Ambient lighting conditions

The camera automatically monitors the ambient lighting conditions behind the vehicle and constantly adjusts sensitivity to light. This may cause the brightness and quality of the image on the screen to vary slightly. Sensitivity to light is increased in dark conditions or in bad weather, which may affect image quality.
If the image on the screen seems too dark, brightness can be increased with the thumb wheel on the lighting panel.
NOTE
In order to function properly, the camera
lens should always be kept clean. This is
particularly important in bad weather. Keep
the lens free of dirt, ice or snow.
