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

Risk of accident and injury
The operating safety of your vehicle could be compromised if service work is carried out improperly. You could lose control of the vehicle,
thereby causing an accident. Safety systems may also not be able to protect you or others as intended.
Always have maintenance work carried out at a qualified specialist workshop which has the necessary specialist knowledge and tools to
carry out the work required.
Mercedes-Benz recommends that you use a Mercedes-Benz Service Centre for this purpose.
In particular, work relevant to safety or on safety-related systems must be carried out at a qualified specialist workshop. Display messages Possible cause/consequence Possible solution
