5-1. Using the air conditioning system and defogger
switch.
Defogging the rear window
■
and outside rear view mir-
rors (if equipped), and de-
icing windshield wipers (if
equipped)
Defoggers are used to defog the
rear window and to remove rain-
drops, dew and frost from the
outside rear view mirrors (if
equipped).
The windshield wiper de-icer is
used to prevent ice from building
up on the windshield and wiper
blades.
Press the rear window defog-
ger/outside rear view mirror
defoggers /windshield wiper de-
icer switch.
The defoggers and windshield
wiper de-icer will automatically turn
off after 15 minutes.
When the rear window defog-
ger/outside rear view mirror defog-
gers /windshield wiper de-icer
switch is on, the indicator illumi-
nates on the switch.
Eco air conditioning mode
■
The air conditioning is controlled
with low fuel consumption priori-
tized such as reducing fan
speed, etc.
Select the eco air conditioning
mode switch on the control
screen. (P.352)
When the eco air conditioning
mode is on, the indicator illumi-
nates on the eco air conditioning
mode switch.
■ Fogging up of the windows
● The windows will easily fog up
when the humidity in the vehicle is
high. Turning "A/C" switch on will
dehumidify the air from the outlets
and defog the windshield effec-
tively.
● If you turn "A/C" switch off, the
windows may fog up more easily.
● The windows may fog up if the
recirculated air mode is used.
■ When driving on dusty roads
Close all windows. If dust thrown up
by the vehicle is still drawn into the
vehicle after closing the windows, it
is recommended that the air intake
mode be set to outside air mode
and the fan speed to any setting
except off.
■ Outside/recirculated air mode
● Setting to the recirculated air
mode temporarily is recom-
mended in preventing dirty air
from entering the vehicle interior
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.
When the outside temperature
■
exceeds 75°F (24°C) and the air
conditioning system is on
● In order to reduce the air condi-
tioning power consumption, the air
conditioning system may switch to
recirculated air mode automati-
cally. This may also reduce fuel
consumption.
● Recirculated air mode is selected
as a default mode when the power
switch is turned to ON.
● It is possible to switch to outside
air mode at any time by pressing
the outside/recirculated air mode
