Automatic Speed Limiter

The Automatic Speed Limiter (ASL) function helps the driver adapt the vehicle's maximum speed to the posted speed limits.

The Speed Limiter (SL1) function can be switched to Automatic Speed Limiter (ASL).

The Automatic Speed Limiter function uses speed information from the Road Sign Information function (RSI) to automatically adapt the vehicle's maximum speed.

 Warning

  • The ASL function is supplementary driver support intended to facilitate driving and help make it safer – it cannot handle all situations in all traffic, weather and road conditions.
  • Even if the driver can clearly see the speed limit sign, the speed information from the Road Sign Information (RSI) function to ASL may be incorrect. In such cases, the driver must intervene and accelerate or brake to an appropriate speed.
  • ASL is not a substitute for the driver's attention and judgment. The driver is always responsible for ensuring the vehicle is driven in a safe manner, at the appropriate speed, with an appropriate distance to other vehicles, and in accordance with current traffic rules and regulations.
  • See also the heading "Road Sign Information limitations".
