Operational problems
If all the symbols on the display of the automatic air conditioning system flash for
approx. 15 seconds after switching on the ignition, then there is a fault in the system -
visit a specialist garage.
If the cooling system does not operate, the following faults may exist:
 the outside temperature is lower than +5°C,
 The compressor of the automatic air conditioning system was temporarily
switched off due to a too high temperature of the coolant,
 a blown fuse.
Check the fuse, replace it if necessary  page 177. If a blown fuse is not the source of
the fault, switch the Climatronic off and have it checked.
If the cooling capacity decreases, switch the Climatronic off and have it checked.
