Child occupant Based on the dummy readings in the frontal and side tests, the X3 scored maximum points for its protection of the 3 year old infant. ISOFIX anchorages are available as an option in the front passenger seat. The option includes deactivation of the passnger frontal airbag. The label warning of the dangers of using a rearward facing restraint in that seating position without first disabling the airbag was not sufficiently clear. The presence of ISOFIX anchorages in the rear outboard seats was not clearly marked.
