Introduction
The printed Owner's Manual provides informa-
tion about the safe operation of your vehicle.
The Digital Owner's Manual additionally
describes further functions and equipment fit-
ted in your vehicle. The functions of the vehicle
and multimedia system are described in the Dig-
ital Owner's Manual. You can call up the Digital
Owner's Manual via the multimedia system.
i You will not incur any costs when calling up
the Digital Owner's Manual. The Digital Own-
er's Manual works without connecting to the
Internet.
There are three ways to access the topics of the Digital Owner's Manual:

vehicle "virtually". Starting from either the
vehicle exterior view or interior view, you can access many of the different topics covered
by the Digital Owner's Manual. To access the
vehicle interior section, select the "Vehicle
interior" view.
R Keyword search
The keyword search allows you to search for a
keyword by entering characters. Further
