169 04 Comfort and driving pleasure Collision Warning with Auto-brake (option) WARNING The camera has the same limitations as the human eye. In other words, its "vision is impaired" by adverse weather conditions such as heavy snowfall, dense fog, etc. These conditions may reduce the function of systems that depend on the camera or cause these systems to temporarily stop functioning. Never place any objects, decals, etc., on the windshield in front of the camera. This could reduce or block the camera's function, and could cause one or more of the systems that utilize the camera to stop functioning. Strong sunlight, reflections from the road surface, a dirty road surface, or unclear lane marker lines may drastically reduce the camera's capacity to detect the side of a lane or another vehicle. Fault tracing and actions If the message Camera blocked See manual is displayed, this means that the camera is obscured and cannot detect vehicle or road marker lines in front of the vehicle. This, in turn, means that Collision Warning with Auto-brake, Lane Departure Warning, and Driver Alert Control will not have full functionality. The table lists possible causes for this message being displayed, and suitable actions. 170 04 Comfort and driving pleasure Collision Warning with Auto-brake (option) Symbols and messages in the display
