployed airbag.
wAlways wash your hands with water after completing the
operation.
(a) Remove the front passenger airbag assembly from the tire.
(b) Place the front passenger airbag assembly in a vinyl bag, tie
the end tightly and dispose of it the same way as other
general parts.
