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 382). 
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.

therwise you may fail to recognise
dangers.

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 combus

tion 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. 170
Driving and parking

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.
Characteristics when the accelerator pedal is
released 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:
= V
ehicles 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, the 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 t

o 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.

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. Driving and parking
171

In the event of an accident or impact to the
v ehicle 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
components have been modiNed or dam-
aged. 
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 vehicle is badly damaged, e.g. aser an
accident, and the restraint system compo-
nents have not been triggered. Operating the high-voltage disconnect device

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. =
oper
ate 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:
= t

he key 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 is switched oM ag
ain if the fol-
lowing conditions are met:
= you open the driver's door.
= you press button 1 twice more. Driving and parking
