If the washer does not work, check to see
whether the washer tank is empty. For in-
formation on adding washer fluid, see
Adding 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 windshield is dry. It may scratch the
glass.
To turn the rear wiper and washer on,
twist the knob at the end of the lever. The key must be in the ONº position.
The wiper will operate at intervals when the knob is in the INTº position.
The washer squirts at the two marked
knob positions. The knob will automatical-
ly 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 in-
formation on adding washer fluid, see
Adding washer fluidº in Chapter 7-3.
NOTICE
Do not operate the rear wiper if the rear window is dry. It may scratch
the glass.
To defog or defrost the rear window,
push the switch. The key must be in the ONº 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 you hands off the
mirror faces when the switch is on. Push the switch once again to turn the de-
foggers off.
The system will automatically shut off af-
ter the defoggers have operated about 15minutes.

48Make 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 heavily coated with ice, use a spray de-icer be-
fore operating the switch.
NOTICE
When cleaning the inside of the rear window, be careful not to
scratch or damage the heater wires.

OPERATION OF INSTRUMENTS AND CONTROLSÐ
Chapter 1-5 Gauges, Meters and Service reminderindicators
Fuel gauge
Engine coolant temperature gauge
Tachometer
Odometer and two trip meters
Service reminder indicators and warning buzzers
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 wh ich remains at the last indicated
position when the ignition switch is turned
off.
If the fuel level approaches Eº or the low fuel level warning light comes on, fill the fuel tank as soon as possible.
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 assoon as possible.

50
The gauge indicates the engine cool-
ant temperature when the ignition
switch is on. The engine operating
temperature will vary with changes inweather and engine load.
If the needle points to the red zone or high-
er, 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 con-
ditioning on in stop-and-go traffic.
NOTICE
Do not remove the thermostat in the engine cooling system as this
may cause the engine to overheat. The thermostat is designed tocontrol the flow of coolant to keep
the temperature of the engine within the specified operatingrange.
Do not continue driving with an
overheated engine. See If yourvehicle overheatsº in Part 4.
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 overr evving.
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 cause
severe engine damage.

This meter displays the odometer and
two trip meters. To change the odome-
ter display to the trip meter display,
push the ODO TRIPº button. To reset
the trip meter A to zero, display the me-
ter A reading, then push the RESETº
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 measure the distance on each trip. All trip meterdata is cancelled if the electrical power source is disconnected.The meter display changes each time youpush the ODO TRIPº button, changing in order from the odometer to trip meter A to
trip meter B, then back to the odometer.
