You can ventilate the vehicle before you start driving. To do this, the SmartKey is used to carry out the following functions simultaneously:
• unlock the vehicle
• open the side windows
• open the hinged side windows
• open the sliding sunroof or the panorama
roof with power tilt/sliding panel and the
roller sunblinds
• switch on the seat ventilation for the
driver's seat
The convenience opening feature can only be operated using the SmartKey. The SmartKey must be close to the driver's door handle.
