Speed limiter

Automatic speed limiter*

Updated 7/23/2018

The automatic speed limiter (Automatic Speed Limiter - ASL) function helps the driver to adapt the car's maximum speed to the speed shown on the road signs.

The speed limiter function (Speed LimiterSL) can be changed to automatic speed limiter.

The automatic speed limiter uses speed information from the Road Sign InformationRoad Sign InformationRSI function to automatically adapt the car's maximum speed.

Warning

The automatic speed limiter function is an aid, and does not work in all driving situations, traffic, weather and road conditions. The driver always bears responsibility for maintaining the correct distance and speed, as well as when the automatic speed limiter is being used.

Even if the driver clearly sees the speed-related road sign, the speed from the Road sign information function many be incorrect - in such cases the driver must intervene him/herself and accelerate or brake to a suitable speed.

Limitations of ASL

Automatic speed limitation takes place using speed information from the RSIRoad Sign InformationRSI function - not from the speed limit road signs that the car passes.

If RSIRoad Sign InformationRSI cannot interpret and provide speed information to the ASL, then the ASL is set in standby mode and changes over to SL. In such cases the driver must intervene and brake to a suitable speed.

The ASL will be reactivated when the RSIRoad Sign InformationRSI function can once again interpret and provide speed information to the ASL.
