General notes
Thermatic is only operational when the engine is running. Optimum operation is only achieved when you drive with the side windows and sliding/tilting sunroof*/panorama sliding sunroof* closed.
You can allow the air-conditioning system to adjust automatically or you can adjust it manually.
 | |
|
Ventilate the vehicle for a brief period during warm weather, e.g. using the summer opening feature more. This helps you to achieve the desired interior temperature more quickly.
|
The integrated filter filters out most particles of dust and completely filters out pollen.
 | |
|
A clogged filter reduces the amount of air supplied to the vehicle interior. For this reason, you should always observe the interval for replacing the filter, which is specified in the Service Booklet. As it depends on environmental conditions, e.g. heavy air pollution, the interval may be slightly shorter than stated in the Service Booklet.
|
 | Risk of accident |
|
Follow the settings recommended on the following pages for heating or cooling. The windows could otherwise mist up. This may prevent you from observing the traffic conditions, thereby causing an accident.
|
Activating/deactivating Thermatic
Thermatic is only operational when the engine is running.
|
To activate: press the button.
|
| |
The indicator lamp in the button goes out. The previously selected settings come into effect again.
|
or |
|
Press the button.
|
| |
The indicator lamp in the button is lit. Airflow and air distribution are set to automatic mode.

|
| |
The indicator lamp in the button is lit.
|
 | |
|
Select this setting when you drive with the side windows or the sliding/tilting sunroof*/panorama sliding sunroof* open, for example.

Only select this setting briefly when the side windows and the sliding/tilting sunroof*/panorama sliding sunroof* are closed, otherwise the windows may mist up.
|
Controlling the air conditioning automatically
 | |
|
If you have set the air-conditioning system to automatic, you only need to set the temperature. In automatic mode, the airflow and air distribution do not need to be adjusted. The cooling with dehumidification function is switched on in automatic mode. If necessary, cooling with dehumidification can be deactivated.
|
|
Make sure that the key is in position 2 in the ignition lock.
|
|
Set the desired temperature.
|
|
To activate: press the button.
|
| |
The indicator lamp in the button is lit. Airflow and air distribution are set to automatic mode.
|
|
To deactivate: press the button.
|
| |
The indicator lamp in the button is off. Automatic air distribution and airflow are deactivated.
|
Setting the temperature
Different temperatures can be set for the driver's and front-passenger sides.
 | |
|
If you turn the temperature thumbwheel on one side of the vehicle fully to the right or left, you will increase or reduce the temperature on the other side of the vehicle at the same time.
|
Setting the air distribution manually
You can also direct the airflow manually for the entire vehicle.
The symbols for the air distribution have the following meanings:
|

The indicator lamp in the button goes off. The automatic control is deactivated and the air distribution is controlled according to the selected setting.
|
Setting the airflow manually
You can also set the airflow manually for the entire vehicle.
Mono function
You can use the mono function to adopt the settings configured for temperature and air distribution on the driver's side for the front-passenger side.
|
To activate: press the button.
|
| |
The indicator lamp in the button lights up.
|
|
To deactivate: press the button.

|
 | |
|
Do not make any other settings when the demisting function is activated.
|
You can use the following settings to demist the windscreen, e.g. when it is covered with frost:
|
To activate: press the button.
|
| |
The indicator lamp in the button is lit.
-
Cooling with dehumidification on
-
High airflow
-
High temperature
-
Air distribution to the windscreen and front side windows
-
Air-recirculation mode off
|
 | |

You can change the settings for temperature and airflow. The other settings of the demisting function are retained.
|
Windows misted up
Windows misted up on the inside
|
Activate automatic mode more.
|
If the windows are still misted up:
|
Activate the demisting function more.
|
Windscreen misted up on the outside
Air-recirculation mode
You can deactivate the flow of fresh air if unpleasant odours are entering the vehicle from outside. No more fresh air will be taken in and the air inside the vehicle will be recirculated.
 | Risk of accident |
|
At low outside temperatures, only switch over to air-recirculation mode briefly. Otherwise, the windows could mist up, thus impairing visibility and endangering you and others. This may obstruct your view of the traffic conditions, thereby causing an accident.
|
|
To activate: press the button.
|
| |
The indicator lamp in the button is lit.
|
 | |
|
Air-recirculation mode is activated automatically at high outside temperatures. When air-recirculation mode is activated automatically, the indicator lamp in the button goes off.
Outside air is added after about 30 minutes.
|
|
To deactivate: press the button.
|
| |
The indicator lamp in the button is off.
|
 | |
|
Air-recirculation mode switches off automatically:
-
after approximately five minutes at outside temperatures below approximately 5 °C
-
after approximately five minutes if the cooling with dehumidification function is deactivated
-
after approximately 30 minutes at outside temperatures above approximately 5 °C
|
Air-recirculation mode with the convenience opening/closing feature
 | Risk of injury |
|
Make sure that nobody can become trapped between the side window and the door frame as the side windows are opened and closed. Do not place objects or lean against the side window when it is being opened or closed. You or the objects could be drawn in or become trapped between the side window and the door frame as the window moves. If there is a risk of entrapment, release the button. If necessary, press the switch that stops, opens or closes the side window in the opposite direction.
Make sure that nobody can become trapped when you open or close the sliding/tilting sunroof*/panorama sliding sunroof*. If there is a risk of entrapment, release the button. If necessary, press the switch that stops, opens or closes the sliding/tilting sunroof* or panorama sliding sunroof* in the opposite direction.
|
|
Convenience closing: press and hold the button until the side windows and the sliding / tilting sunroof*/panorama sliding sunroof* close.
|
| |
The indicator lamp in the button is lit. Air-recirculation mode is activated.
|
|
Convenience opening: press and hold the button until the side windows and the sliding / tilting sunroof*/panorama sliding sunroof* open.
|
| |
The indicator lamp in the button is off. Air-recirculation mode is deactivated. The side windows and the sliding/tilting sunroof* or panorama sliding sunroof* are in their previous positions.
|
 | |
|
If you open the side windows or the sliding/tilting sunroof* or panorama sliding sunroof* manually after closing using the convenience closing feature, it will remain in this position when opened using the convenience opening feature.
|
Cooling with air-dehumidification
 | Risk of accident |
|
If you turn off cooling with dehumidification, the vehicle will not be cooled or dehumidified during warmer weather conditions. The windows could mist up more quickly. This may prevent you from observing the traffic conditions, thereby causing an accident.
|
 | Environmental note |
|
The cooling system uses the refrigerant R134A. This refrigerant does not damage the earth's ozone layer.
|
 | |
|
Condensation may drip from the underside of the vehicle when Thermatic is in cooling mode.
|
Cooling with dehumidification is operational when the engine is running, and cools according to the interior temperature selected. The air inside the vehicle is also dried, thereby preventing the windows from misting up.
|
To activate: press the button.
|
| |
The indicator lamp in the button is lit.
|
|
To deactivate: press the button.
|
| |
The indicator lamp in the button is off. The cooling with dehumidification function has a delayed switch-off feature.
