The yellow indicator lamp goes out if reverse
gear is engaged. Active Blind Spot Assist is not

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
:
. There are
no further warning tones.
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.
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 mir-
ror and a dual warning tone sounds. In addition,
display
;
underlining the danger of a side col-
lision appears in the multifunction display.
In very rare cases, the system may make an
inappropriate brake application. A course-cor-
recting brake application may be interrupted at
any time if you steer slightly in the opposite
direction or accelerate.
The course-correcting brake application is avail-
able 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:
R
there are vehicles or obstacles, e.g. crash
barriers, on both sides of your vehicle
R
a vehicle approaches too closely on the side
R
you have adopted a sporty driving style with
high cornering speeds
R
you clearly brake or accelerate
R
a driving safety system intervenes, such as
ESP
®
or PRE-SAFE
®
Brake
R
ESP

is deactivated
R
a loss of tyre pressure or a defective tyre is
detected
