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

Closing the hood
XLower the hood and let it fall from aheight of
approximately 8in(20 cm).
XCheck that the hood has engaged properly.
If the hood can be raised slightly, it is not
properly engaged. Open it again and close it
withalittle more force.
Radiator
Do not cover up the radiator, such as with a
thermal mat or insect protection cover. The
readings of the on-board-diagnostic system may
otherwise be inaccurate. Some of these read-
ings are required by law and must be accurate at
all times.
Engine oil
Important safety notes
GWARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartmentp oses a
risk of injury.
Where possible, let the engine cool down and touch only the components described in the
following.
GWARNING
If engine oil comes into contact with hot com- ponentsint he engine compartment, it may
ignite. There is arisk of fire and injury.
Make sure that engine oil is not spilled next to
the filler neck.L et the engine cool down and
thoroughly clean the engine oil off the com-
ponentsb efore startin gthe engine.
General notes
Depending on your driving style, the vehicle
consumes up to 0.9 US qt (0.8 liters) of oil per
600 miles (1,000 km). The oil consumption may
be higher than this when the vehicle is new or if
you frequently drive at high engine speeds.
Depending on the engine, the oil dipstick may be
inad ifferent location.
When checking the oil level:
Rpark the vehicle on alevel surface
Rthe engine should be switched off for approx-
imately five minutes if the engine is at normal
operating temperature
Rall vehicles (except Mercedes-AMG C63/C
63S): if the engine is not at normal operating
temperature, e.g. if the engine was only star-
ted briefly, wait approximately 30 minutes
before carrying out the measurement
The oil level of the Mercedes-AMG C63/C 63 S
must be checked only when the engine is at
normal operating temperature.
