LIGHTS, WIPERS AND DEFOGGER121
Rear window defogger
MS14010a
To defog or defrost the rear window,
push the switch.
The engine switch 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
defogger off.
Make sure you turn the defogger off when
the window surface is clear. Leaving the
defogger on for a long time could cause
the battery to discharge, especially during
stop−and−go driving. The defogger is not
designed for drying rain water or for melt-
ing snow.
NOTICE
zTo prevent the battery from being
discharged, turn the switch off
when the engine is not running.
zWhen cleaning the inside of the
rear window, be careful not to
scratch or damage the heater wires
or connectors.

Fuel gauge
MS15001
The gauge indicates the approximate
quantity of fuel remaining in the tank
when the engine switch is on.
Nearly full—Indicator at “1/1”
Nearly empty—Indicator at “R”
It is a good idea to keep the tank over
1/3 full.
MS15002
If the low fuel level warning light blinks
and the warning buzzer comes on, fill the
fuel tank as soon as possible. Further fuel
reduction makes the light blink quicker.
On incline or curves, due to the move-
ment of fuel in the fuel tank, the warning
light may blinks and the warning buzzer
may come on earlier than usual.
On some models—
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 any authorized Toyota
dealer or repairer, or another duly quali-
fied and equipped professional, as soon
as possible.

GAUGES, METERS AND SERVICE REMINDER INDICATORS125
MS15003
The warning lights indicate the engine
coolant temperature when the engine
switch is on. The engine operating tem-
perature will vary with changes in
weather and engine load.
The engine coolant temperature warning
light will come on when the engine switch
is turned to the “ON” position. After a few
seconds, the light will go off.
Engine coolant temperature is high...
When the engine coolant temperature be-
comes high, the engine coolant tempera-
ture warning light blinks. If the tempera-
ture rises further, the engine coolant
temperature warning light remains on and
at the same time, the “STOP” warning
light blinks. In such cases, the engine is
too hot. If your vehicle overheats, stop the
vehicle and allow the engine to cool down.
Your vehicle may overheat during severe
operating conditions, such as:
DDriving up a long hill on a hot day.
DReducing speed or stopping after high
speed driving.
DIdling for a long period with the air
conditioning on in stop−and−go traffic.
NOTICE
zDo not remove the thermostat from
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.
zDo not continue driving with an
overheated engine. See “If your
vehicle overheats” on page 225 in
Section 4.

Tachometer
MS15004
Left−hand drive vehicles
MS15005
Right−hand drive vehicles
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 over−revving.
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 get segment
into the red zone. This may cause
severe engine damage.
Odometer and trip meter
MS15006
This meter displays the odometer and
trip meter.
1. Odometer—Shows the total distance
the vehicle has been driven.
2. Trip meter—Shows the distance driven
since the last time it was set to zero.
Trip meter data remains stored even
when the electrical power source is
disconnected. Therefore, the stored
driving distance is displayed on the
meter when the electrical power source
is reconnected. However, distances
lessthan1km(1mile)areresetto
zero.
3. Trip meter reset knob—Reset the trip
meter to zero, and also change the
meter display.
To change the meter display, quickly
push and release the knob. The meter
display changes in order from the
odometer to trip meter, then back to
the odometer each time you push.
To reset trip meter to zero, display the
meter reading, then push and hold the
knob until the meter is set to zero.

position.
DWhen the parking brake is applied...
This light comes on for a few seconds
when the engine switch is turned to the
“ON” position even after the parking brake
is released.
DWhen the brake fluid level is low...
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
Have your vehicle checked at any au-
thorized Toyota dealer or repairer, or
another duly qualified and equipped
professional, in the following cases:
DThe light does not come on even if the
parking brake is applied when the en-
gine switch is in the “ON” position.
DThe light does not come on even if the
engine switch is turned on with the
parking brake released.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If either of the following conditions
occurs, immediately stop your vehicle
at a safe place and contact any au-
thorized Toyota dealer or repairer, or
another duly qualified and equipped
professional.
DThe light does not turn off even
after the parking brake is released
while the engine is running.
In this case, the brakes may not
work properly and your stopping
distance will become longer. De-
press the brake pedal firmly and
bring the vehicle to an immediate
stop.
DThe brake system warning light re-
mains on together with the “ABS”
warning light.
In this case, not only the anti−lock
brake system will fail but also the
vehicle will become extremely un-
stable during braking.
(b) Driver ’s Seat Belt Reminder Light
and Buzzer
The light and buzzer act as a reminder to
buckle up the driver ’s seat belt.
Once the engine switch is turned to “ON”
or “START”, the reminder light flashes if
the driver ’s seat belt is not fastened. Un-
less the driver fastens the belt, the light
continues flashing.
If the vehicle speed rises above 20 km/h
(12 mph) with the seat belt unfastened,
the buzzer will sound for 30 seconds.
Then, if the seat belt is still unfastened,
the buzzer will sound in a different tone
for 90 more seconds. Even if the vehicle
speed drops below 20 km/h (12 mph), the
buzzer will continue to sound. To stop the
buzzer, fasten the seat belt. If the buzzer
still sounds, make sure the front passen-
ger ’s seat belt is fastened.

(c) Front Passenger ’s Seat Belt
Reminder Light and Buzzer
The light and buzzer act as a reminder to
have the front passenger buckle up the
seat belt.
Once the engine switch is turned to “ON”
or “START”, the reminder light flashes if
a passenger sits in the front passenger
seat and does not fasten the seat belt.
Unless the front passenger fastens the
belt, the light continues flashing.
If the vehicle speed rises above 20 km/h
(12 mph) with the seat belt unfastened,
the buzzer will sound for 30 seconds.
Then, if the seat belt is still unfastened,
the buzzer will sound in a different tone
for 90 more seconds. Even if the vehicle
speed drops below 20 km/h (12 mph), the
buzzer will continue to sound. To stop the
buzzer, fasten the seat belt. If the buzzer
still sounds, make sure the driver ’s seat
belt is fastened.
If luggage or other load is placed on the
front passenger seat, depending on its
weight and how it is placed on the seat,
built−in sensors in the seat cushion may
detect the pressure, causing the reminder
light to flash and buzzer to sound.
(d) Charging System Warning Light

engine switch is turned to the “ON” posi-
tion, and goes off when the engine is
started.
When there are problems in the charging

safe place and contact any authorized
Toyota dealer or repairer, or another
duly qualified and equipped profes-
sional.
(e) Low Engine Oil Pressure Warning
Light

cause for concern if it then goes out when
the engine is accelerated slightly.
The light may come on when the engine
oil level is extremely low. It is not de-
signed to indicate low engine oil level, and
the engine oil level must be checked us-
ing the level dipstick.

er, if you depress the accelerator pedal
more firmly and slowly, you can drive your
vehicle at low speeds. Have your Toyota
