Introduction
The HYBRID technology combines an
economical combustion engine with a
powerful hybrid transmission. The HYBRID
system selects the most efficient operating
mode
for each driving situation automatically.
You can drive the vehicle in the usual manner.
The HYBRID system turns the combustion
engine off as often as possible in order to save
fuel.
Depending on various conditions such as the
charging level of the high-voltage battery or
the operating temperature, the vehicle can
run on electrical energy alone. These
conditions as well as the degree to which the
driver accelerates determine the vehicle
speed and range that can be achieved for all-
electrical driving. G
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. Driving off and accelerating consumes the
most energy. Thus, the hybrid transmission
supports the combustion engine with the
energy

stored in the high-voltage battery. The
energy is also used for electrical driving, for
operation of the electric compressor of the
cooling system and to support the 12-volt on-
board power supply. The hybrid drive thereby
contributes significantly to the fuel economy
of your vehicle.
For information on driving with HYBRID, see
(Y page 16).
The current operating mode of the HYBRID
system can be displayed in the instrument
cluster (Y page 13) and in the COMAND
display ( Y page 13).
The COMAND can also display a chart of the
fuel consumption and the electric power that
has been generated ( Y page 15). RBS (Recuperative Brake System)
With
the RBS activated (Y page 9), the hybrid
transmission functions as a generator when
coasting and braking. HYBRID converts the
energy of movement into electric power and
stores it in the high-voltage battery. The high-
voltage battery does not require additional
charging by other means. Controls in detail

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
:

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!
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.
