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 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 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 (

Vehicle status messages in the multifunction display
Warning and malfunction messages
appear in the multifunction display located
in the instrument cluster.
Certain warning and malfunction messag-
es are accompanied by an audible signal.
Address these messages accordingly and
follow the additional instructions given in
this Operator’s Manual.
Selecting the vehicle status message
memory menu in the control system
(page 159) displays both cleared and
uncleared messages.
High-priority messages appear in the
multifunction display in red color.Certain messages of high priority cannot
be cleared from the multifunction display
using the reset button (
page 24) or
buttonj,k,ÿ, orè on the
multifunction steering wheel.
Other messages of high priority and mes-
sages of less immediate priority can be
cleared from the multifunction display
using the reset button (page 24) or
buttonj,k,ÿ, orè on the
multifunction steering wheel. They are
then stored in the vehicle status message
memory (
page 159). Remember that
clearing a message will only make the mes-
sage disappear. Clearing a message will
not correct the condition that caused the
message to appear.
