2005 MERCEDES-BENZ C320 Reset

294 OperationMaintenanceResetting 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.
iIf 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.

309 Practical hints
What 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 130) 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 117).Other messages of high priority and
messages of less immediate priority can
be cleared from the multifunction display
using the reset button (
page 117). They
are then stored in the vehicle status mes-
sage memory (
page 130). Remember
that clearing a message will only make the
message disappear. Clearing a message
will not correct the condition that caused
the message to appear.
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. High
priority messages appear in red color.
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 ignition, causes all lamps
as well as the multifunction display to
come on. Make sure that they are all in
working order before starting your jour-
ney.
