Your vehicle has safety belt pretensioners. You will find them on the retractor portion of the safety belts for the driver and right front passenger. They help the safety belts reduce a person's forward movement in a moderate to severe crash in which the front of the vehicle hits something.

Pretensioners work only once. If they activate in a crash, you will need to get new pretensioners and may need other new parts for your safety belt system. See Replacing Restraint System Parts After a Crash for more information.
