WARNINGDanger due to refrigerant coming out under pressure. Danger of frost bite to skin and other parts of the body. Extract the refrigerant and immediately open the refrigerant circuit after that. If the refrigerant was extracted more than 10 minutes in the past and the refrigerant circuit was not opened, extract the refrigerant again. Pressure in the refrigerant circuit is caused by evaporation.

Note. Refrigerant must be extracted before hand using ROB 134 APF. The previously used service stations can still be used. To prevent the entry of dampness all components of the refrigerant circuit which have been opened must be sealed with suitable plugs. The color coding of refrigerant circuit O-rings with R134a has been discontinued. Colored and black O-rings are used. Under certain conditions, the reservoir and the dryer/dryer bag does not need to be replaced each time the refrigerant circuit is opened. Refer to NOT REPLACING RESERVOIR/FLUID RESERVOIR OR DRYER BAG/CARTRIDGE, CONDITIONS . All safety precautions regarding performing repairs on vehicles with air conditioning and working with refrigerant. Refer to A/C SYSTEM AND REFRIGERANT R134A, SAFETY PRECAUTIONS . Information on tools for repairs in vehicles with climate control system can be found in SPECIAL TOOLS When filling and emptying with coolant, the heater and A/C unit refrigerant cut-off valve -N541- and the high voltage battery heater core refrigerant cut-off valve -N542- must be open. Use a voltage of 12 V for the shut-off valves when filling and emptying with coolant.
