Climate control115Cooling n
Press 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 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 may inhibit
Autostops.
Stop-start system 3 126.
Air recirculation system 4
Press 4 to activate air recirculation
mode. Activation is indicated by the
LED in the button.
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 to it. If windscreen mists up
from outside, activate windscreen
wiper and deactivate l.
Maximum cooling Briefly open the windows so that hot
air can disperse quickly.
