The iDrive combines the functions of a multitude of switches. Thus, these functions can be operated from a central location.
Using the iDrive during a trip
To avoid becoming distracted and posing
an unnecessary hazard to your vehicle's occupants
and to other road users, never attempt to
use the controls or enter information unless traffic
and road conditions allow this.◀
