and helping to cool the vehicle
when the outside air temperature
is high.
●Outside/recirculated air mode may
automatically switch depending on
the temperature setting or the
inside temperature.
■Operation of the air condition-
ing system in Eco air condition-
ing mode
●In Eco air conditioning mode, the
air conditioning system is con-
trolled as follows t o prioritize fuel
efficiency:
• Heater and compressor operation controlled to restrict heating/cool-
ing capacity
• Fan speed restr icted when auto-
matic mode is selected
●To improve air co nditioning perfor-
mance, perform the following
operations:
• Turn off eco air conditioning mode ( P.237)
• Adjust the fan speed
■When the outside temperature
falls to nearly 32°F (0°C)
The dehumidification function may
not operate even when “A/C” switch

■Ventilation and air conditioning
odors
●To let fresh air in, set the air condi-
tioning system to the outside air
mode.
●During use, various odors from
inside and outside the vehicle may
enter into and a ccumulate 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 out-
side air mode prior to turning the
vehicle off.
• The start timing of the blower may
be delayed for a short period of time immediately after the air con-
ditioning system is started in auto-
matic mode.
●When parking, the system auto-
matically switches to outside air
mode to encourage better air cir-
culation throughout the vehicle,
helping to reduce odors that occur
when starting the vehicle.
