Safety and Security Occupant safety In an impact, emergency tensioning devices remove slack from the belts in such a way that the seat belts fit more snugly against the body. Belt force limiters, when activated, are employed to help reduce the peak force exerted by the seat belts on occupants during a crash. Warning! Active head restraints The active head restraints are intended to offer the driver and front passenger increased protection from whiplash type injuries. In the event of a rear-end collision, the active head restraints on the driver's and front passenger's seats are designed to move forward in the direction of travel, providing the head with increased support earlier on in the collision sequence. The active head restraints move forward whether the seat is occupied or not. Warning! Do not attach any objects (e.g. hangers) to the head restraints posts. Otherwise, the active head restraints may not be able to function properly or offer the intended degree of protection in the event of an accident. G Warning! G A pyrotechnic Emergency Tensioning Device (ETD) that was activated must be replaced. When disposing of the pyrotechnic emergency tensioning device, our safety instructions must be followed. These are available at your authorized Mercedes-Benz Light Truck Center. For your protection, drive only with properly positioned head restraints. Adjust head restraint so that it is as close to the head as possible and the center of the head restraint supports the back of the head at eye level. This will reduce the potential for injury to the head and neck in the event of an accident or similar situation. G Only use seat or head restraint covers which have been tested and approved by Mercedes-Benz for your vehicle model. Using other seat or head restraint covers may interfere with or prevent the activation of the active head restraint. Contact an authorized Mercedes-Benz Light Truck Center for availability. 86
