Automatic speed limiter

Activate/deactivate Automatic Speed Limiter

Updated 7/23/2018

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

Activate ASL

P5-1646-Knapp Automatisk fartbegränsare

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. In this situation, settings for RSI cannot be adjusted either - to be able to adjust settings as well as receive warnings, RSI must be activated.

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.
