When it comes to safety, our engineers never stop with their research. Thus, in addition to the one-box concept with its intelligent crumple zone design, the A-Class incorporates many important technologies that make driving even safer and help to prevent accidents. Airbags, crash-responsive head restraints, seat belts and emergency locator lighting are all part of the passive safety concept. Intelligent systems such as the Electronic Stability Program (ESP®), the anti-lock braking system (ABS), Brake Assist (BAS) and adaptive brake light help you to master critical driving situations.
