Seat belts

Seat belts are the most effective means of restraining the movement of vehicle occupants in the event of an accident. This reduces the risk of vehicle occupants coming into contact with the vehicle interior.

Wearing seat belts

Risk of injury

A seat belt which is not worn correctly, or which has not been engaged in the seat belt buckle correctly, cannot perform its intended protective function. Under certain circumstances this could cause severe or even fatal injuries.

Make sure that all occupants in particular, pregnant women wear their seat belt correctly at all times.

  • The seat belt must pass closely over your body and must not be twisted. You should therefore avoid wearing bulky clothing (e.g. a winter coat). The shoulder belt section must be routed across the middle of your shoulder on no account across your neck or under your arm and pulled tight against your upper body. The lap belt must always pass across your lap as low down as possible, i.e. over your hip joints not across your abdomen. If necessary, tighten the belt strap by pulling it down slightly and retighten in the direction of the inertia reel.

  • Do not route the belt strap across sharp or fragile objects, especially if these are located on or in your clothing, e.g. spectacles, pencils, keys, etc. The seat belt strap could be damaged and tear in an accident and you or other vehicle occupants could be injured.

  • Only one person should use each seat belt at any one time. On no account should children travel sitting on your lap or the lap of another occupant, as it would not be possible to restrain the child in the event of an accident, braking or a sudden change in direction, which could result in severe or even fatal injuries to the child and other occupants.

  • Persons less than 1.50 m tall cannot wear the seat belts correctly. For this reason, secure persons less than 1.50 m tall in specially designed, suitable restraint systems.

  • Children less than 1.50 m tall or under 12 years of age cannot wear the seat belts properly. Therefore, always secure these children in suitable child restraint systems on suitable vehicle seats. You can find more information under "Children in the vehicle" in the "Safety" section of the Owner's Manual. Follow the manufacturer's installation instructions when fitting the child restraint system.

  • Do not secure any objects with a seat belt if the seat belt is also being used by one of the vehicle's occupants.

Risk of injury

The seat belt does not offer the intended level of protection unless the backrest is almost vertical. Under certain circumstances this could cause severe or even fatal injuries.

Before starting a journey, make sure that the seat is properly adjusted and that the backrest is almost vertical.

Risk of injury

A dirty or damaged seat belt or a seat belt that has been subjected to a load in an accident or modified no longer offers the intended level of protection. Under certain circumstances this could cause severe or even fatal injuries.

For this reason, check regularly that the seat belts are not damaged or dirty.

Always have damaged seat belts or seat belts that have been subjected to a load in an accident replaced at a qualified specialist workshop. Choose a qualified specialist workshop which has the necessary specialist knowledge and tools for the work required. Mercedes-Benz recommends that you use a Mercedes-Benz Service Centre for this purpose.

For safety reasons, Mercedes-Benz recommends that you only use seat belts which have been approved by Mercedes-Benz for your vehicle.
