Reversible belt tensioners*
The seat belts for the front seats are equipped with electrically operated reversible belt tensioners. The following functions are available when the driver's or passenger's seat belt is buckled:
- Automatic belt tensioner: The seat belts are automatically matched to the occupant's profile after you drive off; this will happen after a certain time or when you reach a certain speed. To deactivate the automatic belt tensioner, select the following on the infotainment system: Function selector button CAR > control button (Car)* Systems > Vehicle settings > Seats > Driver's seat or Passenger's seat > Auto belt tensioner > off.
- The seat belts can be tensioned reversibly in certain situations ►Link.
- The seat belts can be also be tensioned reversibly in light collisions.
Pyrotechnic belt tensioners
The seat belts for the front seats are tensioned automatically in frontal, side and rear-end impacts above a certain degree of severity. This helps to reduce the forward motion of the occupants.
In a less severe accident, or in the event of a rollover, the pyrotechnic belt tensioners are not activated.
WARNING!
- False activation of the belt tensioner is possible.
- Any work on the tensioner system or removal and installation of system components for other repairs must be performed by a qualified workshop.
- The pyrotechnic system can only be activated once. If the pyrotechnic belt tensioners have been activated at any time, the system must be replaced.
Note
- Some smoke may be released when the pyrotechnic belt tensioners are activated. This does not mean there is a fire in the vehicle.
- The relevant safety requirements must be observed when the vehicle or components of the system are scrapped. Your authorised dealer is familiar with these regulations and will be pleased to pass on the information to you.
- If the front passenger's airbag has been deactivated*, the reversible belt tensioner* on the passenger's side will be deactivated as well.
