can set this speed with the permanent limiter.
Yo u do this by limiting the speed between

te m (/ page186).
Shortly before the set speed is reached, it
appears in the multifunction displa y.When you

Ac tive Steering Assist is only available up to a
speed of 210 km/h. The sy stem helps youto
st ay inthe cent reofthe lane bymeans of mod‐
erate steering inter ventions. Depending on the
speed driven, Active Steering Assist uses the
ve hicles ahead and lane markings as a refer‐

% Depending on the count ry, in the lo wer
speed range Active Steering Assist can use
th e sur rounding traf fic as a refere nce. If nec‐
essar y,Ac tive Steering Assist can then also
