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 435)
Symbol messages (page 451)
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 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 indica-
tor lamps unless activated) as well as the multi-
function display to come on. Make sure the
lamps and multifunction display are in working
order before starting your journey.
