General notes
The multimedia system section in this manual
describes the basicprinciples for operation.
More information can be found in the Digital
Operator's Manual.
Important safety notes
GWARNING
If you operate information systems and com-
municatio nequipment integrated in the vehi-
cle whil edriving, you wil lbedistracted from
traffic conditions. You could also lose control
of the vehicle .There is arisk of an accident.
Only operate the 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 legalr equirements for the
country in which you are currently driving when
operating the multimedia system.
The multimedia system calculates the route to
the destination withou ttaking the following into
account, for example:
Rtraffic lights
Rstop and yield signs
Rparking or stopping restrictions
Rroad narrowing
Rother road and traffic rule sand 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:
Rad iverted route
Rthe road layout or the direction of aone-way
street has been changed
For this reason, you must alwayso bserve road
and traffic rule sand regulations during your
journey. Roa dand traffic rule sand regulations
alwaysh ave priority over multimedia system
driving recommendations.
Navigation announcements are intended to
direct you whil edriving withou tdiverting your
attention from the road and driving. Please alwaysu
se 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 radi ofrequency (RF)
Exposure Guidelines in Supplement CtoOET65.
This equipment has very low levelsofRFe nergy
that is deemedtoc omply withoutmaximum
permissive exposure evaluation (MPE). But it is

ha
t it shoul dbeinstalled and oper-
ated with at least 8inches( 20 cm) and more
between the radiator and aperson's body
(excluding extremities: hands, wrists, fee tand
legs.)
GWARNING
Modifications to electronic components ,their
software as well as wiring can impai rtheir
functio nand/or the functio nofothernet-
worked components .Inparticular, systems
relevant to safety could also be affected. As a
result, thes emayno longer functio nasinten-
de da nd/or jeopardize the operating safety of
the vehicle. There is an increased ris kofan
accident and injury.
Never tamper with the wiring as well as elec-
