Display messages
Introduction
Display messages with graphic symbols are simplified in the Operator's Manual and may differ
from the symbols in the display. The display shows high-priority messages in red. For certain
display messages a warning tone also sounds.
Please respond in accordance with the display messages and follow the additional notes in this
Operator's Manual.
You can use the0076button on the multifunction steering wheel to hide low-priority mes-
sages. The display messages are stored in the message memory and can be called up as for as
long as the ignition remains switched on (
Ypage 113). When the ignition is turned off, the
message memory is deleted and no display messages are stored. The cause of a display message
should be remedied as soon as possible.
High-priority display messages cannot be hidden. The multifunction display shows these
messages continuously until the causes for the messages have been remedied.

Information about Service
Resetting the service display
!Have service work carried out as descri-
bed in the Maintenance Booklet. This may
otherwise lead to increased wear and dam-
age to the major assemblies or the vehicle.
A qualified specialist workshop, e.g. a smart center, will reset the service interval dis-
play after the service work has been carried
out. You can also obtain further information
on maintenance work, for example.
Special service requirements
The prescribed service interval is based on
normal operation of the vehicle. Service work
will need to be performed more often if the
vehicle is operated under arduous conditions
or increased loads, for example:
Rregular city driving with frequent inter-
mediate stops
Rif the vehicle is primarily used to travel
short distances
Rfor frequent operation in mountainous ter-
rain or on poor road surfaces
Rif the engine is often left idling for long
periods
In these or similar operating conditions,
have, for example, the air filter, engine oil
and oil filter changed more frequently. The
tires must be checked more frequently if the
vehicle is operated under increased loads.
You can obtain further information at a
qualified specialist workshop, e.g. a smart
center.
Driving abroad
An extensive smart service network is also
available in other countries. For further
information inquire at any smart center.
