Speed Limit Assist
Function of Speed Limit Assist
Speed Limit Assist detects speed limits with
multifunction camera and displays them in the
driver display and optionally in the head-up dis‐
play. The camera also detects speed limits with a
restriction indicated by an additional sign (e.g.
when wet). The system detects stop signs,
thereby preventing the engine from being
switched off by the ECO start/stop function.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recog‐
nise dangers ( page 192).
