direction, a warning tone sounds once. The red
warning lamp in the outside mirror flashes. If the
turn signal indicator remains on, all other detec‐
ted vehicles are indicated only by the flashing of
the red warning lamp.
If you overtake a vehicle quickly, no warning is
given.
& WARNING Risk of accident despite Blind
Spot Assist
Blind Spot Assist does not react to vehicles
approaching and overtaking you at a greatly
different speed.
As a result, Blind Spot Assist cannot warn
drivers in this situation.
Always pay careful attention to the traf‐
#
fic situation and maintain a safe dis‐
tance at the side of the vehicle.
Blind Spot Assist and Active Blind Spot Assist
are only aids. They may fail to detect some vehi‐
cles and are no substitute for attentive driving.
Always ensure that there is sufficient distance to
the side for other road users and obstacles.
System limitations
The detection capability of Blind Spot Assist can
be restricted in the following situations:
If the sensors are dirty or covered.
R
When there is poor visibility, e.g. due to fog,
R
heavy rain, snow or spray.
If narrow vehicles are within the monitoring
R
range, e.g. bicycles.
Warnings may be issued in error when driving
close to crash barriers or similar solid lane bor‐
ders. Warnings may be interrupted when driving
alongside long vehicles, for example lorries, for a
prolonged time.
Blind Spot Assist is not operational when reverse
gear is engaged.
Brake application of Active Blind Spot Assist
If Active Blind Spot Assist detects a risk of a side
impact in the monitoring range, a course-cor‐
recting brake application is carried out. This is
designed to help you avoid a collision.
The course-correcting brake application is availa‐
ble in the speed range between approximately
30 km/h and 200 km/h.

correcting brake application.
Always maintain a safe distance at the
#
sides.
& WARNING Risk of accident despite
Active Blind Spot Assist
Active Blind Spot Assist does not react to the
following:
Overtaking vehicles closely on the side,
R
placing them in the blind spot area.
