04 Comfort and driving pleasure Collision warning with Auto-brake* NOTE If warnings are given too frequently, the warning distance can be reduced (see page 175). This causes the system to provide later warnings, which decreases the total number of warnings provided. WARNING Fault tracing and actions If the message Windscreen Sensors blocked is displayed, this means that the camera is obscured and cannot detect vehicles 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. 04 • The camera's limitations The camera is used by Collision Warning with Auto-brake, Driver Alert Control (see page 180), and Lane Departure Warning (see page 183). 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, ice or snow covering the road, 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. • NOTE • To help protect the camera in very hot conditions, it may be temporarily switched off for approximately 15 minutes after the engine has been started. Keep the section of the windshield in front of the camera clean and free of ice, snow, or condensation. • • `` * Option/accessory, for more information, see Introduction. 177
