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.
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.

The on-board computer saves certain dis-
play messages in the message mem-
ory (Ypage 103). Practical advice

Theyellow ABS warning
lamp comes on while the
engine is running. G
Risk of accident
ABS has been deactivated due to
a malfunction. ESP ®
, BAS and the
tyre pressure monitor* are there-
fore also deactivated.
The brake system continues to
function normally, but without
electronic support. Therefore,
the wheels could lock if you brake
hard.
If the ABS control unit is faulty,
there is also a possibility of mal-
functions in other systems, such
as the ultrasonic reversing aid ®
,
the navigation system ®
or the
automatic transmission. X
Drive on carefully.

Theyellow ABS warning
lamp comes on while the
engine is running. G
Risk of accident
ABS has been deactivated due to
undervoltage. It is possible that
the battery is not being charged.
Therefore, the following systems
are, for example, also deactiva-
ted: ESP ®

pressure monitor*.
The brake system continues to
function normally, but without
electronic support. The wheels
could therefore lock if you brake
hard. X
Switch off consumers that are not required, e.g. reading lamps,
interior lighting, etc.
ABS will be available again as soon as the vehicle's electrical sys-
tem voltage increases.
X Observe the additional messages in the multi-function display
(Y page 194). You have engaged the differential
