mode on will activate the dehumidification function. ■
Operation of the air conditioning system in Eco drive mode
In 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 capac-
ity ●
Fan speed restricted when automatic mode is selected
To improve air conditioning performanc e, perform the foll owing operations:●
Adjust the fan speed ●
Turn off Eco drive mode ■
When the outside temperature falls to nearly 32  F (0  C)
The dehumidification function may not oper ate even when is pressed or “A/C” is
selected. ■
Ventilation and air conditioning odors ●
To let fresh air in, set the air conditioning system to the outside air mode. ●
During use, various odors from inside and outside the vehicle may enter into and accu-
mulate in the air conditioning system. This may then cause odor to be emitted from the
vents. ●
To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air mode prior
to turning the vehicle off.
• The start timing of the blower may be dela yed for a short period of time immediately
after the air conditioning system is started in automatic mode.■
