– Press 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 circumstances. It is possible to select
interior temperatures from +16° C (6 1° F) to +29.5° C (86° F). These are
approximate temperatures and the actual temperature may be slightly higher
or lower depending on the ambient conditions. Climatronic 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 n
eed 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, air flow 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 temperat ure, air flow and distribution as required.Switching on manual mode
– To enter manual mode, press one of the buttons ⇒fig. 108 to , or press the air flow control . The symbol will
disappear from the display.

Heating, ventilation and air conditioning
144Temperature
There are separate temperature selectors for the left and right sides of the
vehicle interior. The selected temperatur e is displayed above the selector. It
is possible to select interior temper atures 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 tempera-
ture is not regulated.
Blower
The air flow 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, turns 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 th e 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 143, fig. 108 to switch air recir-
culation mode on or off. It is sw itched on if the following symbol
appears in the display

.
Air recirculation mode pr events strong odours in the ambient air from
entering the vehicle interior, for example when passing through a tunnel or in
queuing traffic.
With low ambient temperatures, the air recirculation increases the effective-
ness of the heating system by heating the air inside the passenger compart-
ment rather than the ambient air.
With high ambient temperatures, the ai r 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.

General notesThe pollen filter
The pollen filter (a combined particle 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 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 filter 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. 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.
