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 415)
Symbol messages (page 427)
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

Replacing bulbs
Notes on bulb replacement
Only use 12-volt bulbs of the same type
and with the specified watt rating.
Switch lights off before changing a bulb
to prevent short circuits.
Always use a clean lint-free cloth when
handling bulbs.
Your hands should be dry and free of oil
and grease.
If the newly installed bulb does not
come on, visit an authorized
Mercedes-Benz Light Truck Center.Have the LEDs and bulbs for the following
lamps replaced by an authorized
Mercedes-Benz Light Truck Center:
the additional turn signal lamps in the
exterior rear view mirrors
the high mounted brake lamp
the Bi-Xenon* low beam lamps
the Bi-Xenon high beam flasher spot-
light*
Warning!G
Bulbs and bulb sockets can be very hot.
Allow the lamp to cool down before chang-
ing a bulb.
Keep bulbs out of reach of children.
Halogen lamps contain pressurized gas.
A bulb can explode if you:
touch or move it when hot
drop the bulb
scratch the bulb
Wear eye and hand protection.
Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb or repair the
lamp and its components. We recommend
that you have such work done by a qualified
technician.
!Do not replace the LEDs yourself. You could
otherwise damage the LEDs or parts of the vehi-
cle. Only have the LEDs replaced by a an autho-
rized Mercedes-Benz Light Truck Center.
iReplacing the bulbs for the front lamps is a
technically complex process. For your conve-
nience, we recommend that you have this work
carried out by an authorized Mercedes-Benz
Light Truck Center.
Have the headlamp adjustment checked
regularly.
