Child safety
Locations for i-Size child seats
The i-Size child seats have two latches that engage on the two rings A.
Refer to the "ISOFIX mountings" section.
The i-Size child seats also have:
- either an upper strap which is attached to the ring B (see the "ISOFIX mountings" section).
- or a support leg which sits on the vehicle's floor, compatible with seat approved for i-Size, the role of which is to prevent the child seat from tipping
forwards in the event of a collision.
In accordance with the new European Regulations, this table indicates the options for installing i-Size child seats on seats in the vehicle fitted with
ISOFIX mountings and approved for i-Size.
