The front passenger front
air bag off indicator lamp
does not illuminate and/or
does not remain illuminat-
ed with the weight of a typ-
ical 12-month-old child in a
standard child restraint or
less on the front passen-
ger seat.
The system is malfunctioning. ̈ Make sure there is nothing between seat cushion and child seat and
check installation of the child seat.
̈ Make sure no objects applying supplemental weight onto the seat
are present.
̈ Make sure no objects which apply forces to the seat are present
(e.g. objects such as books, briefcases etc. lodged behind or around
the seat, head restraints pushing against roof etc.). The system may
recognize such forces as supplemental weight.
̈ If the front passenger front air bag off indicator lamp remains out,
have the system checked as soon as possible by an authorized
Mercedes-Benz Center. Do not transport a child on the front pas-
senger seat until the system has been repaired.
̈ Also read and observe any messages in the multifunction display
and follow corrective steps (
୴ page 612).

has been repaired.
