Protecting the environment
HEnvironmental note
Have a defective high-voltage battery dis-
posed of in an environmentally-responsible
manner. Contact a qualified specialist work-
shop which has the necessary specialist
knowledge and tools to carry out the work
required. Mercedes-Benz recommends that
you use an authorized Mercedes-Benz Center
for this purpose.
Operator's Manual
Vehicle equipment
This Supplement provides information on all the
important functions of your hybrid vehicle that
are either not described or differ from the
descriptions in the vehicle's Operator's Manual. The information supplements or substitutes the
corresponding sections in the vehicle's Opera-
tor's Manual. Under no circumstances does the
supplement replace the Operator's Manual.
This Supplement describes all models, and
standard and optional equipment for your sys-
tem, as available at the time of going to print.
Country-specific differences are possible. Bear
in mind that your vehicle may not feature all
functions described here. This also applies to
safety-relevant systems and functions. The
equipment in your vehicle may therefore differ
from that shown in the descriptions and illus-
trations.
The original purchase contract documentation
for your vehicle contains a list of all the systems
in your vehicle.
Should you have any questions concerning
equipment and operation, please consult an
authorized Mercedes-Benz Center.
The Operator's Manual and Maintenance Book-
let are important documents and should be kept
in the vehicle.
Operating safety
Important safety notes
Hybrid vehicles have a combustion engine and
an electric motor. The voltage supply for oper- ating the vehicle electrically is provided by the
vehicle's high-voltage electrical system on the
hybrid drive system.
GDANGER
The vehicle's high-voltage electrical system is under high voltage. If you modify components
in the vehicle's high-voltage electrical system
or touch damaged components, you may be
electrocuted. The components in the vehi-
cle's high-voltage electrical system may be
damaged in an accident, although the damage
is not visible. There is a risk of fatal injury.
Following an accident, do not touch any high-
voltage components and never modify the
vehicle's high-voltage electrical system. Have
the vehicle towed away after an accident and
the vehicle's high-voltage electrical system
checked by a qualified specialist workshop.
All components of the hybrid drive system are
marked with yellow warning stickers that warn
you of the danger of high voltage. The cables of
the vehicle's high-voltage electrical system are
orange in color.
Always have all work on the hybrid drive system
carried out at a qualified specialist workshop.
An authorized Mercedes-Benz Center is a quali-
fied specialist workshop.
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. This can happen, for example, when
you are parking and your vehicle is not seen by
other road users. This requires you to adopt a
particularly anticipatory driving style, as it is
necessary to allow for the possibility that other
road users may behave erratically.
Introduction7
Z

XIf possible, move the vehicle out of the
danger zone:shift the automatic transmis-
sion into position N.
XRelease the electric parking brake.
XRoll the vehicle to a safe place and park it
safely.
Get assistance from others if necessary.
The vehicle is locked automatically when the
ignition is switched on and the wheels are turn-
ing. There is therefore a risk of being locked out
if the vehicle is being pushed or tested on a
dynamometer.
XSwitch the ignition off.
XShift the automatic transmission to park posi-
tion P.
Apply the electric parking brake.
Safeguard the vehicle against rolling away
(see the vehicle Operator's Manual).
XTo use the high-voltage switch-off device:
open the tailgate.
XLift the cargo compartment floor upwards
(see the vehicle Operator's Manual).
XPull off the right-hand paneling in the cargo
compartment.
XPress release clip :in the direction of the
arrow and pull it out.
XPull high-voltage switch-off device ;apart
until it engages.
If the hybrid drive system has been deactivated
due to reasons mentioned above, have it
checked at a qualified specialist workshop
before reactivation.
High-voltage battery
GWARNING
In the event of a vehicle fire, the internal pres- sure of the high-voltage battery can exceed a
critical value. In this case flammable gas
escapes through a ventilation valve on the
underbody. The gas can ignite. There is a risk
of injury.
Leave the danger zone immediately. Secure
the danger area at a suitable distance, whilst
observing legal requirements.
GWARNING
If the housing of the high-voltage battery has
been damaged, electrolyte and gases may
leak out. These are poisonous and caustic.
There is a risk of injury.
Avoid contact with skin, eyes or clothing.
Immediately rinse electrolyte splashes off
with water and seek medical attention
straight away.
!Exhaustive discharge caused by the vehicle
standing idle for lengthy periods can damage
the high-voltage battery. If the vehicle is idle
for lengthy periods leave the high-voltage bat-
tery connected to a charging station.
Charging the high-voltage battery (
Ypage 29).
Engine compartment
Before opening the hood:
XApply the electric parking brake.
XShift the transmission to position P.
XSwitch the ignition off.
XObserve the warning notes on the risk of elec-
tric shock (Ypage 10).
XObserve the warning notes on the hood (see
the vehicle Operator's Manual).
RBS driving safety system (Recupera-
tive Brake System)
The Recuperative Brake System supports you
when braking with an electronically-controlled
brake boost mode and enables the recovery of

Overview of climate control systems
General notes
Observe the notes and the recommended settings in the vehicle Operator's Manual. The windowscould otherwise fog up.
Climate control regulates the temperature and air humidity in the vehicle interior. Due to the elec-
trical refrigerant compressor, the "Cooling with dehumidification" function is also operational with-out the combustion engine running. Optimum climate control is only achieved with the side windows
and roof closed.
The residual heat function can only be activated or deactivated with the ignition switched off
(
Ypage 17).
The "Pre-entry climate control" function is available. Use this function to briefly preheat or ventilate
the driver's seat area or the entire vehicle interior before entering the vehicle. The air from the air
vents can also be pre-cooled.

Switching cooling with air dehumidi-
fication on/off
If you deactivate the "Cooling with air-dehumid-ification" function, the air inside the vehicle will
not be cooled. The air inside the vehicle will also
not be dehumidified. The windows can fog up
more quickly. Therefore, deactivate the cooling
with air-dehumidification function only briefly.
The "Cooling with air dehumidification" function
is available even when the engine is not running.
The air inside the vehicle is cooled and dehu-
midified according to the temperature selected.
Condensation may drip from the underside of
the vehicle when it is in cooling mode. This is
normal and not a sign that there is a malfunc-
tion.
XTo activate: press the¿orÁ button.

Dr iving an d parking

If manual gearshifting is deactivated, the auto-
matic transmission shifts:
Rinto the drive program that was last selected,
and
Rinto the driving mode that was last selected
If you change the drive program, the operating
mode that was last selected is stored for approx-
imately 60 seconds. After this time, the HYBRID
operating mode is automatically activated.
Starting the engine
The vehicle starts in electric mode without the
internal combustion engine (noiseless start).
The internal combustion engine starts only after the power demanded by the driver exceeds the
available power that the electric motor can cur-
rently provide.
Noiseless start operation is dependent on the
outside temperature and the operating temper- ature of the internal combustion engine. If not all
conditions for noiseless start operation are ful-
filled, the vehicle starts with the internal com-
bustion engine.
Observe the notes on starting in the vehicle
Operator's Manual.
XSwitch on the ignition.
XDepress the brake pedal.
XStart the vehicle (see the vehicle Operator's
Manual).

General notes
The ECO start/stop function switches the com-
bustion engine off automatically when the veh i-
cle stops moving and at speeds below 80 mph
(13 0km/ h)(
Ypage 24). All vehicle systems remain active, e.g. the auto-
matic climate control.
The ECO start/stop function is neither available
in the
Sport drive program nor during manual

Automatic engine switch-off
The engine is switched off automatically, includ-
ing when:
Rthe driver removes his/her foot from the
accelerator in the Comfortdrive program and
a speed of 80 mph (130 km/h) is not excee-
ded (
Ypage 24)
Rthe engine has reached its operating temper- ature
Rthe driver’s seat belt is fastened and the
driver’s door is closed
Rthe driver only slightly depresses the accel-
erator pedal in order to, for example, maintain
the current speed for a limited distance
Rthe hood is closed and engaged properly
Rthe high-voltage battery is charged suffi-
ciently
Rno malfunctions are present in the hybrid
drive system
The internal combustion engine will not be
switched off automatically, if:
Rthe self-diagnosis function of the engine man-
agement is active
Rthere is a malfunction in the hybrid drive sys-
tem
Rthe climate control of the vehicle requires it
Rthe high-voltage battery is charging

Automatic engine start
The automatically switched-off internal combus-
tion engine starts automatically in certain situa-
tions, if:
Rthe power demand from the driver via the
accelerator pedal is greater than the electric
motor alone can provide
Rthe driver switches to the Sportdrive pro-
gram or to manual gearshifting
Rthe condition of charge of the high-voltage
battery has reached the lower limit
Rthe driver has selected the CHARGE operating
mode

Driving and parking

Overrun mode
In overrun mode, the combustion engine is
switched off and is disconnected from the drive
train. The electric motor:
Rgenerates low thrust, which corresponds to
the overrun mode of an active combustion
engine
Rfunctions as a generator and produces the
necessary energy for the auxiliary consumersand charges the high-voltage battery
Overrun mode is available in the Comfortdrive
program at speeds below 80 mph (130 km/h).
Route-based operating strategy
For the route-based operating strategy, the sys-
tem factors in information about the expected
route when route guidance is active.
The information on the route is provided by the
multimedia system and includes the following:
Rroad categories
Rspeed limitations
The use of electric energy is automatically opti-
mally distributed from the beginning to the end
of the journey, using information about the
route. The distribution is pre-emptive and takes
into consideration:
Rthe sections of the journey ahead
Rthe energy consumption on the whole route The condition of charge of the high-voltage bat-
tery is thus systematically controlled. In addi-
tion, the control function takes into account
that:
Rthe fuel saving through the use of electrical
energy can vary, dependent on the route (e.g.
urban, interurban or highway)
Rthe use of electrical energy is held available
for electric driving, particularly for urban
routes
The vehicle thus automatically selects the opti-
mum driving mode for the respective section of
the route.
The route-based operating strategy is available
under the following conditions:
Rthe Individual drive program is selected
Rin theIndividual drive program, the ECO set-
ting is selected under Drive
RHYBRID driving mode is selected
Ractive route guidance is activated
Rsuitable map data is available
When the route-based operating strategy is
being used, the area in front of the vehicle is
shown as green in the multifunction display.
