System limits
The system limits of Traffic Sign Assist apply to
the detection of traffic signs (
/
page 240).
Speed limits below 12 mph (20 km/h) are not
automatically adopted by the system as the stored
speed. Temporary speed restrictions (e.g. for a
certain time or due to weather conditions) cannot
be properly detected by the system. The maxi-
mum permissible speed applying to a vehicle with
a trailer is not detected by the system.
Adjust the speed in these situations.

WARNING Risk of accident due to Active
Speed Limit Assist adapting the vehicle's
speed
The speed adopted by Active Speed Limit
Assist may be too high or incorrect in some
individual cases, such as:
R
at speed limits below 12 mph (20 km/h)
R
in wet conditions or in fog
R
when towing a trailer
#
Ensure that the driven speed complies
with traffic regulations.
#
Adjust the driving speed to suit current
traffic and weather conditions.
Function of route-based speed adaptation
When Active Distance Assist DISTRONIC is activa-
ted, the vehicle speed will be adapted accordingly
to the route events ahead. Depending on the drive
program selected, the vehicle negotiates a route
event ahead in an economical, comfortable or
dynamic manner. When the route event has been
passed, the vehicle accelerates again to the
stored speed. The set distance to the vehicle in
front, vehicles detected ahead and speed restric-
tions ahead are taken into account.
You can activate and deactivate route-based
speed adaptation in the multimedia system
(
/
page 228).
The following route events are taken into account:
R
Bends
R
T-intersections, traffic circles and toll stations
R
Turns and exits
R
Traffic jams ahead (only with Live Traffic Infor-
mation )
%
When the toll station is reached, Active Dis-
tance Assist DISTRONIC adopts the speed as
the stored speed.
Also, the speed is reduced if the turn signal indi-
cator to change lanes is switched on and one of
the following situations is detected:
R
Turning at intersections
R
Driving on slowing-down lanes
R
Driving on lanes adjacent to slowing-down
lanes
The driver is responsible for choosing the right
speed and observing other road users. This
applies in particular to intersections, traffic circles
and traffic lights, as route-based speed adaptation
does not brake the vehicle to a standstill.
When route guidance is active, the first speed
adjustment is carried out automatically. If the turn
signal indicator is switched on, the selected route
is confirmed and further speed adjustment is acti-
vated.
