04 Comfort and driving pleasure Collision warning with Full Auto-brake and Pedestrian Detection* body and the person must be at least 32 in. (80 cm) tall. Fault tracing and actions If the message Windscreen Sensors blocked is displayed, this means that the camera is obscured and cannot detect pedestrians, vehicles or road marker lines in front of the vehicle. This, in turn, means that Collision Warning with Full Auto-brake and Pedestrian Detection, 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. • The system cannot detect a pedestrian carrying a large object. • The camera's capacity to see a pedestrian at dawn or dusk is limited, much as it is for the human eye. • The camera's function is deactivated and 04 will not detect a pedestrian in darkness or in tunnels, even if there is street lighting in the area. WARNING • Collision Warning with Full Auto-brake and Pedestrian Detection is designed to be a supplementary driving aid. It is not, however, intended to replace the driver's attention and judgement. The driver is always responsible for operating the vehicle in a safe manner. The system cannot detect all pedestrians in all situations, such as in darkness/at night and cannot detect partially hidden pedestrians, people who are less than approx. 32 in. (80 cm) tall, or people wearing clothing that obscures the contours of their bodies. • 176 * Option/accessory, for more information, see Introduction.
