Advice
The driver must ensure that passengers use the seat belts correctly and that they
are all fastened before setting off.
Wherever seated in the vehicle, you must
always fasten the seat belt, even for short
journeys.
Do not invert the seat belt buckles, as they
will not fulfil their role properly.
To ensure the proper functioning of the belt
buckles, make sure that there are no foreign
bodies present (e.g. a coin) before fastening.
Before and after use, ensure that the seat belt
is reeled in correctly.
After folding or moving a seat or rear bench
seat, ensure that the seat belt is positioned
and reeled in correctly.
Installation
The lower part of the strap must be
positioned as low as possible over the pelvis.

– be tightened as close to the body as
possible.
– be pulled in front of you with a smooth
movement, ensuring that it is not twisted.
– only be used to secure one person.
