If the left and right seat backrests are not
engaged and locked in place, this will be shown
on the multifunction display on the instrument
cluster.
If the center seat backrest is not engaged and
locked in place, the red lock verification indica‐
tor will be visible.
When installing a belt-secured child
restraint system, observe the following:
O Always comply with the manufacturer's
installation and operating instructions for
the child restraint system used.
O When using a weight category 0/0+
baby car seat and a weight category I
rearward-facing child restraint system
on a rear seat: adjust the front seat so that
the seat does not touch the child restraint
system.
O The backrest of the forward-facing child
restraint system must, as far as possible, be
resting on the seat backrest of the rear
seat.
O If the head restraint of the child seat cannot
be fully extended when it is installed in the
vehicle, this will result in restrictions on the
maximum size setting for child restraint sys‐
tems in weight category II or III.
Contact with the roof when the head
restraint is fully extended and locked in
place will not result in any restrictions on
use.
O The child restraint system must not be put
under strain between the roof and the seat
cushion and/or be installed facing the
wrong direction. Where possible, adjust the
seat cushion inclination accordingly.
O The child restraint system must not be put
under strain by the head restraint. Adjust
the head restraints as appropriate.
O Make sure that the child's feet do not touch
the front seat. If necessary, move the front
seat slightly forwards.
The seat belts on the following seats are equip‐
ped with a special seat belt retractor:
Front passenger seat
R
Rear seats
R
Occupant safety
When enabled, the special seat belt retractor
ensures that the seat belts of the front
passenger seat and rear seats do not slacken
once the child restraint system is secured
( page 56).
/
Install the child restraint system.
#
The entire base of the child restraint system
must always rest on the sitting surface of the
rear seat.
Always make sure that the shoulder belt
#
strap is correctly routed from the seat belt
outlet of the vehicle to the shoulder belt
guide on the child restraint system.
The shoulder belt strap must be routed for‐
wards and downwards from the seat belt out‐
let.
