Speed limit detection
The concept
Speed limit detection
Speed limit detection shows the current maxi‐
mum permitted speed in the instrument clus‐
ter. The camera in the area of the interior mir‐
ror detects traffic signs at the edge of the road
as well as variable overhead sign posts. Traffic
signs with extra symbols for wet road condi‐
tions, etc. are also detected and compared
with the vehicle's onboard data, such as for the
rain sensor, and will be displayed depending
on the situation. The system takes into ac‐
count the information stored in the navigation
system and also displays speed limits present
on routes without signs.
Information WARNING
The system does not release from the
personal responsibility to correctly assess visi‐
bility and traffic situation. There is risk of an ac‐
Seite 86ControlsDisplays86

The driver must intervene actively when there
is an acute warning. If necessary, the driver is
assisted by a minor automatic braking inter‐
vention in a possible risk of collision.
Acute warnings can also be triggered without
previous forewarning.
Braking intervention
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 some braking intervention if there is a risk of a
collision. At low speeds vehicles may thus
come to a complete stop.
Manual transmission: During a braking inter‐
vention up to a complete stop, the engine may
be shut down.
The braking intervention is executed only if ve‐
hicle stability has not been restricted, e.g. by
deactivating the DSC Dynamic Stability Con‐
trol.
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.
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 the field of view of the camera in the mir‐
ror is dirty or obscured.▷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.
