Lane Change Assist (LCA)
150
Information
The radar sensors cover the adjacent lane to the left
and right. Other lanes are not covered by the radar
sensors.
Information and warning stage
Lane Change Assist has two indicator levels that are
activated as appropriate, depending on whether or
not the turn signal has been set.
Information stage
While the turn signal is not on, Lane Change Assist
provides information about detected vehicles that it
regards as critical in the event of a possible lane
change. The indicator on the respective mirror al-
ways comes on dimly when the speed difference
and the distance of the detected vehicle are re-
garded as critical by Lange Change Assist.
Warning stage
If the turn signal is on and Lane Change Assist has
detected a vehicle on this side that it regards as
critical, the warning indicator on the door mirror on
this side will start to flash brightly . When the warn-
ing stage flashes brightly and briefly several times,
this is an indication for you to check the driving sit-
uation again by looking in the door mirror and looking
over your shoulder.
Adjusting display brightness of Lane Change
Assist
The brightness of the indicator for the information
and warning stage is automatically adjusted ac-
cording to the ambient brightness. The basic
brightness of the warning indicator on the door mir-
ror can also be adjusted.

Lane Change Assist
Information
– The faster a vehicle is approaching, the earlier
the warning indicator on the door mirror lights
up. You are always alerted when Lane Change
Assist detects a vehicle in the blind spot.
– Changing lanes can already be critical for ve-
hicles approaching at speed if there is still no
warning activated on the door mirror.
– On vehicles with other assistance systems, the
warning indicator on the door mirror can flash on
briefly several times even if the turn signal is not
on. If Lane Keep Assist detects that your vehicle
is veering out of your lane towards a vehicle on
the adjacent lane, Lane Change Assist alerts you
to the possible danger by flashing on briefly and
brightly several times.
Driving situations
The following driving situations describe possible
scenarios and the associated Lane Change Assist
and Rear Turn Assist warning indicators.
Vehicles approaching fast
Fig. 98: Vehicle approaching at speed
A – Warning indicator on door mirror does not light
up
The sensors have not detected a vehicle. There is no
indication on the door mirror.
B – Warning indicator lights up in information stage
The sensors detect a fast approaching vehicle. In the
example, the approaching vehicle is in the left lane.
This vehicle is already considered critical for chang-
ing lanes due to the significant speed difference,
even though it is still a good distance away. The
warning indicator on the door mirror lights up.
C – Warning indicator flashes in warning stage
If the turn signal is switched on in driving situation B ,
the warning indicator on the door mirror flashes
briefly several times. Lane Change Assist is inform-
ing you that you may have overlooked a vehicle.
