When Active Blind Spot Assist is activated,
grey radar waves propagating backwards
appear next to the vehicle in the assistance
display in the multifunction display. Above a
speed of 30 km/h, the colour of the radar
waves in the assistance display changes to
green ;. Active Blind Spot Assist is then
ready for use.
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 will then hear
a double warning tone and red warning
lamp : flashes. If the turn signal remains on,
detected vehicles are indicated by the flash-
ing of red warning lamp :. There are no fur-
ther warning tones.
Course-correcting brake application
If Active Blind Spot Assist detects a risk of a
side impact in the monitoring range, a course-
correcting brake application is carried out.
This is designed to help you avoid a collision.
G WARNING
A course-correcting brake application cannot
always prevent a collision. There is a risk of an
accident.
Always steer, brake or accelerate yourself,
especially if Active Blind Spot Assist warns
you or makes a course-correcting brake appli-
cation. Always maintain a safe distance at the
sides.
If a course-correcting brake application
occurs, red warning lamp : flashes in the
exterior mirror and a dual warning tone
sounds. In addition, display ; underlining
the danger of a side collision appears in the
multifunction display.
In very rare cases, the system may make an
inappropriate brake application. A course-
correcting brake application may be interrup-
ted at any time if you steer slightly in the
opposite direction or accelerate.
The course-correcting brake application is
available in the speed range between
30 km/h and 200 km/h.
Either a course-correcting brake application
appropriate to the driving situation, or none at
all, may occur if:
there are vehicles or obstacles, e.g. crash
R
barriers, on both sides of your vehicle
a vehicle approaches too closely on the
R
side
you have adopted a sporty driving style with
R
high cornering speeds
you clearly brake or accelerate
