considered critical for a possible lane change.
Whenever Lane Change Assist regards the speed
difference and distance of a detected vehicle as
critical, a
weak
light appears in the warning indi-
cator on the relevant mirror.
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
warning stage flashes brightly and briefly several
times, this is an indication for you to check the
driving situation 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
mirror can be adjusted.

Information
– The faster a vehicle is approaching, the earlier
the indicator on the door mirror lights up. You
are always alerted when the Lane Change As-
sist detects a vehicle in the blind spot.
– Changing lanes can already be critical for ve-
hicles approaching at speed if there is still no
indication on the door mirror.
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. 85: 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
changing lanes due to the significant speed differ-
ence, 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 in-
forming you that you may have overlooked a
vehicle.
Vehicles approaching slowly
Fig. 86: Vehicle approaching slowly
A – Warning indicator on door mirror does not
light up
The sensors detect a vehicle approaching at a
slow speed. In the example, the approaching ve-
hicle is in the left lane. Given the small speed dif-
ference and the long distance, this is not indicated
on the door mirror.
B – Warning indicator lights up in information
stage
The distance from the slow approaching vehicle is
now smaller. The warning indicator on the door
mirror lights up. Only when Lane Change Assist re-
gards the speed difference and distance as critical
