z 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 z
To improve air conditioning performance,
perform the following operations:
• Adjust the fan speed and temperature
• Turn off Eco drive mode (refer to
“Owner ’s Manual”.)
z Unlocking the vehicle using an electronic
key and turning the “START STOP
ENGINE” <“POWER”> switch to IGNI-
TION ON mode will recall that key’s
registered air conditioning settings.
z When the “START STOP ENGINE”
<“POWER”> switch is turned off, the cur-
rent air conditioning settings will automati-
cally be registered to the electronic key
that was used to unlock the vehicle.
The system may not operate correctly if
more than one electronic key is in the vicin-
ity or if the smart access system with push
button start is used to unlock a passenger
door.
Settings for the electronic key and the cor-
responding door can be changed. Contact

zIn 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.
z Recirculated air mode is selected as a
default mode when the “START STOP
ENGINE” <“POWER”> switch is turned to
IGNITION ON mode.
z It is possible to switch to outside air mode at
any time by pressing the air intake control
button.
z In automatic mode, the system detects
exhaust gas and other pollutants and auto-
matically switches between outside air and
recirculated air modes.
When the dehumidification function is off,
and the fan is operating, turning automatic
mode on will activate the dehumidification
function. z
In order to prevent the windshield from fog-
ging up when the outside air is cold, the fol-
lowing may occur:

recirculated air mode.
• The dehumidification function operates.
• The operation cancels after approxi- mately 1 minute.
z In rainy weather, the windows may fog up.
Press the windshield air flow button.
z In extremely humid weather, the windows
may fog up.

side temperature may not be displayed, or
the display may take longer than normal to
change.
• When stopped, or driving at low speeds
(less than 12 mph [20 km/h])
