The seat belt does not offer the intended level of protection if you have not moved the seat backrest to an almost vertical position.
When braking or in the event of an accident, you could slide underneath the seat belt and sustain abdominal or neck injuries, for example.
Persons under 1.50 m tall cannot wear the seat belt correctly without a suitable additional restraint system.
If the seat belt is not worn correctly, it cannot perform its intended protective function. In addition, an incorrectly fastened seat belt can also cause injuries, for example, in the event of an accident or when braking or changing direction suddenly.
If the seat belts are damaged, modified, extremely dirty, bleached or dyed
If the seat belt buckle is damaged or extremely dirty
If the seat belt tensioners, seat belt anchorages or seat belt retractors have been modified
Seat belts may be damaged in an accident, although the damage may not be visible, e.g. due to splinters of glass.
Modified or damaged seat belts may tear or fail, e.g. in an accident.
Modified seat belt tensioners could accidentally trigger or fail to function as intended.
Mercedes-Benz recommends that you use seat belts which have been approved for your vehicle by Mercedes-Benz.
Pyrotechnic seat belt tensioners that have been deployed are no longer operational and are unable to perform their intended protective function.
Mercedes-Benz recommends that you have the vehicle towed to a qualified specialist workshop after an accident.
If an unused seat belt is not fully retracted, it may become trapped in the door or in the seat mechanism.
