The PR-SAFE braking system was installed only on Mercedes S-Class (W221) with Dystronik Plus. This system warns the driver of the risk of collision by means of sound and light signals. If the distance from 30 km/h to the front of the vehicle is too small, the warning lamp shall be used on the instrument panel. If the distance is reduced very quickly, there is an audible intermittent sound. It is also possible to stop the car at speeds from 7 to 200 km/h, if the driver and the front passenger are belted by safety-belts.

Due to the fact that the system may not function correctly in complex road situations (especially in the city), it may sometimes be necessary to disable it. To temporarily stop the system, you can do the following:

  • It's hard to push the gas pedal.
  • Turn kick-down mode on.
  • Release the brake pedal.

To turn off the system completely, you must:

Select the "right" or "left" arrows on the handlebar to the left of the "Auxiliary Systems" menu.

  • Up or down arrows, select " Preface. a torm. PRE-SAFE. "
  • Press OK.
  • Once the "Off System" appears on the screen, click OK again.
