The seat belts in the vehicle are part of the vehicle safety concept . The vehicle safety concept has the following important functions:
Belt retractor
The seat belts on the front seats and all rear seats are equipped with a belt retractor on the shoulder section of the belt. Full freedom
of movement is ensured when the shoulder belt is pulled slowly or when the vehicle is travelling at normal speeds. However, if the belt
is pulled out quickly or during sudden braking, during travel in mountains or bends and during acceleration, the belt retractor blocks
the seat belt.
Fastened seat belts on the front seats may be tensioned automatically by the proactive occupant protection system in critical
situations, for example during an emergency stop or in the event of oversteering or understeering. Both seat belts are slackened again
if the accident does not happen, or when the critical situation has passed. The proactive occupant protection system is ready to be
triggered again .
Belt tensioner
The seat belts for the passengers in the front seats and the outer rear seats in the second row of seats are equipped with belt
tensioners.
The belt tensioners are activated by sensors and tighten the seat belts during severe frontal, side and rear collisions and also possibly
vehicle rollovers. Any slack in the seat belt is tightened. This can reduce the forward movement of the vehicle occupants and their
movement in the direction of the impact. The belt tensioner works together with the airbag system. If the vehicle rolls over, the belt
tensioner will only be activated if the curtain airbags are triggered.
A fine dust may be produced when the airbags are triggered. This is quite normal and does not mean that there is a fire in the vehicle.
WARNING
The protective function of the belt tensioners permits only one activation of the belt tensioners. The system must be replaced if the
belt tensioners have been triggered.
● Belt tensioners that have been triggered, and any affected system parts, must be replaced immediately with new parts that are
approved by Volkswagen for the vehicle.
● Have repairs and modifications to your vehicle carried out only by a suitably qualified workshop. Suitably qualified workshops have
the necessary tools, diagnostic equipment, repair information and qualified personnel. Volkswagen recommends using an
authorised Volkswagen repairer.
● Never install recycled belt tensioner components or components that have been taken from end-of-life vehicles in your vehicle.
● Never modify any components of the belt tensioners.
Belt pre-tensioning
At the beginning of every journey, the belt is automatically pre-tensioned and the belt slack minimised when the driver or front
passenger seat belt is fastened, depending on the driving time and vehicle speed .
Reversible belt tensioning (proactive occupant protection system)
Reversible belt tensioning may trigger in certain driving situations . Examples include:
—Strong braking.
—Oversteer or understeer.
—Minor collisions.
The reversible belt tensioners may remain continuously tensioned after certain driving situations. In this case, the seat belts
must be manually unfastened when the vehicle is stationary and then fastened correctly again in order to release the belt
tensioning.
Belt tension limiter
The seat belts for the front seat vehicle occupants and on the outer rear seats are equipped with belt tension limiters.
