Update driving assistance system control unit software

Mercedes-Benz AG ("MBAG"), the manufacturer of Mercedes-Benz, has determined that on certain Model Year ("MY") 2021 S-Class (223 platform) vehicles, the software for the driving assistance system control unit may not correspond to the current production specification. This may result in faulty long-range radar based warnings occurring. An authorized Mercedes-Benz dealer will update the driving assistance control unit software.
