Manual Zoom
The manual zoom feature is controlled by the rear parking aid camera. The feature is only available when the transmission is in reverse. Depending on vehicle equipment, when the driver manually zooms the rear parking aid camera image, the zoom command message is sent from the APIM or FCDIM through the BCM to the rear parking aid camera. The rear parking aid camera then zooms the image.
The manual zoom feature has 1 zoom level that is only active when the vehicle is in REVERSE. If the manual zoom feature is enabled and the vehicle is shifted out of reverse, the manual zoom feature is disabled. The manual zoom feature must be re-enabled the next time the vehicle is shifted into reverse.
