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
unfasten your seat belt :R
a messag e appears in th e multifunction dis -
play and R
a warnin g tone sounds
Further information ( Y
page 45) .
Al l of th e vehicle' s systems remain active , if:R
th e vehicle is stationary R
th e combustion engin e is switched of f andR
th e READY indicator in th e instrumen t cluster
lights up
If you remov e your foot from th e brake peda l
whil e in transmissio n position D or R, th e vehicle
may pull away automatically.
Observ e th e note s on th e READY display of th e
EC O start/sto p function ( Y
page 23).
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
