Safety and Security Occupant safety Emergency tensioning device (ETD), seat belt force limiter The seat belts for the front and rear outer seats are equipped with emergency tensioning devices and belt force limiters. The ETD is designed to activate in the following cases: in frontal or rear-end impacts exceeding a preset severity level. if the restraint systems are operational and functioning correctly, see 1 indicator lamp ( page 62). i The ETDs for the front seats will only activate if the respective front seat belt is fastened (latch plate properly inserted into buckle). The ETDs for the rear outer seats will activate with or without the respective seat belt fastened. 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 reduce the force exerted by the seat belts on occupants during a crash. Warning! G An emergency tensioning device (ETD) that was activated must be replaced. When scrapping the emergency tensioning device, our safety instructions must be followed. These are available at your authorized Mercedes-Benz Center. 72
