Active Blind Spot Assist monitors the area up to
3.0 m behi nd your vehicle and directly next to
your vehicle, as shown in the diagram.
In particular, the detection of obstacles can be
impaired in the following situations:
R dirt on the sensors or obscured sensors
R poor visibility, e.g. due to rain, snow or spray
Vehicles in the monitoring range are then not
reliably indicated.
Active Blind Spot Assist may not detect narrow
vehicles, such as motorcycles or bicycles, or
may only detect them too late.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may be
indicated, especially if the vehicles are not driv-
ing in the middle of their lane. This may be the
case if there are vehicles at the edge of their
lane.
On very wide lanes, vehicles in the lane next to
your vehicle may not be displayed if the vehicles
are too far away.
The nature of the system may result in the fol-
lowing:
R Warnings may be issued in error when you are
driving close to crash barriers or similar solid boundaries
R Warnings may be interrupted when you are
driving alongside particularly long vehicles,
for example lorries, for a prolonged time Indicator and warning display
:
Yellow indicator lamp/red warning lamp
Active Blind Spot Assist is not operational at
speeds of below approximately 30 km/h. Vehi-
cles in the monitoring range are then not indi-
cated.
If Active Blind Spot Assist is switched on, indi-
cator lamp :in the exterior mirrors lights up
yellow up to a speed of 30 km/h. At speeds
above 30 km/h, the indicator lamp goes out and Active Blind Spot Assist is operational.
If a vehicle is detected within the monitoring
range at speeds above 30 km/h, warning
lamp :on the corresponding side lights up red.
This warning lamp always lights up when a vehi- cle enters the blind spot monitoring range from
behind or from the side. When you overtake a
vehicle with a difference in speed of less than
12 km/h, a delayed warning occurs.
The yellow indicator lamp goes out if reverse
gear is engaged. Active Blind Spot Assist is not
operational.
The brightness of the indicator/warning lamps
is adjusted automatically according to the
brightness of the surroundings.
Visual and acoustic collision warning If you switch on the turn signals to change lanes
and a vehicle is detected in the side monitoring range, you receive a visual and acoustic collision
warning. You then hear a double warning tone
and red warning lamp :flashes. If the turn sig-
nal remains on, detected vehicles are indicated
by the flashing of red warning lamp :. No fur-
ther warning tones are issued.
Course-correcting brake application
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. Driving systems
