TEST CONDITION Testing must be performed as per the following:

Vehicle condition | Indoors or in the shade (in a well‐ventilated place)
Doors | Closed
Door windows | Open
Hood | Open
Temperature control switch or dial | Maximum cold
Mode switch | (Ventilation) set
Intake switch | (Recirculation) set
Fan (blower) speed | Maximum speed set
Engine speed | Idle speed
Operate the air conditioning system for 10 minutes before taking measurements.
