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 rearward-
facing child restraint.
2 Vehicles with automatic child seat recognition in the front-passenger seat: a child restraint system of the
"Universal" category with a transponder for automatic child seat recognition must be fitted. The PASSENGER
AIRBAG OFF indicator lamp must be lit.
3 Move the front-passenger seat as far back as possible. If you secure a child in a forward-facing child restraint
system on the front-passenger seat, ensure that the shoulder belt strap from the belt outlet on the vehicle
is routed towards the front to the shoulder belt guide on the child restraint system. Set the belt height
adjustment so that the belt strap is routed towards the front along the bottom. Move the front-passenger
seat to the highest position and move the backrest to an almost vertical position. When doing so, ensure
that the complete surface of the child restraint system rests against the backrest of the front-passenger seat
and that the child restraint system does not touch the roof. To do so, you may have to adjust the backrest
down a little. For seats with electrical adjustment, the seat cushion angle must be set to the highest and
most upright position.Children in the vehicle57SafetyZProCarManuals.com
