Air conditioning system
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.

Press n to activate air recirculation
mode. The LED in the button
illuminates to indicate activation.
Press n 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.

The electronic climate control system
is only fully operational when the
engine is running.
For correct operation, do not cover
the sensor on the instrument panel.

● 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.

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.

If the minimum temperature of 15 ℃
is set, the electronic climate control
system runs at maximum cooling.
If the maximum temperature of 27 ℃

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.

216Climate controlCombi
Additional air conditioning is supplied to the rear passenger compartment
via the air vents located above the
driver and front passenger
compartment.
With the front passenger
compartment air conditioning system
switched on, adjust the air flow to
select the desired speed.
Ensure the air vents are open when in use, to prevent ice forming in the
system due to lack of air movement.
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.
Note
Depending on version, an additional
coolant heater may be switched on
automatically to speed up heating
when the ignition is on and the
outside temperature is below 5 ℃.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.
Control units
The timer or remote control unit turns the system on and off, and is used to
programme specific departure times.

9 Warning
Do not attach any objects to the
slats of the air vents. Risk of
damage and injury in the event of
an accident.
