Automatic mode
Standard setting for all seasons.Switching on automatic mode
– Select a temperature between +18°C (64°F) and +29°C (86°F).
– Press the button
⇒page 158, fig. 130 .The automatic mode maintains a constant temperature inside the vehicle and
dehumidifies the air. Air temperature, air delivery and air distribution are
regulated automatically to reach the desired interior temperature as quickly
as possible, and then to maintain this temperature. The system automatically
compensates for any variations in the outside temperature and for the effect
of direct sunlight.
The automatic temperature regulation only operates at temperature settings
between +18°C and +29°C. If a temperature below +18°C is selected, LO
appears on the display. If a temperature is selected which is higher than
+29°C, the display will show HI. In the maximum and minimum settings, the
climate control operates continuously with maximum cooling or heating output and the temperature is not regulated automatically. The temperature
is not regulated.
Note
By keeping the button on the driver side pressed for several seconds,
the temperature of the passenger side can be set to the temperature of the
driver side or vice versa. The display indicates the new temperature value.Selecting the temperature
Separate temperatures can be selected for the driver and
front passenger sides.– Press the or buttons below the displays
⇒page 158,
fig. 130 until the desired temperature is selected for the driver
side or front passenger side.The currently selected temperature setting is shown in the display above the
buttons.
By keeping the button on the driver side pressed for several seconds,
the temperature of the passenger side can be set to the temperature of the
driver side or vice versa. The display indicates the new temperature value. The
previous temperature setting can be restored by resetting the display on the

Deactivating air recirculation mode
– Press the button again or
– Press the button or
–Press button .In this setting, the air in the vehicle is constantly recirculated. We recommend
using the air recirculation mode in the following circumstances:
•When driving through a tunnel or in traffic congestions, to prevent
exhaust gas entering the interior of the vehicle.WARNING
Do not drive for too long with the air recirculation mode enabled because,
if the compressor is disconnected, the windscreen may mist up because no
fresh air is entering the interior of the vehicle, with the subsequent risk of
accidents.ECON Mode (economy)
ECON mode helps save fuel.– To activate, press the button ⇒page 158, fig. 130 .
– To deactivate, press the button again or select the button.Air cooling is disconnected in ECON mode. The heating and the blower are
adjusted automatically. “ECON” stands for “Economy”. Disconnecting air
cooling (compressor) reduces fuel consumption.
Please note that the interior temperature must not be lower than the outside
temperature in ECON mode. The blower does not cool or dehumidify the air in
the interior. The windows could therefore mist up.
In diesel vehicles, the auxiliary heater is switched off in ECON mode to save
fuel.

due to a defect in one of the air conditioner components. If a malfunction
should occur, please contact a specialised workshop.
Air recirculation: automatic activation*
If the outside air is polluted by diesel and petrol emissions,
an air quality sensor in the vehicle will automatically switch
on the air recirculation.Activating air recirculation mode
– Press the button
⇒fig. 131 .
Deactivating air recirculation mode
– Press the button again or
– Press the button or – Press button .
The automatic air recirculation mode should normally be left switched on at
all times.
The system is ready to operate approx. 30 seconds after the engine ignition
key has been turned. During this initial period, fresh air is fed into the vehicle.
If the
air purity sensor in the air conditioner detects a certain concentration
of fumes in the outside air, the control unit will either pass the incoming air
through the pollution filter or automatically switch on the air recirculation. If
there is a high concentration of pollution in the outside air, the air conditioner
automatically switches to air recirculation and the supply of air from the
outside is cut off. As soon as the level of pollution decreases, air is fed into
the vehicle from the outside again.
The automatic air recirculation operates for a maximum period of 12 minutes.
If the windows mist up when the automatic air recirculation is on, press the button immediately.
The automatic air recirculation switches itself off under certain circumstances
(for instance if or is selected). In “ECON” and at temperatures lower
than approx. 8°C below zero, the automatic air recirculation mode is limited
to 12 seconds.Switching the temperature displa y from °C to °F and vice versa
The temperature display can be switched from °C (degrees
Celsius) to °F (degrees Fahrenheit) and vice versa.– Press and hold the button for air recirculation mode and
briefly press the plus button of the left-hand temperature
