Note
● After certain driving situations, the reversi-
ble belt tensioners may be left permanently
tensioned
. In this case, to loosen the belt, it
1)
must be removed manually while the vehicle
is stationary and then replaced correctly.
● The relevant safety requirements must be
observed if the vehicle or any components
of the system are to be scrapped. Specialised
workshops are aware of these requirements.
Maintenance and disposal of seat
belt tensioners
The belt tensioners are components of the
seat belts that are installed in the seats of your
vehicle. If you work on the belt tensioners or
remove and install parts of the system when
performing other repair work, the seat belt
may be damaged. The consequence may be
that, in the event of an accident, the belt ten-
sioners function incorrectly or may not func-
tion at all.
So that the effectiveness of the seat belt ten-
sioner is not reduced and that removed parts
do not cause any injuries or environmental
pollution, regulations, which are known to the
specialised workshops, must be observed.
Only if fitted with the PreCrash System.

Safety
WARNING
Improper handling and home repairs to seat
belts, automatic retractors and belt tension-
ers may increase the risk of serious or fa-
tal injuries. The tensioners may not activate,
even though they should, or they may acti-
vate unexpectedly.
●
Never repair, adjust, or disassemble and re-
assemble seat belt components or tension-
ers. Always have this work carried out by a
specialist workshop.
●
Seat belts, tensioners and their automatic
retractors cannot be repaired and have to be
replaced.
For the sake of the environment
Airbag modules and belt tensioners may con-
tain perchlorate.
Observe the legal requirements for their dis-
posal.
PreCrash system
How it works
The PreCrash system is an assistance system
that actives a series of measures to protect
the occupants of the vehicles in potentially
risky situations, but which cannot prevent a
collision.
It only works completely if no special driving
profile is selected and if there are no operating
anomalies.
Basic features
Depending on the legal provisions of the coun-
try and the features of the vehicle, in critical
situations (e.g. in certain cases of emergency
braking or loss of control of the vehicle by the
driver) the following functions can be activated
separately or at the same time when the vehi-
cle is travelling faster than approximately 30
km/h (20 mph).
●
Reversible tensioning of front seat belts that
are fastened.
●
Operation of the hazard warning lights.
●
Automatic closing of the windows until they
are just cracked open and, depending on the
equipment, of the sunroof.
●
In the event of overturning, depending on
the equipment, activation of the belt tension-
ers.
Depending on how critical the driving situation
is, the belts are either tightened individually, or
both belts at the same time.

In vehicles with Front Assist
within the limits of the system, information is
assessed on the risk of collision with the ve-
