Safety

If you use a baby car seat in Group 0 or 0+ or a rearward-facing child restraint system in Group 1 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 Group 1, forward-facing child restraint system, you should remove the head restraint

from the respective seat, if possible ( Y page 106). The backrest of the child restraint system must,

as far as possible, lie flat against the backrest of the seat.

Make sure that the child's feet do not touch the front seat. If necessary, move the front seat forwards

slightly ( Y page 105).

For certain child restraint systems in weight groups 2 or 3, this can mean that the area of use is

restricted. The maximum size setting of the child restraint system may not be possible due to the

risk of contact with the roof.

Always observe the notes in the "Child restraint system" section ( Y page 60) and the child restraint

system manufacturer's installation instructions.

When you remove the child restraint system, you must replace the head restraints again immedi-

ately ( Y page 106). All vehicle occupants must adjust their head restraints correctly before begin-

ning a journey.

Suitability of the seats for attaching an ISOFIX child restraint system

If you use a baby car seat in Group 0 or 0+ or a rearward-facing child restraint system in Group 1 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 Group 1, forward-facing child restraint system, you should remove the head restraint

from the respective seat, if possible ( Y page 106). 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 60) and the child restraint

system manufacturer's installation instructions.

When you remove the child restraint system, you must replace the head restraints again immedi-

Make sure that the child's feet do not touch the front seat. If necessary, move the front seat forwards

slightly ( Y page 105).

For certain child restraint systems in weight groups 2 or 3, this can mean that the area of use is

restricted. The maximum size setting of the child restraint system may not be possible due to the
