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 changed speed limit is detected and the auto-
matic adoption of speed limits is switched on, this
is automatically adopted as the stored speed
(
page 297). Speed limits below 20 km/h are
/
not accepted.
Adjustment of travel speed is initiated no later
than when the vehicle is level with the traffic sign.
For signs indicating entry into an urban zone, the
speed is adapted according to that permitted
within the built-up area. The speed restriction indi-
cator on the driver display is always refreshed
when the vehicle is level with the traffic sign.
If you are driving on German motorways with 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 recom-
mended speed of 130 km/h is adopted.
If Active Distance Assist DISTRONIC has been put
®
®
or if ESP
inter-
into passive mode by pressing the accelerator
pedal, only speed limits which are higher than the
set speed are adopted.
The maximum permissible speed does not con-
sider the road condition and current weather and
traffic conditions. Adjust your speed accordingly
when necessary.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognise
potential 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 specific time
or due to weather conditions) cannot be unequiv-
ocally detected by the system.
Adjust the speed in these situations.

▌Function of route-based speed adaptation
When Active Distance Assist DISTRONIC is activa-
ted, the vehicle speed will be adapted to the route
events ahead. Depending on the drive program
selected, the vehicle negotiates a route event
ahead in an energy-saving, comfortable or
dynamic manner. When the route event has been
passed, the vehicle accelerates again to the
