Using automatic mode
■
Fan speed is adjusted automatically according to the temperature setting and the ambi-
ent conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow immediately
after the Automatic mode switch is pressed.
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.
This may also reduce fuel consumption.
Recirculated air mode is selected as a default mode when the engine switch is turned to
●
IGNITION ON mode.
It is possible to switch to outside air mode at any time by pressing the outside/recircu-
●
lated air mode switch.
Fogging up of the windows
■
The windows will easily fog up when the humidity in the vehicle is high. Touching "A/C"
●
on will dehumidify the air from the outlets and defog the windshield effectively.
If you turn "A/C" 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 clos-
ing 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 recommended 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 tempera-
●
ture setting or the inside temperature.
