Function of route-based speed adaptation
When Active Distance Assist DISTRONIC is acti‐
vated, the vehicle speed will be adapted accord‐
ingly to the route events ahead. Depending on
the drive program selected, the vehicle negoti‐
ates a route event ahead in a fuel-saving, com‐
fortable 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 restrictions ahead are taken into account.
You can activate and deactivate route-based
speed adaptation in the multimedia system
(
/
page 203).
The following route events are taken into
account:
R
Bends
R
T-junctions, roundabouts and toll stations
R
Turns and exits
R
Traffic jams ahead (only with Live Traffic
Information )
% 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 indi‐
cator to change lanes is switched on and one of
the following 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 adaptation 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.
System limits
Route-based speed adaptation does not take
right of way regulations into account. The driver
is responsible for complying with road traffic
regulations and driving at a suitable speed.
In difficult conditions, the speed selection made
by the system may not always be suitable:
R
unclear roads
R
road narrowing
R
wet road surfaces, snow or ice
R
when towing a trailer
In these situations the driver must intervene
accordingly.
