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 320).
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. The Call Failed message appears in the mul-
tifunction display and must be confirmed.
In this case, summon assistance by other
means.

Important safety notes
G WARNING
If the hood is unlatched, it may open up when
the vehicle is in motion and block your view.
There is a risk of an accident.
Never unlatch the hood while driving. Before
every trip, ensure that the hood is locked.
G WARNING
When opening and closing the hood, it may
suddenly fall into the closed position. There is
a risk of injury to persons within range of
movement of the hood.
Open and close the hood only when no one is
within its range of movement.
G WARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
G WARNING
The engine compartment contains moving
components. Certain components, such as
the radiator fan, may continue to run or start
again suddenly when the ignition is off. There
is a risk of injury.
If you need to do any work inside the engine
compartment: R
switch off the ignition R
never reach into the area where there is a
risk of danger from moving components,
such as the fan rotation area R
remove jewelry and watches R
keep items of clothing and hair, for exam-
ple, away from moving parts
G WARNING
The ignition system and the fuel injection sys-
tem work under high voltage. If you touch
components which are under voltage, you
could get an electric shock. There is a risk of
injury.
Never touch components of the ignition sys-
tem or fuel injection system when the ignition
is switched on.
Opening the hood
G WARNING
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 compartment poses a
risk of injury.
Where possible, let the engine cool down and
touch only the components described in the
following.

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
in a different location.
When checking the oil level: R
park the vehicle on a level surface. R
the engine should be switched off for approx-
imately five minutes if the engine is at normal
operating temperature. R
all vehicles (except Mercedes-AMG C 63/C
63S): 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.

to the tires or chassis components. Compo-
nents damaged in this way may fail unexpect-
edly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced imme-
diately.
