Warning with braking function
Note
Adapting your speed and driving style
The warning does not relieve the driver
of the responsibility to adapt his or her driving
speed and style to the traffic conditions.◀
Display
If a collision with a vehicle detected in this way
is imminent, a warning symbol appears on the
instrument cluster and in the Head-up Display.
Symbol Measure
The vehicle lights up red: prewarn‐
ing.
Increase braking and distance.
The vehicle flashes red and an
acoustic signal sounds: acute warn‐
ing.
You are requested to intervene by
braking or making an evasive ma‐
neuver.
Braking intervention
The warning prompts the driver himself to in‐
tervene. During a warning, the maximum brak‐
ing force is used. A prerequisite for the brake
booster is a sufficiently fast and sufficiently
strong actuation of the brake pedal. In addition,
if there is a risk of collision, the system can as‐
sist with a slight braking intervention. The in‐
tervention can bring a vehicle traveling at slow
speed to a complete stop.
Manual transmission: During a braking inter‐
vention up until reaching a complete stop, the
engine may be shut down.
The braking intervention is executed only if
DSC Dynamic Stability Control is switched on
and Dynamic Traction Control DTC is acti‐
vated.
The braking intervention can be interrupted by
pressing on the accelerator pedal or by actively
moving the steering wheel.
Tow-starting and towing
When tow-starting and towing the vehi‐
cle, switch off the Intelligent Safety systems;
otherwise, improper behavior of the braking
function of individual systems could result in
an accident.◀
System limits
Be alert
Due to system limitations, warnings may
be not be issued at all, or may be issued late or
improperly. Therefore, always be alert and
ready to intervene; otherwise, there is the dan‐
ger of an accident occurring.◀
Detection range
The system's detection capabilities are limited.
This may result in the warning not being is‐
sued or being issued late.
For example, the following situations may not
be detected:
▷ Slow moving vehicles when you approach
them at high speed.
▷ Vehicles that suddenly swerve in front of
you or sharply decelerating vehicles.
▷ Vehicles with an unusual rear appearance.
▷ Two-wheeled vehicles ahead of you.
▷ Pedestrians.
Functional limitations
The system may not be fully functional in the
following situations:
▷ In heavy fog, rain, sprayed water or snow‐
fall.
▷ In tight curves.
▷ If the driving stability control systems are
limited or deactivated, for example, DSC
OFF.
