Switching the Climatronic temperature measuring unit
Press and hold the and buttons to switch the temperature display
between Celsius 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:
xThe engine is not running.
xThe fan is switched off.
xThe climate control fuse has blown.
xThe outside temperature is lower than approximately +3 °C (+38 °F).
xThe climate control system compressor has been temporarily switched off
because the engine coolant temperature is too high.
xAnother fault in the vehicle. Have the climate control system checked by
a qualified workshop.
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 underneath
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 Maintenance
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 stated
in the Service Schedule.
Note
The climate control system must left running for a few minutes to reach the
set temperature in the vehicle interior.
Note
After starting it, any residual humidity in the climate control system could
mist over the windscreen.
Note
The air from the vents flows through the passenger compartment and out
through the outlets below the rear window. Do not cover these outlets with
items of clothing or other objects.
