WARNING Risk of injury or death if a
seat belt is unfastened while the vehicle
is in motion
If the seat belt is released while the vehicle is
in motion, the child restraint system is no
longer correctly secured. The child seat
safety feature is deactivated and the seat
belt is drawn in a bit by the inertia reel.
It is therefore not possible to engage the seat
belt again.

Pull over and stop the vehicle safely as
soon as possible, paying attention to
road and traffic conditions.

Activate the child seat safety feature

restraint system.
When enabled, the special seatbelt retractor
ensures that the seat belts of the front
passenger seat and rear seats do not slacken

ped with a special seatbelt retractor:
R
