Children less than 1.50 mtall or under 12
years of age cannot wear the seat belts
properly. Therefore, they always should be
secured in asuitable child restraint system
on asuitable vehicle seat. You can find
more information under "Children in the
vehicle" in the "Safety" section of the Own-
er's Manual. Follow the manufac turer's
installatio ninstructions whe nfitting the
child restraint system.
R Do not secure any objects with aseat belt
if the seat belt is also being used by one of
the vehicle's occupants. G
Risk of injury
The seat belt does not offer the intended level
of protection unless the back rest is almost
ver tical. Under certain circumstances, this
coul dcause severe or even fatal injuries in the
event of an accident.
Befor estarting ajourney, mak esure that the
seat is properly adjusted and that the back-
rest is almost vertical. G
Risk of injury
Ad irtyo rdamaged seat belt or aseat belt that
has been subjected to aload in an accident
or which has been modified no longer offers
the intended level of protection. Un dercertain
cir cumstances, this could caus esever eor
even fatal injuries in the even tofanaccident.
For thi sreason, check regularly that the seat
belts are not damaged or dirty.
Alway shaved am aged sea tbelts or seat belts

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:

Signal sfrom electroni cequipmen tcan cause
