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 special-
ised workshop.

Air recirculation mode
⇒page 152, fig. 109 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

In manual mode you can adjust the air temperature, air flow and distribution as required.Switching on manual mode
– To enter manual mode, press one of the buttons ⇒fig. 113 to
or press the air flow control . The selected function is
shown on the radio or navigator display.Te m p e r a t u r e
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 temperature
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 temperature
is not regulated.

Driver and passenger temperature control
The button controls the synchronisation of the 2 Climatronic climate
zones.
When the 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 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 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 ⇒page 157, fig. 113 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
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
connected.
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 notesPollution 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.

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 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 special-
ised workshop.Caution
•If you suspect that the air conditioner is damaged, switch it off with the button 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 work-
shop.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 puddle
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 th e 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 vehicle
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.
