CAUTION
Do not smoke when air recirculation is
switched on in vehicles with an air condition-
er. The smoke taken in could lie on the cool-
ing system vaporiser and on the activated
charcoal cartridge of the dust and pollen fil-
ter, leading to a permanently unpleasant
smell. Note
Climatronic: air recirculation mode switches
on to prevent exhaust gas from entering the
vehicle interior when it is in reverse and

Introduction The auxiliary heater is powered by fuel from
the vehicle's fuel tank and can be used while
the vehicle is in motion and at a standstill.
Select the mode required (
heat
or fan
)
››› page 130 on the dash panel.
In w int
er, the auxiliary heater can be used in
heat mode before switching on the ignition to
remove any ice, mist or snow from the wind-
screen (thin layers only). WARNING
The auxiliary heater fumes contain carbon di-
oxide, an odourless and colourless toxic gas.
Carbon monoxide can cause people to lose
consciousness. It can also cause death.
● Never switch on the auxiliary heater or
leave it running in places that are enclosed or
unventilated.
● Never program the independent heating
system to be activated and operated in
closed, unventilated areas. WARNING
The components of the auxiliary heater ex-
haust system heat up a great deal. This could
cause a fire.
● Always park your vehicle so that no part of
the exhaust system can come in contact with
flammable materials (such as dried grass). CAUTION
Never place food, medicines or other heat-
sensitive objects close to the air vents. Food,
medicines and other heat-sensitive objects
may be damaged or made unsuitable for use

When changing the battery, use another bat-
tery of the same model and observe the po-
larity when fitting it ››› .
Range
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. »

Operation
An optimum range is obtained by keeping
the remote control vertical, with the aerial
››› Fig. 124 A pointing upwards. When doing
so, do not cover the aerial with your fingers
or with the palm of your hand.
There must be a minimum distance of 2 me-
tr e
s between the remote control and the vehi-
cle. CAUTION
● The radio frequency 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 control. For this reason, always re-
place the used battery with another of the
same voltage, size and specifications. For the sake of the environment
● Please dispose of old batteries so that they
do not harm the environment.
● The remote control battery may contain
perchlorate. Observe the legal requirements
for their disposal. Programming the auxiliary heater

Driving
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
the vehicle. Stopping and starting the
engine
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
