General notes
The multimedia system section in this Opera-
tor's Manual describes the basic principles for
operation. More information can be found in theDigital Operator's Manual.
Important safety notes
GWARNING
If you operate information systems and com-
munication equipment integrated in the vehi-
cle when driving, you may be distracted from
the traffic situation. You could also lose con-
trol of the vehicle. There is a risk of an acci-
dent.
Only operate this equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
You must observe the legal requirements for the
country in which you are currently driving when
operating the multimedia system.
The multimedia system calculates the route to
the destination without taking the following into
account, for example:
Rtraffic lights
Rstop and yield signs
Rparking or stopping restrictions
Rroad narrowing
Rother road and traffic rules and regulations
The multimedia system may give incorrect nav-
igation recommendations if the actual street/
traffic situation does not correspond with the
digital map's data.
For example:
Ra diverted route
Rthe road layout or the direction of a one-way
street has been changed
For this reason, you must always observe road
and traffic rules and regulations during your
journey. Road and traffic rules and regulations
always have priority over multimedia system
driving recommendations. Navigation announcements are intended to
direct you while driving without diverting your
attention from the road and driving.
Please always use this feature instead of con-
sulting the map display for directions. Looking
at the icons or map display can distract you from
traffic conditions and driving, and increase the
risk of an accident.
This equipment complies with FCC radiation
exposure limits set forth for uncontrolled equip-
ment and meets the FCC radio frequency (RF)
Exposure Guidelines in Supplement C to OET65.
This equipment has very low levels of RF energy
that is deemed to comply without maximum
permissive exposure evaluation (MPE). How-
ever, it is
recommended to insta

ll it at a distance
of at least 8 inches (approx. 20 cm) between the
radiation source and a person's body (not
including limbs such as hands, wrists, feet and
legs).
GWARNING
Modifications to electronic components, their software as well as wiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardize the operating safety of
the vehicle. There is an increased risk of an
accident and injury.
Never tamper with the wiring as well as elec-
tronic components or their software. You
should have all work to electrical and elec-
tronic equipment carried out at a qualified
specialist workshop.
Function restrictions
For safety reasons, some functions are restric-
ted or unavailable while the vehicle is in motion.
You will notice this, for example, because either
you will not be able to select certain menu items
or a message will appear to this effect.

Important safety notes
GWARNING
If objects in the passenger compartment are
stowed incorrectly, they can slide or be
thrown around and hit vehicle occupants. In
addition, cup holders, open stowage spaces
and mobile phone brackets cannot always
retain all objects they contain. There is a risk of injury, particularly in the event of sudden
braking or a sudden change in direction.
RAlways stow objects so that they cannot be
thrown around in such situations.
RAlways make sure that objects do not pro-
trude from stowage spaces, parcel nets or
stowage nets.
RClose the lockable stowage spaces before
starting a journey.
RAlways stow and secure heavy, hard, poin-
ted, sharp-edged, fragile or bulky objects in
the trunk.
GWARNING
The heating elements of the cup holder can
become very hot. You could burn yourself on
them.
There is a risk of injury.
Do not touch the hot heating elements of the
cup holder. Always make sure that children
cannot access the hot heating elements of the
cup holder. Never leave children unsuper-
vised in the vehicle.
!Only use the cup holders for containers of
the right size and which have lids. The drinks could otherwise spill.
!Do not expose drinks bottles in the cup
holder in the center console to continuous,
strong and direct sunlight. The passenger
compartment in the area of the center con-
sole can otherwise be damaged by the con-
centrated and reflected sunlight.
