WARNING Risk of bur
ns or frostbite due to
being too close to the air vents
Very hot or very cold air can Oo
w from the air
vents. 
Make sure that all vehicle occupants
alw
ays maintain a suPcient distance
from the air vents. 
If necessary, direct the airOo
w to another
area of the vehicle interior. To guarantee the Oo

w of fresh air through the air
vents into the vehicle interior, note the following:
= Always keep the vents and ventilation grilles in
the vehicle interior clear.
= Keep the air inlet free of residue build-up
( page 390). 
To open or close: hold t
he centre of air
vent 1 and turn it to the les (open) or right
(closed) as far as it will go. 
To set the airOo

WARNING Risk of c
hemical burns and poi-
soning from damaged high-voltage battery
If the housing of the high-voltage battery has
been damag
ed, electrolyte and gases may
leak out. 
Avoid contact with the skin, eyes or
clo

thing. 
Immediately rinse electrolyte splashes
oM wit

h water and seek medical atten-
tion straight away. &
DANGER Risk of Nr
e and explosion from
excessive internal pressure of the high-
voltage battery
In the event of a vehicle Nr
e, Oammable gas
can escape and ignite. 
Stop the charging process immediately
in case of unusual odour

s, smoke or
burn marks. 
Leave the danger zone immediately.
Secur

e the danger zone at a suPcient
distance. 
Call the Nr
e service. The hybrid system combines a combustion engine
wit
h an electric motor.
Characteristics when the vehicle is at a standstill: = The combustion engine is generally switched
oM.
= Idle speed occurs only in certain instances.
Characteristics when the vehicle is started: = If the high-voltage battery is suPciently
charged, the vehicle can be started with the
electric drive system without the combustion
engine (noiseless start).
= If the high-voltage battery for the electric drive
system is not suPciently charged or the vehi-
cle conditions for a silent start are not met, the vehicle will start with the combustion
engine.
% Depending on the system, it may be that even
t
hough the high-voltage battery is charged,
electric mode has restricted or no availability.
Once the combustion engine has been oper-
ated for long enough, electric mode will be
again available without restriction.
Characteristics with moderate power output
r
equests:
= The combustion engine is switched oM as
osen as possible during the journey.
= The vehicle can, depending on the drive pro-
gram selected and the state of charge of the
high-voltage battery, be accelerated electri-
cally up to speeds of approximately
140 km/h.
Characteristics with high power output requests:
= The electric motor supports the combustion
engine (boost eMect), e.g. when you pull away
or accelerate.
= The high-voltage battery is discharging. 176
Driving and parking

Characteristics when the accelerator pedal is
r
eleased during the journey:
= The electric motor will be operated as an alter-
nator when in overrun mode and during brak-
ing.
= The high-voltage battery is charging.
Notes on electric mode: = Vehicles with hybrid systems generate signiN-
cantly less noise when stationary and when
being driven than vehicles with combustion
engines.
= When you are driving in electric mode, the
vehicle may not be heard by other road users
due to the signiNcantly reduced noise gener-
ated.
It is for this reason that the vehicle is equip-
ped with a sound generator, which serves as
an acoustic vehicle alert system (AVAS).
= If not all the vehicle conditions for electric
mode are met, the combustion engine will be
switched on.
% Vehicles with diesel particulate Nlt
ers: during
the regeneration of the diesel particulate Nl-ter, t
he drive programmes are not available or
are restricted and the charge level of the high-
voltage battery may change.
Notes on the acoustic vehicle alert system:
= The sound g

enerator generates speed-depend-
ent vehicle noise emissions when the vehicle
is driving forwards or reversing at a speed of
up to around 30 km/h.
= This helps other road users, particularly
pedestrians and cyclists, to hear your vehicle
better.
= When you drive at speeds above 20 km/h the
acoustic vehicle alert system will gradually
switch oM.
= The sound generator will be oM when the vehi-
cle is stationary.
qManual disconnection of t

he high-voltage on-
board electrical system &
DANGER Risk of deat
h and Nre due to
modiNed and/or damaged components of
the high-voltage on-board electrical sys-
tem
The vehicle's high-voltage on-board electrical
sy
stem is under high voltage. If you modify
component parts in the vehicle's high-voltage
on-board electrical system or touch damaged
component parts, you may be electrocuted. In
addition, modiNed and/or damaged compo-
nents may cause a Nre.
In the event of an accident or impact to the
vehicle underbody, components of the high-
voltage electrical system may be damaged
although the damage is not visible. 
Never make any modiNcations t
o the
high-voltage on-board electrical system. 
Do not switch on or use the vehicle if its
high-v
oltage on-board electrical system Driving and parking
177

components have been
modiNed or dam-
ag ed. 
Never touch damaged components of
t

he high-voltage on-board electrical sys-
tem. 
Aser an accident, do no
t touch any com-
ponents of the high-voltage on-board
electrical system. 
Aser an accident, ha
ve the vehicle trans-
ported away. 
Have the components of the high-voltage
on-boar
d electrical system checked at a
qualiNed specialist workshop and
replaced if necessary. Requirements:
Onl

y disconnect the high-voltage on-board electri-
cal system manually in the following situations:
= The 6 restraint system warning lamp lights
up in the driver's display, e.g. aser an acci-
dent. =
The v
ehicle is badly damaged, e.g. aser an
accident, and the restraint system compo-
nents have not been triggered.

Switch oM t
he vehicle. 
Shis t
he transmission to position j. 
Apply the electric parking brake. 
Secure the vehicle against rolling away. 
Open the bonnet. 
Press release tab 1 in t
he direction of the
arrow and pull it out. 
Pull high-voltage disconnect device 2 in t
he
direction of the arrow until it engages.
The high-voltage on-board electrical system is
switched oM.
All work on the hybrid drive system (including
aser disconnecting t

he high-voltage on-board
electrical system manually) may only be carried
out in a qualiNed specialist workshop.178

WARNING Risk of accident and injur y due
to leaving children unattended in the vehi-
cle
If children are les unatt
ended in the vehicle,
they could, in particular:
= open doors, thereby endangering other
persons or road users.
= get out and be struck by oncoming traPc.
= operate vehicle equipment and become
trapped, for example.
In addition, the children could also set the
vehicle in motion by, for example:
= releasing the parking brake.
= changing the transmission position.
= starting the vehicle. 
Never leave children unattended in the
v
ehicle. 
When leaving the vehicle, always take the
k
ey with you and lock the vehicle. 
Keep the vehicle key out of the reach of
c
hildren. Requirements:
= The k

ey is in the vehicle and is recognised.
= The brake pedal is not depressed. 
To switch on the power supply: pr
ess button
1 once.
You can, for example, switch on the wind-
screen wiper.
The power supply will be switched oM ag
ain if the
following conditions are met:
= You open the driver's door.
= You press button 1 twice more. 
To switch on the vehicle: pr
ess button 1
twice.
Indicator and warning lamps will light up on
the driver's display.
The vehicle will be switched oM ag
ain if one of the
following conditions is met:
= You do not start the vehicle within 15 minutes
and the transmission is in position j or the
electric parking brake is applied.
= You press button 1 once. Driving and parking

DANGER Risk of f
atal injuries due to
exhaust gases
Combustion engines emit poisonous exhaust
g
ases such as carbon monoxide. Breathing in
these exhaust gases is hazardous to health
and results in poisoning. 
Never leave the engine and, if present,
t

he stationary heater, running in an
enclosed space without suPcient venti-
lation. &
WARNING Risk of Nr
e due to Oammable
material in the engine compartment or the
exhaust system
Flammable materials may ignite. 
Therefore, check regularly that there are
no Oammable mat

erials in the engine
compartment or on the exhaust system. Requirements:
= The k

ey is in the vehicle and is recognised. 
Shis t
he transmission to position j or i. 
Depress the brake pedal and press button 1
once.
