Situation-dependent brake force boosting
Situation-dependent brake force boosting may
intervene at speeds starting from approximately
7 km/h in the following situations:
R
Vehicles travelling in front: up to approximately
250 km/h
R
Stationary vehicles: up to approximately
80 km/h
R
Crossing vehicles: no reaction
R
Cyclists ahead: up to approximately 80 km/h
R
Moving pedestrians/crossing cyclists: up to
approximately 60 km/h
R
Stationary pedestrians: no reaction
Cancelling a brake application of Active Brake
Assist
You can cancel a brake application of Active Brake
Assist at any time by:
R
Fully depressing the accelerator pedal or with
kickdown.
R
Releasing the brake pedal.
Active Brake Assist may cancel the brake applica-
tion when one of the following conditions is fulfil-
led:
R
You manoeuvre to avoid the obstacle.
R
There is no longer a risk of collision.
R
An obstacle is no longer detected in front of
your vehicle.
System limits
Full system performance is not yet available for a
few seconds after switching on the vehicle or after
driving off.
The system may be impaired or may not function in
the following situations:
R
In snow, rain, fog or heavy spray.
R
If the sensors are dirty, misted up, damaged or
covered.
R
If the sensors are impaired due to interference
from other radar sources, e.g. strong radar
reflections in multi-storey car parks.
R
If a loss of tyre pressure or a defective tyre has
been detected and displayed.
R
In complex traffic situations where objects
cannot always be clearly identified.
R
If pedestrians or vehicles move quickly into the
sensor detection range.
R
If pedestrians are hidden by other objects.
R
If the typical outline of a pedestrian cannot be
distinguished from the background.
R
If a pedestrian is not detected as such, e.g.
due to special clothing or other objects.
R
In bends with a narrow radius.

It is recommended that Active Brake Assist is
always left activated.

To activate/deactivate: press the
a
button.
The distance warning function and the autono-
mous braking function of Active Brake Assist
are deactivated or activated.
When the functions are deactivated, the
æ
symbol appears in the assistance graphic in
the instrument cluster display.
The next time the vehicle is started, Active Brake
Assist is automatically activated.
Function of Adaptive Brake Lights
Adaptive Brake Lights warn following traffic in an
emergency braking situation with the following sig-
nals:
R
By flashing the brake lamps
R
By activating the hazard warning lights
If the vehicle is braked sharply from speeds above
50 km/h, the brake lamps flash rapidly. This pro-
vides traffic travelling behind you with an even
more noticeable warning.
If the vehicle is travelling at speeds of more than
70 km/h at the beginning of the brake application,
the hazard warning lights switch on once the vehi-
cle is stationary. When pulling away again, the haz-
ard warning lights switch off automatically at
approximately 10 km/h.
You can also switch off the hazard warning lights
using the hazard warning button (

Function of cruise control
Cruise control accelerates and brakes the vehicle
automatically in order to maintain a previously
stored speed.
