59
The front passenger 
front air bag off 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 passen-
ger seat.
The system is malfunction-
ing.
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 push-
ing against roof etc.). The system may recognize such 
forces as supplemental weight.
If the front passenger front air bag off indicator lamp re-
mains out, have the system checked as soon as possible 
by an authorized Mercedes-Benz Light Truck Center. Do 
not transport a child on the front passenger seat until 
the system has been repaired.
Also note any messages in the multifunction display and 
follow corrective steps (
page 440).
Warning!
