Manual Zoom
The manual zoom is only supported by the rear camera.
The manual zoom feature has one level of zoom. If the manual zoom feature is on and the vehicle is shifted out of reverse gear, the manual zoom feature is disabled. The manual zoom feature must be re-enabled the next time reverse gear is selected. When the driver turns the zoom on or off at the audio system display, the command is sent from the APIM via the HS-CAN3 to the GWM. The GWM then sends the message to the IPMB through the HS-CAN2. The IPMB sends the manual zoom request message to the rear parking aid camera via the LIN circuit. The camera then turns the zoom on or off.
