Deactivated hands-off detection will prevent DISTRONIC system features from functioning, including warnings to grab the steering wheel and calling first responders as part of the Active Emergency Stop Assist, which can increase the risk of a crash or injury.

Due to a software error in the hand detection control unit, the hands-off detection might not detect when the driver's hands are away from the steering wheel when using the Active Distance Assist DISTRONIC system.

What to do: Book this in with a dealer now. It affects a safety system.
