Suitability of the seats for attaching a belt-secured child restraint system
If you use a baby car seat of category 0 or 0+ or a rearward-facing child restraint system of
category I on a rear seat, you must adjust the driver's or front-passenger seat so that the seat
does not touch the child restraint system.
If you use a category I, forward-facing child restraint system, you should remove the head
restraint of the respective seat (Y page 122), if possible. The backrest of the child restraint
system must, as far as possible, lie flat against the backrest of the seat.
Always observe the notes in the "Child restraint system" section (Y page 64) and the child
restraint system manufacturer's installation instructions.
When you remove the child restraint system you must replace the head restraints again
immediately (Y page 121). All vehicle occupants must adjust their head restraints correctly
before beginning the journey.
