braking in good time. The maximum permissible
speed also depends on factors such as the road
surface and traffic conditions.
System limitations
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 for a vehicle with a
trailer is not detected by the system. In these sit‐
uations you must adjust your speed yourself.

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
In the wet 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
%
The availability of the following function is
country-dependent.
When Distance Assist DISTRONIC is active, the
function adjusts the speed depending on the
route events ahead. Depending on the drive pro‐
gram selected, the vehicle negotiates the 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
ahead, vehicles detected ahead and speed
restrictions ahead are taken into account.
Route-based speed adjustment can by config‐
ured in the multimedia system (
→
page 182).
Route events ahead are:
R
Bends
R
T-junctions, roundabouts and toll stations
R
Turns and exits
%
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 to
change lanes is switched on and one of the fol‐
lowing situations is detected:
R
Turning off at junctions
R
On slowing-down lanes
R
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 junctions, roundabouts
and sets of traffic lights, as route-based speed
adaptation does not brake the vehicle to a stand‐
still.
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 activated.
Speed adjustment is cancelled in the following
cases:
R
If the turn signal indicator is switched off
before the route event.
R
If the driver depresses the accelerator or
brake pedal during the process.
