Normal Operation

The rear parking aid system is enabled when the vehicle ignition is in RUN and REVERSE (R) 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. A low pitch variable rate warning tone is generated from a parking aid speaker. The parking aid speaker increases the warning tone rate as the vehicle gets closer to an obstacle.

The front parking aid system is enabled when the vehicle ignition is in RUN and DRIVE (D) is selected. The PAM calculates the distance to an object by the use of 4 ultrasonic sensors mounted in the front bumper. The parking aid sensors can detect obstructions in the front of the vehicle. A high pitch variable rate warning tone is generated from a parking aid speaker. The parking aid speaker increases the warning tone rate as the vehicle gets closer to an obstacle.

The attenuation time for the front and rear parking aid sensors is the time required for a sensor to detect the distance to a an object expressed in milliseconds (ms).
