Automatic Speed Limiter (ASL)*

The Automatic Speed Limiter (ASL) reads road signs and adapts the vehicle's maximum speed to the posted speed limits.

The Speed Limiter function can be switched to Automatic Speed Limiter.

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 colorExplanation
Green/yellowASL is active
GrayASL is in standby mode
Amber/orangeASL is temporarily in standby mode (e.g., because a speed limit sign could not be read)

Limitations

Adjusting a set speed is done first when the vehicle passes a speed limit sign. If a speed limit sign cannot be read (e.g., because it is twisted, damaged, faded, dirty, covered by snow, etc.) ASL will go into standby mode because the system will not have "seen" the speed posted on the sign (SL will activate). The driver will have to react and adapt the vehicle's speed. ASL will reactivate when the vehicle passes a speed limit sign that the system can read.
