Prewarning
This warning is issued, e.g., when there is the
impending danger of a collision or the distance
to the vehicle ahead is too small.
The driver must intervene actively when there
is a prewarning.
Acute warning with braking function
Warning of the imminent danger of a collision
when the vehicle approaches another object at
a relatively high differential speed.
The driver must intervene actively when there
is an acute warning. If necessary, the driver is
assisted by an automatic braking intervention
in a possible risk of collision.
Acute warnings can also be triggered without
previous prewarning.
Braking intervention The detection of objects can be influenced by
technical system limitations, e. g. pedestrians
or stationary objects. Limitations of the detec‐
tion range and functional restrictions are to be
considered.
The warning prompts the driver himself/herself
to react. During a warning, the maximum brak‐
ing force is used. Premise for the brake boos‐
ter is sufficiently quick and hard stepping on
the brake pedal. The system can assist with
automatic braking intervention if there is risk of
a collision. The intervention can bring the vehi‐
cle to a complete stop.
The braking intervention is executed only if
DSC Dynamic Stability Control is switched on
and Dynamic Traction Control DTC is acti‐
vated.
Above approx. 130 mph/210 km/h the braking
intervention occurs as a brief braking pressure.
No automatic delay occurs.
The braking intervention can be interrupted by
stepping on the accelerator pedal or by ac‐
tively moving the steering wheel.Tow-starting and towing
For towing the vehicle turn, switch off the
Intelligent Safety systems; otherwise malfunc‐
tions of the individual braking systems might
lead to accidents.◀
System limits Be alert
Due to system limitations, warnings may
be not issued at all, or may be issued late or
improperly. Therefore, always be alert and
ready to intervene; otherwise, there is the risk
of an accident.◀
Detection range The system's detection potential is limited.
Thus a warning might not be issued or be is‐
sued late.
E. g. the following situations may not be de‐
tected:▷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.▷Stationary objects.
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, e.g., DSC OFF.▷If the radar sensor is dirty or obscured.Seite 111SafetyControls111

objects.▷When driving very close to the vehicle in
front of you.▷When driving toward bright lights.▷When the windshield in front of the interior
rearview mirror is fogged over, dirty or cov‐
ered with stickers, etc.▷During calibration of the camera immedi‐
ately after vehicle shipment.
Active Blind Spot Detection
The concept
Two radar sensors below the rear bumper
monitor the area behind and next to the vehicle
at speeds above approx. 30 mph/50 km/h.
The system indicates whether there are vehi‐
cles in the blind spot, arrow 1, or approaching
from behind on the adjacent lane, arrow 2.
The lamp in the exterior mirror housing is dim‐
med.
Before you change lanes after setting the turn
signal, the system issues a warning in the sit‐
uations described above.
The lamp in the exterior mirror housing flashes
and the steering wheel vibrates.

HintsPersonal responsibility
The system does not serve as a substi‐
tute for the driver's personal judgment of the
traffic situation.
Be aware of the traffic situation and the vehi‐
cle's surroundings at all times, otherwise acci‐
dents are still possible despite all warnings.◀
