Enviromental protection
Have the high-voltage battery disposed of in
an environment-friendly manner by an
authorized Mercedes-Benz Center. G
Warning!
The HYBRID system is energized by high
voltage. The components of the HYBRID
system are indicated by yellow warning
labels. High-voltage cables are orange-
colored.
You could be seriously or even fatally injured
when you
R tamper with components or high-voltage
cables of the HYBRID system
R touch components or high-voltage cables
of
the HYBRID system after the vehicle has
been involved in an accident
R touch damaged components of the HYBRID
system
Do not remove the high-voltage battery of the
HYBRID system. Have the high-voltage
battery disposed of in an environment-
friendly manner by an authorized Mercedes-
Benz Center. Operating safety
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!
Have all work on the vehicle, especially safety-
related work, work on safety-relevant
systems,

work on the HYBRID system as well
as maintenance work, carried out by an
authorized Mercedes-Benz Center.
i For more information on operating safety,
refer to the Operator’s Manual. Vehicle modifications
G
Warning!
Improper work on the HYBRID system or
modifications
of the vehicle can cause vehicle
systems to cease functioning properly. You
could lose control over the vehicle and cause
an accident.
Therefore, have work on the HYBRID system
and modifications of the vehicle such as
installation or modification of vehicle
equipment carried out by an authorized
Mercedes-Benz Center
i For more information on operating safety,
refer to the Operator’s Manual. Proper use of the vehicle
Proper
use of the vehicle requires that you are

Safety notes
Warning labels
G
Warning!
Various warning labels are attached to your
vehicle. These warning labels are intended to
make you and others aware of various risks.
Do not remove any of these warning labels
unless explicitly instructed to do so by
information on the label itself. Removing
warning labels may cause you and others to
be unaware of certain risks which may result
in an accident and/or personal injury.
Danger of electric shock The components of the HYBRID system are
indicated by yellow warning labels to make
you aware of high voltage. High-voltage
cables are orange-colored.
G
Warning!
The HYBRID system is energized by high
voltage.
You could be seriously or even fatally injured
when you
R tamper with components or high-voltage
cables of the HYBRID system
R touch components or high-voltage cables
of the HYBRID system after the vehicle has
been involved in an accident
R touch damaged components of the HYBRID
system
Do not remove covers of components of the
HYBRID system that carry the yellow warning label. Do not tamper with any components or
with the orange high-voltage cables of the
HYBRID system.
Engine compartment
Before opening the hood do the following:
X Engage the parking brake.
X Shift the automatic transmission into park
position P.
X Switch off the ignition.
The READY indicator (Y page 16) in the
instrument cluster goes out.
X Remove the SmartKey from the starter
switch or remove the SmartKey with
KEYLESS-GO from the vehicle.
X Observe the safety notes on the danger of
electric shock in this manual.
X Observe the safety notes regarding the
hood in the Operator’s Manual. Automatic HYBRID system switch-off
The HYBRID system switches off
automatically if
R the Supplemental Restraint System (SRS)
activates the restraint systems in an
accident
R a short circuit in the HYBRID system is
detected
R a plug connection of the HYBRID system is
disconnected
These measures help to prevent you from
coming into contact with high voltage. High-voltage battery

Warning!
The high-voltage battery of the HYBRID
system is located under the cargo
compartment. When the pressure inside the
high-voltage battery exceeds a certain value, 8

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
