Steering assistance when
changing lanes
Principle
The system provides the driver with additional
support when changing lanes on multi-lane
roads.
Operating requirements
▷ Operating requirements of the steering and
lane control assistant are met, see page 229.
▷ Driving on a road with physical barriers.
▷ Lane marking detected.
▷ Lane Change Warning and steering interven‐
tion are switched on, see page 193.
▷ Speed between 70 km/h, approx. 43 mph
and 180 km/h, approx. 110 mph.
Changing lanes
1. Ensure that the traffic situation permits a lane
change.
2. Push and hold the turn indicator lever, see
page 131, in the desired direction as far as
the resistance point to indicate briefly.
After a short period, steering assistance in
the desired direction is noticeable.
After the lane change, the system helps the
driver keep the vehicle in lane.
Cancelling a lane change
If the turn indicator lever is released too soon, the
system helps the driver to keep in the original
lane.
