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 following function is country-dependent
and only available in conjunction with the
Driving Assistance Package.
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 in
front, vehicles detected ahead and speed restric‐
tions ahead are taken into account.
Route-based speed adjustment can be config‐
ured in the multimedia system (
/
page 213).
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
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 junctions, roundabouts
and traffic lights, as route-based speed adapta‐
tion 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 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.
