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.
For your convenience the messages are
divided into two sections:
Text messages (page 451)
Symbol messages (page 466)
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, please do so
with added caution. Visit an authorized
Mercedes-Benz Light Truck Center as soon
as possible.
iSwitching on the ignition causes all
instrument 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.

stations, speed measuring systems
etc.Leave the area of the external interference.

heavy precipitation or fog
Clean the Distronic* cover in the radiator

Distronic* becomes operational again without
the engine being restarted when
dirt on the radiator grille has fallen off while
driving (e.g. slush or snow)
the system recognizes full sensor
availability due to lessening rain or because
the road is drying, for example
the message in the multifunction display
disappears
You can then operate Distronic* as usual again.
