Belt warning for the driver and front
passenger
The ü seat belt warning lamp in the instru-
ment cluster is a reminder for all occupants to
fasten their seat belts. It may light up contin-
uously or flash. In addition, a warning tone
may sound.
The ü seat belt warning lamp goes out and
the warning tone ceases when the driver and
the front passenger have fastened their seat
belt.
Only for certain countries: the ü seat belt
warning lamp lights up for six seconds after
every engine start. This happens regardless of
whether the driver's and front-passenger seat
belts have already been fastened. It then goes
out if the driver and the front passenger have
fastened their seat belts.

WARNING
Pyrotechnic seat belt tensioners that have
been deployed are no longer operational and
are unable to perform their intended protec-
tive function. This poses an increased risk of
injury or even fatal injury.
Therefore, have pyrotechnic belt tensioners
which have been triggered immediately
replaced at a qualified specialist workshop.
! If the co-driver's seat is not occupied, do
not engage the seat belt tongue in the
buckle on the co-driver's seat. Otherwise,
the belt tensioner could be triggered in the
event of an accident and would have to be
replaced.
i
Vehicles with PRE-SAFE
motor is used by PRE-SAFE
tightening of the seat belt in hazardous sit-
uations. This procedure is reversible.
The seat belts are fitted with belt tensioners.
The belt tensioners tighten the seat belts in an
accident, pulling them close against the body.
Belt tensioners do not correct incorrect seat
positions or incorrectly fastened seat belts.
Belt tensioners do not pull vehicle occupants
back towards the backrest.
The belt tensioners can only be activated
when:
the ignition is switched on
R
the restraint systems are operational; see "
R
SRS warning lamp" (
the belt tongue is engaged in the buckle on
R
each of the three-point seat belts
The belt tensioners are triggered depending
on the accident type and severity:
in the event of a head-on or rear-end colli-
R
sion if the vehicle decelerates or acceler-
ates rapidly in a longitudinal direction dur-
ing the initial stages of the impact
in the event of a side impact if the vehicle
R
decelerates or accelerates rapidly in a lat-
eral direction on the side opposite to the
impact
in certain situations where the vehicle over-
R
turns and the system determines that it can
provide additional protection
If the airbags are deployed, you will hear a
bang, and a small amount of powder may also
be released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard and does not indicate that there
is a fire in the vehicle. The powder may cause
short-term breathing difficulties to persons
suffering from asthma or other pulmonary
conditions. In order to prevent potential
breathing difficulties, you should leave the
vehicle as soon as it is safe to do so. You can
also open the window to allow fresh air to
