Manual Zoom

The manual zoom feature is generated by the rear parking aid camera and has one level of zoom. If the manual zoom feature is on and the vehicle is shifted out of reverse, the manual zoom feature is disabled and must be re-enabled the next time reverse is selected. When the driver turns the zoom on or off at the audio system display, the zoom command is sent through HS-CAN3 to the GWM then over HS-CAN1 to the BCM. The BCM then sends the manual zoom request message to the rear parking aid camera via the LIN circuit and the camera turns the zoom on or off.
