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

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-

these messages continuously until the cau-
ses of the messages have been remedied.
