Another example of the technology transfer from the luxury to the compact class are the MULTIBEAM LED headlamps. These allow extremely quick and precise, electronically controlled adjustment of the headlamps to suit the current traffic situation. 18 individually actuated LEDs are housed in each headlamp.
The new A-Class is equipped with the latest driving assistance systems, which give the driver cooperative support. This means that it has the highest level of active safety in its segment, with functions adopted from the S‑Class. For the first time, the A-Class is able to drive semi-autonomously in certain driving situations. Active Distance Assist DISTRONIC and Active Steering Assist now support the driver even more conveniently in keeping a safe distance and steering, and the vehicle speed is now also automatically adjusted on bends, at road junctions and on roundabouts.
The Driving Assistance package includes the following systems: Active Distance Control DISTRONIC with route-based speed adjustment; Active Steering Assist with Active Lane Change Assist and Active Emergency Stop Assist; Active Speed Limit Assist; Active Brake Assist with cross-traffic function; Evasive Steering Assist; Active Blind Spot Assist; PRE-SAFE® PLUS. PRE-SAFE®PLUS can recognise an imminent rear-end collision. If the danger of a collision persists, the system can lock the brakes of the stationary vehicle before a rear-end collision to prevent it from being shunted forward by the impact. This can minimise the risk of injury by reducing the forward jolt caused by the impact.
Further PRE-SAFE® functions are included in the Driving Assistance package, but are also separately available in the PRE-SAFE® system. The PRE‑SAFE® system makes use of the time before an impending accident. Numerous measures can reduce the loads acting on the occupants. These also include the innovative PRE-SAFE® Sound system. This prepares the human hearing for the expected noise of an impact when there is a risk of a collision. When the danger of a collision is detected, the system causes the onboard sound system to emit a short rushing sound, which can activate a tiny muscle in the human ear. This contracts as a reflex when loud noises occur, thus protecting the hearing.
