Refrigerant R1234YF Capacities

NOTE:

When charging the high-pressure side of refrigerant circuits, always use maximum amount of refrigerant (some of the refrigerant remains in the charging hoses).

The specified capacities for refrigerant R1234yf apply if no other different specifications are given, also for the "S" and "RS" versions of this vehicle model.

Make sure the A/C Service Station is on the same level as the vehicle (maximum difference: 50 cm) when charging the refrigerant circuit. If a difference in height is too large, a difference between the amount of refrigerant displayed on the service station and the actual amount filled in the circuit may result (depending on the version of the A/C Service Station). The filling precision of the A/C service station may change.

The capacities for the refrigerant R1234yf and the corresponding refrigerant oil are no longer in the main repair information, but rather in this information. Refer to TECHNICAL DATA  .

Pay attention to the different capacities for refrigerant R134a in vehicles without a rear A/C unit (with an evaporator) and in vehicles with a high-voltage system (with two evaporators).

For additional information on evacuating and charging the refrigerant circuit, refer to appropriate service information. .

-- Discharge, evacuate and charge the refrigerant circuit. Refer to appropriate service information. .

-- Operate the A/C system after charging the refrigerant circuit. Refer to A/C SYSTEM, STARTING OPERATION AFTER FILLING REFRIGERANT CIRCUIT .
