370 Practical hintsWhat to do if …?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 151) 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 140) or but-
ton k,j, è, orÿ on the
steering wheel.
Other messages of high priority and
messages of less immediate priority can
be cleared from the multifunction display
using the reset button (page 140) or but-
ton k,j, è, orÿ on the
steering wheel. They are then stored in the
vehicle status message memory
(
page 151). Remember that clearing a
message will only make the message dis-
appear. Clearing a message will not cor-
rect the condition that caused the
message to appear.

taken note of and, where a malfunction is
indicated, addressed as soon as possible at

compilation of the most important warning
and malfunction messages that may
appear in the display.
High priority messages appear in red color.
For your convenience the messages are
divided into two sections:

No messages will be displayed if either the
instrument cluster or the multifunction
display is inoperative.
As a result, you will not be able to see infor-
mation about your driving conditions, such
as speed or outside temperature, warn-
ing/indicator lamps, malfunction/warning
messages or the failure of any systems.
Driving characteristics may be impaired.
If you must continue to drive, please do so
with added caution. Visit an authorized
Mercedes-Benz Center as soon as possible.

display to come on. Make sure the
lamps and the multifunction display are
in working order before starting your
