The parking aid system is enabled when the ignition switch is in the RUN position and the REVERSE (R) gear is selected. The Parking Aid Module (PAM) calculates the distance to an object by the use of 4 ultrasonic sensors mounted in the rear bumper. The parking aid sensors can detect obstructions in the path behind the vehicle. The attenuation time for the rear parking aid sensors is the time required for a sensor to detect the distance to an object expressed in milliseconds (ms).
