### Rear Vision Camera System Operation

The rear vision camera system consists of a video camera located at the rear of the vehicle and the navigation radio display.

When the transmission is placed into REVERSE, a 12 V signal is sent to the rear vision camera by the body control module (BCM). This signal indicates to the camera that the vehicle is in reverse and image display is requested. The rear vision camera receives ignition voltage and a constant ground to power the camera. Video signal + and video signal - circuits carry the video image from the rear vision camera to the navigation radio. Additionally, the video signal circuits are shielded to prevent any interference which may lead to a loss of video signal resolution and a degraded video image. The shield is provided a ground path by the rear vision camera.

The following conditions may cause a degraded rear vision camera image:

• | Ice, snow, or mud has built up on the rear vision camera

• | Dark conditions

• | Extreme light conditions, such as glare from the sun or the headlights of another vehicle

• | Damage to the rear of the vehicle

• | Extreme high temperatures or extreme temperature changes
