NOTICE
■Humidity sensor
● Do not spray the glass cleaner on the sensor or subject it to strong impacts
● Do not stick anything on the sensor
■ To prevent 12-volt battery discharge
Do not leave the air conditioning syst em on longer than necessary when the
hybrid system is off.
■ Air outlets
The air outlets become hot when used for heating. Therefore, use caution
and adjust the air outlets accordingly.
In order to detect fog on the windshield, a
sensor which monitors the temperature
of the windshield, the surround humidity,
etc. is installed. ( P. 513)
Follow these points to avoid damaging
the sensor:
● Do not disassemble the sensor

■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 Remote Air Conditioning System cannot be used for approximately 3
minutes and a half after the power switch is turned off.
■Remote Air Conditioning System automatic shut-off
The system will automatically shut off under the following conditions:
●About 10 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 (traction
battery) drops to low.
■Conditions affecting operation
The system may not start in the following situations:
●The charge level of the hybrid battery (traction battery) is low
●The outside temperature is extremely low
●When the hybrid system is cool (for example, after being left for a long time
in low temperatures)
■Windshield defogger
When defogging the windshield using the Remote Air Conditioning System,
defogging may be insufficient due to the power being restricted more than
during normal air conditioning operation. Also, the outside of the windshield
may fog up due to the outside temperature, humidity or air conditioning set
temperature.
■Using the heater via the Remote Air Conditioning System
When the outside heat exchanger becomes frosted over, heating perfor-
mance may decline due to automatically switching to the frost removal opera-
tion.
■Security feature
Any unlocked doors will be automatically locked when the system is operat-
ing. The emergency flashers flash to indicate that the doors have been locked
or the system has been turned off.
(The doors locked: Once; The system turned off: Twice)

Stop the vehicle in a safe place and turn off the air conditioning
system, and then stop the hybrid system.
If you see steam:
