For enhanced safety, the front and rear seat shoulder belts of the Mercedes AMG C-Class Sedan have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Cadillac CT6-V doesn’t offer pretensioners for the rear seat belts.
