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.
G DANGER
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. Introduction 7

If possible, move the vehicle out of the
danger zone: shift the automatic transmis-
sion into position N .X
Release the electric parking brake. X
Roll 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. X
Switch the ignition off. X

High-voltage battery
G WARNING
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.
G WARNING
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.

In the vehicle Operator's Manual, information and recommendations can be found on: R
using automatic climate control R
using the rear control panel R
the individual functions
Observe these notes for optimal use of the automatic climate control.
The "Cooling with air dehumidification" function is even available when the engine is not running
( Y
page 17).
Use the residual heat function if you want to heat or ventilate the vehicle interior when the ignition
is switched off. The residual heat function can only be activated or deactivated with the ignition
switched off. When the ignition is switched on, the residual heat function is switched off
( Y
page 17).
Operating the climate control sys-
tems
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. X
To activate: press the Z or V button.
The indicator lamp in the Z or V button
lights up. X
To deactivate: press the Z or V but-
ton.
The indicator lamp in the Z or V button
goes out. The "Cooling with air dehumidifica-
tion" function has a delayed switch-off fea-
ture.
Switching the residual heat on or off
It is possible to make use of the residual heat of
the engine to continue heating the stationary
vehicle for up to 30 minutesafter the engine has
been switched off. The heating time depends on
the set interior temperature. X
To activate: press the K or V button.
The indicator lamp in the K or V button
lights up. X
To deactivate: press the K or V but-
ton.
The indicator lamp in the K or V button
goes out.
The blower will run at a low speed regardless of
the airflow setting.
If you activate the residual heat function at high
temperatures, only the ventilation will be acti-
vated. The blower runs at medium speed.
Residual heat is deactivated automatically: R
after approximately 30 minutes R
when the ignition is switched on R
if the battery voltage drops
Pre-entry climate control via Smart-
Key
General notes Before getting in, the vehicle interior can be
briefly warmed or ventilated in advance and the
air from the air vents can be pre-cooled.
The high-voltage battery must be sufficiently
charged before "Pre-entry climate control via
SmartKey" can be activated.
When the vehicle is pre-cooled, the following
functions are activated if required: R
Climate control system R
Blower R
Seat ventilationOperating the climate control systems 17
Climate control

If manual gearshifting is deactivated, the auto-
matic transmission shifts: R
into the drive program that was last selected,
and R
into 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.

ECO start/stop function
General notes
The ECO start/stop function swit ches the com-
bustion engine off automatically when the veh i-
cle stops moving and at spee ds below 80 mph
(13 0 km/ h) ( Y
page 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
shifting.
Automatic engine switch-off The engine is switched off automatically, includ-
ing when: R
the driver removes his/her foot from the
accelerator in the Comfort drive program and
a speed of 80 mph (130 km/h) is not excee-
ded ( Y
page 24) R
the engine has reached its operating temper-
ature R
the driver’s seat belt is fastened and the
driver’s door is closed R
the driver only slightly depresses the accel-
erator pedal in order to, for example, maintain
the current speed for a limited distance R
the hood is closed and engaged properly R
the high-voltage battery is charged suffi-
ciently R
no malfunctions are present in the hybrid
drive system
The internal combustion engine will not be
switched off automatically, if: R
the self-diagnosis function of the engine man-
agement is active R
there is a malfunction in the hybrid drive sys-
tem R
the climate control of the vehicle requires it R
the high-voltage battery is charging
( Y
page 40).
Automatic engine start The automatically switched-off internal combus-
tion engine starts automatically in certain situa-
tions, if: R
the power demand from the driver via the
accelerator pedal is greater than the electric
motor alone can provide R
the driver switches to the Sport drive pro-
gram or to manual gearshifting R
the condition of charge of the high-voltage
battery has reached the lower limit R
the driver has selected the CHARGE operating
mode Driving 23
Driving and parking

Overrun mode In overrun mode, the combustion engine is
switched off and is disconnected from the drive
train. The electric motor: R
generates low thrust, which corresponds to
the overrun mode of an active combustion
engine R
functions as a generator and produces the
necessary energy for the auxiliary consumers
and charges the high-voltage battery
Overrun mode is available in the Comfort drive
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: R
road categories R
speed 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: R
the sections of the journey ahead R
the 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: R
the fuel saving through the use of electrical
energy can vary, dependent on the route (e.g.
urban, interurban or highway) R
the 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: R
the Individual drive program is selected R
in the Individual drive program, the ECO set-
ting is selected under Drive R
HYBRID driving mode is selected R
active route guidance is activated R
suitable 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.24

Hybrid drive system Problem
Possible causes/consequences and P Solutions
The hybrid drive system
has been switched off
automatically. You have been in an accident.
The hybrid drive system remains switched off if: R
the internal combustion engine cannot be restarted after a few
seconds. R
the red u restraint system warning lamp in the instrument clus-
ter is lit. X
Consult a qualified specialist workshop.
The hybrid drive system
has been switched off
automatically. The multi-
function display also
shows a display mes-
sage. An electrical short circuit has occurred in the hybrid drive system or an
electrical connection has been disconnected. X

play (see the vehicle Operator's Manual). X
Consult a qualified specialist workshop.
Driving tips
General driving tips Drive carefully and maintain a safe distance
from the vehicle in front. Avoid frequent and
sudden acceleration as well as abrupt braking.
During partial electric driving, pulling away and
acceleration, the electric motor supports the
internal combustion engine.
During overrun in transmission position D and
braking, the electric motor will operate as a gen-
erator.
Further information on the ECO start/stop func-
tion ( Y
page 23).
You can find further driving tips in the vehicle
Operator's Manual.
Stationary vehicle If the vehicle is stopped, the combustion engine
is, for the most part, switched off. Automatic
climate control continues to function. The elec-
tromechanically assisted steering gear allows
you to use the power steering without reduced
comfort. Acceleration Depending on the operating mode, pulling away
and driving under low load conditions are per-
formed: R
entirely by electric propulsion R
in combination with the internal combustion
engine
When accelerating rapidly under increased or
full load, increased boost mode is utilized. The
electric motor supports the combustion engine
by providing additional drive torque.
Overrun mode or braking There are three possible operating modes when
the hybrid vehicle is decelerating: R
energy recovery takes place even when the
vehicle is decelerating purely in overrun mode
( Y
page 20). The electric motor operates as a
generator and stores the recovered energy in
the high-voltage battery R
when the brakes are applied lightly, the vehi-
cle is slowed down further by the electric
motor. This increases the energy recovery
taking place ( Y
page 20). The electric motor
operates as a generator and stores the recov-
ered energy in the high-voltage battery R
during heavy braking, the service brake is also
used to slow down the vehicle. The two sys-
tems work together26
