General notes
The multimedia system section in this Opera-tor's Manual describes the basic principles foroperation. 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 thecountry in which you are currently driving whenoperating the multimedia system.
The multimedia system calculates the route tothe destination without taking the following intoaccount, 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 thedigital map's data.
For example:
Ra diverted route
Rthe road layout or the direction of a one-waystreet has been changed
For this reason, you must always observe roadand traffic rules and regulations during yourjourney. Road and traffic rules and regulationsalways have priority over multimedia systemdriving recommendations.
Navigation announcements are intended todirect you while driving without diverting yourattention from the road and driving.
Please always use this feature instead of con-sulting the map display for directions. Lookingat the icons or map display can distract you fromtraffic conditions and driving, and increase therisk of an accident.
This equipment complies with FCC radiationexposure 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 energythat is deemed to comply without maximumpermissive exposure evaluation (MPE). How-ever, it is recommended to install it at a distanceof at least 8 inches (approx. 20 cm) between theradiation source and a person's body (notincluding limbs such as hands, wrists, feet andlegs).
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 eitheryou will not be able to select certain menu itemsor a message will appear to this effect.
