Climatronic A/C System with Automatic Control
Climatronic A/C System with Automatic Control
• The vehicle has a Climatronic with 2-zone right/left temperature control or 4-zone right/left, front/rear temperature control.
• Pressing the button "AUTO" will reverse all settings which deviate from the automatic operation.
• In "A/C" mode only the A/C compressor is set to almost zero delivery. The heating and ventilation operation continues to be controlled electronically.
• If there is a deviation from the automatic operation before ignition is switched off, the selected functions remain permanently stored.
• Deviations from automatic operation, refer to respective operating instructions.
• If there is a malfunction in the system, first read the DTC memory with the Vehicle Diagnostic Tester in "Guided Fault Finding" function.
Hybrid vehicles have a high voltage system. Danger of electric shock! It will also be necessary to work on the high voltage system when performing the following procedures. Switch off the high voltage system.
• The refrigerant circuit should be flushed with refrigerant R134a:
• In the event of dirt or other contamination in the refrigerant circuit.
• If vacuum reading is not maintained on evacuating a leak-free refrigerant circuit (pressure build-up due to moisture in refrigerant circuit).
• If refrigerant circuit has been left open for longer than normal (for example, following an accident).
• If pressure and temperature measurements in the refrigerant circuit indicate the likelihood of moisture
• If it is not clear how much refrigerant oil is in the refrigerant circuit.
• The A/C compressor had to be replaced due to internal damage (for example, noise or no output).
