Risk of accident
No further messages can be displayed if the
instrument cluster and/or the multi-function
display fails.
This means that you will not see information
about the driving situation, such as the speed,
outside temperature, warning/indicator
lamps, display messages or system failures.
The vehicle's handling characteristics may be
affected. Adjust your driving style and speed
accordingly.
Immediately consult 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.
Before starting a journey, check that the
warning and indicator lamps are operating
correctly.
X Turn the key to position 2in the ignition
lock.

the main-beam indicator lamp and the turn
signal indicator lamps) light up and the
multi-function display is activated.
The following tables contain all the display
messages. To make it easier for you to find
the relevant display message, the display
messages are divided into text messages
(Y page 177) and symbol messages
(Y page 182). Text messages
