Correct answer
Warn of traffic crossing behind while reversing.
To warn of traffic approaching across the rear while reversing, for example out of a parking bay. Do not assume it always brakes: automatic intervention and operating ranges depend on equipment and model. Read the manual and check the surroundings directly; assistance does not replace the driver.
