Safety Belt Pretensioners Your vehicle has safety belt pretensioners for the driver and right front passenger. Although you cannot see them, they are part of the safety belt assembly. They help tighten the safety belts during the early stages of a moderate to severe frontal or near frontal crash if the threshold conditions for pretensioner activation are met. Pretensioners work only once. If they activate in a crash, you will need to get new ones, and probably other new parts for your safety belt system. See Replacing Restraint System Parts After a Crash on page 87. Safety Belt Extender If the vehicle's safety belt will fasten around you, you should use it. But if a safety belt is not long enough, your dealer will order you an extender. When you go in to order it, take the heaviest coat you will wear, so the extender will be long enough for you. To help avoid personal injury, do not let someone else use it, and use it only for the seat it is made to fit. The extender has been designed for adults. Never use it for securing child seats. To wear it, just attach it to the regular safety belt. For more information see the instruction sheet that comes with the extender. 42
