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