Seat Belt Tensioners - Seat Exeo ST 2011 Owner's Manual

26 Seat belts
– Take hold of the top guide fitting and slide it up or down so that
the shoulder part of the seat belt is positioned roughly midway
over the shoulder, although it must never rest against the neck
⇒ page 25, fig. 16 A
– After adjusting, pull the belt sharply to check that the catch on
the guide fitting is engaged securely.
Note
It is also possible to adjust the height of the front seats to obtain the best
position for the front seat belts.
Incorrectly fastened seat belts
Incorrectly worn seat belts can cause severe or even mortal
injuries.
Seat belts can provide optimal protection only if the belt web is
properly worn. The seat belts must be fastened exactly in the order
described in this chapter. An incorrect sitting position impairs
substantially the protection a seat belt offers and can lead to severe
or fatal injuries. The risk of severe or fatal injuries is especially
increased when a deploying airbag strikes an occupant who has
assumed an incorrect sitting position. As the driver, you are respon-
sible for all vehicle occupants, especially children. Therefore:
– Never allow anyone to wear the seat belt incorrectly while the
vehicle is moving ⇒

properly and to wear them for the whole journey.

Read and always observe information and warnings concerning the use
of seat belts ⇒ page 21.

Seat belt tensioners

Function of the seat belt tensioner
During a frontal collision, the seat belts on the front seats are
retracted automatically.
The seat belts for the front occupants are equipped with belt tensioners.
Sensors will trigger the belt tensioners during severe head-on, lateral and
rear collisions only if the seat belt is being worn. This retracts and tightens the
seat belts, reducing the forward motion of the occupants.
The seat belt tensioner can be triggered only once.
The seat belt tensioners will not be triggered in the event of a light frontal,
side or rear collision, if the vehicle overturns or in situations where no large
forces act on the front, side or rear of the vehicle.
Note
•
If the seat belt tensioners are triggered, a fine dust is produced. This is
normal and it is not an indication of fire in the vehicle.
•
The relevant safety requirements must be observed when the vehicle or
components of the system are scrapped. Specialised workshops are familiar
