Notes on display messages

The display shows warnings, malfunctions
or additional information. A warning tone
also sounds with some display messages.
Messages from all categories can contain
important information that must be
observed. Have error messages checked at a
Mercedes-Benz Service Centre as soon as
possible. If an error message is not followed
up with a repair, this can lead to damage that
is not covered by the Mercedes-Benz Limited
Warranty including injuries or material
damage.
