dehumidifies (dries) when outside
temperature is above a specific level. Therefore condensation may form
and drip from under the vehicle.
If no cooling or drying is required,
switch off the cooling system for fuel
saving reasons.
When the cooling system is switched
off, no engine restart will be
requested by the climate control
system during an Autostop.
Exception: defrost system is activated and outside temperature above 0 °C

recirculation mode. The LED in the
button illuminates to indicate
activation.
Press 4 again to deactivate
recirculation mode.9 Warning
The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling the air humidity increases, so the
windows may mist up from inside.
The quality of the passenger
compartment air deteriorates,
which may cause the vehicle
occupants to feel drowsy.
In warm and very humid ambient air conditions, the windscreen may mist
up from outside, when cold air is
directed towards it. If windscreen
mists up from outside, activate
windscreen wiper and deactivate l.
Automatic air recirculation
An air humidity sensor switches
automatically to external air if internal air humidity is too high.
