When the front windshield where the front view camera is located is covered with foreign material, such as snow or rain, it can reduce the detecting performance and temporarily limit or disable Intelligent Speed Limit Assist. If this occurs, the ‘Speed limit system disabled. Camera obscured’ warning message appears on the cluster.
