Q: What are the checks and actions to be taken for the seat belt system on Mercury Mariner?
A: Look out for any harm or wear and tear on those seat belts, buckles, latch plates and guide loops. Once the key is turned to the Rumor Start position, check whether the seat belt reminder light comes on and a bell rings. When it comes to sudden stops or crashes, the seat belts lock up but remain slack normally. Also, confirm that the retractors return the belt against your chest while driving and rewind the belt all the way when you unlatch the buckle. Replace parts as necessary if any of these checks show problems with your seat belt system.
