Operation
Heating and cooling the interior Fig. 116
On the dash panel: Climate controls. Interior heating
– Turn the temperature selector ››› Fig. 116
1 clockwise to select the desired tempera-
ture.
– Turn the blower switch to one of the set-
tings 1-4.
– Set the air distribution control to the air
flow configuration desired:  (towards the
windscreen),  (towards the chest),
(towards the footwell) and
 (towards the
windscreen and footwell areas).
Interior cooling
– Switch on the air conditioner using the but-
ton ››› Fig. 115
A/C .–
Turn the temperature selector anticlockwise
until the desired cooling output is reached.
– Turn the blower switch to one of the set-
tings 1-4.
– Use the air distribution regulator to guide
the airflow in the required direction  (to
the windscreen),  (to the upper body),
 (to the footwell) and
 (to the wind-
screen and to the footwell).
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 occu-
pants 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 fol-
lowing reasons:
● The engine is not running.
● The blower is switched off.
● The outside temperature is lower than ap-
proximately +3 °C (+37 °F).

Air conditioning
In manual mode you can adjust the air tem-
perature, air flow and distribution as re-
quired.
Switching on manual mode – To enter manual mode, press one of the
buttons ››› Fig. 120 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. It is possible to select interior
temperatures from +18 °C (+64 °F) to +26 °C
(+80 °F). These are approximate tempera-
tures and the actual temperature may be
slightly higher or lower depending on the
outside ambient conditions.
If you select temperatures below +18 °C
(+64 °F), the indication: LO will appear on the
screen. 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 se-
lected, the screen will show HI. In this setting
the system runs at maximum heating output
and the temperature is not regulated. Blower
The fan may be adjusted freely using the con-
trols
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, t urn
s the Climatronic off.
Air distribution
The air distribution is adjusted using the but-
tons  ,
 and
 . It is also possible to
open and close some of the air vents sepa-
rately.
Switching the air conditioning on and off
When the A/C button is on (LED lit), the air
conditioning system is on.
When the A/C button is off (LED off), the air
conditioning system is off.
When the A/C button is off, the air condition-
ing system is switched off to save fuel. The
temperature continues to self-regulate. The
set temperature can only be reached if it is
higher than the outside temperature.
Driver and passenger temperature control
The SYNC button controls the synchronisa-
tion of the 2 Climatronic climate zones.
When the SYNC button is off (LED off), the Cli-
matronic climate zone is personalised. For
example: driver side temperature +22 °C (+72 °F) and passenger side temperature +24
℃
(+23.89 ℃
).
When the S

YNC button is on (LED lit), the Cli-
matronic climate zone is synchronised. For
example: driver side temperature +22 °C
(+72 °F) and passenger side temperature +22
℃ (+22.22 ℃
).
If

the SYNC button is on and the passenger
side temperature is changed, the function is
automatically deactivated.
Air recirculation mode –
Press the button 
››› Fig. 120 5 to
switch air recirculation mode on or off. It is
switched on if the following symbol ap-
pears in the display .
Air recirculation mode prevents strong
odours or contaminated air from the outside
from entering in the vehicle, for example
when passing through a tunnel or in a traffic
jam.
With low outside temperatures, the air recir-
culation increases the effectiveness of the
heating system by heating the air inside the
vehicle rather than the air from outside.
With high outside temperatures, the air recir-
culation increases the effectiveness of the air
conditioning system by cooling the air inside
the vehicle rather than the ambient air. »

Operation
If the windscreen air output is on and air re-
circulation mode is pressed, this remains ac-
tive. 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 win-
dows 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 bar-
rier against impurities in the outside air, in-
cluding dust and pollen.
For the climate control system to work with
maximum efficiency, the pollution filter must
be replaced at the specified intervals in the
Maintenance Programme.
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 comfort for the vehicle occu-
pants 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 fol-
lowing reasons:
● The engine is not running.
● The A/C button is switched off.
● The outside temperature is lower than ap-
proximately +3 °C (+37 °F).
● 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 specialised work-
shop. CAUTION
● If you suspect that the air conditioner is
damaged, switch it off with the A/C button to
prevent further damage and have it checked
by a specialised workshop.
● Repairs to the air conditioner require spe-
cialist knowledge and special tools. There-
fore, we recommend you to take the vehicle
to a specialised workshop. Note
● If the humidity and temperature outside the
vehicle are high, condensation can drip off
the evaporator in the cooling system and
form a pool underneath the vehicle. This is
normal and does not indicate a leak.
● Keep the air intake slots in front of the
windscreen free of snow, ice and leaves to en-
sure heating and cooling are not impaired,
and to prevent the windows from misting
over.
● The air from the vents flows through the ve-
hicle interior and is extracted by slots de-
signed for this purpose. Therefore, do not
cover these slots with items of clothing or
other objects.
● The air conditioner operates most effective-
ly 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 condition-
ing system leaves residue on the evaporator,
producing a permanent unpleasant odour.
● It is advisable to turn on the air condition-
ing at least once a month, to lubricate the
system gaskets and prevent leaks. If a de-
crease in the cooling capacity is detected, a
Technical Service should be consulted to
check the system. 116

Care and maintenance
– If this does not provide satisfactory results,
use a special solvent-free plastic cleaning
product. WARNING
Never clean the dash panel and the airbag
module surface with cleaners containing sol-
vents. Solvents cause the surface to become
porous. If the airbag triggered, plastic parts
could become detached and cause injuries. CAUTION
Cleaning products which contain solvents will
damage the material. Wooden trim cleaning*
–
Clean the wooden trim with a water-mois-
tened clean cloth.
– If this does not provide satisfactory results,
use a gentle
soap solution. CAUTION
Cleaning products which contain solvents will
damage the material. Cleaning the radio and climate
controls
To clean the radio and/or climate controls,
use a soft damp cloth. For more resistant dirt,
a neutral soap solution may be used.
Seat belts cleaning A dirty belt may not work properly. Check all
seat belts regularly and keep them clean.
Seat belts cleaning
– Pull the dirty seat belt right out and unroll
it.
– Clean dirty seat belts with a gentle
soap
so lution.
– A
llow it to dry.
– Do not roll the seat belt up until it is dry.
If large stains form on the belts, the automat-
ic belt retractor will not work correctly. WARNING
● Do not use chemical cleaning agents on the
seat belts, as this can impair the strength of
the webbing. Ensure that seat belts do not
come into contact with corrosive fluids.
● Check the condition of the seat belts at reg-
ular intervals. If you notice that the belt web-
bing, fittings, retractor mechanism or buckle of any of the belts is damaged, the belt must
be replaced by a specialised workshop.
●
Do not attempt to repair a damaged seat
belt yourself. The seat belts must not be re-
moved or modified in any way. CAUTION
After cleaning, allow seat belts to dry com-
pletely before rolling them up. Otherwise, the
belt retractors could become damaged. 157
