304 Practical hintsWhat to do if ...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 124) 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 29). Other messages of high priority and
messages of less immediate priority can
be cleared from the multifunction display
using the reset button. They are then
stored in the vehicle status message mem-
ory (
page 124). Remember that clearing
a message will only make the message dis-
appear. Clearing a message will not cor-
rect 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 Center.
Failure to repair condition noted may cause
damage not covered by the Mercedes-Benz
Limited Warranty, or result in property
damage or personal injury.
Warning!
G
No messages will be displayed if either the
instrument cluster or the multifunction
display is inoperative.
Contact your nearest authorized
Mercedes-Benz Center.iSwitching on the ignition causes all in-
strument cluster lamps (except high
beam headlamp indicator lamp and
turn signal indicator lamps unless acti-
vated) as well as the multifunction dis-
play to come on. Make sure the lamps
and multifunction display are in work-
ing order before starting your journey.

offline!
The consumer battery has in-
sufficient voltage and can no
longer supply the convenience
functions.
The electrical consumers will come back online as soon as
on-board voltage is sufficient.
Battery/
Alternator
Stop vehicle!
The battery or the alternator is
malfunctioning.
The SBC brake system requires
electrical energy and therefore
has only limited operation.
Considerably greater brake
pedal force is required and the
stopping distance is increased.
Stop the vehicle as soon as it is safe to do so. Adjust driv-
ing to be consistent with reduced braking responsive-
ness.
Notify an authorized Mercedes-Benz Center immediate-
ly.
Observe the additional messages in the instrument clus-
ter.
Failure to follow these instructions increases the risk of an
accident.

system requires electrical ener-
gy and may be operating with
restricted capability. Consider-
ably greater brake pedal force
is required and the stopping
distance is increased.
Stop your vehicle safely immediately and check the
poly-V-belt.
If it is broken:
Do not continue to drive. Otherwise the engine will
overheat due to an inoperative water pump which
may result in damage to the engine. Notify an
authorized Mercedes-Benz Center.
If it is in order:
Drive immediately to the nearest authorized
Mercedes-Benz Center. Adjust driving to be consis-
tent with reduced braking responsiveness.
Observe the additional messages in the instrument
cluster.
There is a malfunction in the
electronic system.
