You can set the specified minimum distance for DISTRONIC PLUS by varying the time span between one and two seconds. With this function, you can set the minimum distance that DISTRONIC PLUS keeps to the vehicle in front, dependent on vehicle speed. You can see this distance in the multifunction display.

WARNING
It is up to the driver to exercise discretion to select the appropriate setting given road conditions, traffic, driver's preferred driving style and applicable laws and driving recommendations for safe following distance.

To increase: turn control 2 in direction 3.

DISTRONIC PLUS then maintains a greater distance between your vehicle and the vehicle in front.

To decrease: turn control 2 in direction 1.

DISTRONIC PLUS then maintains a shorter distance between your vehicle and the vehicle in front.

Make sure that you maintain a sufficient and safe distance from the vehicle in front.
Adjust the distance to the vehicle in front if necessary.
