The Rear Cross Path function (RCP) is intended to aid you when you back out of a parking spot and a vehicle appears out of nowhere. Using peripheral sensors located on either side of the rear bumper, the RCP system monitors the rear detection zones on both sides of your vehicle.
When an unseen vehicle is approaching and you’re reversing out a parking space, the system will alert you with a visual and an acoustic alarm. If the radio is on, it will also reduce the volume.
Always remember to proceed very slowly and cautiously out of the parking space until the rear end of the vehicle is moderately exposed.
