2010 Mercedes-Benz E-Class E350 4dr Sedan (3.5L 6cyl 7A)
Do not waste your money on this option it does not work.Mercedes new this because they put in their manual a warning about what this option would not do. The buyer does not get a chance to read the manual before buying.It says speeds exceeding your vehicle speed will not be detected. It also say's it will only detect (10) feet off of your rear bumper. I know for a fact it will not pickup 10' sometimes. This thing could get someone killed if they don't read the manual before trying to use the alert. The front head restraints will not go all the way down.Talked to dealer ,they said that is the way it was designed. They are other small items that needs to be corrected
