Air conditioning system
Additional to the heating and

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) the air when
outside temperature is a little above
the freezing point. Therefore
condensation may form and drip from under the vehicle.
If no cooling or drying is required,
switch the cooling system off to save
fuel.
Note
If the climate control is set to
maximum cooling while the ambient temperature is high, an Autostop
may be inhibited until the required
temperature in the passenger
compartment has been reached.If the climate control is set to
maximum cooling while the engine is
in an Autostop, the engine may
restart automatically.

Air recirculation system Press u to activate air recirculation
mode. The LED in the button
illuminates to indicate activation.
Press u 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. The quality
of the passenger compartment air
deteriorates, which may cause the vehicle occupants to feel drowsy.
Maximum cooling
Briefly open the windows so that hotair can disperse quickly.
Climate control119Automatic modeBasic setting for maximum comfort: ● Press AUTO ("AUTO" appears in
the display).
● Set desired temperature (the temperature appears in the

● Open all air vents.
During automatic mode, the settings for fan speed, air distribution, air
conditioning and air recirculation are
automatically regulated by the system
and are not shown on the display.
Temperature preselection Temperatures can be set to the
desired value with the two buttons
below the display.
For reasons of comfort, change
temperature only in small increments.red:warmblue:cold
Heating will not be fully effective until
the engine has reached normal
operating temperature.
If the minimum temperature of 15 ℃
is set, the electronic climate control
system runs at maximum cooling.
If the maximum temperature of 27 ℃
is set, the electronic climate control
system runs at maximum heating.
Note
If the temperature is to be reduced
for climate comfort reasons, an
Autostop can be inhibited or the
engine will restart automatically
when cooling is switched on.

Rear heating system
If the engine is switched off, the rear
compartment can be heated by the
additional heating, through low level
vents.
By programming values using the
control panel, the user can adjust the
time, day and temperature settings.
Heating will cease to operate if the
vehicle fuel level drops too low.
During operation, power from the
vehicle battery is used. For short
journey times, check the vehicle
battery regularly and recharge if
necessary.
Note
If the rear heating system is
activated while the engine is
running, an Autostop will be
inhibited.
To ensure efficient performance, the
low level air vents in the rear
passenger compartment must not be
obstructed.
