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.
