Steering assistance with braking
Intervention with steering assistance and braking.
Braking intervention assists in situations where steering assistance alone is not suffi-cient. Braking force is automatically adaptedaccording to the situation at the moment thevehicle begins to run off the road. The function is active at speeds between 65-140 km/h (40-87 mph) on roads withclearly visible traffic lane markings/lines. The system uses a camera to monitor the edges of the road and the painted side markerlines. If the vehicle is about to cross the edgeof the road, the function will attempt to steerthe vehicle back onto the road. If this is notsufficient to keep the vehicle on the road, thebrakes will also be applied. However, the function will not provide either
steering assistance or braking if the turn signal is used. The function will also not be activated if it detects that the driver is actively operatingthe vehicle.

for smaller vehicles such as motorcycles
if more than half of your vehicle has moved into the adjacent lane
on roads/lanes with indistinct or no sidelane markings
outside the speed range 60-140 km/h(37-87 mph)
when speed-dependent power steeringwheel resistance is working at reducedpower – e.g. during cooling due to over-heating.
Functionality may also be reduced in other sit-uations, such as: road work
winter driving conditions
narrow roads
poor road surfaces
a very sporty driving style
bad weather with reduced visibility.
In these demanding driving conditions, the function may not be able to properly assist thedriver. In these situations, it is recommendedthat it is turned off.
