control system and COMAND operation,
refer to the Operator’s Manual.
The current operating mode of the HYBRID
system can be displayed in the multifunction
display and in the COMAND.
The COMAND can also display a chart of the
fuel consumption and the electric power that
has been generated ( Y page 15). Controls in detail

Recuperation – the hybrid transmission functions as a generator, for example when
coasting or braking. The kinetic energy of the vehicle is converted into electric power and
stored in the high-voltage battery.
The multifunction display indicates charging of the high-voltage battery by an arrow pointing
upwards. The pointer of the power gauge moves into the charge section. The COMAND
display indicates the flow of energy by green arrows.14

Electric driving
– the hybrid transmission powers the vehicle, up to a maximum speed of
30 mph (50 km/h).
The multifunction display indicates discharging of the high-voltage battery by an arrow
pointing downwards. The pointer of the power gauge moves within the range of its economy
section. The COMAND display indicates the flow of energy by green arrows. i
Maximum Hybrid battery life is ensured by
the electronic charge control maintaining a
charge level between 25 % and 80 %. This
is the ideal range for the Hybrid battery and
therefore the charge level displayed in the
instrument cluster or COMAND may not
approach 100 %. This is intentional and
does not indicate a malfunction of the
Hybrid battery or the charging
components. Displaying fuel consumption and

Safety notes
G
Warning!
When your vehicle is in electric drive mode the
engine produces significantly lower noise
levels. Other motorists or pedestriants,
especially those who are visually or hearing
impaired, may be unable to hear your vehicle
while it is in motion. This is particularly true
when driving at lower speeds and during
parking maneuvers. At all times, it is the
responsibility of the driver to be aware of their
surroundings, especially in these low speed
situtations. Otherwise other road users could
be seriously or fatally injured. G
Warning!
Make sure absolutely no objects are
obstructing the pedals’ range of movement. Keep the driver’s footwell clear of all
obstacles. If there are any floormats or
carpets in the footwell, make sure the pedals
still have sufficient clearance.
During sudden driving or braking maneuvers
the objects could get caught between or
under the pedals. You could then no longer
brake or accelerate. This could lead to
accidents and injury.
Starting the engine
:
READY indicator
X Switch on the ignition.
X Apply the brake pedal fully and release it.
The self-test of the RBS is completed. For
more information on the RBS, see
(Y page 9).
X Observe the notes on “Starting the engine”
in the Operator’s Manual and start the
combustion engine.
Silent-Start mode
The combustion engine may not start each
time you start the vehicle with the SmartKey
or with KEYLESS-GO.
Depending on various conditions such as the
charging level of the high-voltage battery, you
may drive off with electrical energy alone. The
vehicle is then in Silent-Start mode. The
READY indicator : will then indicate that the
HYBRID systems are operational. 16

Warning!
When the READY indicator in the instrument
cluster is on while the combustion engine is
off, the combustion engine has been turned
off automatically. All vehicle systems
continue
to be active as long as the ignition is
switched on. When you open the driver’s door
and unbuckle the seat belt with the READY
indicator on, while the automatic
transmission is in position N or P, the
combustion engine starts automatically.
Therefore, always do the following before
leaving the vehicle:
R Engage the parking brake.
R Shift the automatic transmission into park
position P.
R Switch off the ignition. The READY indicator
goes out.
The combustion engine turns off
automatically when the system determines
that it is not needed. The combustion engine
does not turn off automatically when
R the operation strategy requires that the
combustion engine is running
R the self-diagnosis of the combustion
engine management is still running
R the combustion engine is running below or
above the operating temperature
R the catalytic converter is running below the
operating temperature
R the vehicle is being driven up an extremely
steep incline
R the hybrid components are below or above
their operating temperature
R the accelerator pedal is being depressed to

Refueling
G
Warning!
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
personal injury.
Never allow sparks, flames or smoking
materials near gasoline!
Turn off the engine before refueling.
Whenever you are around gasoline, avoid
inhaling fumes and any skin or clothing
contact. Extinguish all smoking materials.
Direct skin contact with fuels and the
inhalation of fuel vapors are damaging your
health. G
Warning!
Overfilling of the fuel tank may create
pressure in the system which could cause a
gas discharge. This could cause the gas to
spray back out when removing the fuel pump
nozzle, which could cause personal injury.
! Never refuel vehicles with gasoline engine
with diesel fuel. Even small amounts of
diesel fuel will damage the fuel system and
engine. Damage resulting from the use of
non-approved fuels or fuel additives or
resulting from mixing gasoline with diesel
fuel is not covered by the Mercedes-Benz
Limited Warranty.
! If you have accidentally filled the tank
with incorrect or non-approved fuel, do not
switch on the ignition. Otherwise the
incorrect or non-approved fuel will get into
the fuel lines. The fuel system must be
drained completely. Contact an authorized
Mercedes-Benz Center to have the fuel
system drained completely.
! To prevent damage to the catalytic
converters, only use premium unleaded
gasoline in this vehicle.
Any noticeable irregularities in engine
operation should be repaired promptly. Otherwise, excessive unburned fuel may
reach the catalytic converter, causing it to
overheat and potentially start a fire.
i Only use premium unleaded gasoline with
a minimum Posted Octane Rating of 91
(average of 96 RON/86 MON).
Information on gasoline quality can
normally be found on the fuel pump. Please
contact gas station personnel in case
labels on the pump cannot be found.
For more information on gasoline, see
Operator's Manual, contact an authorized
Mercedes-Benz Center, or visit
www.mbusa.com (USA only).
X Bring the vehicle to a standstill.
X Engage the parking brake.
X Shift the automatic transmission into park
