The DISTRONIC Distance Assist can aid the driver by automatically maintaining a safe travelling distance to the vehicle ahead at above 20 km/h. A radar sensor in the front bumper provides the necessary data. The system can also detect lane changes or braking manoeuvres by other road users and can react immediately. In an emergency, the active distance assist is able to brake the Sprinter down to a standstill. The vehicle provides both visual and acoustic warnings when the system determines that stronger braking is necessary. If a collision is imminent, the Active Brake Assist could also intervene and attempt to prevent an accident.
