Each radar in the car has its own detection zone. The zone is limited by the radar's field of view and range.
Objects in the field of view block what's behind them. The closer something is to the radar, the more it blocks the radar's field of
view.
If a radar is blocked, certain features may become less effective or respond incorrectly.
If the car detects that a radar is blocked, it may disable certain features.
Do not place or mount anything in front of or close to the car's radars. This includes stickers, car body foil and adhesive
tape.
Paintwork damage in front of a radar can affect its performance. Contact an authorised Volvo workshop for repairs if there
is any damage close to the radars.[1]
Make sure that any mounted accessories, extra equipment or externally-stowed cargo don't block the car's radars.
Trailers, bike racks or other towbar-mounted equipment can block the radar, making it and certain features unavailable.
Radars are sensitive to buildups of dirt, ice or snow in front of them. This affects the radio waves and can reduce the radar's
ability to detect objects. Radar obstruction cannot always be identified by the car. In situations where it is detected, the car
communicates this via notifications in the display. However, it is still recommended to regularly inspect the radars and
make sure the areas around them are clean and free of obstructions.
Warning
Clean regularly
Camera, sensor and radar locations on the car must be cleaned on a regular basis and kept free from labels, objects, dirt
and other potential obstructions. Otherwise, car functions may respond incorrectly or become less responsive or
deactivated.
Other conditions and limitations
Other radar sources can cause interference and reduce the effectiveness of your car's radars.

10.2.4. Parking sensor detection and limitations
The ultrasonic parking sensors allow the car to detect objects and their distance from the car. They operate at
relatively close range during slow and tight manoeuvring, such as when parking.
Ultrasonic sensors use sound waves to detect obstacles close to the car. They work by sending out ultrasound pulses that can
bounce back to the sensor when they encounter an object or barrier. This allows the car to identify the distance to obstacles in
the direction of detection.
Information from these sensors is only available at low speeds. They provide distance information when the parking view is
shown in the display.
