●When the outside te mperature is low,
heating may feel insufficient due to
restricted operation of the air condi -
tioning. Heating cannot be performed when it is -10°C (14° F) or less as the
gasoline engine cannot be started
during “My Room Mode”. If heating is desired, stop charging and remove
the AC charging cable from the vehi -
cle.
■When driving o n dusty roads
Close all windows. If dust thrown up by
the vehicle is still d rawn 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 recir culated air mode
temporarily is recommended in pre - venting dirty air from entering the
vehicle interior and helping to cool the
vehicle when the ou tside air tempera- ture is high.
●Outside/recirculated air mode may automatically switch depending on the
temperature setting or the inside tem-
perature.
■Operation of the air conditioning system in Eco drive mode
●In Eco drive mode, the air conditioning system is controlled as follows to pri -
oritize fuel efficiency:
