G WARNING
If you secure ac hild in af orward-facin gc hild
restraint system on the front-passenger seat
and you position the front-passenger seat too
close to the dashboard, in the event of an

fatal injury. Always move the front-passenger seat as far
back as possible and fully retract the seat
cushion length. Always make sure that the
shoulder belt strap is correctly routed from
the vehicle belt sash guide to the shoulder
belt guide on the child restraint system. The
shoulder belt strap must be routed forwards
and downwards from the vehicle belt sash
guide. If necessary, adjust the vehicle belt
sash guide and the front-passenger seat
accordingly. Always observe the child
restraint system manufacturer's installation
instructions.
If OCS determines that: R
The front-passenger seat is unoccupied, the
PASSENGER AIR BA GO FF indicator lamp
lights up after the system self-test and
remains lit. This indicates that the front-
passenger fron ta ir bag is deactivated. R
The front-passenger seat is occupied by a
child of up to twelve months old, in as tandard
child restraint system, the PASSENGER AIR
BA GO FF indicator lamp lights up after the
system self-test and remains lit. This indi-
cates that the front-passenger fron ta ir bag is
deactivated.
But even in the case of at welve-month-old
child, in as tandard child restraint system, the
PASSENGER AIR BA GO FF indicator lamp can
go out after the system self-test. This indi-
cates that the front-passenger fron ta ir bag is
activated. The result of the classification is
dependen to n, among other factors, the child
restraint system and the child's stature. It is
recommended that you install the child
restraint system on as uitable rear seat.R

person of smaller stature (e.g. at eenager or
