The Permanent Speed Limiter allows the driver to limit the maximum speed of the vehicle (e.g. for winter tires with a lower permissible maximum speed).

The function of the Permanent Speed Limiter is integrated in the ESP control unit (N47-5).

If the vehicle comes close to the set maximum speed the set maximum speed is maintained by means of an engine intervention.

If the set maximum speed is exceeded a warning message is shown in the multifunction display (A1p13) of the instrument cluster (A1).

IMPORTANT When the Permanent Speed Limiter is activated, DISTRONIC or the Variable Speed Limiter can be used (activated) up to the set permanent maximum speed.

Activation/deactivation 

The Permanent Speed Limiter is switched on and off via the left or right switch group in the multifunction steering wheel (S110 and S111).

Here the maximum speed can be set in a menu item of the instrument cluster in 10 km/h steps from 160 km/h to 240 km/h.

IMPORTANT The Variable Speed Limiter and Permanent Speed Limiter have the sales designation "SPEEDTRONIC".
