192 Driving systems G Warning Blind Spot Assist may otherwise not work properly. 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. There is no display and no warning. 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 that edge of their lane which 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. Information and warning display Driving and parking : Yellow indicator lamp/red warning lamp If the lanes are narrow, the system may be unable to distinguish the neighboring lane from the one beyond it. For this reason, the system may indicate vehicles in the farther lane, 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 that edge of their lane which is nearest your vehicle. Due to the nature of the system: Rwarnings may be issued unnecessarily when driving close to crash barriers or similar solid lane borders. Rthe warning may be interrupted when traveling next to long vehicles for extended periods. The two sensors for Blind Spot Assist are integrated into the sides of the rear bumper. Make sure that the bumper is free of dirt, ice or slush around the sensors. For example, the radar sensors must not be covered by bicycle racks or overhanging loads. In the event of a severe impact or damage to the bumpers, have the function of the radar sensors checked at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center. If Blind Spot Assist is switched on, indicator lamps : in the exterior mirrors light up yellow up to a speed of 20 mph (30 km/h). At speeds above 20 mph (30 km/h), the indicator lamp goes out and Blind Spot Assist is operational. If a vehicle is detected within the monitoring range of Blind Spot Assist at speeds above 20 mph (30 km/h), warning lamp : on the corresponding side lights up red. This warning is always emitted when a vehicle enters the blind spot monitoring range from behind or from the side. When you overtake a vehicle, the warning only occurs if the difference in speed is less than 7 mph (12 km/h). The yellow indicator lamp goes out if the reverse gear is engaged. In this event, Blind Spot Assist is no longer active. The brightness of the indicator/warning lamps is adjusted automatically according to the ambient light. G Warning Blind Spot Assist is not active at speeds under approximately 20 mph (30 km/h). The indicator lamps in the exterior mirrors are yellow. Vehicles in the monitoring range are then not indicated. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to
