Braking intervention assists in situations where steering assistance alone is not sufficient. Braking force is automatically adapted according to the situation at the moment the vehicle begins to run off the road.
The function is active at speeds between 65-140 km/h (40-87 mph) on roads with clearly visible traffic lane markings/lines.
The vehicle's camera unit monitors the edges of the road and the painted side marker lines. If the vehicle is about to cross the edge of the road, the function will attempt to steer the vehicle back onto the road. If this is not sufficient to keep the vehicle on the road, the brakes will also be applied.
However, the function will not provide either steering assistance or braking if a direction indicator is used. The function will also not be activated if it detects that the driver is actively operating the vehicle.
When the function is intervening, a message is displayed in the instrument panel.
