Important safety notes
G WARNING
If persons, particularly children are subjected
to prolonged exposure to extreme heat or
cold, there is a risk of injury, possibly even
fatal. Never leave children unattended in the
vehicle. General notes You can use the "Pre-entry climate control at
departure time" function to cool or heat the
vehicle interior if the engine is not running.
The "Pre-entry climate control at departure
time" function can be activated regardless of
whether or not the vehicle is connected to an
electric power supply. The condition of charge of
the high-voltage battery must be higher than the
specified minimum condition of charge, how-
ever.
When the vehicle is connected to an electric
power supply, priority is given to charging the
high-voltage battery to the specified minimum
charge. "Pre-entry climate control at departure
time" is only activated subsequently.18

Points to remember
General notes Hybrid technolog y combine s a fue l efficien t
internal combustion engin e wit h a powerful
electric motor. In HYBRID mode, th e hybrid
drive syste m automatically selects th e most effi-
cien t operatin g mode fo r every drivin g situation .
Drive th e vehicle in th e usual manner.
To sav e fue l in HYBRID mode, th e hybrid drive
syste m switches of f th e combustion engin e as
ofte n as possible durin g th e journey when powe r
output requirements are low. Whe n powe r out -
put requirements are low, th e electric moto r
powers th e vehicle. The engin e is switched on ,
eve n whil e th e vehicle is in motion , when a
higher powe r output is required. The engin e is
usually switched of f when th e vehicle is station -
ary. Consequently, there is usually no engin e
idlin g as wit h combustion engin e vehicles .
Fo r pulling away and accelerating, th e electric
moto r supports th e internal combustion engin e
usin g th e powe r stored in th e high-voltage bat -
tery. In addition , th e powe r is used fo r electric
driving, operation of th e electric refrigerant
compressor and to supply th e 12 V on-boar d
electrical system. In this way th e hybrid drive
s y ste m helps to reduce your vehicle' s fue l con-
sumption .

Recuperative Brak e Syste mIf you release th e accelerator peda l when th e
vehicle is in motion , overrun recuperation is ini-
tiated. The electric moto r is operated as a gen -
erato r when in overrun mode and when you
brake . Hybrid technolog y convert s th e kineti c
energ y of th e vehicle into electricit y and stores
it in th e high-voltage battery.

Vehicles wit h an electric moto r generate muc h
les s drivin g noise than vehicles wit h internal
combustion engines. As a result , your vehicle
may no t be hear d by other road user s in certain
situations.
Dependin g on th e vehicle' s equipmen t and
country-specific regulations, th e vehicle can be
equipped wit h Acoustic Vehicle Indication .
Acoustic Vehicle Indication generate s a certain
soun d at a speed between 0 and 20 mph
(30 km/h). Thi s helps other road users, par tic-
u l arly pedestrian s and cyclists, to hear your
vehicle better. The soun d can also be hear d
insid e th e vehicle.
The volume depend s on th e engin e speed. The
faste r you accelerate, th e louder th e soun d is. At
a speed of over 20 mph (30 km/ h) the sound is
switched off. Above this speed, the natural
sounds from the vehicle are sufficient that it can
be heard in good time by other road users.20
Driving
Dr ivi ng an d parking

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.

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

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
Driving tips
Driving and parking

Urban driving In city traffic, energy is recuperated during fre-
quent deceleration phases.
The vehicle can be driven by the electric motor
alone up to a speed of approximately 80 mph
(130 km/h).
The vehicle is driven by the electric motor alone
only when all conditions for the automatic
engine switch-off are fulfilled.
Further information on the automatic engine
switch-off ( Y
page 23).
Driving on inter-urban roads The following phases are possible when driving
on inter-urban roads: R
rapid acceleration (boost mode) R
energy recuperation R
electric operation mode
The vehicle can be driven by the electric motor
alone up to a speed of approximately 74 mph
(120 km/ h) .
A great deal of recovered energy may be avail-
able, depending on the route profile. This
reduces consumption and emissions.
Highway driving When driving on a highway, switching off the
combustion engine has a particularly positive
effect on fuel consumption and emissions.
If the driver removes his/her foot from the
accelerator pedal in the Comfort drive program
and a speed of 80 mph (130 km/h) is not excee-
ded, the combustion engine is automatically
switched off.
Further information on the automatic engine
switch-off ( Y
page 23).
Refueling
Refueling
General information
Observe the important safety notes under
"Refueling" in the vehicle Operator's Manual. Pressure in the fuel tank must be released
before refueling. Otherwise, the fuel filler flap
cannot be opened.
If you unlock/lock the vehicle from the outside,
the fuel filler flap also unlocks/locks.
The position of the fuel filler cap is displayed in
the instrument cluster

R
Never touch damaged components or the
damaged orange cables of the high-voltage
electrical system. R
Do not remove the covers of the high-voltage
electrical system components that are
marked with a warning sticker.
General notes
Method of operation The vehicle is equipped with a high-voltage bat-
tery for driving. The high-voltage battery stores
the energy needed to operate the electric motor
and releases it again.
The electric motor uses energy that has been
stored in the high-voltage battery when pulling
away, accelerating and during the journey.
In overrun mode, kinetic energy is converted by
means of energy recuperation into electrical
energy and stored in the high-voltage battery.
Information on overrun mode ( Y
page 24).
The high-voltage battery can be charged as fol-
lows: R
through energy recuperation while the vehicle
is in motion R
through the combustion engine while driving
in CHARGE operating mode ( Y
page 21)R
with the relevant charging cable at an electri-
cal outlet while the vehicle is stationary R
at a wallbox while the vehicle is stationary R
at a charging station while the vehicle is sta-
tionary
The high-voltage battery can be charged in a
nominal voltage range from 100 V to 240 V.
You can view the condition of charge of the high-
voltage battery in the multifunction display.
Information about this can be found under
"Energy flow display" ( Y
page 40).
High and low outside temperatures Low outside temperatures
At very low outside temperatures the maximum
power output of the high-voltage battery may be
reduced. The high-voltage battery is then no
longer able to provide the normal electrical
power output.
High outside temperatures
To prevent damage to the high-voltage battery
due to very high outside temperatures, the max- imum power output of the high-voltage battery
is reduced by the vehicle.
Energy consumption and electrical
range The maximum electrical range is generally
reduced by: R
high and low outside temperatures R
operating the climate control system R
switching on consumers
The battery's physical characteristics are such
that leaving the vehicle parked for long periods
at low outdoor temperatures without charging it
can lead to: R
a reduction in battery performance R
longer charge times
Notes on battery care Avoid storing or transporting the vehicle at
excessively high or low temperatures over a long
period.
If you park the vehicle and leave it stationary for
long periods: R
check the condition of charge of the high-
voltage battery more often R
connect the vehicle to a power supply
This prevents self-discharge and damage to the
high-voltage battery.
Terms of use Please note the information on exceptions and
limitations in warranty documentation and in
the Maintenance Booklet.
Handling the charging cable and charg-
ing cable controls Always read the notes on the charging cable on
the inside of the charge socket flap.
Do not leave the charging cable controls
( Y
page 32) hanging loose from an electrical
outlet. Otherwise, this could result in a poor
contact with the electrical outlet and malfunc-
tions when charging the vehicle.30
