Manual Zoom
The manual zoom feature is controlled by the video camera. The feature is only available when the transmission selector is in reverse. When the driver manually zooms the rear video camera image, the zoom command message is sent from the APIM through the BCM to the video camera. The video camera then zooms the image to the requested level.
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.
