GWARNING
Tire pressures that are too low pose the following hazards:
Rthey may burst, especially as the load and vehicle speed increase.
Rthey may wear excessively and/or unevenly, which may greatly impair tiretraction.
Rthe driving characteristics, as well as steering and braking, may be greatlyimpaired.
There is a risk of an accident.

General notes
The multimedia system section in this Opera-tor's Manual describes the basic principles foroperation. More information can be found inthe Digital Operator's Manual.
Important safety notes
GWARNING
If you operate information systems and com-
munication equipment integrated in the
vehicle when driving, you may be distracted
from the traffic situation. You could also
lose control of the vehicle. There is a risk of
an accident.
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 equipment when the vehicle is station-
ary.
You must observe the legal requirements forthe country in which you are currently drivingwhen operating the multimedia system.
The multimedia system calculates the route tothe destination without taking the followinginto 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 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 youfrom traffic conditions and driving, andincrease the risk of an accident.
This equipment complies with FCC radiationexposure limits set forth for uncontrolledequipment and meets the FCC radio frequency(RF) Exposure Guidelines in Supplement C toOET65.
This equipment has very low levels of RFenergy that is deemed to comply without maxi-mum permissive exposure evaluation (MPE).However, it is recommended to install it at adistance of at least 8 inches (approx. 20 cm)between the radiation source and a person'sbody (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
networked components. In particular, sys-
tems relevant to safety could also be affec-
ted. As a result, these may no longer func-
tion as intended and/or jeopardize the oper-
ating 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 inmotion. You will notice this, for example,because either you will not be able to selectcertain menu items or a message will appearto this effect.
