When the rear window defogger switch
is on, the indicator illuminates on the
rear window defogger switch.
Vehicles with outside rear view
mirror defoggers
Defoggers are used to defog the
rear window, and to remove rain-
drops, dew and frost from the out-
side rear view mirrors.
Press the rear window and outside
rear view mirror defoggers switch.
The defoggers will automatically turn off
after a while.
When the rear window and outside rear
view mirror defoggers switch is on, the
indicator illuminates on the rear window
and outside rear view mirror defoggers
switch.
■Fogging up of the windows
●The windows will easily fog up when
the humidity in the vehicle is high. Turning “A/C” switch is on will dehu-midify the air from the outlets and
defog the windshield effectively.
●If you turn “A/C” switch is off, the win-
dows may fog up more easily.
●The windows may fog up if the recir- culated air mode is used.
■When driving on dusty roads
Close all windows. If dust thrown up by
the vehicle is still drawn into the vehicle after closing the windows, it is recom-mended that the air intake mode be set
to outside air mode and the fan speed to any setting except off.
■Outside/recirculated air mode
●Setting to the recirculated air mode temporarily is recommended in pre-venting dirty air from entering the
vehicle interior and helping to cool the vehicle when the outside air tempera-ture is high.
●During cooling operation, setting the
recirculated air mode will also cool the vehicle interior effectively.
■When the outside temperature falls to nearly 0°C (32°F)
The dehumidification function may not operate even when “A/C” switch is pressed.
■Ventilation and air conditioning
odors
●To let fresh air in, set the air condition-
ing system to the outside air mode.
●During use, various odors from inside
and outside the vehicle may enter into and accumulate in the air conditioning system. This may then cause odor to
be emitted from the vents.
●It is recommended that the air condi-
tioning system be set to outside air mode prior to turning the vehicle off.

WARNING
■To prevent the windshield from fogging up
Do not use the windshield defogger
switch during cool air operation in extremely humid weather. The differ-ence between the temperature of the
outside air and that of the windshield can cause the outer surface of the windshield to fog up, blocking your
vision.
■When the outside rear view mir-
ror defoggers are operating (if equipped)
Do not touch the outside rear view
mirror surfaces, as they can become very hot and burn you.

6-3. Do-it-yourself maintenance
WARNING
●Do not leave anything that may burn easily, such as paper and
rags, in the engine compartment.
●Do not smoke, cause sparks or
expose an open flame to fuel or the battery. Fuel and battery fumes are flammable.
●Be extremely cautious when work-ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
●Take care because brake fluid can
harm your hands or eyes and dam- age painted surfaces. If fluid gets on your hands or in your eyes, flush
the affected area with clean water immediately.If you still experience discomfort,
consult a doctor.
■When working near the electric
cooling fan or radiator grille
Be sure the engine switch is OFF. With the engine switch in ON, the
electric cooling fan may automatically start to run if the air conditioning is on and/or the coolant temperature is
high. ( P.261)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting in your eyes.
NOTICE
■If you remove the air cleaner fil-ter
Driving with the air cleaner filter removed may cause excessive engine wear due to dirt in the air.
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.If the reservoir needs frequent refill-
ing, it may indicate a serious problem.

If the level is on or below the (LOW)
line, add coolant up to the (FULL)
line. ( P.339)
■Coolant selection
Only use “Toyota Super Long Life Cool-
ant” or a similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with
long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deion-
ized water. (Minimum temperature: - 35°C [-31°F])
For more details about coolant, contact
any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■If the coolant level drops within a
short time of replenishing
Visually check the radiator, hoses,
engine coolant reservoir caps and water pump.If you cannot find a leak, have any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer, test the cap and check for leaks
in the cooling system.
Check the radiator, condenser clear
away any foreign objects. If either
of the above parts is extremely dirty
or you are not sure of their condi-
tion, have your vehicle inspected by
any authorized Toyota retailer or
Toyota authorized repairer, or any
reliable repairer.
WARNING
■When the engine is hot
Do not remove the engine coolant
reservoir cap.
The cooling system may be under pressure and may spray hot coolant if
the cap is removed, causing serious injuries, such as burns.
NOTICE
■When adding coolant
Coolant is neither plain water nor straight antifreeze. The correct mix-
ture of water and antifreeze must be used to provide proper lubrication, corrosion protection and cooling. Be
sure to read the antifreeze or coolant label.
■If you spill coolant
Be sure to wash it off with water to prevent it from damaging parts or
paint.
Checking the radiator, con-
denser
WARNING
■When the engine is hot
Do not touch the radiator or con- denser as they may be hot and cause serious injuries, such as burns.
