6-1. Using the air conditioning system and defogger
Using automatic mode
■
Fan speed is adjusted automatically according to the temperature setting and the ambi-
ent conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow immediately
after the "AUTO" button is pressed or "AUTO" is selected.
When the outside temperature exceeds 75F (24C) and the air conditioning system
■
is on
In order to reduce the air conditioning power consumption, the air conditioning 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 power switch is turned to
●
ON mode.
It is possible to switch to outside air mode at any time by pressing
●
Fogging up of the windows
■
The windows will easily fog up when the humidity in the vehicle is high. Pressing "A/C"
●
button or selecting "A/C" will dehumidify the air from the outlets and defog the wind-
shield 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.
●
Outside/recirculated air mode
■
When driving on dusty roads such as tunnels or in heavy traffic, set
●
the recirculated air mode. This is effective in preventing outside air from entering the
vehicle interior. During cooling operation, setting the recirculated air mode will also
cool the vehicle interior effectively.
Outside/recirculated air mode may automatically switch depending on the tempera-
●
ture setting or the inside temperature.
When the outside temperature is low
■
The dehumidification function may not operate even when "A/C" is pressed or "A/C" is
selected.
Operation of the air conditioning system in Eco drive mode
■
In the Eco drive mode, the air conditioning system is controlled as follows to prioritize
●
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
• Customize the air conditioning control of Eco drive mode. (P. 596)
