pre-speed regulation
Introduction to the topic
· Always use current navigation data.
· Always keep in mind the maximum speed allowed.
In the case of speed limitations that are not
included in the navigation data, the maximum
permissible speed may be exceeded.
Please also note the safety-relevant information on ACC
ÿ p. 165.
Pre-speed regulation adapts the speed to the speed limits
detected and to the layout of the road (curves, junctions,
roundabouts, etc.).
Limitations of speed
preregulation
Pre-speed regulation is an additional function of ACC and uses
the traffic sign detection system ÿ p. 29 and the navigation data
from the infotainment system.

Pre-speed regulation is available depending on equipment, but
not in all countries.
In addition to the limitations of the traffic sign detection system ÿ
p. 29 and the limitations of ACC, anticipatory speed regulation
has the following limitations inherent to the system:
WARNING
and:
The intelligent technology of pre-speed control cannot
overcome the limits imposed by physical laws and only works
within the limits of the system. Never let the increased comfort
provided by this feature induce you to take any risk that
compromises safety. If used carelessly or inadvertently, it can
cause accidents and serious injuries. The system cannot replace
the driver's attention.
— Advance speed regulation only recognizes traffic signs that
display a speed limitation. The advance regulation of speed
does not take into account, above all, the rules of right of
way or traffic lights.
— Traffic signs showing indirect
mind a speed limitation, e.g. For example, the entrance
signs to towns are only recognized based on navigation data.
Always adapt your speed to the conditions
visibility, weather, road and traffic.
— On roads not included in the navigation data, or inaccurately
included, anticipatory speed regulation is not available.
· Always remain attentive to traffic and always take
into account the surroundings of the vehicle.
· Always be prepared to regulate the speed yourself.
If the traffic sign detection system is not working
properly or the navigation data is not up to date,
— If a speed limitation is reported based on the navigation data
without being detected by the traffic sign detection system,
the posted speed will be adjusted to the last saved speed.
the speed may change unexpectedly and suddenly
or may not adapt to the current traffic situation. In
addition, the speed regulated by the system may
not correspond to your driving style.
— Pre-speed regulation is not available at speeds below 30 km/
h (20 mph). If you drive more slowly, a message to this effect
is shown on the instrument panel display.
· Always be prepared to regulate the speed yourself.
If you are driving without any active guided route,
if you leave the route calculated by the navigation
system, or if the position of the vehicle cannot be
determined correctly because the GPS does not
provide accurate data, the speed may change
unexpectedly and suddenly. or that it does not
adapt to the current traffic situation.

displayed on the instrument cluster display.

In case of regulation due to a speed limitation, the
detected speed will be saved as the new desired speed.
In the event of regulation due to the layout of the road,
the vehicle will accelerate again after leaving behind the
reason for the regulation and the speed that was saved
will be regulated.
