5-1. Using the air conditioning system and defogger
AVALON (U)_(01999-07001)
■ 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:
● When the outside temperature exceeds 68°F (20°C), the air conditioning
system may switch to recirculated air mode automatically. This may also
reduce fuel consumption.
● It is possible to switch to outside air mode at any time by pressing
.
■ Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and
the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after is touched.
■ Fogging up of the windows
● The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the wind-
shield effectively.
● If you turn 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 out-
side/recirculated air mode to the recirculated air mode. This is effective in
preventing outside air from entering the vehicle interior. During cooling oper-
ation, setting the recirculated air mode will also cool the vehicle interior
effectively.
● Outside/recirculated air mode may automatically switch depending on the
temperature setting, outside temperature, pressure, engine coolant temper-
ature or inside temperature.
■ When the outside temperature exceeds 75°F (24°C) and the air condition-
ing system is on (U.S.A. only)
● In order to reduce the air conditioning power consumption, the air condition-
ing system may switch to recirculated air mode automatically. This may also
reduce fuel consumption.
● Recirculated air mode is selected as a default mode when the engine switch
is turned to IGNITION ON mode.
● It is possible to switch to outside air mode at any time by pressing
.
■ When the outside temperature falls to nearly 32F (0C)
The dehumidification function may not operate even when is touched.
