R in the fuel injection system
R in the exhaust system
R in the ignition system (for vehicles with gasoline engines)
R in the fuel system
The emission limit values may be exceeded and the engine may be in emergency mode.
X Visit a qualified specialist workshop immediately.
In some states, you must immediately visit a qualified specialist workshop as soon as the yellow Check Engine warning lamp lights up. This is due to the legal require-
ments in effect in these states. If in doubt, check whether such legal regulations
apply in the state in which you are currently driving. 00B6

General notes
The multimedia system section in this Opera-
tor's Manual describes the basic principles for
operation. More information can be found in the Digital Operator's Manual. Important safety notes
G
WARNING
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 whenoperating the multimedia system.
The multimedia system calculates the route to
the destination without taking the following into
account, for example:
R traffic lights
R stop and yield signs
R parking or stopping restrictions
R road narrowing
R other 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:
R a diverted route
R the 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 install 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). G
WARNING
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. 264
Function restrictionsMultimedia system
Observe the following notes on securing loads:
R Secure the load using the cargo tie-down
rings.
R Distribute the load on the cargo tie-down
rings evenly.
R Do not use elastic straps or nets to secure a
load, as these are only intended as an anti-slip protection for light loads.
R Do not route tie-downs across sharp edges or
corners.
R Pad sharp edges for protection. There are four cargo tie-down rings

WARNING
The bag hooks cannot restrain heavy objects
or items of luggage. Objects or items of lug-
gage could be flung around and thereby hit
vehicle occupants when braking or abruptly
changing directions. There is a risk of injury.
Only hang light objects on the bag hooks.
Never hang hard, sharp-edged or fragile
objects on the bag hooks.
! The bag hook can bear a maximum load of
6.6lbs (3kg) and should not be used to secure
a load. There is one bag hook on either side of the cargo
compartment.
