Speed Limit Assist
Function of Speed Limit Assist
% The availability of the following function is
country-dependent.
Speed Limit Assist detects speed limits with
multifunction camera 1 and displays them in
the instrument cluster and optionally in the
head-up display. The camera also detects speed
limits with a restriction indicated by an addi‐
tional sign (e.g. in wet conditions). The system
detects stop signs, thereby preventing the
engine from being switched off by the ECO
start/stop function.
Speed Limit Assist is only an aid. The driver is
responsible for keeping a safe distance to the
vehicle in front, for vehicle speed and for braking
in good time.
