344 5-2. Using the air conditioning system and defogger HIGHLANDER HV_U Select the S-FLOW mode ■ When the outside temperature exceeds 75°F (24°C) and the air conditioning system is on ● In order to reduce the air condi- tioning power consumption, the air conditioning system may switch to recirculated air mode automati- cally. This may also reduce fuel consumption. ● Recirculated air mode is selected as a default mode when the power switch is turned to ON. ● It is possible to switch to outside air mode at any time by pressing the outside air mode switch. ■ Fogging up of the windows ● The windows will easily fog up when the humidity in the vehicle is high. Turning “A/C” on will dehu- midify the air from the outlets and defog the windshield effectively. ● If you turn “A/C” off, the windows may fog up more easily. ● The windows may fog up if the recirculated 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 recommended 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 recom- mended in preventing dirty air from entering the vehicle interior and helping to cool the vehicle when the outside air temperature is high. ● Outside/recirculated air mode may automatically switch depending on the temperature setting or the inside temperature. ■ Eco air conditioning mode When Eco drive mode is selected using the driving mode select switch, eco air conditioning mode turns on. drive mode is selected, eco air con- ditioning mode may turn off. ■ Operation of the air condition- ing system in Eco drive mode ● In Eco drive mode, the air condi- tioning system is controlled as fol- lows to prioritize fuel efficiency: • Engine speed and compressor operation controlled to restrict heating/cooling capacity • Fan speed restricted when auto- matic mode is selected ● To improve air conditioning perfor- mance, perform the following operations: • Adjust the fan speed • Turn off Eco drive mode ( • Turn off Eco air conditioning mode ● When the driving mode is set to Eco driving mode, the air condi- tioning eco mode will be turned on automatically. Even in this case, the air conditioning eco mode can be turned off by pressing the Eco air conditioning mode switch. ■ When the outside temperature is low The dehumidification function may not operate even when “A/C” is pressed. ■ Ventilation and air conditioning odors ● To let fresh air in, set the air condi- tioning 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. ● To reduce potential odors from occurring: |
