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 adaptation can be activated in
the multimedia system (
page 297).
/
The following route events are taken into account:
Bends
R
Roundabouts
R
T-junctions
R
Turns and exits
R
Also, the speed is reduced if the turn signal indi-
cator is switched on and one of the following sit-
uations is detected:
Turning off at junctions
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 junctions, roundabouts and
traffic lights, as route-based speed adaptation
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 adaptation is acti-
vated.
Speed adaptation is cancelled in the following
cases:
If the turn signal indicator is switched off
R
before the route event and it is presumed that
the route event is not deemed relevant by the
driver
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.
F243 0059 02
In difficult conditions, the speed selection made
by the system may not always be suitable. This
applies to the following situations, for example:
The road's course is not clearly visible
R
Road narrowing
R
Varying maximum permissible speeds in indi-
R
vidual lanes, for example, at toll stations
Wet road surfaces, snow or ice
R
If transport equipment, for example a trailer or
R
bicycle rack, is attached to the trailer hitch
and the electrical connection has been cor-
rectly established
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:
