Use only DH-PR compressor oil for this vehicle. Using PAG oil other than DH-PR compressor oil
can damage the A/C compressor.
Do not spill DH-PR compressor oil on the vehicle. A drop of compressor oil on the vehicle surface
can eat away at the paint. If oil gets on the vehicle, wipe it off immediately.
DH-PR compressor oil (PAG oil) has a higher moisture absorption efficiency than the previously
used mineral oil. If moisture mixes with the compressor oil, the refrigerant system could be
damaged.
Therefore, install caps immediately after using the compressor oil or removing refrigerant system
parts to prevent moisture absorption.
