Important safety notes
Danger of electric shock
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.
When towing a vehicle after an accident, be sure
to observe the following sections in the vehicle
Operator's Manual: R
Transporting the vehicle R
Towing the vehicle with the rear axle raised R
Towing a vehicle with both axles on the
ground
Read the safety instructions on towing and tow-
starting ( Y
page 53). 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.
The ignition must be switched off when carrying
out general tasks, such as changing bulbs or
checking the coolant level.
Automatic switching off of the hybrid
drive system If components of the restraint system are acti-
vated during an accident, the hybrid drive sys-
tem is automatically deactivated.
The hybrid drive system is not activated when
the vehicle is started if: R
an electrical short circuit is detected in the
hybrid drive system R
an electrical connection in the hybrid drive
system is disconnected
This ensures that you do not come into contact
with high voltage.
Manual switching off of the hybrid drive
system The hybrid drive system can be deactivated
manually using the high voltage switch-off
device.
! To prevent damage to the hybrid drive sys-
tem please observe the following instruc-
tions: R
only deactivate the hybrid drive system
manually in the following situations. R
work on the hybrid drive system may only
be carried out at a qualified specialist work-
shop, even when it has been deactivated
manually.
Deactivate the hybrid system manually if: R
the u restraint system warning lamp in the
instrument cluster lights up after an accident R
the vehicle is badly damaged, e.g. after an
accident, and the restraint system compo-
nents were not activated R
the vehicle is badly damaged and has to be
towed or transported10

Occupant safety
Restraint system warning lamp If the restraint system is disrupted, the high-
voltage on-board electrical system may not be
switched off in the event of an accident as inten-
ded.
G DANGER
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or may not deploy as
intended during an accident. This can affect
for example the Emergency Tensioning
Device or the air bag. Furthermore, in the
event of an accident, the vehicle's high-volt-
age electrical system may not be deactivated
as intended. You may be electrocuted if you
touch the damaged components of the vehi-
cle's high-voltage electrical system. This
poses an increased risk of injury or even fatal
injury.
Have the restraint system checked and
repaired in a qualified specialist workshop as
soon as possible. After an accident, switch off
the ignition immediately and remove the key
from the ignition lock.
A malfunction has occurred if the u restraint
system warning lamp: R
does not light up after the ignition is switched
on R
does not go out after a few seconds while the
combustion engine or hybrid system is run-
ning R
lights up again while the combustion engine
or hybrid system is running12

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.

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 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
