Warning with braking function
Display
If there is a risk of collision with a detected vehi‐
cle, a warning symbol is shown in the instrument
cluster and, if applicable, in the Head-Up Display.
Symbol Measure
Symbol illuminates red: advance
warning.
Brake and increase the distance.
Symbol flashes red and an acoustic
signal sounds: acute warning.
Brake and perform an evasive ma‐
noeuvre, if necessary.
Advance warning
An advance warning is shown, for example if a
danger of collision is anticipated or there is a very
short distance to a vehicle ahead.
The driver must intervene personally if there is
an acute warning.
Acute warning with braking function
An acute warning is given when the vehicle is ap‐
proaching another object at a high differential
speed and there is an immediate risk of a colli‐
sion.
The driver must intervene personally if there is
an acute warning. Depending on the driving sit‐
uation, the acute warning may be supported by a
brief jolt in the brakes.
If the warning time setting is "late", the jolt does
not occur.
If necessary, the system can also assist by brak‐
ing the vehicle automatically if there is a risk of a
collision.
An acute warning can be triggered even without
a previous advance warning.
Brake intervention
The warning prompts the driver to intervene ac‐
tively. When the brake is operated during a warn‐
ing, the maximum necessary braking force is ap‐
plied. Braking assistance requires that the brake
pedal is depressed sufficiently quickly and firmly
beforehand.
The system can also assist by braking the vehi‐
cle automatically if there is a risk of a collision.
At low speeds, the vehicle can be braked to a
stop.
City braking function: brake intervention takes
place at up to approx. 80 km/h, 50 mph.
With radar sensor: brake intervention takes place
at up to approx. 250 km/h, 155 mph.
At speeds above approx. 210 km/h, 130 mph,
the braking intervention takes the form of a brief
jolt. There is no automatic deceleration.
The brakes are only applied if driving stability has
not been impaired, for example by deactivation of
Dynamic Stability Control DSC.
Braking can be discontinued either by depress‐
ing the accelerator pedal or by actively moving
the steering wheel.
The detection of objects may be limited. Take
into account the detection range limits and the
functional limitations.
System limits
Safety note
WARNING
The system may not respond at all, or may re‐
spond too late, incorrectly or without justifica‐
tion due to limits of the system. There is a dan‐
ger of accidents or damage to property.
Observe the information on the system limits
and intervene actively if necessary.
