positioning of the child restraint system
(Y page 63) in addition to the child restraint
system manufacturer's installation and oper-
ating instructions.

passenger seat as far back as possible.
Always make sure that the shoulder belt strap is correctly routed from the vehicle belt outlet to the shoulder belt guide on the child
restraint system. The shoulder belt strap
must be routed forwards and downwards
from the vehicle belt outlet. If necessary,
adjust the vehicle belt outlet and the front-
passenger seat accordingly.

Problems with automatic child seat recognition
Problem
Possible causes/consequences and
M
MSolutions The PASSENGER AIR
BAG OFF indicator
lamp on the centre con-
sole is lit. A special Mercedes-Benz child restraint system with a trans-
ponder for automatic child seat recognition has been fitted to the
front-passenger seat. The front-passenger front airbag has there- fore been disabled as desired. There is no child restraint system fitted to the front-passenger
seat. Automatic child seat recognition is malfunctioning, for exam-
ple due to electronic devices on the front-passenger seat.
X Remove electronic equipment from the front-passenger seat,
e.g.:
R laptop
R mobile phone
R a card with a transponder, such as a ski pass or access pass
If the PASSENGER AIR BAG OFF indicator lamp remains lit, the
front-passenger seat may not be used. X Visit a qualified specialist workshop. The
6 restraint sys-
tem warning lamp
lights up and/or the
PASSENGER AIR BAG
OFF indicator lamp
does not light up briefly
when you switch the
ignition on. G
