192 Driving and parking
% 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:
Turning off at intersections
R
Driving on slowing-down lanes
R
Driving on 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 cir‐
cles and 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 canceled in the following
cases:
If the turn signal indicator is switched off
R
before the route event.
If the driver depresses the accelerator or
R
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, for example unclear roads,
lane narrowing, wet road surfaces, snow or ice,
or when driving with a trailer, the speed adjust‐
ment made by the system may not always be
suitable. In these situations the driver must
intervene accordingly.
& WARNING Risk of accident in spite of
route-based speed adjustment
Route-based speed adjustment might mal‐
function or be temporarily unavailable in the
following situations:
If the driver does not follow the calcula‐
R
ted route
If map data is not up to date or available
R
In road construction areas
R
In bad weather or road conditions
R
If the accelerator pedal is depressed
R
In the event of electronically displayed
R
speed limitations
Adjust the speed to the traffic situation.
