-- Coat the O-ring seals lightly with refrigerant oil before installing. Refer to REFRIGERANT CIRCUIT SEALS .

-- Make sure the retaining plate -D- fits correctly on the connection pipes -C and E- leading to the evaporator.

-- Tighten the bolts -G-.

• Tightening specification: 10 Nm.

-- Install the refrigerant line with inner heat exchanger. Refer to REFRIGERANT LINES WITH INNER HEAT EXCHANGER, REMOVING AND INSTALLING .

-- Evacuate and charge the refrigerant circuit. Refer to REFRIGERANT CIRCUIT .

On Vehicles with a High Voltage System (Hybrid Vehicles)

-- Visually inspect the high voltage components -D- and high voltage cables -E- after completing the work procedures and before installing the plenum chamber cover -B-. Refer to WARNINGS WHEN WORKING ON VEHICLES WITH HIGH VOLTAGE SYSTEM .

-- Electrical connections and routing. Refer to Wiring Diagram.

-- Energize the power supply to the high voltage system. Refer to WARNINGS WHEN WORKING ON VEHICLES WITH HIGH VOLTAGE SYSTEM .

All Vehicles

-- Install the remaining removed components.

-- Turn on the ignition.

-- Check the DTC memory for the Climatronic Control Module -- display and control head and erase any displayed malfunctions, if necessary using the Vehicle Diagnostic Tester in the "Guided Fault Finding" function.
