Lane Change Assist (LCA)
Rear collision warning
A
If the radar sensors in the rear of the vehicle detect
B
vehicles traveling behind, the system calculates the
C
probability of a rear-end collision.
If a collision risk is detected, the emergency flasher
D
comes on to alert the driver in the vehicle traveling
E
behind to the imminent danger situation.
In this case, the emergency flasher could flash faster
F
than it normally would when switched on manually.

Display elements
H
Lane Change Assist provides information using two
I
indicator stages - an information stage and a warn-
J ing stage - which are activated as appropriate, de-
pending on whether or not the turn signal was set.
K
Information stage
L
While the turn signal is not on, Lane Change Assist
M
provides information about detected vehicles that it
N
regards as critical in the event of a possible lane
change. The indicator on the relevant mirror lights up
O
dimly.
P
Warning stage
Q
If the turn signal is on and Lane Change Assist has
detected a vehicle on this side that it regards as
R
critical, the warning indicator on the door mirror on
S
this side will flash brightly and briefly several times.
This is an indication for you to check the driving sit-
T
uation by looking in the door mirror and looking over
U
your shoulder.

symbol Fig. 88: 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
A fast approaching vehicle – in the left lane in the
example – is detected. This vehicle is already con-
sidered critical for changing lanes due to the signifi-
cant speed difference, even though it is still a good
distance away. The warning indicator on the door
mirror lights up.
