Air conditioning regular
operation In order to ensure continuously
efficient performance, it is
recommended that air conditioning
should be operated for a few minutes once a month, irrespective of the
weather and time of year.
Service
For optimal cooling performance, it is recommended to annually check the
climate control system, starting
three years after initial vehicle
registration, including:
■ functionality and pressure test
■ heating functionality
■ leakage check
■ check of drive belts■ cleaning of condenser and evaporator drainage
■ performance check
