Active Lane Change Assist
▌Function of Active Lane Change Assist
Active Lane Change Assist supports the driver
when changing lanes by applying steering torque
if the driver activates a turn signal indicator.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognize
dangers ( page 176).
/
Assistance when changing lanes is provided if all
the following conditions are met:
You are driving on a freeway or road with mul-
R
tiple lanes in the direction of travel.
The neighboring lane is separated by a broken
R
lane marking.
No vehicle is detected in the adjacent lane.
R
The vehicle speed is between 50 mph
R
(80 km/h) and 110 mph (180 km/h).
Active Lane Change Assist is switched on in
R
the multimedia system.
Active Steering Assist is activated and active.
R
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 signal indi-
cator. This is shown to the driver with a green
arrow next to the ± steering wheel symbol.
The message Lane Change to the Left, for exam-
ple, 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.
As soon as the lane change assistance starts, the
turn signal indicator is automatically activated.
If the assistant display is shown when changing
lanes, an additional arrow appears on it pointing
towards the adjacent lane ( page 187).
/
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. If it is canceled, the
Lane Change Canceled message appears on the
instrument display.
In addition, a warning tone may sound, depending
on the situation.
& WARNING Risk of accident when changing
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 functioning
If the system limitations for Lane Change
Assist have been reached, there is no guaran-
tee that the system will remain active.
