Driving systems vehicle's speed, braking in good time, and steering correctly. Always adapt your driving style to suit the prevailing road and weather conditions. 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. 321 G Warning i USA only: This device has been approved by the FCC as a "Vehicular Radar System". The radar sensor is intended for use in an automotive radar system only. Removing, tampering with, or altering the device will void any warranties, and is not permitted by the FCC. Do not tamper with, alter, or use in any non-approved way. Any unauthorized modification to this device could void the user's authority to operate the equipment. For Active Blind Spot Assist to assist you when driving, the radar sensor system must be activated (Y page 342) and operational. Monitoring range Active Blind Spot Assist monitors the area up to 10 ft (3 m) behind your vehicle and directly next to your vehicle as shown in the diagram. For this purpose, Active Blind Spot Assist uses sensors in the rear bumper. Active Blind Spot Assist monitors certain areas in the immediate vicinity of your vehicle. Vehicles that approach and drive past at high speeds are not detected. No visual nor audible warnings are emitted and the system does not brake the vehicle to correct your course. If the lanes are very wide, it may not be possible to monitor the complete width of the neighboring lane. For this reason, vehicles in the next lane may not be detected, especially if they are driving in a staggered formation. This may be the case if vehicles are driving at the edge of their lane that is furthest away from your vehicle. 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. If the lanes are narrow, the system may be unable to distinguish the neighboring lane from the one beyond it. For this reason, vehicles in the farther lane may be indicated, especially if the vehicles are driving in a staggered formation in different lanes. In particular, this may be the case if the vehicles are driving at the edge of their lane nearest your vehicle. Due to the nature of the system, warnings may be issued in error when driving close to crash barriers or similar solid lane borders. Two Active Blind Spot Assist sensors are integrated into the front and rear bumpers respectively. An additional sensor is located behind the cover in the radiator grill. Make sure that the bumpers are free from dirt, ice, or slush around the sensors. The rear radar sensors must not be covered, for example by cycle racks or overhanging loads. Following a severe impact or in the event of damage to the bumpers, have the function of the radar sensors checked at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center. Active Blind Spot Assist may otherwise fail to work correctly. Z Driving and parking
