Drivin g
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 .
Observ e th e drivin g tips on plug-i n hybrid oper-
ation ( Y
page 26).
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.
Observ e th e important safet y note s fo r th e
Recuperative Brak e Syste m ( Y
page 11) . Important safet y notesIf th e engin e is switched of f by th e EC O start /
stop function , you ope n th e driver's doo r and

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

Try to start the internal combustion engine again.
If the internal combustion engine still does not start: X
Consult a qualified specialist workshop.
You wish to pull away,
but the ECO start/stop
function does not start
the internal combustion
engine. The READY indi-
cator in the multifunc-
tion display is off. The ECO start/stop function has failed. The warning and indicator
lamps in the instrument cluster light up. X
Shift the transmission to P .X
Switch off the ignition and turn it back on. X

Driving and parking Z

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).

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
