R
Active Steering Assist is switched on and
active.
If no vehicle is detected in the adjacent lane and
a lane change is permitted, the lane change
begins after the driver has activated the turn sig‐
nal indicator. This is shown to the driver with a
green arrow 2 next to the steering wheel sym‐
bol. The Lane change to the left message also
appears, for example. If Active Lane Change
Assist has been activated with the turn signal
indicator but a lane change is not immediately
possible, a grey arrow 1 appears next to the
steering wheel symbol, which remains green.
When the lane change assistance starts, the turn
signal indicator is automatically activated along
with the display in the multifunction display.
If the assistance graphic is shown when chang‐
ing lanes, the lane change display appears with
an additional arrow pointing towards the adja‐
cent lane (
/
page 217).
If a lane change is not possible, the arrow fades
out after a few seconds and a new lane change
must be initiated. An immediate lane change is
only possible on motorway sections without
speed limits.
If the system is impaired, Active Lane Change
Assist may be cancelled. If it is cancelled, the
Lane change cancelled message appears in the
multifunction display and a warning tone sounds.
& WARNING Risk of accident from chang‐
ing lane to an occupied adjacent lane
Lane Change Assist cannot always detect
clearly if the adjacent lane is free.
The lane change might be initiated although
the adjacent lane is not free.
#
Before changing lanes, make sure that
the neighbouring lane is free and there
is no danger to other road users.
#
Monitor the lane change.
&
WARNING Risk of accident if Lane
Change Assist unexpectedly stops func‐
tioning
If the system limitations for Lane Change
Assist have been reached, there is no guar‐
antee that the system will remain active.
Lane Change Assist cannot then assist you
by applying steering torques.
#
Always monitor the lane change and
keep your hands on the steering wheel.
Observe the traffic conditions and steer
and/or brake if necessary.
