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 169) 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 155) or
buttonj,k,ÿ, orè on the
multifunction steering wheel.
Other messages of high priority and mes-
sages of less immediate priority can be
cleared from the multifunction display
using the reset button (
page 155) or
buttonj,k,ÿ, orè on the
multifunction steering wheel. They are
then stored in the vehicle status message
memory (
page 169). Remember that
clearing a message will only make the mes-
sage disappear. Clearing a message will
not correct the condition that caused the
message to appear.
Warning!G
All categories of messages contain
important information which should be
taken note of and, where a malfunction is
indicated, addressed as soon as possible at
an authorized Mercedes-Benz Light Truck
Center.
Failure to repair condition noted may cause
damage not covered by the Mercedes-Benz
Limited Warranty, or result in property dam-
age or personal injury.

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 453)
Symbol messages (page 469)
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.

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.

currently unavailable
See Operator’s ManualDistronic* is deactivated because
the functionality is impaired by
external interferences, e.g.
high-frequency sources such as toll
stations, speed measuring systems
etc.Leave the area of the external interference.
Activate the Distronic* again (page 268),
when the message
DISTRONIC available
again
appears.
Distronic* is deactivated because
the Distronic* sensor has not
sensed any other vehicles or
objects, e.g. road sign or such, for a
long time.Try to activate Distronic* again
(

the Distronic* cover in the
radiator grille is dirty
the functionality is impaired by
heavy precipitation or fog
Clean the Distronic* cover in the radiator
grille (
page 430).
Restart the vehicle.
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.
