iblew hen you open the front-passenger

Risk of injury
If the 4 PASSENGER AIRBA GOFF indica-
tor lamp doe snot light up when the child
restraint system is fitted, the front-passenger
front airbag has not been disabled. If the front-
passenger front airbag deploys, the child
coul dbes eriously or even fatally injured.
Proceed as follows:
R do not use arearward-facing child restraint
system on the front-passenger seat.
R fit arearward-facing child restraint system
on asuitable rear seat.
or
R only use aforward-facing child restraint
system on the front-passenger seat and
mov ethe front-passenger seat to its rear-
most position.
R hav ethe automatic chil dseat recognition
checked at aqualified specialist workshop.
To ensure that the automatic child seat rec-
ognitio nonthe front-passenger seat func-
tions/communicates correc tly, never place
objects (such as acushion) under the child
restraint system. The entire base of the child restraint system must always rest on the seat
cushion. An incorrectly fitted child restraint
system cannot perform its intended protec-
tive function in the event of an accident, and
could lead to injuries.
i If the front-passenger front airbag is dis-
abled by the automatic child seat recogni-
tion, the following remain activated on the
front-passenger side:
R the sidebag
R Cabriolet: the headbag
R Coupé :the windowbag
R the belt tensioners G
Risk of injury
Do not plac eelectronic devices on the fron t-
passenger seat, e.g.:
R laptops, when switched on
R mobile phones
R cards with transponders, e.g. ski passes or
access cards
Signal sfrom electroni cequipmen tcan cause
interference in the automatic child seat rec-
ognition senso rsystem. This can lead to a
syste mmalfunction. This may cause the
4 PASSENGER AIRBA GOFF indicator
lamp to light up without there being achild
seat with automatic chil dseat recognition fit-
ted, and the front-passenger front airba gwill
not deploy during an accident .Itisalso pos-
sible that the 6SRS warnin glamp lights
