242 Driving and parking
If the driver has put Active Distance Assist
DISTRONIC into passive mode by pressing the
accelerator pedal, only speed limits that are
higher than the set speed are adopted.
The maximum permissible speed does not take
into account 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 recognize
dangers (
page 224).
/
System limits
The system limits of Traffic Sign Assist apply to
the detection of traffic signs (
page 259).
/
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 maximum permissible speed applying to a
vehicle with a trailer is not detected by the sys-
tem.
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 12 mph (20 km/h)
R
in wet conditions or in fog
R
when towing a trailer
R
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 energy-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
front, vehicles detected ahead and speed restric-
tions ahead are taken into account.
Route-based speed adaptation can be activated in
the multimedia system (
page 243).
/
The following route events are taken into account:
Bends
R
Traffic circles
R
T-intersections
R
Turns and exits
R
Traffic jams ahead (only with Live Traffic )
R
Also, the speed is reduced if the turn signal indi-
cator is switched on and one of the following sit-
uations is detected:
Turning at intersections
R
Driving in slowing-down lanes
R
Driving in lanes adjacent to slowing-down
R
lanes
The driver is responsible for choosing the right
speed and observing other road users. This
applies in particular to intersections, traffic circles
