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 while driving, you will be distracted from
traffic conditions. You could also lose control
of the vehicle. There is a risk 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 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: 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 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).
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.
If you make any changes to the vehicle elec-
tronics, the general operating permit is ren-
dered invalid.
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.Function restrictions 227

Loading guidelines
G WARNING
If objects, luggage or loads are not secured or
not secured sufficiently, they could slip, tip
over or be flung around and thereby hit vehicle
occupants. There is a risk of injury, particu-
larly in the event of sudden braking or a sud-
den change in direction.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
G WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Exhaust
gases can enter the vehicle interior if the
trunk lid is open when the engine is running,
especially if the vehicle is in motion. There is a
risk of poisoning.
Always switch off the engine before opening
the trunk lid. Never drive with the trunk lid
open.
G WARNING
The exhaust tail pipe and tail pipe trim can
become very hot. If you come into contact
with these parts of the vehicle, you could burn
yourself. There is a risk of injury.
Always be particularly careful around the
exhaust tail pipe and the tail pipe trim. Allow
these components to cool down before touch-
ing them.
The handling characteristics of a laden vehicle
are dependent on the distribution of the load
within the vehicle.
Observe the following notes on loading and
transporting a load: R
Never exceed the maximum permissible
gross vehicle mass or the gross axle weight
rating for the vehicle (including occupants).
The values are specified on the vehicle iden- tification plate on the B-pillar of the driver's
door. R
The trunk is the preferred place to carry
objects. R
Position heavy loads as far forwards as pos-
sible and as low down in the trunk as possible. R
The load must not protrude above the upper
edge of the seat backrests. R
Always place the load against the rear or front
seat backrests. Make sure that the seat
backrests are securely locked into place. R
Always place the load behind unoccupied
seats if possible. R
Use the cargo tie-down rings and the parcel
nets to transport loads and luggage. R
Use cargo tie-down rings and fastening mate-
rials appropriate for the weight and size of the
load. R
Secure the load with sufficiently strong and
wear-resistan t tie-downs. Pad sharp edges for
protection.
Stowage areas
Stowage spaces
Important safety notes
G WARNING
If objects in the passenger compartment are
stowed incorrectly, they can slide or be
thrown around and hit vehicle occupants. In
addition, cupholders, 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. R
Always stow objects so that they cannot be
thrown around in such situations. R
Always make sure that objects do not pro-
trude from stowage spaces, parcel nets or
stowage nets. R
Close the lockable stowage spaces before
starting a journey. R
Always stow and secure heavy, hard, poin-
ted, sharp-edged, fragile or bulky objects in
the trunk.
Observe the loading guidelines ( Y

even if you have pressed the SOS button in an
emergency if: R
you see smoke inside or outside of the vehi-
cle, e.g. if there is a fire after an accident R
the vehicle is on a dangerous section of
road R
the vehicle is not visible or cannot easily be
seen by other road users, particularly when
dark or in poor visibility conditions
There is a risk of an accident and injury.
Leave the vehicle immediately in this or simi-
lar situations as soon as it is safe to do so.
Move to a safe location along with other vehi-
cle occupants. In such situations, secure the
vehicle in accordance with national regula-
tions, e. g. with a warning triangle.
General notes Observe the notes on system activation
( Y
page 242).
An emergency call is dialed automatically if an
air bag or Emergency Tensioning Device is trig-
gered. You cannot end an automatically trig-
gered emergency call yourself.
An emergency call can also be initiated man-
ually.
As soon as the emergency call has been initi-
ated, the indicator lamp in the SOS button
flashes. The Connecting Call message
appears in the multifunction display.
The audio output is muted.
Once the connection has been made, the Call
Connected message appears in the multifunc-
tion display. All important information on the emergency is
transmitted, for example: R
current location of the vehicle (as determined
by the GPS system) R
vehicle identification number R
information on the severity of the accident
Shortly after the emergency call has been initi-
ated, a voice connection is automatically estab-
lished between the Customer Assistance Center
and the vehicle occupants. R
If the vehicle occupants respond, the
Mercedes-Benz Customer Assistance Center
attempts to get more information on the
emergency. R
If there is no response from the vehicle occu-
pants, an ambulance is immediately sent to
the vehicle.
If no voice connection can be established to the
Mercedes-Benz Customer Assistance Center,
the system has been unable to initiate an emer-
gency call.
This can occur, for example, if the relevant
mobile phone network is not available. The indi-
cator lamp in the SOS button flashes continu-
ously.
