Detection of obstacles with assistance at risk of collision
The function can detect pedestrians, cyclists or vehicles that are stationary or moving in the same direction as the car and are ahead. The function can also detect pedestrians or cyclists that are crossing the road in front of the car.
Warning
Vehicles
In order for the function to be able to detect a vehicle in the dark, the vehicle's front and rear lights must be working and clearly illuminated.
Cyclists

Good performance requires that the camera and radar units that detect a cyclist must receive the clearest possible information about the body and bicycle outline, requiring the ability to identify the bicycle, head, arms, shoulders, legs, upper and lower body plus a normal human pattern of movement.
If large parts of the cyclist's body or bicycle are not visible to the function's camera then the system cannot detect a cyclist.
For the function to be able to detect a cyclist, he/she must be an adult and riding a bicycle designed for adults.
Warning
- partially obscured cyclists.
- cyclists if the background contrast for the cyclists is poor.
- cyclists wearing clothing that obscures the body outline.
- bicycles loaded with large objects.
Pedestrians

Good performance requires that the camera and radar units that detect a pedestrian must receive the clearest possible information about the body outline, requiring the ability to identify the head, arms, shoulders, legs, upper and lower body plus a normal human pattern of movement.
In order that it shall be possible to detect a pedestrian there must be a contrast with the background and this will be affected by such things as clothes, the background and the weather. With poor contrast the pedestrian may either be detected late or not at all, which may mean that warnings and braking are late or omitted.
The function can also detect pedestrians in the dark if they are illuminated by the car's headlamps.
Warning
- partially obscured pedestrians, people in clothing that hides their body contour or pedestrians shorter than 80 cm (32 tum).
- pedestrians if the background contrast for the pedestrians is poor.
- pedestrians who are carrying larger objects.
