Cooling A/C
Press A/C to switch on cooling. The
LED in the button illuminates to
indicate activation. Cooling is only
functional when the engine is running and climate control fan is switched on.
Press A/C 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. The LED in the button
illuminates to indicate activation.
Press 4 again to deactivate air
recirculation mode.9 Warning
Driving with recirculation mode for
a prolonged period of time can
make you sleepy. Periodically turn to the outside air mode for fresh
air.
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. 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
mists up from outside, activate
windscreen wiper and deactivate V.
Maximum cooling Briefly open the windows so that hot
air can disperse quickly.

Temperature preselection
Set temperature to the desired value. It is indicated on the display in thetemperature control.
For reasons of comfort, change
temperature only in small increments.
If the minimum temperature Lo is set,
the climate control system runs at
maximum cooling, if cooling A/C is
active.
If the maximum temperature Hi is set,
the climate control system runs at
maximum heating.
Recommended temperature is 22 °C .Note
If A/C is switched on, reducing the
set cabin temperature can cause the
engine to restart from an Autostop or inhibit an Autostop.
