Audible and/or visual rear parking assistance
This system consists of four proximity sensors, located in the rear bumper.

This detects any obstacle (person, vehicle, tree, gate, etc.) behind the vehicle, except obstacles located just below the bumper.
An object, such as a stake, a roadworks cone or any other similar object may be detected at the beginning of the manoeuvre, but may no longer be detected when the vehicle comes close to it.
