Traffic jams ahead (only with Live Traffic Infor-
R
mation )
% 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 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 circles
and traffic lights because 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 acti-
vated.
Speed adaptation 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 regula-
tions and driving at a suitable speed.
The speed adaptation made by the system may
not always be suitable, particularly in the following
situations:
the road's course not clearly visible
R
Road narrowing
R
varying maximum permissible speeds in indi-
R
vidual lanes, forexample at toll stations
wet road surfaces, snow or ice
R
In these situations the driver must intervene
accordingly.

& WARNING Risk of accident in spite of
route-based speed adaptation
Route-based speed adaptation can malfunc-
tion or be temporarily unavailable in the fol-
lowing situations:
If the driver does not follow the calculated
R
route
If map data is not up-to-date or available
R
In the event of roadworks
R
In bad weather or road conditions
R
If the accelerator pedal is depressed
R
In the event of electronically displayed
R
speed limitations
Adapt the speed to the traffic situation.
