The air conditioning system cools and
dehumidifies (dries) as soon as the
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. Activated cooling
may inhibit Autostops.

mode. The LED in the button
illuminates.
Press 4 again to deactivate air
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
