Do the rear parking sensors only beep when they detect objects directly behind the car or should they also beep when approaching objects slightly to the rear sides?

I back into a fairly narrow garage which means having to park very close to a side wall (on the passenger side), yet I never hear any beeps even if I'm about to scrape that side wall.

Is this normal or are my parking sensors not working correctly?

Previous cars I owned would give off warning beeps in those situations.

I鈥檓 thinking that the rear proximity alert sensors are focused pretty narrowly.
When I back into a tight parking space they do not alarm until I get fairly close to the post behind my space. Don鈥檛 notice the nearby cars at all.

oh, i forgot the newer crosstreks had parking sensors. I think with the way they're integrated, you won't really get great readings off the sides of the bumper.

The parking sensors only work for whatever is facing behind the Crosstrek. As for if something walks by, rear cross-traffic alert would beep at you to warn that there's something coming from the sides.

If the car detects that the object moving from either side approaches the vehicle too closely it will auto brake.

To my experience the parking sensors are narrowly focused. I've had mine go off, and even had the car brake, if I back out of the garage too quickly (there's a hedge directly across from garage door). If I am pulled in close to the wall of the garage, the cross-traffic alert will sometimes complain about the little side wall on the passenger side when I'm backing out.

I've been happy with the range and sensitivity of the cross-traffic alert. Here in the Atlanta suburbs people tend to drive in parking lots like it's the expressway.
