Heating and air conditioning system

The air conditioning only operates if button
⇒fig. 101
is pressed and the
following conditions are met:•
engine running,
•
outside temperature above +5 °C and
•
blower switch switched
on (positions 1 to 4).
If the cooling system is switched on, the temperature and air humidity drops in the vehicle. The wellbeing of the occupants of
the car is enhanced as a result of this
particularly at high outside temperatures and a high air humidity. The system prevents the windows misting up during the cold season of the year. The heating effect is dependent upon th
e coolant temperature, thus full heat
output only occurs when the engine
has reached its operating temperature.
It is possible to briefly activate recirc
ulated air mode in order to enhance the
cooling effect
⇒
.
Air at a temperature of about 5°C may flow
out of the vents under certain circum-
stances when the cooling system is operating. Lengthy and uneven distribution of the air flow out of the vents (in particular at the leg area) and large differences in temperature, for example when getting out of
the vehicle, can result in chills in
sensitive persons. The air inlet in front of the windscreen must be free of ice, snow or leaves in order to ensure that the heating and cooling systems operate properly. After switching on the cooling
Condensation
from the evaporator of the air condi-
tioning may drip down and form a puddle
below the vehicle. This is quite normal
and not an indication of a leak!
WARNING
•
For your own safety and that of other road users, ensure that all the
windows are free of ice, snow and mistin
g. Please familiarize yourself about
how to correctly operate th
e heating and ventilation systems, how to demist
and defrost the windows, as well as with the cooling mode.•
You should not leave recirculated air mode on over a longer period of
time, as “stale” air may result in fatigue in the driver and occupants, divert your attention and also cause the windows to mist up. The risk of having an
accident increases. Switch recirculated air mode off as soon as the windows begin misting up.
Note
•
We recommend that you do not smoke in the vehicle when the recirculating air
mode is operating since the smoke which is drawn at the evaporator from the inte- rior of the vehicle forms deposits in the
evaporator of the air conditioning system.
This produces a permanent odour when th
e air conditioning system is operating
which can only be eliminated through co
nsiderable effort and expense (replace-
ment of compressor).Using the systemSetting temperature – Turn the control dial

•
The whole heat output will be needed
to unfrost the windscreen and side
windows. No warm air will be fed to the footwell. This can lead to restriction of the heating comfort.•
The used air streams out through the air removal openings in the luggage
compartment.•
If the cooling system has not been switched on for a lengthy period, odours may
be produced at the evaporator because of
deposits. Switch the cooling system on
at least once a month for approximately 5 mi
nutes at the highest blower stage - also
during the cold season of the year - in
order to remove such odours. Also open a
window for a short time.•

Recirculated air mode In recirculated air mode air is sucked

WARNING
You should not leave recirculated air mode on over a longer period of time, as “stale” air may result in fatigue in the driver and occupants, divert your attention and also cause the windows to mist up. The risk of having an acci-
dent increases. Switch recirculated air mode off as soon as the windows begin misting up.Using the air conditioning system economicallyThe compressor on the air co
nditioning system uses po
wer from the engine when
in cooling mode which will effect the fuel consumption. It recommended to open the windows or the doors of a vehicle for which the inte- rior has been strongly heated through the ef
fect of direct sunlight in order to allow
the heated air to escape. The cooling system should not be switched on while travelling when the window is open. The desired interior temperature can also be achieved without switching in the cooling system just by switching to fresh air mode.
For the sake of the environment
When you economize on fuel, you also reduce pollutant emissions.

Climatronic* (automatic air conditioning)Description The Climatronic system is a combin
ation of an automatic heating,
fresh air and cooling system which provides optimal comfort for the occupants of the car.The Climatronic maintains a constant temp
erature fully automatically, once it has
been set. This is achiev
ed by automatically varying the temperature of the
outflowing air, the blower stages and the ai
r distribution. The system also takes into
account bright sunlight which eliminates
the need to alter the settings manually.
The
automatic mode
⇒page 90 ensures maximum wellbeing of the occupants at
all times of the year. Description of Climatronic system The cooling operates only if the following conditions are met:•
engine running,
•
outside temperature above +5 °C,

not
pressed.
If the cooling system is switched on, the temperature and air humidity drops in the vehicle. The wellbeing of the occupants of
the car is enhanced as a result of this

The air inlet in front of the windscreen must be free of ice, snow or leaves in order to ensure that the heating and cooling systems operate properly. The AC compressor is switched off at a hi

cooling at a high load of the engine.

matic mode, the changed functions remain
stored. Only the function “circulating

respectively. The temperature is not controlled in this case. Lengthy and uneven distribution of the air flow out of the vents (in particular at the leg area) and large differences in temperature, for example when getting out of the vehicle, can result in chills in sensitive persons.Controlling blower There are a total of six blower stages available.The Climatronic system controls the bl

WARNING
•
“Stale air” may result in fatigue in
the driver and occupants, reduce
attention levels and also cause the windows to mist up. The risk of having an accident increases.•
Do not switch the Climatronic syst
em off for longer than necessary.
•
Switch the Climatronic system on as soon as the windows mist up.
Operational problemsIf all the symbols on the display of the au
tomatic air conditioning system flash for
approx. 15 seconds after switching on the ignition, then there is a fault in the system - visit a specialist garage. If the cooling system does not oper
ate, the following faults may exist:
•
the outside temperature is lower than +5°C,
•
The compressor of the automatic air
conditioning system was temporarily
switched off due to a too high temperature of the coolant,•
a blown fuse.
Check the fuse, replace it if necessary
⇒page 192. If a blown fuse is not the source
of the fault, switch the Climatronic off and have it checked. If the cooling capacity decreases, switch
the Climatronic off and have it checked.

What influences the driving safety? The driving safety is primarily dete
rmined by the style of driving and
the personal behaviour of all the occupants.The driver is fully responsible for himself and his occupants. If your driving safety is effected, you place yourself and the oncomi
ng traffic at risk. Please refer to the
following guidelines.•
Do not get distracted from concentrating on the traffic situation, e.g. by your
occupants or mobile phone calls.•
Never drive when your driving ability is impaired, e.g. through medication,
alcohol, drugs.•
Keep to the traffic regulations and the permissible speed limit.
•
Adjust the driving speed at all times to the road condition as well as to the traffic
and weather conditions.•
Take regular breaks on long journe
ys - at the latest every two hours.
Correct seated positionCorrect seated position for the driver Correct seated position for the dr
iver is important for safe and
relaxed driving.For your own safety and to reduce the risk of injury in the event of an accident, we recommend the following setting:•
Adjust the steering wheel so that the distance between the steering wheel and
your chest is at least 25 cm
⇒fig. 111
.
•
Position the driver seat in the forward/back direction so that you are able to fully
press the pedals with your legs at a slight angle.
