Notes
The on-board computer shows warnings or
malfunctions in the multi-function display.
Certain display messages are accompanied
by a warning tone or a continuous tone.
The multi-function display shows high-priority
display messages in red. In the following
tables, these display messages are printed in
red.
Please respond in accordance with the dis-
play messages and follow the additional
notes in this Owner's Manual. G
Risk of accident
If the instrument cluster or the multi-func-
tion display fails, no messages can be dis-
played.
This means that you will not see information
about the driving situation, such as the
speed, outside temperature, warning/indi- cator lamps, display messages or system
failures. The handling characteristics may
be affected. Adapt your driving style and
speed accordingly.
Immediately consult a qualified specialist
workshop which has the necessary special-
ist knowledge and tools to carry out the
work required. Mercedes-Benz recom-
mends that you use a Mercedes-Benz
Service Centre for this purpose. In particu-
lar, work relevant to safety or on safety-
related systems must be carried out at a
qualified specialist workshop.
Before starting a journey, check that the
warning and indicator lamps are operating
correctly. X
Turn the key to position 2in the ignition
lock.
or
X Press the KEYLESS GO button* twice.
All warning and indicator lamps (except for
the turn signal indicator lamps) light up and
the multi-function display is activated.
The following tables contain all the display
messages.
Hiding display messages After a few seconds, the on-board computer
automatically hides some low priority display
messages. Other messages remain visible in
the multi-function display until you hide them
yourself.
Some high priority display messages cannot
be hidden. The multi-function display shows
these messages continuously until the cau-
ses of the messages have been remedied.
Use the buttons on the multi-function steer-
ing wheel.
X
Use the è,·,jork button
to select another display.
The on-board computer saves certain dis-
play messages in the message memory
(Y page 128). Practical advice
