Solar Ventilation System
: If equipped
The Solar Ventilation System uses energy provided by solar panel
built into the roof to operate a fa n contained within the air condition-
ing system, allowing ventilation of the vehicle interior when the vehi-
cle is parked in direct sunlight.
■ Activating the Solar Ventilation System
With the “POWER” switch in
ON mode, turn on the ventila-
tion switch.
Off
On
Turn the “POWER” switch off.
After approximately 1 minute, outside air mode will be selected
and the air vents will be put into upper body mode.
After approximately 10 minutes, the ventilation operation will
commence.
The ventilation operation will be canceled if the “POWER”
switch is turned to ON mode or the ventilation switch is turned
off.

■Operating conditions
The Solar Ventilation System may not operate under the following circum-
stances due to a lack of power from the solar panel:
●Low amount of sunlight
● Ever when a part of the solar panel is cast by a shadow.
● Ever when a part of the solar panel is covered by fallen leaves or dirt.
● The solar panel is not at a high temperature.
■ Before using the Solar Ventilation System
Remove dirt or fallen leaves from the solar panel in order to ensure sufficient
electrical output.
■ Efficient use of the So lar Ventilation System
Efficient control of temperature increase can be achieved by using the sys-
tem in conjunction with the Remote Air Conditioning System. ( P. 342)
■ When using the Sola r Ventilation System
● Make sure that the “POWER” switch is in ON mode when turning the
ventilation switch on. If the ventilation switch is turned on while the
“POWER” switch is OFF, the air mode and the status of the air vents will
remain unchanged.
● If the Solar Ventilation System is not needed, be sure to turn the ventila-
tion switch off.
Dirty air and exhaust fumes from other vehicles may be drawn from out-
side. Also, use in winter may cause heated interior air to leave the vehi-
cle, thus leading to a drop in temperature.
■ Sounds when using the Solar Ventilation System
If the amount of sunlight is insufficient, you may hear a sound coming from
the air conditioning system. This is the sound of a control function to pre-
serve the fan and does not indicate a malfunction.

CAUTION
■Solar Ventilation System precautions
●Do not use the system if people are inside the vehicle.
The Solar Ventilation System is not intended to ensure the performance of
the air conditioning system. Do not leave children or pets in the vehicle.
The temperature of the interior will remain high, possibly resulting in heat-
stroke, dehydration, or even death.
● This system should be used only for the relief of discomfort when entering
the vehicle, and should not be used for other purposes.

Remote Air Conditioning System
■Operating conditions
The system will only operate if all of the following conditions are met:
●The shift position is in P.
● The “POWER” switch is OFF.
● All doors are closed.
● The hood is closed.
● The brake pedal is not being depressed.
● The air conditioning is not set to “HI”.
: If equipped
The Remote Air Conditioning Syst em uses electrical energy stored
in the hybrid battery (traction batt ery) and allows the air conditioning
to be operated by remote control.
■ Before leaving the vehicle
Check the temperature setting of the air conditioning system.
The Remote Air Conditioning System will operate in accordance with
the temperature settings of the air conditioning system.
■Activating the Remote Air Conditioning System
Press and hold the to
operate the Remote Air Condi-
tioning System.
The system will shut off if a
door is opened.
The system can be stopped by
pressing the twice.

■Using the Remote Air Conditioning System effectively
Efficiency can be increased by using the system in conjunction with the
Solar Ventilation System. ( P. 339)
■ When leaving the vehicle
●Check that the headlights are switched to either off or “AUTO”.
● Check that the wiper switch is turned off.
● Check that all windows are closed.
■ Remote Air Conditioning System automatic shut-off
The system will automatically shut off under the following conditions:
●About 3 minutes have passed since operation began
● Any one of the operating conditions is not met
The system may also shut off if the charge level of the hybrid battery (trac-
tion battery) drops to low. ( P. 42)
■ Conditions affecting operation
The system may not start in the following situations:
●The charge level of the hybrid battery (traction battery) is low ( P. 42)
● The air conditioning temperature is set at a high level or outside tempera-
ture is low
● When the vehicle has been left parked for a number of days
● When the hybrid system is cool (for example, after being left for a long
time in low temperatures)

■Security feature
Any unlocked doors will be automatically locked when the system is operat-
ing. The buzzer will beep and the emergency flashers flash when the doors
have been locked or the system has been turned off.
(The doors locked: Once; The system turned off: Twice)
■ Conditions affecting operation

CAUTION
■Precautions for the Remote Air Conditioning System
●Do not use the system if people are in the vehicle.
• Even when the system is in use, the internal temperature may still
reach a high level due to features such as the automatic shut-off. Chil-
dren and pets left inside the vehicle may suffer heatstroke or dehydra-
tion, or could result in death or serious injury.
• The wipers can be operated during system operation. Children or pets left inside the vehicle may mistakenly operate these and cause an acci-
dent.
● Depending on the surrounding environment, signals from the wireless
switch may transmit further than expected. Pay appropriate attention to
the vehicle’s surroundings and use the switch only when necessary.
● Turn the wipers off. If the Remote Air Conditioning System operates while
the wiper switch is in the on position, the wipers may operate and objects
may get caught in the wiper blades.
● Do not operate the if the hood is open. The air conditioning may
operate unintentionally and objects may be drawn into the electrical cool-
ing fan.
NOTICE
■To prevent the hybrid battery (tractio n battery) from being discharged
through incorrect operation
Use the only when necessary.

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.
