Seat belts

Protection provided by the seat belt

• Always fasten your seat belt correctly before starting a journey. A seat belt can only provide the best level of protection if it is worn correctly.
• WARNING Risk of injury or death due to incorrectly fastened seat belt incorrectly fastened seat belt
• If the seat belt is not worn correctly, it can‐not 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.
  Always ensure that all vehicle occupants have their seat belts fastened correctly and are sitting properly.

Always observe the instructions about the cor‐rect driver’s seat position and adjusting the seats (/ page 77). In order for the correctly worn seat belt to pro‐vide the intended level of protection, each vehicle occupant must observe the following information:

• The seat belt must not be twisted and must fit tightly and snugly across the body.
• The seat belt must be routed across the center of the shoulder and as low down across the hips as possible.
• The shoulder section of the seat belt should not touch your neck nor be routed under your arm or behind your back.
• Avoid wearing bulky clothing, e.g. a winter coat.
• Push the lap belt down as far as possible across your hips and pull tight with the shoul‐der section of the belt. Never route the lap belt across your abdomen.
  Pregnant women must also take particular care with this.
• Never route the seat belt across sharp, pointed, abrasive or fragile objects.
• Only one person may use each seat belt at any one time. Infants and children must never travel sitting on the lap of a vehicle occupant.
• Never secure objects with a seat belt if the seat belt is being used by one of the vehicle’s occupants. Always observe the instructions for loading the vehicle when securing objects, luggage or loads (/ page 88).
  Also ensure that no objects, e.g. a cushion, are ever placed between a person and the seat.

The co-driver seat belt is equipped with a special seatbelt retractor. Activate or deactivate the special seatbelt retractor of the seat belt (/ page 50). If children are traveling in the vehicle, be sure to observe the instructions and safety notes on “Children in the vehicle” (/ page 47). Reduced seat belt protection

WARNING Risk of injury or death due to incorrect seat position

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 exam‐ple.
Adjust the seat properly before beginning your journey.
Always ensure that the seat backrest is in an almost vertical position and that the shoulder section of your seat belt is routed across the center of your shoul‐der.

WARNING Risk of injury or death when additional restraint systems are not used for persons with a smaller build

Persons under 5 ft (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 can‐not 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.

• Always secure persons under 5 ft (1.50 m) tall in a suitable restraint sys‐tem.

WARNING Risk of injury or death due to damaged or modified seat belts

Seat belts cannot provide protection in the following situations:

• The seat belt is damaged, has been modified, is extremely dirty, bleached or dyed
• The seat belt buckle is damaged or extremely dirty
• Modifications have been made to the Emergency Tensioning Device, seat belt anchorage or seat belt retractor

Seat belts may sustain non-visible damage in an accident, e.g. due to glass splinters. Modified or damaged seat belts could tear or fail in the event of an accident, for example. Modified Emergency Tensioning Devices may be deployed unintentionally or not function as intended.

• Never modify the seat belts, Emergency Tensioning Devices, seat belt ancho‐rages or seat belt retractors.
• Make sure that the seat belts are not damaged, are not worn and are clean.
• Always have the seat belts checked immediately after an accident at a qualified specialist workshop.

Only use seat belts which have been approved for your vehicle by Mercedes-Benz.
Vehicles with AMG Performance seats
The AMG Performance seat is designed for the standard three-point seat belt. If you install a dif‐ferent multipoint seat belt, e.g. sport or racing seat belts, the restraint system cannot provide the intended level of protection.

WARNING Risk of injury or fatal injury due to modified seat belt systems

If you feed seat belts through the opening in the seat backrest, the seat backrest may be damaged or may even break in the event of an accident.

• Only use the standard three-point seat belt.
• Never modify the seat belt system.
