Problem
Possible cause/consequence
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.
Read and observe messages in the multifunction
display and follow corrective steps (
page 393).

386 Practical hintsWhat to do if …Vehicle status messages in the multi-function display
Warning and malfunction messages ap-
pear 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 153) displays both cleared and
uncleared messages.
High-priority messages appear in the mul-
tifunction display in red color.Certain messages of high priority cannot
be cleared from the multifunction display
using the reset button (
page 150) or
buttonj, k, ÿ or è on the
multifunction steering wheel.
Other messages of high priority and mes-
sages of less immediate priority can be
cleared from the multifunction display us-
ing the reset button (
page 150) or
buttonj, k, ÿ or è on the
multifunction steering wheel. They are
then stored in the vehicle status message
memory (
page 162). 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.
Warning!
G
All categories of messages contain impor-
tant information which should be taken note
of and, where a malfunction is indicated, ad-
dressed as soon as possible at an autho-
rized Mercedes-Benz Center.

instrument cluster or the multifunction dis-
play is inoperative.
