340 Operation
Maintenance
Resetting the maintenance service
indicator
In the event that the maintenance service
on your vehicle is not carried out by an
authorized Mercedes-Benz Center, you can
have the maintenance service indicator
reset. The automotive maintenance facility
carrying out the maintenance service will
find the information for resetting the
maintenance service indicator in the
maintenance-relevant information for your
vehicle. Such information is available from
either your authorized Mercedes-Benz
Center or directly from Mercedes-Benz.i
If the battery is disconnected, the days
of disconnection will not be included in
the count shown by the maintenance
service indicator. To arrive at the true
maintenance service deadline, you will
need to subtract these days from the
days shown in the maintenance service
indicator message or maintenance ser-
vice indicator display.
Do not confuse the maintenance
service indicator with the engine oil
level indicatorN.
i
If the maintenance service indicator
was inadvertently reset, have an
authorized Mercedes-Benz Center
correct it.
Only reset if the proper maintenance
service has been performed. Resetting
the system without performing the
proper service as called for by the
maintenance service indicator will
result in engine damage and/or other
vehicle damage not covered by the
Mercedes-Benz Limited Warranty.

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 134) 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 122) or
button j, k, ÿ, orè on the
steering wheel.
Other messages of high priority and
messages of less immediate priority can
be cleared from the multifunction display

page 122) or
button j, k, ÿ, orè on the
steering wheel. They are then stored in the
vehicle status message memory
(

message will only make the message dis-
appear. Clearing a message will not cor-
rect the condition that caused the
message to appear.

important information which should be
taken note of and, where a malfunction is
indicated, addressed as soon as possible at
