Do I need to replace the safety belt pretensioners?
YourMechanic
Safety belt pretensioners play a large role in keeping you safe in your vehicle. The pretensioners are part of the front seatbelt system, and are responsible for tightening the tension in the seatbelt when an accident occurs. The pretensioners only work one time, and can only be replaced by a professional. After any accident, you should have your safety belt pretensioners replaced.
