Limitations for speed limiter
Speed limiter (SL1) has certain general limitations.
On steep downhill gradients the speed limiter’s braking effect may be inadequate and hence the stored maximum speed may be exceeded. In this case, the driver is alerted by the message Speed limit exceeded in the driver display.
Note
A text message that the maximum speed is exceeded will be activated if the speed has been exceeded by at least 3 km/h (approx. 2 mph).
