12 volt power socket
The 12 v
o
lt power socket will only work with
the ignition on.
Using electrical appliances with the engine
stopped and the ignition switched on will
drain the battery. Therefore, electrical devi-
ces connected to the power socket can only
be used when the engine is running.
To prevent voltage variations from causing
damage, switch off the electrical consumer
connected to the 12 volt power socket before
switching the ignition on or off and before
starting the engine.
12 volt power sockets can be found in the fol-
lowing locations in the vehicle:
● Compartment in the centre of the centre
conso
le.
● Compartment in the front centre console.
● Storage compartment in the front central
armres

C onn e
cting an electrical appliance: plug the
device into the power socket as far as possi-
ble to unlock the built-in childproof lock. The current only flows when the childproof lock is
unloc
ked.

Flashing red light:There is some kind of fault
(e.g. disconnection due to ex-
cess current or temperature). Heat protection
The 230
V
o
lt Euro power connector converter
switches off automatically when a certain
temperature is exceeded. This disconnect
prevents overheating in the event of an in-
crease in power consumption of the connec-
ted appliance and where the atmospheric
temperature is too high. The inverter will
switch on again automatically after it has
cooled down. Appliances that are switched
on and connected to the power socket will
start up again. Therefore, switch off all elec-
trical appliances connected to the power
socket when the current converter switches
off due to overheating. WARNING
High voltage in the electrical installation!
● Liquids must not be spilt over the power
sock et
. ●
Do not p lug a
dapters or extension cords in-
to the 230 Volt Euro power connector. Other-
wise, the built-in child safety device will
switch off and the connector will become live.
● Do not plug current conductors such as a
knitting needle int
o the 230 Volt Euro power
connector. CAUTION
● Alw a
ys follow the operating instructions for
the appliances to be connected!
● Never exceed the maximum power rating as
this c
ould damage the vehicle's general elec-
trical system.
● 12 volt power socket:
– Only u
se accessories with approved elec-
tromagnetic compatibility according to
current regulations.
– Never power the socket.
● 230 Volt Euro power socket:
– Do not plug in dev
ices or connectors that
are too heavy (e.g. a transformer) into the
power socket.
– Do not connect lamps which contain a ne-
on tube.
– Only plug appliances with a voltage that
matches the power socket voltage into
the power socket.
– Where devices have with a high start-up
current, surge protection prevents them
from switching on. In this case, unplug 172

Automatic air recirculation mode
Fresh air enters the vehicle interior in posi-

The system is unable to detect unpleasant
smells.
With the following outside temperatures and
conditions the air recirculation does not
switch on automatically:
● The cooling system is switched on (the ACbutton is lit up) and the outside temperature

WARNING
Never program the independent heating sys-
tem t o be activ
ated and operated in closed,
unventilated areas. The auxiliary heater
fumes contain carbon dioxide, an odourless
and colourless toxic gas. Carbon monoxide
can cause people to lose consciousness. It
can also cause death. Operating instructions
The auxiliary heater exhaust system located
below the
v
ehicle must be kept clear of snow,
mud and other objects. The exhaust gases
must not be obstructed in any way. The ex-
haust gases generated by the auxiliary heater
are removed via an exhaust pipe fitted under-
neath the vehicle.
On heating the vehicle interior, depending on
the outside temperature the warm air is first
directed at the windscreen and then to the
rest of the vehicle interior through the air
vents. If the air vents are turned towards the
windows, for example, the form of air distri-
bution may be affected.
Depending on the outside temperature, the
temperature at which the auxiliary heater
warms the vehicle interior may be somewhat
higher if the heating or air conditioner tem-
perature control is set to maximum before
switching the heating on.
Depending on the engine, vehicles with aux-
iliary heater may be fitted with a second bat-
tery in the luggage compartment that is re-
sponsible for powering the auxiliary heater.
When will the auxiliary heater will not switch
on?
● The auxiliary heater requires about as
much po w
er as the dipped beam headlights.
180
Driving
If the battery charge is low, the auxiliary heat-
er w i
l
l switch off automatically or will not
even switch on. This avoids problems when
starting the engine.
● The heater will switch on just once each
time. The timer wi
ll also have to be switched
back on every time it is required. Note
● Noise w i
ll be heard while the auxiliary
heater is running.
● When the air humidity is high and the out-
side temper
ature low, the heating system
may evaporate condensation from the auxili-
ary heater. In this case, steam may be re-
leased from underneath the vehicle. This is
completely normal and there is no need to
suspect a fault!
● If the auxiliary heater runs several times
over a pr
olonged period, the vehicle battery
may run flat. To re-charge the battery, drive
the vehicle for a long distance. As a general
rule, drive for as much time as the auxiliary
heating was working. Driving

Introduction The power steering is not hydraulic but elec-
tromec
h
anical. The advantage of this steer-
ing system is that it disposes of hydraulic
tubes, hydraulic oil, the pump, filter and oth-
er components. The electromechanical sys-
tem saves fuel. While a hydraulic system re-
quires oil pressure to be maintained, electro-
mechanical steering only requires energy
when the steering wheel is turned.
With the power steering system, the assisted
steering function automatically adjusts ac-
cording to the vehicle speed, the steering tor-
que and the wheel turning angle. The power
steering only works when the engine is run-
ning. WARNING
If the power steering is not working then the
st eerin
g wheel is much more difficult to turn
and the vehicle more difficult to control.
● The power steering only works when the
engine is
running.
● Never allow the vehicle to move when the
engine is
switched off.
● Never remove the key from the ignition if
the vehic
le is in motion. The steering may lock and it will not be possible to turn the
st
eerin
g wheel. Control and warning lamps

WARNING
Turning off the engine while driving will make
st op
ping the vehicle difficult; this could even
result in the loss of control causing an acci-
dent with serious consequences.
● The assisted braking and steering systems,
the airbag sys
tem, seat belts and certain
safety equipment are only active while the
engine is running.
● The engine should only be switched off
when the vehic
le is at a standstill. WARNING
While the engine is running or starting it
cou l
d help reduce the risk of serious injury.
● Never start or leave the engine running in
poorly v
entilated or closed spaces. Exhaust
gas contains carbon monoxide, a toxic, col-
ourless and odourless gas. Carbon monoxide
can cause people to lose consciousness. It
can also cause death.
● Never leave the vehicle unattended if the
engine is
running. The vehicle could move off
suddenly or something unexpected could
happen resulting in damage and serious in-
jury.
● Never use start boosters. Cold start sprays
coul
d explode or increase the engine speed
unexpectedly. WARNING
The components of the exhaust system reach
ver y
high temperatures. This could cause a
fire and considerable damage.
● Always park your vehicle so that no part of
the exhau
st system can come in contact with
flammable materials (such as wood, leaves,
dried grass, spilled fuel, etc.).
● Do not apply additional underseal or anti-
corro
sion coatings to the exhaust pipes, cata-
lytic converter, heat shields or the diesel par-
ticulate filter. Ignition lock
