Warning systems
Introduction
Driver messages about the distance
warning
The side assist function monitors the blind spot
and the traffic behind your vehicle in the neigh-
bouring lanes and helps you when changing lane.
If the system detects an approaching object
which it judges to be critical, the warning signal
1 lights up on the exterior mirror on the corre-
sponding side of the vehicle.
If is displayed in the event of a fault, the dis-
tance warning functions are unavailable or re-
stricted.
If
and a driver message about the active front
assist are displayed in the event of a fault, the
distance warning functions are unavailable or re-
stricted.
Driving situations
– Your vehicle is being overtaken by another vehi-
cle. The faster this vehicle approaches from be-
hind, the earlier the warning signal will appear
on the exterior mirror.
A driver message indicating the cause and possi-
ble remedy may appear for some of the displays.
To display the driver messages again, open the
notification centre on the centre display. The
weather conditions may not be good enough, or a
sensor may be obstructed. Clean the area in front
of the sensors ðpage 133. Try switching on the
system later or after the vehicle is next switched
on.
– There are vehicles travelling at a similar speed
in the next lane. The warning signal will appear
on the exterior mirror by the time the detected
object is in your blind spot.
– You are overtaking another vehicle slowly. If the
speed differential between the two vehicles is
not greater than approx. 15 km/h, the warning
signal will appear on the exterior mirror.
If a fault persists, drive to a qualified workshop
soon and have it rectified.
Information mode
Side assist
If you have not yet operated a turn signal, the
system informs you of objects which it judges to
be critical at speeds of above approx. 10 km/h.
Using the side assist
The system informs you of objects which it judg-
es to be critical by lighting up the warning signal
1 on the exterior mirror on the appropriate side.
The intensity of the warning signal in this infor-
mation mode is kept relatively low, so that it
does not distract you while you are looking at the
road in front.

mirror
Warning mode
As soon as you activate a turn signal, the system
warns you of objects which it judges to be critical
by flashing the warning signal on the correspond-
ing exterior mirror.
Depending on the vehicle equipment, if other
driver assist systems detect that you are in dan-
ger of leaving your lane, the warning signal may
flash and a tone may sound to warn you of ob-
jects which the system judges to be critical, even
if you have not activated a turn signal. The sys-
tem may initiate a corrective steering input as an
