• Symbols on the information label -A- indicate the dangers which may occur when handling refrigerant and/or when working on the refrigerant circuit.
• Norms and standards can also be stated, such as the valid SAE standards defined in the USA. The SAE J639 describes the safety precautions for A/C systems in passenger vehicles. The SAE J842 explains that only approved components and materials may be used for refrigerant R1234yf, and SAE J2845 says that only trained and certified technicians may perform repair and service procedures on the A/C system refrigerant circuit.
• Depending on the version and the vehicle date of manufacture, the GWP value (global warming potential) for the refrigerant used may also be specified. Refer to REFRIGERANT R1234YF, ENVIRONMENTAL INFORMATION .
• Depending on the version and the vehicle date of manufacture there maybe be a CO2 equivalent "CO₂ eq" of R1234yf given on the information label -A-. The value states what influence the quantity of R1234yf filled in this refrigerant circuit has on the Earth's atmosphere, if it completely escapes. The influence of carbon dioxide ("CO₂ ") is used here as a reference value. Refer to REFRIGERANT R1234YF, ENVIRONMENTAL INFORMATION .
• The capacities and the type of refrigerant oil specified on the information label -A- show the status at the time of vehicle production. The current applicable values are those in the vehicle-specific Service Information. Refer to Technical Data (vehicle-specific Service Information).

Specifies the type of refrigerant and designated capacity. Refer to Technical Data (vehicle-specific Service Information).
