Recirculated air mode
First read and observe the introductory information and safety warn-ings
on page 100.
Recirculated air mode prevents polluted air outside the vehicle from getting into
the vehicle, for example when driving through a tunnel or when standing in a traffic jam.

The indicator light in the button goes out.
Recirculated air mode is switched off automatically if the air distribution controlC
» Fig. 107 on page 100 is turned to position . Recirculated air mode can be
switched on again from this setting by repeatedly pressing the symbol button .
WARNINGDo not leave recirculated air mode on over a longer period of time, as “stale”
air can cause fatigue of the driver and passengers, reduce attention levels and
also cause the windows to mist up. The risk of having an accident increases.
Switch off recirculated air mode as soon as the windows start to mist up.

automatic mode
First read and observe the introductory information given on page 103.
The automatic mode is used in order to maintain a constant temperature and to
demist the windows in the interior of the car.
Recommended setting for all periods of the year

Set the required temperature between +18 °C and +26 °C: we recommend 22 °C.
›
Press the button
» Fig. 108 on page 103.

Move the air outlet vents 2 and 3 » Fig. 105 on page 99 so that the air flow is
directed slightly upwards.
After pressing, an indicator light in the top right or left corner of the button
lights up, depending on which mode was last selected.
If the warning light in the top right corner of the button
lights up, the Clima-
tronic operates in “HIGH”-mode.
FThe “HIGH” mode is the standard setting of the Climatronic.
When pressing the button again, the Climatronic switches to “LOW”-mode
and the indicator light in the top left corner lights up. The Climatronic uses only in
this mode the lower blower speed. However taking into account the noise level, this is more comfortable, yet be aware that the effectiveness of the air condition-ing system is reduced particularly if the vehicle is fully occupied.
By pressing the button again, it is changed to “HIGH”-mode.
Automatic mode can be switched off by pressing one of the buttons for the air
distribution or by increasing/decreasing the blower speed.

The indicator light in the button lights up.
If the warning light in the symbol button is lit, the temperature for both sides
cannot be set with the control dial A
. This function can be restored by pressing
the symbol button . The indicator light in the button goes out.
The interior temperature can be set between +18 °C and +26 ℃. The interior tem-
perature is regulated automatically within this range.
If a temperature lower than +18 °C is selected, a blue symbol lights up at the start
of the numerical scale.
If a temperature higher than +26 °C is selected, a red symbol lights up at the start
of the numerical scale.
At both end positions, Climatronic functions at maximum cooling/heating output and the temperature is not regulated.
CAUTION
Lengthy and uneven distribution of the air flow out of the vents (especially
around the feet) and large differences in temperature, for example, when getting
out of the vehicle, can cause susceptible individuals to catch a cold.
Recirculation mode - Version 1
First read and observe the introductory information given on page 103.
Recirculated air mode prevents polluted air outside the vehicle from getting intothe vehicle, for example when driving through a tunnel or when standing in a
traffic jam.
If a considerable increase in concentration of pollutants is recognised by the air quality sensor, recirculated air mode will temporarily be switched off.
If the concentration of pollutants decreases to the normal level, the air distribu-
tion control is automatically switched off so that fresh air can be guided into the
vehicle interior.
In recirculated air mode air is sucked out of the interior of the vehicle and then
fed back into the interior. When the automatic air distribution control is switched
on, an air quality sensor measures the concentration of pollutants in the drawn in
air.
Switching recirculated air mode on›

left side of the
button is illuminated.

also cause the windows to mist up. The risk of having an accident increases.
Switch off recirculated air mode as soon as the windows start to mist up.

The automatic air distribution control operates only if the outside temperature
is higher than approx. 2 °C.

ses blower speed.
If the blower is switched off, the Climatronic system is switched off.

levels and also cause the windows to mist up. The risk of having an accident
increases.■
Do not switch off the Climatronic system for longer than necessary.

The transmitter and the battery are housed in the housing of the remote control. The receiver is located in the interior of the vehicle.
When the battery is fully charged, the range of the remote control is a few hun-
dred metres. Obstacles between the remote control and the vehicle, bad weather
conditions and a weaker battery in the remote control can clearly reduce the range.
To switch the auxiliary heating (aux. heating) on or off, hold the remote control
vertical, with the aerial
A
pointing upwards. The antenna must not be covered
with the fingers or the palm of the hand during this process.
The auxiliary heating can only be switched on/off safely using the radio remote control, if the distance between the radio remote control and the vehicle is at
least 2 m.

109Air conditioning system

For the sake of the environmentDo not warm up the engine while the vehicle is stationary. If possible, start your
journey as soon as the engine has started. Through this the engine reaches its operating temperature more rapidly and the pollutant emissions are lower.
Note
After switching off the ignition, the radiator fan may intermittently continue to
operate for approx. 10 minutes.
Electronic immobilizer
First read and observe the introductory information and safety warn-ings
on page 131.
An electronic chip is integrated in the head of the key. The immobiliser is deacti-
vated with the aid of this chip when the key is inserted in the ignition lock.
The electronic immobiliser is automatically activated when the ignition key is
withdrawn from the lock.
The engine will not start if a non-authorized ignition key is used.
The following message is shown in the information cluster display.

illuminates after the ignition has been switched on. Start
the engine after the warning light
has gone out.
You should not switch on any major electrical components during the heating pe- riod otherwise the vehicle battery will be drained unnecessarily.
