Press button n to switch on cooling.
Activation is indicated by the LED in
the button. Cooling is only functional
when the engine is running and
climate control fan is switched on.
Press button n again to switch off
cooling.
The air conditioning system cools and
dehumidifies (dries) as soon as the
outside temperature is slightly above
the freezing point. 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
might inhibit Autostops.

recirculation mode. Activation is
indicated by the LED in the button.
Press button 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 might mist up from outside, when cold air is
directed to it. If windscreen mists up
from outside, activate windscreen
wiper and deactivate s.
Maximum cooling

air can disperse quickly.
