Using recirculation for long periods
of time could cause the air inside of
the vehicle to become too dry. To
prevent this from happening, after
the inside of the vehicle has cooled,
turn the recirculation mode off.
The air conditioning system
removes moisture from the air, so
water might drip under the vehicle
while idling or after turning off the
engine. This is normal.
@(Recirculation):Press to turn
the recirculation mode on or off. An
indicator light comes on when
recirculation is on. When the engine
is turned off, the recirculation mode
automatically turns off and must be
re-selected when the engine is
turned on again.
This mode recirculates and helps to
quickly cool the air inside the
vehicle. It can be used to prevent
outside air and odors from entering
the vehicle.
The recirculation mode cannot be
used with floor, defrost, or defogging
modes. If recirculation is selected in these modes, the indicator flashes
three times and turns off. The air
conditioning also comes on when
this mode is activated unless the
outside air temperature is less than
4°C (40°F). While in recirculation
mode the windows can fog when
the weather is cold and damp. To
clear the fog, select either the defog
or defrost mode and increase the
fan speed.
