The Speed Limiter (SL) function can be switched to Automatic Speed Limiter.
Where applicable, ASL uses speed information from the Road Sign Information* system to automatically adapt the vehicle's maximum speed.
Warning
- ASL is a supplemental aid to the driver and does not function in all driving situations or in all traffic, weather or road conditions. It can never replace the driver’s attention to traffic conditions or his/her responsibility for operating the vehicle in a safe manner.
- Even if the driver clearly sees a speed limit sign, the speed information from Road Sign Information to ASL may not be correct. The driver must adapt the vehicle's speed accordingly.

Is SL or ASL active?
The ASL symbol
A road sign symbol (next to the stored speed in the center of the speedometer) can be displayed in three different colors as explained in the following table:
| Road sign symbol's color | Explanation |
|---|---|
| Green/yellow | ASL is active |
| Gray | ASL is in standby mode |
| Amber/orange | ASL is temporarily in standby mode (e.g., because a speed limit sign could not be read) |
ASL limitations
- ASL utilizes the speed limit information provided by the Road Sign Information* system (RSI), not from the speed limit signs that the vehicle passes.
- If RSI cannot provide ASL with speed-related information, ASL will go into standby mode and switch to SL. The driver will have to react and adapt the vehicle's speed.
- ASL will reactivate when RSI is once again able to read a speed limit sign.
