4345-3. Using the air conditioning system and defogger
LS460/LS460L_GE (OM50G06E)
■Operation of the air conditioning system in Eco drive mode
●In the Eco drive mode, the air conditioning system is controlled as follows to priori-
tize 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
• Turn off Eco drive mode
■Using the automatic mode
Fan speed is adjusted automatically in accordance with the temperature setting and
ambient conditions. As a result, the following may occur:
●Immediately after the “AUTO” switch is pressed, the fan may stop for a while until
warm or cool air is ready to flow.
●Cool air may flow to the area around the upper body when the heater is on.
■Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high. Selecting
“A/C” on will dehumidify the air from the outlets and defog the windshield effec-
tively.
●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.
■Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the outside/
recirculated air mode button to the recirculated air mode. This is effective in pre-
venting outside air from entering the vehicle interior. During cooling operation, set-
ting the recirculated air mode will also cool the vehicle interior effectively.
●Outside/recirculated air mode may automatically switch depending on the tem-
perature setting or the inside temperature.

cal disability

overcooling.

may cool the occupants excessively or may cause minor burns or overheating.
