If the air conditionin
g system cannot be
switched on, this may be caused by the fol-
lowing:
● The engine is not running.
● The fan is switched off.
● The air conditioning fuse is blown.
● The outside temperature is lower than ap-

imately +3°C (+38°F).
● The air conditioner compressor has been
temporari
ly switched off because the engine
coolant temperature is too high.
● Another fault in the vehicle. Have the air
conditioner chec
ked by a specialised work-
shop. Special features
If the humidity and t
emperature outside the
vehicle are high, condensation can drip off
the vaporiser in the cooling system and form
a pool underneath the vehicle. This is normal
and does not indicate a leak! Note
After starting the engine, any residual humid-
ity in the air c onditioner c

heat-sensitive, they may be damaged or
made unsuitable for use by the air coming
from the air vents. Note
The air from the vents flows through the vehi-

When the outside temperature is very high,
selecting manual air recirculation mode for a
short period refreshes the vehicle interior

WARNING
The auxiliary heater fumes contain carbon di-

ess and colourless toxic gas.
Carbon monoxide can cause people to lose
consciousness. It can also cause death.
● Never switch on the auxiliary heater or
leav

unventilated.
● Never program the independent heating
syst
em to be activated and operated in
closed, unventilated areas. WARNING
The components of the auxiliary heater ex-

cause a fire.
● Always park your vehicle so that no part of
the exhau
st system can come in contact with
flammable materials (such as dried grass). CAUTION
Never place food, medicines or other heat-

ton on the remote control once again.
Replacing the remote control battery
If the light ›››
Fig. 197 B on the remote con-
tr o
l
does not come on when the button is
pressed, the remote control battery should
soon be replaced.
The battery is located beneath a cover on the
back of the remote control. Turn the slot to
the left using a flat, blunt object (e.g. a coin).
When changing the battery, use another bat-
tery of the same model and observe the po-
larity when fitting it ››› .
R an
g
e
The receiver is in the interior of the vehicle.
The remote control, when fitted with new bat-
teries, has a range of several hundred me-
tres. Obstacles between the remote control
and the vehicle, bad weather conditions and
discharged batteries can considerably reduce
the range of the remote control. An optimum range is obtained by keeping
the remote c
ontrol vertical, with the aerial
››› Fig. 197 A pointing upwards. When doing
so , do not
c
over the aerial with your fingers
or with the palm of your hand.
There must be a minimum distance of 2 me-
tres between the remote control and the vehi-
cle. CAUTION
● The ra dio fr
equency remote control con-
tains electronic components. Therefore, avoid
getting it wet and being knocked and protect
it from direct sunlight.
● Use of inappropriate batteries may damage
the remote c
ontrol. For this reason, always re-
place the used battery with another of the
same voltage, size and specifications. For the sake of the environment
● Ple a
se dispose of old batteries so that they
do not harm the environment.
● The remote control battery may contain
perch
lorate. Observe the legal requirements
for their disposal. Programming the auxiliary heater

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
Page 183 of 320

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
