Blind Spot Assist monitors the area shown in the figure up to 10 ft (3 m) behind and immediately adjacent to your vehicle.

WARNING  

WARNING Blind Spot Assist monitors certain areas in the 
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.

If the lanes are narrow, vehicles driving in the lane beyond the lane next to your vehicle may be indicated, especially if the vehicles are not driving in the middle of their lane. This may be the case if the vehicles are driving on the inner side of their lane.

Due to the nature of the system:

warnings may be issued in error when driving close to crash barriers or similar solid lane borders.
warnings may be interrupted when driving alongside particularly long vehicles, for example trucks, for a prolonged time.

The two sensors for Blind Spot Assist are integrated into the sides of the rear bumper.

Make sure that the bumper is free from dirt, ice or slush around the sensors. The radar sensors must not be covered, for example by bicycle racks or overhanging cargo. 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, such as an authorized Mercedes- Benz Center. Blind Spot Assist may otherwise not work properly.
