warning light in the button goes out.Rear window heater– Press button . Further information page 71.Auxiliary heating (auxiliary heating)– Press the button in order to directly switch on/off the auxiliary heating
(auxiliary heating and ventil ation. Further information page 117.
The set temperature will be automatically maintained other than when the
control dial is on the extreme right or extreme left position:
Extreme right position - full heating,
Extreme left position - full cooling,
The blower should aways be on to prevent the windows from misting up.Note
The whole heat output will be needed to unfrost the windscreen and side windows.
No warm air will be fed to the footwell. Th is can lead to restriction of the heating
comfort.
The used air streams out through the air removal openings in the luggage compart-
ment.
If the cooling system has not been switched on for a lengthy period, odours may
be produced at the evaporator because of deposits. Switch the cooling system on at
least once a month for approximately 5 minutes at the highest blower stage - also
during the cold season of the year - in order to avoid such odours. Also open a window
for a short time.
Please refer to the information regarding recirculated air mode page 113.

Note
Below the top row of buttons is located the interior temperature sensor. Do not glue
or cover over the sensor, otherwise it could have an unfavourable effect on the
Climatronic.Automatic mode
The automatic mode is used in order to maintain a constant tempera-
ture and to demist the windows in the interior of the car.Switching automatic mode on– Set a temperature between +18 °C and +26 °C.
– Move the air outlet vents 2 and 3 page 110, fig. 119 , so that the air flow is
directed slightly upwards.
– Press the button . In the right or left top corner a warning light lights up, depending on which unit was last selected.
If the warning light in the top right corner of the button lights up, the
Climatronic operates in “HIGH” mode. The “HIGH” mode is the standard setting of the
Climatronic.
When pressing again the button , the Climatronic changes into the “LOW” mode
and the warning 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 conditioning system is
reduced particularly if the vehicle is fully occupied.
By pressing again the button , you change into the “HIGH” mode. The automatic mode is switched off by pres
sing the button for the air distribution or
increasing or decreasing the blower speed. The temperature is nevertheless
regulated.
switching cooling on and offswitching cooling on and off– Press the button . The warning light lights up in the button.
– When you again press the switch , the cooling system is switched off. The warning light in the button goes out. Only the function of the ventilation remains
active when no lower temperature than the outside temperature can be reached.Setting temperatureYou can separate the interior temperature for the left and right side separately.
– You can set the temperature for both sides after switching on the ignition with the control dial .
– If you wish to set the temperature for the right side, turn the control dial . The warning light in the button lights up, this indicates that differing tempera-
tures for the left and right side can be set.
If the warning light in the button ligh ts up, the temperature for both sides
cannot be set with the control dial . You can reinitiate this function by pressing the
button . The warning light in the button which indicates the possibility to set
differing temperatures for the left and right side, goes out.
You can set the interior temperature between +18°C and +26°C. The interior temper-
ature is regulated automatically within this range. If you chose a temperature lower
than +18°C, a blue symbol lights up at the start of the numerical scale. If you chose a
temperature higher than +26°C, a red symbol lights up at the end of the numerical
scale. In both limit positions the Climatro nic operates at maximum cooling or heating
capacity, respectively. The temperatur e is not controlled in this case.
Lengthy and uneven distribution of the air flow out of the vents (in particular at the leg
area) and large differences in temperature, for example when getting out of the vehicle,
can result in chills in sensitive persons.
