1995 TOYOTA SUPRA tire pressure

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
(a) Check that all doors including the trunk lid
operate smoothly, and that all latches lock
securely.
(b) Check that the engine hood secondary latch
secures the hood from opening when the
primary latch is released.
INSIDE VEHICLE
6. LIGHTS
(a) C h e c k t h a t t h e headlights, stop lights,
tail±lights, turn signal lights, and other lights
are all working.
(b) Check the headlight aiming.7. WARNING LIGHT AND BUZZERS
Check that all warning lights and buzzers
function properly.
8. HORN
Check that it is working.
9. WINDSHIELD GLASS
Check for scratches, pits or abrasions.
10. WINDSHIELD WIPER AND WASHER
(a) Check operation of the wipers and washer.
(b) Check that the wipers do not streak.
11. WINDSHIELD DEFROSTER
Check that the air comes out from the defrost-
er outlet when operating the heater air condi-
tioner at defroster mode.
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
Check that it has the specified freeplay. Be
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
latched position.
(d) Check that the head restraints move up and
down smoothly and that the locks hold
securely in any latched position.
(e) For folding±down rear seat backs, check that
the latches lock securely.
16. SEAT BELTS
(a) Check that the seat belt system such as
buckles, retractors and anchors operate
properly and smoothly.
(b) Check that the belt webbing is not cut, frayed,
worn or damaged.
17. ACCELERATOR PEDAL
Check the pedal for smooth operation and
uneven pedal effort or catching.

ON±VEHICLE INSPECTION
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.
 

 
 Freeplay mm(in.) 
Maximum30 (1 18) Maximum30 (1.18)
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)
± STEERINGON±VEHICLE INSPECTIONSR±7

5. CHECK FLUID PRESSURE READING WITH VALVE
OPENED
(a) With the engine idling, open the valve fully.
(b) Measure the fluid pressure at engine speeds of 1,000 rpm
and 3,000 rpm.
 
 
 
 Fluid pressure kPa (kgf/cm2, psi)
 Difference 490 (5, 71) or less
NOTICE: Do not turn the steering wheel.
6. CHECK FLUID PRESSURE READING WITH STEERING
WHEEL TURNED TO FULL LOCK
With the engine idling and valve fully opened, turn the wheel
to full lock.
   Fluid pressure kPa (kgf/cm2, psi) 
 Minimum
 
 7,355 (75, 1,067)
NOTICE:
wDo not maintain lock position for more than 10
seconds.
wDo not let the fluid temperature become too high.
7. DISCONNECT OIL PRESSURE GAUGE
(a) Disconnect the pressure gauge.
(b) Connect the pressure feed tube.
(See page SR±32)
8. BLEED POWER STEERING SYSTEM
(See page SR±9)
STEERING EFFORT MEASUREMENT
1. CENTER STEERING WHEEL
2. MEASURE STEERING EFFORT
(a) Remove the steering wheel pad.
(See page SR±14)
(b) Start the engine and run it at idle.
(c) Measure the steering effort in both directions.
Maximum steering effort:
6.9 NVm (70 kgfVcm, 61 in.Vlbf)
If steering effort is excessive, repair the power steering unit.
HINT: Be sure to consider the tire type, pressure and contact
surface before making your diagnosis.
(d) Tighten the steering wheel set nut.
Torque: 35 NVm (360 kgfVcm, 26 ftVlbf)
(e) Install the steering wheel pad.
