The interior cooling system only works when
the engine is running and fan is switched on.
The air conditioner operates most effectively
with the windows and the electric sliding
panoramic roof closed. However, if the vehi-
cle has heated up after standing in the sun
for some time, the air inside can be cooled
more quickly by opening the windows and
the sliding electric panoramic sunroof briefly.Setting for conditions of optimal visibility
When the air conditioning is switched on, the
temperature and the air humidity in the vehi-
cle interior drop. In this way, when the out-
side air humidity is high, the windows do not
mist over and comfort for the vehicle occu-
pants is improved.

The cooling system does not switch on
If the air conditioning 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-
proximately +3 °C (+38 °F).
● The air conditioner compressor has been
temporarily switched off because the engine
coolant temperature is too high.
● Another fault in the vehicle. Have the air
conditioner checked by a specialised work-
shop.
Things to note
If the humidity and temperature 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 conditioner could mist over the
windscreen. Switch on the defrost function as
soon as possible to clear the windscreen of
condensation. Air vents

Operating instructions The auxiliary heater exhaust system located
below the vehicle 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.
Cases in which the auxiliary heater will not
switch on
● The auxiliary heater requires about as
much power as the dipped beam headlights.
If the battery charge is low, the auxiliary heat- er will 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 will also have to be switched
back on every time it is required. Note
● Noise will be heard while the auxiliary
heater is running.
● When the air humidity is high and the out-
side temperature 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 prolonged 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
Address Introduction The power steering is not hydraulic but elec-
tromechanical. 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
steering 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 vehicle is in motion. The steering may » 131Technical specifications

Electromechanical power steering
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.
You should remember that you will need con-
siderably more power than normal to steer
the vehicle if the power steering is not work-
ing correctly or not at all.
Counter steering assistance system
The counter steering assistance system helps
the driver in critical situations. Additional
steering power helps the driver when counter
steering. WARNING
The counter steering assistance system com-
bined with ESC helps the driver to steer the
vehicle in critical driving conditions. At all
times, it is the driver who steers the vehicle.
The counter steering system does not steer

Introduction Immobiliser display
When an invalid key is used or in the event of
a system fault,
or Immobiliser on is dis-
played on the instrument panel. The engine
cannot be started.
Pushing or towing
For technical reasons, the vehicle must not
be push- or tow-started. Jump starting is pref-
erable. WARNING
Turning off the engine while driving will make
stopping 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 system, seat belts and certain
safety equipment are only active while the
engine is running.
● The engine should only be switched off
when the vehicle is at a standstill. WARNING
While the engine is running or starting it
could help reduce the risk of serious injury. ●
Never start or leave the engine running in
poorly ventilated 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
could explode or increase the engine speed
unexpectedly. WARNING
The components of the exhaust system reach
very high temperatures. This could cause a
fire and considerable damage.
● Always park your vehicle so that no part of
the exhaust system can come in contact with
flammable materials (such as wood, leaves,
dried grass, spilled fuel, etc.).
● Do not apply additional underseal or anti-
corrosion coatings to the exhaust pipes, cata-
lytic converter, heat shields or the diesel par-
ticulate filter. 133

Unsuitable or careless use of the vehicle key
could result in serious injury.
● Always take all the keys with you whenever
you leave the vehicle. If not, the engine could
accidentally be started and electrical equip-
ment such as the windows could accidentally
be operated which may result in serious in-
jury.
● Never leave children or disabled people
alone in the car. Passengers could be trapped
in the car in an emergency and not be able to
get themselves to safety. For example, de-
pending on the time of the year, tempera-
tures inside a locked and closed vehicle can
be extremely high or extremely low resulting
in serious injuries and illness or even death,
particularly for young children.
● Never remove the key from the ignition if
the vehicle is in motion. The steering may
lock and it will not be possible to turn the
steering wheel. Note
● If the key is left in the ignition lock with the
engine off for long periods, the vehicle bat-
tery will run flat. ●
For automatic gearbox vehicles the key can
only be removed from the ignition lock if the
