the freezing point. Therefore
condensation may form and drip from under the vehicle.

124Climate control
If no cooling or drying is required,
switch off the cooling system for fuel
saving reasons. Activated cooling
may inhibit autostops.

recirculation mode. Activation is
indicated by the LED in the button.
Press button 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 s.
Maximum cooling
Briefly open the windows so that hot
air can disperse quickly.
■ Switch on cooling n.
■ Air recirculation system 4 on.
■ Press air distribution switch M.
■ Set temperature control to coldest level.
■ Set fan speed to highest level.
■ Open all vents.
