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 128) 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) or
button j, k, ÿ, or è on the
multifunction steering wheel.
Other messages of high priority and
messages of less immediate priority can
be cleared from the multifunction display
using the reset button or button j,
k, ÿ, or è on the multifunction
steering wheel. They are then stored in the
vehicle status message memory
(
page 128). 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.
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.

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, do so with
added caution. Contact an authorized
Mercedes-Benz Center as soon as possible.
