Priorities 

If, within the left multifunction steering wheel button group (S110) or the right multifunction steering wheel button group (S111) several buttons are pressed simultaneously, the instrument cluster (A1) will always only activate one function. As a result, the different functions have different priority ranks.

Allocation of priority ranks within the right multifunction steering wheel button group (S111):

• Fanfare horn push-button (S111s5)
• Accept/terminate phone call button (S111s3)
• Button + and -, setting of specific functions and volume control (S111s1)

Allocation of priority ranks within the left multifunction steering wheel button group (S110):

• Fanfare horn push-button (S110s5)
• System selection button (S110s3)
