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
No further messages can be displayed if the
instrument cluster and/or the multi-func-
tion display fails.
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 vehicle's handling character-
istics may be affected. Adjust 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.
When you stop and park the vehicle, please
observe the instructions provided for HOLD
(Y page 155) and parking ( Ypage 113).
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 mem-
ory (Ypage 131). Practical advice

Risk of accident and injury
The operating safety of the vehicle could be impaired if service work is carried out incorrectly. There is a risk that you could lose control of
the vehicle and cause an accident. The safety systems may no longer be able to protect you or others as they are designed to do.
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
