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 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
regulations and driving at a suitable speed.
The speed adaptation made by the system may
not always be suitable, particularly in the follow‐
ing situations:
The road's course not clearly visible
R
Road narrowing
R
Varying maximum permissible speeds in indi‐
R
vidual lanes, for example at toll plazas
Wet road surfaces, snow or ice
R
When towing a trailer
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 calcula‐
R

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
