Pre-collision assist depends on the detection ability of its camera and sensors. Any obstructions or damage to these areas can limit detection or prevent the system from functioning.   See   Locating the Pre-Collision Assist Sensors
The system is active at speeds above 3 mph (5 km/h)
Note:   Brake support and automatic emergency braking are active up to the maximum speed of the vehicle.
Pedestrian Detection Limitations
Pedestrian detection is active at speeds up to 50 mph (80 km/h).
Pedestrian detection functions optimally when detected hazards are clearly identifiable. System performance may reduce in situations where pedestrians are running, partly obscured, have a complex background, or cannot be distinguished from a group.
Cyclist Detection Limitations
Cyclist detection is active at speeds up to 50 mph (80 km/h).
Cyclist detection functions optimally when detected hazards are clearly identifiable. System performance may reduce in situations where cyclists are fast-moving, partly obscured, have a complex background, or cannot be distinguished from a group.
Intersection Assist
The pre-collision assist system may operate in a scenario where you are turning across an oncoming vehicle's path. Detection of vehicles driving in an oncoming direction is active if your vehicle is driving at speeds up to 19 mph (30 km/h).
