button for at least 2 seconds. It will then remain on until the ignition is switched off.Residual heat
You can press and hold the ON/OFF button when the ignition is switched off to activate the "residual heat" function Fig. 1. The system will then heat the interior using the remaining heat in the engine coolant.
Air outlets
The thumbwheels can be used to open and close the air outlets in the centre and on either side of the dashboard and rear centre console and the outlets in the door pillars. The lever in the centre of the outlets can be used to adjust the direction of air flow.
For reasons of safety you should not leave the air recirculation switched on for too long. This mode prevents fresh air from entering the vehicle, so the windows can mist over if the air cooling is switched off. Bad visibility can cause an accident.
Caution!
To avoid damaging the heating elements of the seat heating, please do not kneel on the seat or apply sharp pressure at a single point.
Note
- The heating only operates when a sensor registers the weight of the occupant in the seat. Any heavy items you place on the seats could also cause the seat heating to come on. The seats can also be pre-heated for about 10 minutes. After this time the seat heating will automatically switch off if the seat is not occupied.
- The rear A/C control console* cannot be operated if the electric child protection* is switched on or the safety switch is pressed in. In this case the display of the air conditioner for the rear cabin will show lines like this "---".
