Notice: The spare tire extends farther away from rear of the vehicle than the trailer hitch shown on rear vision camera display. Your spare tire could hit an object even though there appears to be enough distance on the display between the trailer hitch and objects behind you causing vehicle or property damage. Do not use this system to judge the distance between the spare tire and objects behind you. OnStar® System When the System Does Not Seem To Work Properly The rear vision camera system may not work properly or display a clear image in the following situations: • In the dark. • When the sun or the beam of headlights is shining directly into the camera lens. • If ice, snow, mud, or anything else builds up on the camera lens. Clean the lens, rinse it with water, and wipe it with a soft cloth. • If the back of the vehicle is in an accident, the position and mounting angle of the camera may change or the camera may be affected. Be sure to have the camera and its position and mounting angle checked at your dealer. • Extreme high or low temperatures or extreme temperature changes can affect the image displayed.
