Storing settings
With the memory function, you can store up to three different settings, e.g. for three different people.
The following settings are stored as a single memory preset:
• position of the seat, backrest and head
restraint
• driver's side: steering wheel position
• driver's side: position of the exterior
mirrors on the driver's and front-passenger
sides
WARNING 
Do not activate the memory function while
driving. Activating the memory function while
driving could cause the driver to lose control
of the vehicle.
► Adjust the seat.
► On the driver's side, adjust the steering wheel and the exterior mirrors.
► Press memory button M and one of the storage position buttons 1, 2 or 3 within three seconds.
The settings are stored in the selected preset position. A tone sounds when the settings have been completed.
