The automatic speed limiter function (ASLAutomatic Speed Limiter) can be activated and deactivated as a supplement to the speed limiter (SLSpeed Limiter).

The Speed Sign Assist button is located in the function view of the centre display.

To activate the automatic speed limiter:

Press the Speed Sign Assist button.

ASL is set in standby mode, a green indicator appears on the button, and the driver display shows a sign symbol in the centre of the speedometer.

Press the steering wheel button .

ASL is activated with the car’s current speed.


  • If the Automatic Speed Limiter function is activated, road sign information is shown in the driver display even if RSI

    is not activated.
  • To remove road sign information from the driver display, you must deactivate both Automatic Speed Limiter and RSI.
  • When the Automatic Speed Limiter function is activated but RSI is deactivated, no warnings are given from RSI. RSI must also be activated in order to receive warnings.

Deactivate ASL

To deactivate the automatic speed limiter:

Tap on the Speed Sign Assist button in the function view.

ASL is deactivated and the button's indication becomes GREY - SL is activated instead.


After switching from ASL to SL the car will no longer follow the signed speed limit but only the maximum speed stored in memory.
