Observe the notes on driving systems and your
responsibility; you may otherwise fail to recog‐
nize dangers (/ page 172).
Assistance when changing lanes is provided if all
the following conditions are met:
R
You are driving on a freeway or road with
multiple lanes in the direction of travel.
R
The neighboring lane is separated by a bro‐
ken lane marking.
R
No vehicle is detected in the adjacent lane.
R
The driven speed is between 50 mph
(80 km/h) and 110 mph (180 km/h).
R
Active Lane Change Assist is switched on in
the multimedia system.
R
Active Steering Assist is activated 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 next to the ± steering wheel
symbol. The Lane Change to the Leftmessage,
for example, also appears. If Active Lane Change
Assist has been activated with the turn signal
indicator but a lane change is not immediately
possible, a gray arrow 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 185)
If a lane change is not possible, the arrow is
faded out after a few seconds and a new lane
change must be initiated. An immediate lane
change is only possible on freeway sections
without speed limits.
If the system is impaired, Active Lane Change
Assist may be canceled. The Lane Change Can-
celed message appears in the multifunction dis‐
play.
In addition, a warning tone may sound.

WARNING Risk of accident when chang‐
ing lane to an occupied adjacent lane
Lane Change Assist cannot always clearly
detect 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 neighboring 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.
