Heating, Ventilation and Air conditioning
150With low outside temperatures, the air recirculation increases the effective-
ness of the heating system by warming the air inside the passenger compart-
ment rather than the ambient air.
Air distribution
Control for setting the flow of air in the required direction. – Air distribution towards the windsc reen. Air recirculation is, for safety
reasons, not possible in this position. – Air distribution to the upper body. – Air distribution to foot well – Air distribution to the windscreen and the foot well.
Blower
The airflow can be set at four speeds with the control . The airflow should
always be set at the lowest speed when driving slowly.
WARNING
•
For road safety all windows must be clear of ice, snow, and condensa-
tion. This is essential to ensure good visibility. Please familiarise yourself
with the correct operation of the heat ing and ventilation system, including
the anti-fog/defrost functions for the windows.
•
In air recirculation mode, no ambient air enters the vehicle interior. The
windows can quickly fog over if the heating is switched off. Therefore, you
should never leave the air recirculation mode switched on for longer
periods, as this increases the risk of an accident.Note
Please observe the general notes ⇒page 158.

Maximum heat output, which is needed to defrost the windows quickly, is
only available when the engine has reached its operating temperature.
Air conditioner
When the air conditioning 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 ambient air humidity is high.
If the air conditioning system cannot be
switched on this may be caused by
the following reasons:
•
The engine may not be running.
•
The blower is switched off.
•
The ambient air temperature is lower than +3°C.
•
The air conditioning system compress or has been temporarily switched
off because the engine coolant temperature is too high.
•
The air conditioner fuse is faulty.
•
Another fault in the vehicle. Have the air conditioner checked by a quali-
fied workshop.

– Press the temperature selectors to set the desired temperatures
for the left and right sides of the interior. We recommend 22°C
(72°F).A comfortable interior climate is quickly reached when a temperature of
+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 +16°C (61°F) to +29.5°C (86°F). These are approx-
imate temperatures and the actual temperature may be slightly higher or
lower depending on the ambient conditions. Climatronic automatically maintains a constant temperature. The tempera-
ture of the air supplied to the interior, the blower speed and the air distribu-
tion are regulated automatically. The system also allows for the effect of
strong sunlight, so there is no need
for manual adjustment. Therefore, auto-
matic mode provides the best comfort for the vehicle occupants in virtually all
conditions throughout the year.
Automatic mode is switched off whenever an adjustment is made using the
buttons for the air distribution, airflow or . The temperature will
continue to be regulated within the parameters manually selected by the
user.Manual mode
In manual mode you can adjust the air temper ature, airflow and distribution as required.Switching on manual mode
– To enter manual mode, press one of the buttons ⇒fig. 128 to , or press the airflow control . The symbol will

Temperature
There are separate temperature selectors for the left and right sides of the
vehicle interior. The selected temperature is displayed above the selector. It
is possible to select interior tem
peratures from +16°C (61°F) to +29.5°C
(86°F). These are approximate temperat ures and the actual temperature may
be slightly higher or lower depending on the ambient conditions.
If a temperature below 16°C (61°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 29.5°C (86°F) is selected the display switches to HI. In
this setting the system runs at maximum heating output and the temperature
is not regulated.
Blower
The airflow may be adjusted freely using the control . Always have the
blower running at a low setting to ensure a constant flow of fresh air into the
vehicle. Pushing the button
 to the minimum -1, tu rns the Climatronic off.
Air distribution
The air distribution is adjusted using the buttons , and . It is also
possible to open and close some of the air vents separately.
Switching the air conditioning system on and off
Pressing the button switches off the air conditioning system to save
fuel. The temperature continues to be regulated. The set temperature can
then only be reached if it is higher than the ambient temperature.
Air recirculation mode
Air recirculation mode prevents fumes or unpleasant smells
from entering the vehicle.– Press the button ⇒page 156, fig. 128 to switch air recir-
culation mode on or off. It is switched on if the following symbol
appears in the display

.
Air recirculation mode prevents strong odours in the ambient air from
entering the vehicle interior, for example when passing through a tunnel or in
queuing traffic.
With low outside temperatures, the air recirculation increases the effective-
ness of the heating system by warming the air inside the passenger compart-
ment rather than the ambient air.
With high ambient temperatures, the air recirculation increases the effective-
ness of the air conditioning system by cooling the air inside the passenger
compartment rather than the ambient air.
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.

Heating, Ventilation and Air conditioning
158General notesThe pollen filter
The pollution filter (a combined part iculate filter and active carbon filter)
serves as a barrier against impurities in the outside air, including dust and
pollen.
For the air conditioning system to work with maximum efficiency, the pollen
filter must be replaced at the intervals specified in the Service Schedule.
If the filter loses efficiency prematurely due to use in areas with very high
levels of air pollution, the pollen filte r must be changed more frequently than
stated in the Service Schedule.
Caution
•
If you suspect that the air conditioner is damaged, switch off the air condi-
tioner 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. Howe ver, 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 r esidue on the evaporator, producing a
permanent unpleasant odour.
•
The air conditioning should be turned on at least once a month, to lubri-
cate the system gaskets and prevent leaks. If a decrease in the cooling
capacity is detected, an Authorised Service Centre should be consulted to
check the system.
