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
surface. An indicator light will illuminate to
indicate the defogger is operating.
Push the switch once again to turn the
defoggers off.
The system will automatically shut off af-
ter the defogger has operated about 15
minutes.
Make sure you turn the defogger off when
the window is clear. Leaving the defogger
on for a long time could cause the battery
to discharge, especially during stopand
go driving. The defogger is not designed
for drying rain water or for melting snow.
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 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.
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.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 stopandgo traffic.

(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) Low Engine 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.
(f) Malfunction Indicator Lamp
This lamp comes on when the ignition
key is turned to the “ON” position and
goes off after the engine starts. This
means that the warning light system is
operating properly.
If the lamp remains on, or the lamp
comes on while driving, first check the
followings.
Empty fuel tank
If the fuel tank is empty, refuel immedi-
ately.
Loose fuel tank cap
If the fuel tank cap is loose, securely
tighten it.
These cases are temporary malfunctions.
The malfunction indicator lamp will go off
after taking several driving trips.
If the lamp will not go off even after the
several trips, contact your Toyota dealer
as soon as possible.
If the fuel tank is not empty or the fuel
tank cap is not loose...
There is a problem somewhere in the
engine, emission control system, auto-
matic transmission electrical system or
warning light system itself.
Contact your Toyota dealer as soon as
possible to service the vehicle.
Emissions Inspection and Maintenance
(I/M) programs
Your vehicle may not pass a state
emission inspection if the malfunction
indicator lamp remains on. Contact your
Toyota dealer to check your vehicle’s
emission control system and OBD
(OnBoard Diagnostics) system before
taking your vehicle for the inspection.
For details, see “Emissions Inspection and
Maintenance (I/M) programs” on page 250
in Section 6.
