Safety and Security Occupant safety Emergency tensioning device (ETD), seat belt force limiter The seat belts 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 the system deployment threshold if the restraint systems are operational and functioning correctly, see 1 indicator lamp ( page 66) in certain vehicle rollovers if the system determines an additional degree of protection When activated, 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! Roll bar Warning! G G An emergency tensioning device (ETD) that was activated must be replaced. When disposing of the emergency tensioning device, our safety instructions must be followed. These are available at your authorized Mercedes-Benz Center. This vehicle is a two occupant vehicle. The rear storage area is not intended for use by occupants and is not equipped for properly seating or restraining occupants. Thus this area should never be used by any persons. Before operating the roll bar switch make sure that the roll bar's path is clear and no persons are injured by the moving roll bar due to inattention. Raising or lowering of the roll bar could injure someone in it's proximity. For your own safety, we recommend to drive with the roll bar raised if the outside temperature is below +5°F (-15°C). i The ETDs will only activate if the seat belts are fastened (latch plate properly inserted into buckle). Automatic comfort-fit feature seat belt The automatic comfort-fit feature reduces the retracting force of the seat belts when they are in normal use. ! If the outside temperature falls below +5°F (-15°C), the roll bar must be raised manually using the buttons provided to avoid damaging the hydraulics. 81
