What Is Pre-Collision Assist?

Pre-Collision Assist is a feature that is part of Ford's driver assistance technology. Your vehicle can alert you to a potential collision with a vehicle, cyclist or pedestrian in front of you and now, while turning at intersections. This feature scans the road ahead and can alert you to a potential collision. If you don’t take corrective action, the brakes can apply automatically. 

Note: Driver-assist features are supplemental and do not replace the driver’s attention, judgment and need to control the vehicle. May not operate at certain speeds, or in certain driving, road or weather conditions.
