Definitely not working. Passed several deer on roadside and no alarm. I doubt the XC40 has this functionality as promoted.

Other threads imply that this isn't how this feature works. It doesn't identify deer on the side of the road. It identifies deer ON the road, the ones you are in danger of smacking.

Jeff was correct. It does not detect harmless deer on the side of the road (why should it?) But basically it works like the pedestrian emergency braking system. As soon as the object attempted to cross the path of the car, the car will brake faster than you can react.
