Pollen removal mode
In order to prevent the windshield from fogging up when the outside air is
cold, the following may occur:
• Outside air mode does not switch to recirculated air mode.
• The air conditioning system operates automatically.
• The operation cancels after 1 minute.
In rainy weather, the windows may fog up. Press .
Outside temperature display
In the following situations, the correct outside temperature may not be dis-
played, or the display may take longer than normal to change.
When stopped, or driving at low speeds (less than 25 km/h [16 mph])
When the outside temperature has changed suddenly (at the entrance/
exit of a garage, tunnel, etc.)
Operation of the air conditioning system in Eco drive mode
In the Eco drive mode, the air conditioning system is controlled as follows to
prioritize fuel efficiency:
Engine speed and compressor operation controlled to restrict heating/
cooling capacity
Fan speed restricted when automatic mode is selected
To improve air conditioning performance, perform the following operations:
Adjust the fan speed and temperature
Turn off Eco drive mode (P. 218)
Customize the air conditioning control of Eco drive mode. (P. 548)
When outside air temperature is below 0 C (32 F)
The cooling and dehumidification function may not operate even when
is pressed.

Air conditioning odors
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.
To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic
mode.
Customization
Settings (e.g. switching between outside air and recirculated air mode linked
to “AUTO” switch operation) can be changed.
(Customizable features P. 548)
CAUTION
To prevent the windshield from fogging up
Do not use
during cool air operation in extremely humid weather. The
difference between the temperature of the outside air and that of the wind-
shield can cause the outer surface of the windshield to fog up, blocking your
vision.
NOTICE
To prevent 12-volt battery discharge
Do not leave the air conditioning system on longer than necessary when the
hybrid system is off.

When changing the temperature setting using the steering switches
The temperature will change, however the position of the selection frame on
the air conditioning display will remain the same.
When operating the steering switches (vehicles with head-up display)
The steering switches operation status is displayed on the head-up dis-
play for confirmation purposes. (P. 247)

Rear window and outside rear view mirror defogger switch
Operating conditions
The “POWER” switch is in ON mode.
The outside rear view mirror defoggers
Turning the rear window defogger on will turn the outside rear view mirror
defoggers on.
CAUTION
When the outside rear view mirror defoggers are on
Do not touch the outside surface of the rear view mirrors, as they can
become very hot and burn you.
NOTICE
To prevent 12-volt battery discharge
Do not leave the rear window defogger on longer than necessary when the
hybrid system is off.
Defoggers are used to defog the rear window, and to remove rain-
drops, dew and frost from the outside rear view mirrors.
Turns the rear window and
outside rear view mirror defog-
gers on/off
The defoggers will automati-
cally turn off after approxi-
mately 15 minutes.

CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions.
When working on the engine compartment
Make sure that the indicator on the “POWER” switch and the “READY”
indicator are both off.
Keep hands, clothing and tools away from the moving fan.
Be careful not to touch the engine, power control unit, radiator, exhaust
manifold, etc. right after driving as they may be hot. Oil and other fluids
may also be hot.
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. Fuel fumes
are flammable.
When working near the electric cooling fans or radiator grille
Be sure the “POWER” switch is off.
With the “POWER” switch in ON mode, the electric cooling fans may auto-
matically start to run if the air conditioning is on and/or the coolant tempera-
ture is high. (P. 404)
Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in your eyes.
