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 the   button 
⇒page 165, fig. 129 . “AUTO High” is 
shown on the radio display (high fan speed).
– Press the   button again  ⇒page 165, fig. 129 . “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 ad just m en t, excep t as ne ce ssa r y  to  sui t in di vid ua l pre fe re nces o r  
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 almost 
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 
people.

168Manual mode
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. 132  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.
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 on and off
When the   button is on (LED lit), the air conditioning system is on.
When the   button is off (LED off), the air conditioning system is off.Fig. 132  On the dash panel: 2C Climatronic controls.

then only be reached if it is higher than the outside temperature.
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 168, fig. 132    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.
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

Air conditioning
170comfort 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 button   to prevent further damage and have it checked by a specialised work-
shop.•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 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 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.
