make sure that it is engaged correctly in the
ISOFIX securing loops on both sides. X
Install the ISOFIX child restraint system on
both ISOFIX securing loops :. Comply
with the child restraint system manufactur- er's instructions when installing the ISOFIXchild restraint system.
ISOFIX is a standardised securing system for

approved in accordance with the ECE stand-
ard ECE R44 are permitted for use in the vehi- cle.
Installing a child restraint system on the
front-passenger seat
X Move the seat to its highest and rearmost
position.
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.
X Move the backrest to a 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.
X Move the seat cushion angle to the highest,
most vertical position.
X Move the belt height adjustment to the low-
est position.
Rearward-facing child restraint systems with- out a transponder for automatic child seat
recognition may not be installed on the front-
