Audible Parking Aid Operation
The rear parking aid system uses 3 ultrasonic sensors to calculate the distance to an object around the rear of the vehicle. The rear parking aid sensors detect objects approximately 1, 524 mm (60 in) from the rear of the vehicle, 508 mm (20 in) from the rear side of the vehicle, and 304.8 mm (12 in) above the ground. To detect objects behind the vehicle, the Parking Aid Module (PAM) supplies voltage and ground to the rear ultrasonic sensors while monitoring a signal return circuit from each sensor. The 3 rear sensors share common voltage and ground circuits.
The front parking aid system uses 4 ultrasonic sensors to calculate the distance to an object around the front of the vehicle. The front parking aid sensors detect objects approximately 685.8 mm (27 in) from the front of the vehicle, 457.2 mm (18 in) from the front side of the vehicle, 304.8 mm (12 in) above the ground. To detect objects in front of the vehicle, the Parking Aid Module (PAM) supplies voltage and ground to the front ultrasonic sensors while monitoring a signal return circuit from each sensor. The 4 front sensors share common voltage and ground circuits.
Only objects that reflect a sufficient amount of sound waves are detected by the front or rear parking aid sensors. The surface properties, size and composition of an object can affect the ability of the parking aid system to detect the object. Incorrect sensor alignment or installation, dirt or ice covered sensors, heavy rain and snow can also cause objects not to be detected.
