04 Comfort and driving pleasure Collision warning with Full Auto-brake and Pedestrian Detection* The camera's limitations The camera is used by Collision Warning with Auto-brake, Driver Alert Control (see page 179), and Lane Departure Warning (see page 182). WARNING Pedestrians • 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. 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, a pedestrian or another vehicle. 04 The system cannot identify all pedestrians • • • The Collision Warning system can only identify and detect a pedestrian who is standing upright. This person can be standing still, walking or running. This means that the system has to be able to identify a person's head, arms, shoulders, legs, the upper and lower parts of the body and a person's pattern of movement when walking or running. If parts of the body are not visible to the camera, the system cannot detect the pedestrian. The following conditions apply: • In order to detect a pedestrian, the system must have a full view of the person's entire `` * Option/accessory, for more information, see Introduction. 175
