Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.

Warning sticker
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
marked with yellow warning stickers that
warn you of high voltage. The electrical wires
for the vehicle's high-voltage electrical
system are orange in color. G
WARNING
The hybrid system operates at high voltage.
You could be seriously or even fatally injured
if you:
R tamper with components or the high-
voltage cables of the hybrid system
R touch components or high-voltage cables
in the hybrid system of a vehicle which has
been involved in an accident
R touch damaged components of the hybrid
system
Do not remove the hybrid system component
covers that are marked with warning stickers.
Do not tamper with components or the orange
high-voltage cables of the hybrid system. Engine compartment
Before opening the hood:
X Apply the parking brake and use the
DIRECT SELECT lever to shift the
transmission to P.
X Switch the ignition off.
The green or yellow READ Yindicator
(Y page 21) in the instrument cluster
goes out.
X Remove the SmartKey from the ignition or
remove the KEYLESS GO key from the
vehicle.
X Observe the warning notes in this
supplement on the ris kofelectric shock.
X Observe the warning notices about the
hood (see vehicle Operator's Manual). 14
Important safety notesSafety

Automatic deactivation of the hybrid
system
The hybrid system is deactivated
automatically if:
R SRS (Supplemental Restrain tSystem)
activates the restraint system in an
accident
R a short circui tis detected in the hybrid
system.
R one of the hybrid system’s electrical
connections is disconnected.
This ensures that you do not come into
contact with high voltage. High-voltage battery
G
WARNING
The high-voltage battery in the hybrid system
is located on the front bulkhead in the engine
compartment on the right-hand side when
viewed in the direction of travel. If, e. g. in the
event of a vehicle fire, the internal pressure of
the high-voltage battery exceeds a certain
value, flammable gas escapes through a line
in the area of the right front wheel. This
prevents the high-voltage battery from
exploding.
Leave the danger area. If necessary, set up
the warning triangle at asuitable distance.
Observe legal requirements. Driving safety systems
ABS (Anti-lock Braking System)
Braking If ABS intervenes when braking, the yellow
÷ ESP®
indicator lamp flashes in the
instrument cluster (Y page 35). You only
feel the brake pedal pulsating in certain
situations, e.g .onslippery roads.
i Further information about ABS; (see
vehicle Operator's Manual). RBS (Recuperative Brake System)
RBS supports you when braking with an
electronically-controlled brake boost mode
and enables the recovery of kinetic energy. G
WARNING
Always have work on the RBS system, e.g.
replacemen tofbrake pads, carried out at a
qualified specialist workshop.
Certain points must be taken into account
when carrying out work on the RBS system,
e.g. for system restart.
Mercedes-Benz recommends that you use an
authorized Mercedes-Benz Center for this
purpose. In particular, work relevant to safety
or on safety-related systems must be carried
out at a qualified specialist workshop. G
WARNING
If RBS malfunctions, braking resistance may
be reduced and brake pedal travel may be
longer than usual. The brake system is still
fully functional .Ifnecessary, depress the
brake pedal further. Adjust your driving style
and vehicle speed accordingly.
i The first time the brake pedal is
depressed after switching on the engine,
braking resistance may be reduced and
brake pedal travel may be greater than
usual. When you release the brake pedal,
pedal travel then returns to normal.
Remember the following points about RBS
(Y page 20).
The yellow éRBS warning lamp and/or
the red $brake warning lamp light up in
the instrument cluster if RBS is
malfunctioning. Follow the instructions in the
multifunction display (Y page 31).

WARNING
When the vehicle is stationary and the green
READY indicator in the instrument cluster is
lit, this means that the engine has been
switched off automatically. All of the vehicle's
systems remain active.
If you remove your foot from the brake pedal
while in transmission position DorR, the
vehicle may pull away automatically.
There is a risk of an accident.
Exit the vehicle only if:
R both the green and yellow READY
indicators in the instrument cluster are off
R you have secured the vehicle to preven tit
from rolling away.
The hybrid syste mcombines a fuel efficient
internal combustion engine with a powerful
electric motor. The hybrid system
automatically selects the most efficient
operating mode for every driving situation.
Drive the vehicle in the usual manner.
In order to save fuel, the hybrid system
switches the engine off as often as possible,
whenever less power output is required as
you drive. The electric motor provides the
propulsion. The engine is switched on, even
while the vehicle is in motion, when a higher
power output is required. The engine is usually switched off when the vehicle is
stationary. The typical idling of conventional
engines is therefore generally absent.
For the high-consumption tasks of pulling
away and accelerating, the electric motor
assists the internal combustion engine using
the stored energy from the high-voltage
battery. This energy is also used for driving in
partially electric mode (Y
page 25), to
operate the electric refrigerant compressor
and support the 12V on-board electrical
system. In this manner, the hybrid drive
makes a crucial contribution to fuel
conservation.
Notes on driving and parking (Y page 21).
You can display the hybrid system's current
operating mode in the multifunction display
and the COMAND display (Y page 28).
In the COMAND display, you can also call up
a graphic display of the fuel consumption and
generated electricity (Y page 31). RBS
RBS (Y page 15) uses the electric motor as a
generator in overrun mode (Y page 23) and
when braking. The hybrid system converts
the kinetic energy of the vehicle into
electricity and stores it in the high-voltage
battery. It is unnecessary to additionally
charge the high-voltage battery via an
external power system. 20
Points to rememberDriving and parking

X
Switch on the ignition.
X Start the vehicle.
READY indicator :lights up in the
multifunction display .The vehicle is ready
to drive.
X Depress the brake pedal and select a gear.
i The first time the brake pedal is
depressed, braking resistance is reduced
and brake pedal travel is greater than usual.
Noiseless start
When you start the vehicle, electric operation
mode can be used. The engine starts up when
the power required by the driver exceeds the
power currently available from the electric
motor.
Noiseless start is dependent on the outside
temperature and the operating temperature
of the hybrid system.
If the hybrid system has been started using
noiseless start, green READY indicator :
lights up in the multifunction display.
Pulling away If you are depressing the brake pedal when
shifting the transmission from
Pto Dor Rand
still see the Apply Brake to Shift from 'P' display message in the multifunction
display:
X Depress the brake pedal more firmly and
select the desired transmission position.

temperature
R the driver’s seat belt is fastened and the
driver’s door is closed
R the driver only slightly depresses the
accelerator pedal
R the hood is closed and engaged properly 22

WARNING
Vehicles with an electric motor generate
much less driving noise than vehicles with
internal combustion engines. As a result, your
vehicle may not be heard by other road users
in certain situations, for example when
parking or when your vehicle has not been
seen by other road users.
This requires you to adopt aparticularly
anticipatory driving style, as it is necessary to
allow for the possibility that other road users
may behave erratically. G

When the vehicle is stationary and the green
READY indicator in the instrument cluster is
