Maximum heat output, which is needed to defrost the windows quickly, is
only available when the engine has reached its operating temperature.
Coolant system
When the cooling system is switched on , not only the temperature, but also
the air humidity in the vehicle interior is reduced. This improves comfort for
the vehicle occupants and prevents misting of the windows when the outside
air humidity is high.
If the cooling system cannot be switched on this may be due to the following
reasons:•
the engine is not running.
•
The blower is switched off.
•
The outside temperature is lower than +5°C.
•
the cooling system compressor has been temporarily switched off
because the engine coolant temperature is too high.
•
The air conditioning fuse is faulty.
•
Another fault in the vehicle. Have the air conditioning checked by a qual-
ified workshop.
Air recirculation
Air recirculation mode prevents fumes or unpleasant smells
from entering the vehicle.When air recirculation mode is switched on (button ⇒page 120, fig. 91
with warning lamp) strong odours in th e outside air do not enter the vehicle
interior, for example when passing th rough a tunnel or in queuing traffic.
When the outside temperature is low, using air recirculation mode provides
more effective heating by heating air from the vehicle interior instead of cold
air from outside.
When the outside temperature is high, using air recirculation mode provides
more effective cooling by cooling air from the vehicle interior instead of warm
air from outside.
For reasons of safety, air recirculation is not possible when the control for air
distribution is set to the windscreen setting
.
WARNING
In air recirculation mode, no ambient air enters the vehicle interior. If the
air conditioning system is switched off, the windows can quickly mist over.
Therefore, you should never leave the air recirculation mode switched on
for longer periods, as this increases the risk of an accident.
Note
•
When reverse gear is engaged the air recirculation connects automatically
to prevent the entrance of exhaust fumes in the vehicle on travelling back-
wards. The control light on the button does not light up.
•
If the temperature control is turned to the coldest setting (blue point) and
the switch is activated, the “Air recirculation” function is automatically
activated in order to cool the passenger compartment rapidly using a
minimum of energy and the fu nction indicator will light.

Economic use of the air conditioningWhen the air conditioning is switched on, the compressor consumes engine
power and has an effect on fuel co nsumption. Observe the following points
in order to have the equipment operating for a short a time as possible.
•
If the vehicle interior has overheated due to excessive solar radiation, it is
best to open the windows or doors to allow the hot air to escape.
•
When travelling the air conditioning should not be switched on if the
windows or sun roof are open.*

+22°C (72°F) is set in automatic mode. It can be changed as necessary to suit
individual preferences or particular ci rcumstances. It is possible to select
interior temperatures from +18°C (64°F) to +29°C (86°F). If a lower or higher
temperature is selected, LO or HI is displayed on the screen. These are
approximate temperatures and the actual temperature may be slightly higher
or lower depending on the outside conditions.

Heating, Ventilation and Air conditioning
124Climatronic maintains a constant temperature level fully automatically. The
temperature of the air supplied to the interior, the blower speed and the air
distribution are regulated automatically. The system also allows for the effect
of strong sunlight, so there is no need for manual adjustment. Therefore,
automatic mode provides the best comfort for the vehicle occupants in virtu-
ally all conditions throughout the year.
Automatic mode is switched off whenever an adjustment is made using the
buttons for the air distribution, blower or . The temperature continues
to be regulated.Manual mode
In manual mode you can adjust the air temperature, flow, and
distribution yourself.Switching on manual mode

the blower control . The display is switched off .Temperature
It is possible to select interior te mperatures from +18°C (64°F) to +29°C
(86°F). These are approximate temperat ures and the actual temperature may
be slightly higher or lower depen ding on the outside conditions.
If a temperature below 18°C (64°F) is selected, the display switches to LO. In
this setting the system runs at maximum cooling output and the temperature
is not regulated.
If a temperature above 29°C (86°F) is selected the display indicates HI . In this
setting the system runs at maximum heating output and the temperature is
not controlled. Blower
The blower can be infinitely adjusted
with the blower control . Always have
the blower running at a low setting to ensure a constant flow of fresh air into
the vehicle. If the blower is switched off (no level displayed ) and the
control is turned further to the left, th e Climatronic is switched off. Then OFF

Te c h n i c a l D a t a
When the outside temperature is high, using air recirculation mode provides
more effective cooling by cooling air fr
om the vehicle interior instead of warm
air from outside.
For reasons of safety, air recirculation is not possible when the control for air
distribution is set to the windscreen setting
.
WARNING
In air recirculation mode, no ambient air enters the vehicle interior. If the
air conditioning system is switched of f, the windows can quickly mist over.
Therefore, you should never leave the air recirculation mode switched on
for longer periods, as this increases the risk of an accident.
Note
When reverse gear is engaged the air recirculation connects automatically to
prevent the entrance of exhaust fumes in the vehicle on travelling backwards.
In this case the symbol for air recirculation is not displayed.General notesThe pollen filter
The pollution filter (a combined particulate filter and active carbon filter)
serves as a barrier against impurities in the ambient air, including dust and
pollen.
For the air conditioning system to work with maximum efficiency, the pollen
filter must be replaced at the interv als specified in the Maintenance Program.
If the filter loses efficiency prematurely due to use in areas with very high
levels of air pollution, the pollen filter must be changed more frequently than
stated in the Service Schedule.
Caution
•
If you suspect that the air conditioning is damaged, switch off the air
conditioning with button to prevent further damage and have it
checked by a qualified workshop.
•
Repairs to the air conditioning system require specialist knowledge and
special tools. Therefore, we recommend that you take the vehicle to a quali-
fied workshop should problems occur.Note
•
If the humidity and temperature outside the vehicle are high, condensa-
tion can drip off the evaporator in the cooling system and form a pool under-
neath the vehicle, this is completely normal and there is no need to suspect
a leak.
•
Keep the air intake slots in front of the windscreen free of snow, ice and
leaves to ensure heating and cooling is not impaired, and to prevent the
windows misting over.
•
The air from the vents flows through the passenger compartment and is
extracted by slots designed for this purpose. Do not cover these slots with
articles of clothing or other objects.
•
The air conditioning system operates most effectively with the windows
and the sliding/tilting roof* closed. However, if the sun has heated up the
vehicle, the air inside can be cooled more quickly by opening the windows for
a short period.
•
Do not smoke while air recirculation mode is on, as smoke drawn into the
air conditioning system leaves a residue on the evaporator, producing a
permanent unpleasant odour.
•
At low outside temperatures the comp ressor switches off automatically.
The button cannot be switched on either.
•
It is advisable to connect the air conditioning at least once a month, to
lubricate the system gasket s and prevent leaks. If a decrease in the cooling
capacity is detected, an Authorised Service Centre should be consulted to
check the system.
