Important safety notes G
WARNING
To reduce the risk of serious or even fatal
injury to the child in the event of asudden
change in direction, braking or an accident:
R children less than 1.50 mtall and under
twelve years of age must always be secured
in special child restraint systems on asuit-
able vehicle seat. This is necessary
because the seat belts are not designed for
children.
R Do not drive with achild secured in arear-
ward-facing child restraint system on the
front-passenger seat. Exception: if the vehi-
cle is equipped with automatic child seat
recognition on the front-passenger seat
and the child is secured in achild restraint
system with transponders for automatic
chil dseat recognition
R if you secur eaforward-facing child
restraint system to the front-passenger
seat, you must mov ethe front-passenger
seat as fa rback as possible.
R children must never travel sitting on the lap
of another occupant. Due to the forces
which occur in the event of asudden
change of direction, heavy braking or an
accident, it would not be possible to
restrain the child. The child could be thrown
against parts of the vehicle interior and be
seriously or even fatally injured. 50

NING
If the front-passenge rairbag is not disabled:
R ac hild secured in achild rest raint system
on the front-passenger seat could be seri-
ously and even fatally injured by the front-
passenger airbag deploying. This is espe-
cially arisk if the child is in the immediate
vicinit yofthe front-passenger airbag when
it deploys.
R never secur eachild on the front-passenger
seat in arearward-facing child restraint sys-
tem. Only secur earearward-facing child
restraint system on asuitable rear seat.
R alway smove the front-passenger seat to
the rearmost position if you secur eachild
in af orward-facing child rest raint system
on the front-passenger seat.
The front-passenger airbag is not disabled:
R on vehicles without automatic child seat
recognition on the front-passenger seat
R in vehicles with automatic child seat rec-
ognition in the front-passenger seat, if no

WARNING
If the 4 PASSENGE RAIRBA GO FF indica-
tor lamp does not light up whe nthe child
restraint system is fitted, the fr ont-passenger
airbag has not been disabled. If the fr ont-
pa ssenger airbag deploys, the chil dcould be

Proceed as follows:
R do not use arearward-facin gchild restraint
system on the fr ont-passengers eat.
R fit arearward-facing child restraint system
on asuitable rear seat.
or R
only use aforward-facing child rest raint
system on the front-passenger seat and
move the front-passenger seat to the rear-
most position.
R have the automatic child seat recognition
checked at aqualified specialist workshop.
To ensure that the automatic child seat rec-
ognition on the front-passenger seat func-
tions/communicates correctly, never place
objects, e.g. acushion, under the child
restraint system. The entire base of the child
restraint system must alway srest on the seat
cushion. An incorrec tlyf itted child restraint
system cannot perfor mits intended protec-
tive function in the event of an accident, and
could lead to injuries. G
WARNING
Do not place electronic devices on the front-
passenger seat, e.g.:
R laptops, when switched on
R mobile phones
R cards with transponders, e.g. ski passes or
access cards
Signals from electronic equipment can cause
interference in the automatic child seat rec-
ognition sensor system. Thi scan lead to a
system malfunc tion. This may cause the
