Driving and parking General information Driving Assistance package i The Driving Assistance package is only available on vehicles with HYBRID. The Driving Assistance package consists of DISTRONIC PLUS (Y page 325), Blind Spot Assist (Y page 352) and Lane Keeping Assist (Y page 354). Blind Spot Assist Important safety guidelines Blind Spot Assist uses a radar sensor system to monitor the areas on both sides of your vehicle. Blind Spot Assist provides assistance at speeds higher than 20 mph (30 km/h). A warning display in the exterior mirrors draws your attention to vehicles in the monitored area. If you then indicate a turn towards that side before changing lanes, you will also receive visual and audible collision warnings. G Warning Blind Spot Assist is only an aid designed to assist driving. It may fail to detect some vehicles and is no substitute for attentive driving. Blind Spot Assist cannot detect road and traffic conditions. It may fail to detect narrow vehicles, such as motorcycles or bicycles, or may only detect them too late. Monitoring may be affected by dirty sensors, strong spray or poor visibility caused by snow, rain or mist, for example. In this case, vehicles are detected late or not at all. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others. i USA only:
