belt routing).
3. Let go of the shoulder belt guide.
4. Pull sharply on the seat belt to check whether the shoulder belt guide is engaged securely.
WARNING
Never adjust the seat belt height when the vehicle is in motion.
Belt retractor, belt tensioner, belt tension limiter
The seat belts in the vehicle are part of the vehicle safety concept (→ Standard airbag system) and include the
following important functions:
Automatic belt retractor
The seat belts on the front seats and on the rear seats(depending on equipment)are fitted with a belt retractor on
the shoulder section of belt. Full freedom of movement is made possible 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 automatic belt retractor is locked.
Belt tensioners
The seat belts on the front seats are fitted with belt tensioners(depending on equipment).
The belt tensioners are activated by sensors during severe frontal, side and rear collisions. They tighten the seat belts
against the direction in which they are pulled. A loose seat belt is retracted and kept taught, which can reduce the
forward motion of the vehicle occupants and their motion in the direction of impact. Depending on the equipment,
the belt tensioner works together with the airbag system.
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 for the vehicle.
● Have repairs and modifications to your vehicle carried out only by a suitably qualified workshop. Qualified
workshops have the necessary tools, diagnostic equipment, repair information and trained personnel.
● 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.
Reversible belt tensioning (proactive occupant protection system)
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 if the accident does not happen, or when the critical situation has passed. The proactive
occupant protection system is ready to be triggered again.
In certain situations, you can reverse the tensioning process for seat belts. Examples include:
—Strong braking.
—Oversteer or understeer.
—Minor collisions.
