The concept
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.
