Heating
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 is not running.
● The blower is switched off.
● The outside temperature is below +3 °C.
● The air conditioning system compressor 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 speci-
alised workshop. 
Air recirculation mode 
Air recirculation mode prevents fumes or unpleasant smells from coming from the outside.

159
Air conditioning
Air recirculation mode ⇒ fig. 129 
prevents strong odours in the outside
air from entering the vehicle interior, for example when passing through a
tunnel or in queuing traffic.
With low temperatures outside, the air recirculation increases the effective-
ness of the heating system by warming the air inside the vehicle rather than
the cold air from outside.
With high outside temperatures, the air recirculation increases the effective-
ness of the air conditioning system by cooling the air inside the vehicle
rather than the ambient air.
If the windscreen air output is on and the air recirculation mode is pressed,
this remains active. When the recirculation mode is on, if the air distribution towards the windscreen mode is selected, the recirculation mode is deacti-
vated. For safety reasons, the air recirculation mode should not be connec-
ted.
WARNING
In air recirculation mode, no cold air from the outside enters the vehicle
interior. If the air conditioning system is switched off, the windows can
quickly mist over. Therefore, never leave the air recirculation mode
switched on for a long time (risk of accident).

The LEDs on the Climatronic controls indicate that the selected function has
been activated.
In addition, the radio or radio and navigation displays mounted at factory
briefly display the current settings of the Climatronic if any are modified.
The symbols used on the radio or radio and navigation displays are the
same as the symbols used for the Climatronic controls. 
Automatic mode
In automatic mode air temperature, air flow and distribution
are automatically regulated so that a specified temperature
is attained as quickly as possible and then maintained. The temperature can be adjusted separately for the left and right
sides of the vehicle interior.
Switching on automatic mode
– Press AUTO
⇒ 
fig. 130. “AUTO High” is shown on the radio dis-
play (high fan speed).
– Press AUTO
again ⇒ 
fig. 130. “AUTO Low” is shown on the radio
display (low fan speed).
Depending upon the version and finish, the vehicle may include: When a temperature of 22 °C (72 °F) is set in automatic mode a comfortable
interior climate is quickly reached. Therefore, we recommend you not to
change this adjustment, except as necessary to suit individual preferences
or particular circumstances. The inside temperature can be set between
+18 °C (64 °F) and +26 °C (80 °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. The temperature of the air
supplied to the interior, the blower speed and the air distribution are regu-
lated automatically. The system also considers the sunlight radiation, so
there is no need for manual readjustment. Therefore,
automatic mode al-
most always provides the best comfort for the vehicle occupants throughout
the year.
Automatic mode is switched off whenever an adjustment is made using the
buttons for the air distribution, air flow or 
or the air recirculation button
. The temperature will continue to be regulated within the parameters
manually selected by the user.
Note
There are two automatic modes:
● Automatic mode LO: This calculates the air flow for two people.
● Automatic mode HI: This calculates the air flow for more than two peo-
ple. 

Switching on manual mode
– To enter manual mode, press one of the buttons ⇒ fig. 133 1
to 5 or press the air flow control 10. The selected function is
shown on the radio or navigator display.
Temperature
There are separate temperature selectors for the left and right sides of the
vehicle interior. The selected temperature is displayed above the selector.
The inside temperature can be set between +18 °C (64 °F) and +26 °C
(80 °F). These are approximate temperatures and the actual temperature
may be slightly higher or lower depending on the ambient 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 tempera-
ture is not regulated. If a temperature above 26 °C (80 °F) is selected, the display switches to
HI
In this setting the system runs at maximum heating output and the temper-
ature is not regulated.
Blower
The air flow may be adjusted freely using the control 10
. 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.

164Air conditioning
When the AC
button is off (LED off), the air conditioning system is off.
When the AC
button is off, the air conditioning system is switched off to
save fuel. The temperature continues to self-regulate. The set temperature
can then only be reached if it is higher than the outside temperature.
Driver and passenger temperature control
The DUAL
button controls the synchronisation of the 2 Climatronic climate
zones.
When the DUAL
button is on (LED lit), the climate zone of the Climatronic is
personalised, for example: Driver side temperature 22 °C and passenger
side temperature 23 °C.
When the DUAL
button is off (LED off), the climate zone of the Climatronic is
synchronised, for example: Driver side temperature 22 °C and passenger
side temperature 22 °C.
If the DUAL
button is off and the passenger side temperature is changed,
the function is automatically activated. 
Air recirculation mode
Air recirculation mode prevents fumes or unpleasant smells
from coming from the outside. – Press the button 
⇒ fig. 133
2 to switch air recirculation
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 enter-
ing the vehicle interior, for example when passing through a tunnel or in a
traffic jam. With low outside temperatures, the air recirculation increases the effective-
ness of the heating system by heating the air inside the vehicle rather than
the air from outside.
With high outside temperatures, the air recirculation increases the effective-
ness of the air conditioning system by cooling the air inside the vehicle
rather than the ambient air.
If the windscreen air output is on and the air recirculation mode is pressed,
this remains active. When the recirculation mode is on, if the air distribution
towards the windscreen mode is selected, the recirculation mode is deacti-
vated. For safety reasons, the air recirculation mode should not be connec-
ted.
WARNING
In air recirculation mode, no cold air from the outside enters the vehicle
interior. If the air conditioning system is switched off, the windows can
quickly mist over. Therefore, never leave the air recirculation mode
switched on for a long time (risk of accident).

General notes
Pollution filter
The pollution filter (a combined particulate filter and active carbon filter)
serves as a barrier against impurities in the outside air, including dust and
pollen.
For the air conditioner to work with maximum efficiency, the pollution filter
must be replaced at the intervals specified in the Service Schedule.
If the filter loses efficiency prematurely due to use in areas reaching very
high pollution levels, the pollen filter must be changed more frequently
than stated in the Service Schedule. 

Air conditioning
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 is not running.
● The AC
button is disconnected.
● The outside temperature is below +3 °C.
● The air conditioning system compressor 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 speci-
alised workshop.
CAUTION
● If you suspect that the air conditioner is damaged, switch it off with but-
ton AC
to prevent further damage and have it checked by a specialised
workshop.
● Repairs to the air conditioner require specialist knowledge and special
tools. Therefore, we recommend you to take the vehicle to a specialised
workshop.
Note
● If the humidity and temperature outside the vehicle are high, condensa-
tion can drip off the evaporator in the cooling system and so forming a pud-
dle underneath 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 are not impaired, and to prevent the
windows from misting over. ●
The air from the vents flows through the vehicle interior and is extracted
by slots designed for this purpose. Therefore, do not cover these slots with
items of clothing or other objects.
● The air conditioner operates most effectively with the windows and the
sliding/tilting sunroof* closed. However, if the temperature inside the vehi-
cle is excessive because of the sun, the air inside can be cooled faster by
opening the windows for a short time.
● 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.
● It is advisable to connect the air conditioning at least once a month, to
lubricate 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. 
