Diagnostic Aids

A poor video image can be caused by ice, snow, and mud buildup on the lens of the rear view camera. Also, extreme lighting conditions can affect performance, such as operating in the dark or with bright sunlight shining on the camera. Extreme high or low temperatures can also affect the image quality. For normal operating characteristics of the rear vision camera system, refer to the Navigation System section of the owners manual.
