Air conditioning system
In addition to the heating and
ventilation system, the air
conditioning system has controls for:A/C:cooling4:air recirculation
Heated seats 3 48.
Cooling (A/C)
Press A/C 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 A/C again to switch off cooling.
The air conditioning system cools and
dehumidifies (dries) the air when
outside temperature is above a
specific level. 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 an Autostop.
Stop-start system 3 134.
Notice
Air conditioning performance is
reduced when ECO mode has been
activated 3 128.
Air recirculation system 4
Press 4
to activate air recirculation
mode. Activation is indicated by
illumination of the LED in the button.
Press 4 again to deactivate air
recirculation mode.
Climate control117The preselected temperature is
automatically regulated. In Automatic
mode, the fan speed and air
distribution automatically regulate the
air flow.
The system can be manually adapted via the use of air distribution and air
flow controls.
Electronic climate control system is only fully operational when the engine is running.
Automatic mode AUTO Basic setting for maximum comfort: ● Switch on the fan.
● Press AUTO; fan speed, air
distribution, cooling and air
recirculation are regulated
automatically.
● Set the desired temperature.
● Open all air vents.
To switch off the electronic climate
control system, switch off the fan.
Temperature preselection Temperatures can be set to the
desired value.If the minimum temperature is set, the
climate control system runs at
maximum cooling.
If the maximum temperature is set,
the climate control system runs at maximum heating.
Demisting and defrosting the
windows
● Press Ê; LED illuminates in the
button when activated.
● Temperature, air distribution and cooling are regulated
automatically and the fan runs at
high speed.
● Switch on heated rear window Ü

To return to Automatic mode: press Ê or AUTO .
Notice
If Ê is pressed while the engine is
running, an Autostop will be inhibited until Ê is pressed again.
If Ê is pressed while the engine is in
an Autostop, the engine will restart
automatically.

The air conditioning system cools and
dehumidifies (dries) the air when
outside temperature is above a
specific level. Therefore
condensation may form and drip from under the vehicle.
Notice
Air conditioning performance is
reduced when ECO mode has been
activated 3 128.
If no cooling or drying is required
press A/C OFF to switch the cooling
system off, thus saving fuel. LED
illuminates in the button.
To return to Automatic mode: Press
AUTO button.
Air recirculation mode u
Activate or deactivate manual air recirculation mode with u. LED
illuminates in the button when
activated.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.
To return to Automatic mode: Press
AUTO button.
Rear heating system
The rear passenger compartment
heating fan assists air flow to the rear
passenger compartment via the rear
air vents.
The rate of air flow is determined by
the fan. Air temperature is controlled
using the temperature control on the
instrument panel.
Climate control119
To operate the heating fan, press -
to activate the heating fan. The
heating fan is activated if both the
LED of the button and the LED of the
fan control at the roof are not
illuminated.
Set the heating fan y to regulate the
amount of heated air to be flown into
the rear passenger compartment.
Rear air conditioningsystem
The rear air conditioning system is
actuated in conjunction with the front
passenger compartment air
conditioning system.
Rear air conditioning fan switch
The rear air conditioning fan assists
air flow to the rear passenger
compartment via the rear air vents. The rate of air flow is determined by
the fan.
To allow cooled and dehumidified
(dried) air to be distributed:
Press A/C OFF to switch on the air
conditing system. The system is
operating if the LED of the button is
not illuminated.
Press - to activate the rear air
conditioning fan. The fan is activated if both the LED of the button and the
LED of the fan control at the roof are
not illuminated.
120Climate controlSet the fan < to regulate the amount

passenger compartment.
Auxiliary heater Coolant heater
The engine-independent, fuel-
powered coolant heater provides
rapid heating of the engine coolant to
enable heating of the vehicle interior
without the engine running.9 Warning
Do not operate the system when
refuelling, when dust or
combustible vapours are present
or in enclosed spaces (e.g.
garage).
Before starting or programming the
system to start, turn the vehicle's
climate control system to heat, set the
air distribution to V and turn the fan
on.
Switch off when not required. Heating stops automatically after the
programmed runtime. It will also
cease to operate if the vehicle fuel
level drops too low.
During operation, power from the
vehicle battery is used. The driving
time should therefore be at least as
long as the heating time. For short
journey times, check the vehicle
battery regularly and recharge if
necessary.
To ensure efficient performance,
briefly operate the auxiliary heater
once a month.
