Cooling n
Press n to switch on cooling.
Activation is indicated by illumination
of 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.
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 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 to it. If windscreen mists up
from outside, activate windscreen
wiper and deactivate l.
Maximum cooling Briefly open the windows so that hotair can disperse quickly.
■ Switch on cooling n.
■ Air recirculation system 4 on.
