mation about suitable positioning of the child restraint system in this Owner's Manua las
wellast he child restraint system manufac-
turer's installation instructions. G
WARNING
If you secure achild in aforward-facing child
restraint system on the front-passenge rseat
and you position the front-passenge rseat too
close to the dashboard, in the event of an
accident, the child could:
R come into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
R be struck by the airbag if the PASSENGER
AIR BAG OFF indicator lamp is off
This poses an increased risk of injury or even fatal injury.
Move the front-passenge rseat as far back as
possible.A lways make sure that the shoulder
belts trap is correctly routed from the vehicle
belts ash guide to the shoulderb eltg uide on
the child restraint system. The shoulderb elt
strap must be routed forwards and down-
wards from the belts ash guide. If necessary,
adjust the belts ash guide and the front-
passenger seat accordingly .Always observe
the information about suitable positioning of
the child restraint system in this Owner's
Manual as wellast he child restraint system
manufacturer's installation instructions.
i Ensure that yourv

The system carries out aself-diagnosis.
The PASSENGER AIR BAG OFF indicator lamp
must light up for approximately six seconds.
If, after the system self-test, the
PASSENGER AIR BAG OFF indicator lamp:
R lights up ,the front-passenger fronta irbag is
disabled. It will then not be deployed in the
event of an accident.
R is not lit ,the sensor system did not detect a
child restraint system with transponder for
automatic child seat recognition. If, in the
case of an accident ,all deployment criteria
are met, the front-passenger fronta irbag is
deployed. Childr

If it is absolutely necessary to fit
arearward-
facing child restraint system to the co-driver's
seat, you must always make sure that the co-
driver's front airbag is deactivated. The co-driv-
er's front airbag is only disabled if the
PASSENGER AIR BAG OFF indicator lamp is lit
continuously (Y page 32).
Alwayso bserve the information abouts uitable
positioning of the child restraint system
(Y page 46) as well as the child restraint sys-
tem manufacturer's installation and operating
instructions.
Forward-facingc hildr estraint system If it is absolutely necessary to secure
achild in a
forward-facing child restraint system on the co- driver's seat, you must always move the co-driv-
er's seat as far back as possible. The base of the child restraint system must lie fullyont he co-driver's seat cushion. The backrest of the child
restraint system must lie as flat against the co-
driver's seat backrest as possible.T
he child
restraint system may not touch the roof or be
put under strain by the head restraint .Adjust the
angle of the seat backrest and the head restraint position accordingly. 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 shoul-
der belt strap must be routed forwards and
downwards from the vehicle belt sash guide. If
necessary, adjust the co-driver' sseat accord-
ingly.

X Move the backrest to an almost vertical posi-
tion.
The entire base of the child restraint system
must always rest on the seat cushion of the
front-passenger seat. The backrest of a
forward-facin gchild restraint system must, as
far as possible, rest flat against the backrest
of the front-passenger seat. The child
restraint system must not touch the roof or be
put under strain by the head restraint .Adjust

Suitability of the seats for attaching belt-secured child restraint systems If you use
ababy car seat of category 0or0+orarearward-facing child restraint system of category
Ionar ear seat, you must adjust the driver's or front-passenger seat so that the seat does not touch
the child restraint system.
If you use acategory I, forward-facing child restraint system, you shouldr emove the head restraint
from the respective seat, if possible (Y page 70). The backrest of the child restraint system must,
as far as possible, lie flat against the backrest of the seat.
Make sure that the child's feet do not touch the front seat. If necessary ,move the front seat forward
slightly.
For certain child restraint systems in weight categories II or III, this can mean that the area of use
is restricted. The maximum size setting of the child restraint system may not be possible due to
possible contact with the roof.
Alwayso bserve the notes in the "Child restraint system" section (Y page 40) and the child restraint
system manufacturer's installation instructions.
When you remove the child restraint system, you must replace the head restraints again immedi-
ately (Y page 70). All vehicle occupants must adjust their head restraints correctly before begin-
ning the journey.
