Windshield wipers and washer
To turn the wipers on, move the lever.
To make the washer squirt, pull the le-
ver toward you.
The key must be in the ºONº position.
The wipers will operate at intervals when
the lever is in the ºINTº position. With the
lever in this position, the wipers can be
adjusted to operate at intervals of 3 to 12
seconds depending on the interval adjuster
setting between ºSº and ºFº.
Also, the wipers will automatically operate
a couple of times after the washer squirts
even with the lever in the ºOFFº position.
If the washer does not work, check to see
whether the washer tank is empty. For
information on adding washer fluid, see
ºAdding washer fluidº in Chapter 7- 3.
In cold weather, warm the windshield with
the defroster before using the washer.
This will help prevent icing, which could
block your vision.
NOTICE
Do not operate the wipers if the wind-
shield is dry. It may scratch theglass.
Rear window wiper and washer
To turn the rear wiper and washer on,
twist the knob at the end of the lever.
The key must be in the ºONº position.
The wiper will operate at intervals when
the knob is in the ºINTº position.
The washer squirts at the two marked
knob positions. The knob will automatically
return from these positions when it is re-
leased.
If the washer does not work, check to see
whether the washer tank is empty. For
information on adding washer fluid, see
ºAdding washer fluidº in Chapter 7- 3.

NOTICE
Do not operate the rear wiper if the rear window is dry. It may scratch theglass.
To defog or defrost the rear window,
push the switch.
The key must be in the ºONº position.
The thin heater wires on the inside of the
rear window will quickly clear the window
surface. An indicator light will illuminate to
indicate the defogger is operating.
On some models, the heater panels in the
outside rear view mirrors will also quickly
clear the surfaces. Keep your hands off
the mirror faces when the switch is on.
Push the switch once again to turn the
defoggers off.
CAUTION
Since the mirror surfaces can get hot,
keep your hands off them when the
defogger switch is on.
The system will automatically shut off af-
ter the defoggers have operated about 15
minutes.
Make sure you turn the defoggers off
when the surfaces are clear. Leaving the
defoggers on for a long time could cause
the battery to discharge, especially during
stop- and- go driving. The defoggers are
not designed for drying rain water or for
melting snow.
If the outside rear view mirrors are heavi-
ly coated with ice, use a spray de- icer
before operating the switch.
NOTICE
When cleaning the inside of the rear
window, be careful not to scratch ordamage the heater wires.

OPERATION OF
INSTRUMENTS
AND CONTROLSÐ
Chapter 1- 5
Gauges, Meters
and Service reminder indicators
Fuel gauge
Engine coolant temperature gauge
Tachometer
Odometer and two trip meters
Service reminder indicators and
warning buzzers
Fuel gauge
The gauge works when the ignition
switch is on and indicates the approxi-
mate quantity of fuel remaining in the
tank.
It is a good idea to keep the tank over
1/4 full.
This fuel gauge has a non- return type
needle which remains at the last indicated
position when the ignition switch is turned
off.
If the fuel level approaches ºEº or the low
fuel level warning light comes on, fill the
fuel tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the fuel gauge
needle may fluctuate or the low fuel level
warning light may come on earlier than
usual.
If the fuel tank is completely empty, the
malfunction indicator lamp comes on. Fill
the fuel tank immediately.
The indicator lamp goes off after driving
several times. If the indicator lamp does
not go off, contact your Toyota dealer as
soon as possible.

SUPRA (U)
60
The gauge indicates the engine coolant
temperature when the ignition switch is
on. The engine operating temperature
will vary with changes in weather and
engine load.
If the needle points to the red zone or
higher, stop your vehicle and allow the
engine to cool.
Your vehicle may overheat during severe
operating conditions, such as: Driving up a long hill on a hot day.
Reducing speed or stopping after high
speed driving.
Idling for a long period with the air
conditioning on in stop- and- go traffic.
NOTICE
Do not remove the thermostat in
the engine cooling system as thismay cause the engine to overheat.The thermostat is designed to con-
trol the flow of coolant to keep thetemperature of the engine withinthe specified operating range.
Do not continue driving with anoverheated engine. See ºIf yourvehicle overheatsº in Part 4.
Tachometer
The tachometer indicates engine speed
in thousands of rpm (revolutions per
minute). Use it while driving to select
correct shift points and to prevent en-
gine lugging and overrevving.
Driving with the engine running too fast
causes excessive engine wear and poor
fuel economy. Remember, in most cases
the slower the engine speed, the greater
the fuel economy.
NOTICE
Do not let the indicator needle get
into the red zone. This may causesevere engine damage.

Odometer and two trip meters
This meter displays the odometer and
two trip meters. To change the odome-
ter display to the trip meter display,
push the ºODO TRIPº button. To reset
the trip meter A to zero, display the
meter A reading, then push the
ºRESETº button. The same applies for
the trip meter B.
The odometer records the total distance
the vehicle has been driven. The trip me-
ters can record two different distances in-
dependently.
You can use one trip meter to calculate
the fuel economy and the other to mea-
sure the distance on each trip. All trip
meter data is cancelled if the electrical
power source is disconnected.
The meter display changes each time you
push the ºODO TRIPº button, changing in
order from the odometer to trip meter A
to trip meter B, then back to the odome-
ter.

(a) Master Warning Light
This light warns that another service re-
minder indicator (except seat belt reminder
light, low fuel level warning light, rear light
failure warning light, SRS airbag warning
light and ºTRAC OFFº indicator/warning
light) is on.
If it comes on while you are driving,
check the other service reminder indicator
that is on with reference to the following
description of the indicator.
(b) Brake System Warning Light
This light has the following functions:
Parking brake reminder
If this light is on, make sure the parking
brake is fully released. The light should
go off.
Low brake fluid level warning
If this light comes on and stays on while
you are driving, slow down and pull off
the road. Then stop the vehicle carefully.
Remember that stopping distance and ped-
al effort may be increased. There may be
a problem somewhere in the brake sys-
tem. Check the fluid level of the see-
through reservoir.

SUPRA (U)63
To make sure the parking brake has not
caused the warning light to come on,
check to see that the parking brake is
fully released.
If the brake fluid level is low...
At a safe place, test your brakes by start-
ing and stopping.
If you judge that the brakes still work
adequately, drive cautiously to your
nearest dealer or shop for repairs.
If the brakes are not working, have the
vehicle towed in for repairs. (For tow-
ing information, see Part 4.)
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
If the brake fluid level is correct...
Have the warning system checked by your
Toyota dealer. (c) Seat Belt Reminder Light and Buzz-er
Once the ignition key is turned to ºONº or
ºSTARTº, the reminder light flashes and
buzzer comes on if the driver's seat belt
is not fastened. Unless the driver fastens
the belt, the light keeps flashing and the
buzzer stops after about 4 to 8 seconds.
(d) Discharge Warning Light
This light warns that the battery is being
discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging
system.
The engine ignition will continue to oper-
ate, however, until the battery is dis-
charged. Turn off the air conditioning,
blower, radio, etc., and drive directly to
the nearest Toyota dealer or repair shop.NOTICE
Do not continue driving if the engine
drive belt is broken or loose.
(e) Malfunction Indicator Lamp
This lamp comes on in the following
cases.
a. The fuel tank is completely empty. (See
ºFuel gaugeº in Chapter 1- 5 for instruc-
tions.)
b. The fuel tank cap is not tightened se-
curely. (See ºFuel tank capº in Chapter
1- 2 for instructions.)
c. There is a problem somewhere in your
engine or automatic transmission electrical
system.
If it comes on while you are driving in
case c, have your vehicle checked/re-
paired by your Toyota dealer as soon as
possible.
(f) Low Fuel Level Warning Light
This light comes on when the fuel level
in the tank becomes nearly empty. Fill up
the tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the low fuel level
warning light may come on earlier than
usual.

SUPRA (U)

(g) Low Oil Pressure Warning Light
This light warns that the engine oil pres-
sure is too low.
If it flickers or stays on while you are
driving, pull off the road to a safe place
and stop the engine immediately. Call a
Toyota dealer or qualified repair shop for
assistance.
The light may occasionally flicker when
the engine is idling or it may come on
briefly after a hard stop. There is no
cause for concern if it then goes out when
the engine is accelerated slightly.
The light may come on when the oil level
is extremely low. It is not designed to
indicate low oil level, and the oil level
must be checked using the level dipstick.
NOTICE
Do not drive the vehicle with the
warning light on±even for one block.It may ruin the engine.
(h) Low Engine Oil Level Warning Light
The light warns that the engine oil level is
too low. Add oil as soon as possible. (For
instructions, see ºChecking the engine oil
levelº in Chapter 7- 2.) While driving on steep inclines or rough
roads which causes the vehicle to sub-
stantially sway or on curves, this light
may come on due to the movement of
engine oil in the engine.
NOTICE
Continued engine operation with low
engine oil will damage the engine.
(i) ºABSº Warning Light
This light warns that there is a problem
somewhere in your anti- lock brake sys-
tem.
If the light comes on while you are driv-
ing, have your vehicle checked by your
Toyota dealer as soon as possible.
The light will come on when the ignition
key is turned to the ºONº position. After
a few seconds, the light will go off.
When the ºABSº warning light is on (and
the brake system warning light is off), the
brake system operates conventionally but
anti- lock brake system is not assisting
brake performance so that the wheels can
lock- up during sudden braking or braking
on slippery road surfaces. (j) Open Door Warning Light
This light remains on until both side doors
and back door are completely closed.
(k) Rear Light Failure Warning Light
If this light comes on when the headlight
switch is turned on (at the first or second
clickstop), it indicates that one or more of
the tail lights are burned out.
If it comes on when the brake pedal is
depressed, one or more stop lights are
burned out or the stop light circuit is in
need of repair.
Have defective bulbs replaced as soon as
possible.
(l) SRS Airbag Warning Light
This light will come on when the igni-
tion key is turned to the ºACCº or
ºONº position. After about 6 seconds,
the light will go off. This means the
airbag system is operating properly.
The warning light system monitors the air-
bag sensor assembly, inflators, warning
light, interconnecting wiring and power
sources.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle.
