Automatic speed limiter*
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 Limiter — SL) can be changed to automatic speed limiter.
The automatic speed limiter uses speed information from the Road Sign Information[1] 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.
See also the heading "Limitations for Road sign information".
Is SL or ASL active?
Symbols in the driver display show which speed limiter function is active:
The ASL symbol
The sign symbol (displayed alongside the stored speed, "70", in the centre of the speedometer) can be shown in three colours with the following meanings:
| Colour of sign symbol | Meaning |
|---|---|
| Greenish yellow | ASL is active |
| Grey | ASL has been set in standby mode |
| Amber/Orange | ASL is in temporary standby mode[4] |
Limitations of ASL
Automatic speed limitation takes place using speed information from the RSI[1] function - not from the speed limit road signs that the car passes.
If RSI[1] 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 RSI[1] function can once again interpret and provide speed information to the ASL.
