On the pages that follow, you will find a
compilation of the most important warning
and malfunction messages that may
appear in the multifunction display. High
priority messages appear in red color.
For your convenience the messages are
divided into two sections:
Text messages (page 316)
Symbol messages (page 327)
Warning!G
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, do so with
added caution. Contact an authorized
Mercedes-Benz Center as soon as possible.
iSwitching on the ignition causes all instru-
ment cluster lamps (except high beam headlamp
indicator lamp and turn signal indicator lamps
unless activated) as well as the multifunction
display to come on. Make sure the lamps and
multifunction display are in working order before
starting your journey.
