To defog or defrost the rear window,
push the switch.
The key must be in the “ON” position.
The thin heater wires on the inside of the
rear window will quickly clear the window
surfaces. An indicator light will illuminate
to indicate the defogger is operating.
On some models, the rear view mirror
defoggers and/or the windshield wiper de−
icer is also operating simultaneously by
this switch. Vehicles with the outside rear
view mirror defoggers, the heater panel in
the outside rear view mirrors will quickly
clear the surfaces. Vehicles with the wind-
shield wiper de −icer, the windshield wiper
blades will be de −iced. Push the switch once again to turn the
defoggers off.
The system will automatically shut off af-
ter the defoggers have operated about 15
minutes.
CAUTION
On some models, since the mirror
surfaces can get hot, do not touch
them when the defogger switch is on.
Make sure you turn the defoggers off
when the surfaces are clear or the wiper
blades have de
−iced. Leaving the defog-
gers 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 or
damage the heater wires or connec-
tors.

Low fuel level
warning light
The gauge indicates the approximate
quantity of 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.
The needle moves when braking, acceler-
ating or making turns. This is caused by
the movement of the fuel in the tank.
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.
It is not a malfunction even if the needle
of the fuel gauge returns to “E” when the
ignition switch is turned to the “START”
position.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.
It is not a malfunction even if the needle
of the engine coolant temperature gauge
returns to “C” when the ignition switch is
turned to the “START” position.
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” on page 420 in
Section 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 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.
It is not a malfunction even if the needle
of the tachometer returns to the bottom
position when the ignition switch is turned
to the “START” position.
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—It 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.
