System limits
Information WARNING
The system can react incorrectly or not
at all due to the system limits. There is risk of
accidents or risk of property damage. Observe
the information regarding the system limits
and actively intervene, if needed.◀
Detection range
The system's detection potential is limited.
Thus a system reaction might not come or
might come 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.
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.▷If, depending on the vehicle equipment
version, the field of view of the camera in
the mirror or the radar sensor is dirty or ob‐
scured.▷Up to 10 seconds after the start of the en‐
gine, via the Start/Stop button.▷During calibration of the camera immedi‐
ately after vehicle delivery.▷If there are constant blinding effects be‐
cause of oncoming light, e. g., from the sun
low in the sky.
Warning sensitivity
The more sensitive the warning settings are,
for example the warning time, the more warn‐
ings are displayed. However, there may also be
an excess of false warnings.
Collision warning with
braking function
The concept The system can help prevent accidents. If an
accident cannot be prevented, the system will
help reduce the collision speed.
The system sounds a warning before an immi‐
nent collision and actuates brakes independ‐
ently if needed.
The automatic braking intervention may be
executed with maximum braking force and for
a brief period only as necessary.
If the vehicle is equipped with Active Cruise
Control with Stop&Go, the front-end collision
warning is controlled via the cruise control ra‐
dar sensor in conjunction with a camera.
The front-end collision warning is available
even if cruise control has been deactivated.
With the vehicle approaching another vehicle
intentionally, the collision warning and braking
are delayed in order to avoid false system re‐
actions.
General information
The system issues a two-phase warning of a
possible danger of collision with vehicles at
speeds above approx. 3 mph/5 km/h. Time of
warnings may vary with the current driving sit‐
uation.

the system.
Information WARNING
Indicators and warnings do not relieve
the driver from personal responsibility. Due to
system limits, warnings or reactions of the sys‐
tem may not be output or they may be output
too late or incorrectly. There is risk of an acci‐
dent. Adjust the driving style to the traffic con‐
ditions. Watch traffic closely and actively inter‐
vene in the respective situations.◀
WARNING
Due to system limits, individual functions
can malfunction during tow-starting/towing
with the Intelligent Safety systems activated,
e.g., approach control warning with light brak‐
ing function. There is risk of an accident.
Switch all Intelligent Safety systems off prior to
tow-starting/towing.◀

of a collision. The intervention can bring the
vehicle to a complete stop.
The braking intervention is executed only if ve‐
hicle stability has not been restricted, e.g. by
deactivating the DSC Dynamic Stability Con‐
trol.
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.
Object detection can be restricted. Limitations
of the detection range and functional restric‐
tions are to be considered.

PDC Park Distance Control
The concept PDC is a support when parking. When you
slowly approach an object in the rear - or also
in the front of the vehicle if the feature is availa‐
ble - then the object is reported through:▷Signal tones.▷Visual display.
General information
Ultrasound sensors in the bumpers measure
the distances from objects.
The maneuvering range, depending on the ob‐
stacle and environmental conditions, is approx.
6 ft/2 m.
An acoustic warning is first given with the fol‐
lowing circumstances:
▷By the front sensors and the two rear cor‐
ner sensors at approx. 24 inches/60 cm.▷By the rear middle sensors at approx.
5 ft/1.50 m.▷When a collision is imminent.
