Problem
Possible cause
Suggested solution
75The indicator lamp does not illuminate
and/or does not remain illuminated with
the weight of a typical 12-month-old child in
a standard child restraint or less on the
front passenger seat.
The system is malfunctioning.
Make sure that there is nothing between seat cush-
ion and child seat and check installation of the child
seat.
Make sure that no objects applying supplemental
weight onto the seat are present.
Make sure that no objects which apply forces to the
seat are present (e.g. objects such as books, brief-
cases etc. lodged behind or around the seat, head
restraints pushing against roof etc.). The system
may recognize such forces as supplemental weight.
If the light remains out, have the system checked as
soon as possible by an authorized Mercedes-Benz
Center. Do not transport a child on the front passen-
ger seat until the system has been repaired.
Also note any messages in the multifunction display
and follow corrective steps (
page 369).
Warning!

repaired.
