Humidity sensor
●
In order to detect fog on the wind-
shield, a sensor which monitors the
temperature of the windshield, the sur-
round humidity, etc., is installed.
Follow these points to avoid damaging
●
the sensor:
• Do not disassemble the sensor
• Do not spray the glass cleaner on the
sensor or subject it to strong impacts
• Do not stick anything on the sensor
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.
●
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/recir-
culated air mode switch.

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.
■
When the outside temperature is low
The dehumidification function may not
operate even when "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
accumulate in the air conditioning sys-
tem. This may then cause odor to be
emitted from the vents.
●
To reduce potential odors from occur-
ring:
• It is recommended that the air condition-
ing system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the blower may be
delayed for a short period of time imme-
diately after the air conditioning system is
started in automatic mode.
When parking, the system automatically
●
switches to outside air mode to encour-
age better air circulation throughout the
vehicle, helping to reduce odors that
occur when starting the vehicle.
