BMW Z4 Roadster Owner's Handbook Manual page 177

If a lane marking is crossed in the speed range
up to 210 km/h, approx. 130 mph, the system in‐
tervenes not only by vibrating but also with a
brief active steering intervention. The system
thereby helps to keep the vehicle in lane.
Safety notes
WARNING
The system does not relieve you of your per‐
sonal responsibility to assess the course of the
road and the traffic situation. There is a danger
of accidents. Adapt your driving style to the
traffic conditions. Observe the traffic situation
and intervene actively if the situation warrants it.
In the event of a warning, do not move the
steering wheel with unnecessary force.
WARNING
Displays and warnings do not relieve you of
your personal responsibility. System limitations
can mean that warnings or system responses
are not issued or are issued too late, incorrectly
or without justification. There is a danger of ac‐
cidents. Adapt your driving style to the traffic
conditions. Observe the traffic situation and in‐
tervene actively if the situation warrants it.
Operating requirements
The lane marking must be detected by the cam‐
era in order for the Lane Departure Warning to
be active.
