If you brake, deactivate ESP
venes, Active Distance Assist DISTRONIC is
deactivated. The variable limiter is not deacti-
vated.
Function of Active Speed Limit Assist
If a change in the speed limit of 20 km/h or more
is detected and automatic adoption of speed lim-
its is activated, the new speed limit is automati-
cally adopted as the stored speed (
The driven speed is adjusted when the vehicle is
level with the traffic sign at the latest. In the case
of signs indicating entry into an urban area, the
speed is adapted according to the speed permit-
ted within the urban area. The speed limit display
in the driver's display is always updated when the
vehicle is level with the traffic sign.
If you are driving on German motorways and there
is no speed limit, the system uses the speed
stored for a stretch of road with no speed limit as
the set speed. If you do not alter the stored speed
on a stretch of road with no speed limit, the rec-
ommended speed of 130 km/h is adopted.
If Active Distance Assist DISTRONIC has been put
into passive mode by pressing the accelerator
pedal, only speed limits which are higher than the
®
®
or if ESP
inter-
set speed are adopted.
The maximum permissible speed does not take
the road condition and current weather and traffic
conditions into account. Adjust your speed
accordingly, when necessary.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognise
dangers (

System limits
The system limits of Traffic Sign Assist apply to
the detection of traffic signs (
Speed limits below 20 km/h are not automatically
adopted by the system as the stored speed. Tem-
porary speed restrictions (e.g. for a certain time
or due to weather conditions) cannot be properly
detected by the system. The maximum permissi-
ble 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:
at speed limits below 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 a fuel-saving, 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
