Speed limiter with proac-
tive speed adjustment
Introduction
The speed limiter with proactive speed adjust-
ment automatically adapts a maximum speed
that you have saved to the detected speed lim-
its.
The speed limiter with proactive speed adjust-
ment is an additional function of the speed
limiter and uses the infotainment system’s dy-
namic road sign display
and navi-
gation data.
The speed limiter with proactive speed adjust-
ment is available depending on the equipment,
but not in all countries.
WARNING
The smart technology of the speed limiter
with proactive speed adjustment cannot
overcome the limits imposed by the laws of
physics and only works within the limits of
the system. Never allow the greater conven-
ience offered by this function to induce you
to take any risk that compromises safety. Se-
rious accidents and injuries can occur if the
speed limiter with proactive speed adjust-
ment is used carelessly or unintentionally.
The system is not a replacement for driver
awareness.
•
Always adapt your speed to suit visibility,
weather, road and traffic conditions.
•
Always pay attention to traffic and always
keep the vehicle environment in mind.
•
Always be prepared to adjust the speed
yourself. If the traffic sign recognition system
is not working properly or the navigation data
is not updated, the speed may change unex-
pectedly and suddenly or may not be suitable
for the current traffic situation. In addition,
the speed adjusted by the system may not
suit your driving style.
•
Always be prepared to adjust the speed
yourself. If you drive without any active gui-
ded 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 may not adapt to the current
traffic situation.
•
Always use up to date navigation data.
•
Always take into account the maximum
permitted speed. In the case of speed limita-
tions that are not included in the navigation
data, the maximum permitted speed may be
exceeded.
Note
Please also note the information of relevance
to safety on the speed limiter

Limitations of proactive speed ad-
justment
In addition to the limitations of the dynamic
road sign display system
, the
speed limiter with proactive speed adjustment
has the following limitations inherent to the
system:
•
The speed limiter with proactive speed ad-
justment only recognises traffic signs showing
a speed limit.
