356 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 141) 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 26) or
buttonj, k, è orÿ 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 or buttonj,
k, è orÿ on the multifunction
steering wheel. They are then stored in the
vehicle status message memory
(
page 153). Remember that clearing a
message will only make the message
disappear. Clearing a message will not
correct the condition that caused the mes-
sage to appear.

tant information which should be taken note
of and, where a malfunction is indicated,
addressed as soon as possible at an autho-
rized Mercedes-Benz Center.
