REMOVAL

WARNING: On vehicles equipped with the high voltage system, you must thoroughly read and follow all High Voltage Safety procedures. In addition, before performing any diagnostic or service procedure near a high voltage component, you must perform the High Voltage Power Down. Failure to follow these instructions may result in possible serious or fatal injury

WARNING: Refer to the applicable warnings and cautions for this system before performing the following operation Warning and Caution . Failure to follow the warnings and cautions may result in possible serious or fatal injury.

CAUTION: Polyalkylene Glycol (PAG) oil can contaminate the refrigerant system of a Hybrid Electric Vehicle (HEV) and lead to A/C system damage and failure. If the refrigerant recovery/recycling and charging equipment was last used on a non-HEV model, flush the hoses of the equipment with a solvent approved by the equipment manufacturer before using the equipment on an HEV model, or use refrigerant recovery/recycling and charging equipment designated only for HEV models by your service facility. See the operating instructions supplied by the equipment manufacturer for proper use and care of the refrigerant recovery/recycling and charging equipment.

NOTE: The A/C liquid line is serviced in two sections. The front section connects between the A/C condenser and the receiver/drier. The rear section connects between the receiver/drier and the A/C expansion valve. On models equipped with the rear heating-A/C system, the rear section of the A/C liquid line also includes an extension tube that connects the liquid line to the underbody lines.
