Heating, Ventilation and Air conditioning
Keep the air vents in front of the windscreen free of snow, ice and leaves to
ens ur
e heating and cooling are not impaired and to prevent the windows
from misting over.
Adjustment for safer driving
When the air conditioning is switched on, the temperature and the air hu-
midity in the vehicle interior drop. Hence, when the outside air humidity is
high, the windows do not mist over and comfort for the vehicle occupants is
improved:
With Climatic
● Disable air recirculation mode ⇒  pag
e 161.
● Set the fan to setting 1 or 2.
● Turn the temperature control to the centre position.
● Open the air outlets in the dash panel ⇒ pag
e 161.
● Turn the air distribution control to the required position.
● Press the AC button to turn on cooling. The button will light up.
With C lim

atronic
● Press the AUTO button.
● Set the temperature to +22°C (+72°F).
● Open the air outlets in the dash panel ⇒ pag
e 161.
Switching the Climatronic temperature measuring unit
Press and hold the AC and
AUT
O buttons to switch the temperature display
between C el

sius and Fahrenheit.
Heat
The maximum heat output required to defrost windows quickly is only avail-
able when the engine has reached its normal running temperature.
The air conditioning system does not switch on
If the air conditioning system cannot be switched on, this may be caused by
the following: ●
The engine is not running.
● The fan i

s switched off.
● The climate control fuse has blown.
● The outside temperature is lower than approximately +3°C (+38°F).
● The climate control system compressor has been temporarily switched
off becau
se the engine coolant temperature is too high.
● Another fault in the vehicle. Have the climate control system checked by
a Tec
hnical Service.
Things to 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 under-
neath the vehicle. This is normal and does not indicate a leak!
Dust and pollen filter
The dust and pollen filter with its activated charcoal cartridge serves as a
barrier against impurities in the ambient air.
For the climate control system to work with maximum efficiency, the dust
and pollen filter must be replaced at the intervals specified in the Mainte-
nance Programme.
If the filter loses efficiency prematurely due to use in areas with very high
levels of air pollution, the filter must be changed more frequently than sta-
ted in the Service Schedule. Note
● The climate control system must left running for a few minutes to reach
the set t

emperature in the vehicle interior.
● After starting it, any residual humidity in the climate control system
coul
d mist over the windscreen.
● The air from the vents flows through the passenger compartment and
out through the outl
ets below the rear window. Do not cover these outlets
with items of clothing or other objects. 
