Procedure 

• Depending on the A/C Service Station used, changes to the work procedure may be needed. Pay attention to the Owner's Manual. Refer to Owner's Manual.

Vehicles with High-Voltage System

Continuation for all vehicles

-- Switch off the ignition.

-- Remove the caps from the service connections. Refer to Refrigerant Circuit .

-- Check the refrigerant circuit service connections for debris and corrosion and if necessary clean.

TIP

• Dirt or a rough surface on the service connections due to corrosion can cause seal damage, which can then cause premature failure of the quick-release couplings.

-- Connect the quick-release couplings to the service connections (low pressure and high pressure). Do not screw in the hand wheels of the quick-release couplings.
