To squirt washer fluid, pull the lever
toward you and release it.
If the windshield wipers are off, they will
operate a couple of times after the washer
squirts.
For instructions on adding washer fluid,
see “Adding washer fluid” in Section 7 −3.
In freezing weather, warm the windshield
with the defroster before using the washer.
This will help prevent the washer fluid
from freezing on your windshield, which
can block your vision.
NOTICE
Do not operate the wipers if the wind-
shield is dry. It may scratch the
glass.

To defog or defrost the outside rear
view mirrors, push the switch.
The key must be in the “ON” position.
The heater panels in the outside rear view
mirrors will quickly clear the mirror sur-
faces. An indicator light will illuminate to
indicate the mirror heaters are operating.
Push the switch once again to turn the
mirror heaters off.
The system will automatically shut off af-
ter the mirror heaters have operated about
15 minutes.
CAUTION
Since the mirror surfaces can get hot,
do not touch them when the switch
is on.
Make sure you turn the mirror heaters off
when the mirror surfaces are clear. Leav-
ing the mirror heaters on for a long time
could cause the battery to discharge, es-
pecially during stop−and− go driving. The
mirror heaters 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.

The gauge indicates the approximate
quantity of the fuel remaining in the
tank when the ignition switch is on.
Nearly full—Needle at “F”
Nearly empty—Needle at “E”
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 “E” 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.

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 moves into the red zone,
your engine is too hot. If your vehicle
overheats, 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.
Towing a trailer.
NOTICE
Do not remove the thermostat in
the engine cooling system as this
may cause the engine to overheat.
The thermostat is designed to con-
trol the flow of coolant to keep the
temperature of the engine within
the specified operating range.
 Do not continue driving with an
overheated engine. See “If your ve-
hicle overheats” in Section 4.
IdlingNormal
driving
The oil pressure gauge indicates engine
oil pressure when the ignition switch is
on. Check it while driving to make sure
that the needle is in the proper range.
If the oil pressure should stay below the
normal range, pull off the road to a safe
place and stop the engine immediately.
Call a Toyota dealer or qualified repair
shop for assistance.
Oil pressure may not build up when the
oil level is too low. The oil pressure
gauge is not designed to indicate oil level,
and the oil level must be checked using
the level dipstick.

NOTICE
Do not drive the vehicle with the oil
pressure below the normal range until
the cause is fixed—it may ruin the
engine.
The voltmeter tells whether the battery
is charged or discharged. Check it
while the engine is running—the needle
should always indicate as shown above.
If the needle reads below or above the
normal range while the engine is running,
it indicates the charging system needs im-
mediate repair.
However, it is normal for the needle to
drop below the normal range during en-
gine starting.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 cause
severe engine damage.

This meter displays the odometer and
two trip meters.
1. Odometer—Shows the total distance the vehicle has been driven.
2. Two trip meters—Show two different distances independently driven since
the last time each trip meter was set
to zero.
You can use one trip meter to calculate
the fuel economy and the other to
measure the distance on each trip. All
trip meter data is cancelled if the elec-
trical power source is disconnected. 3. Trip meter reset knob—Resets the two
trip meters to zero, and also change
the meter display.
To change the meter display, quickly
push and release the knob. The meter
display changes in the order from the
odometer to trip meter A to trip meter
B, then back to the odometer each
time you push.
To reset the trip meter A to zero, dis-
play the meter A reading, then push
and hold the knob until the meter is
set to zero. The same process can be
applied for resetting the trip meter B.
