A/C compressor OFF conditions ▶
Coolant temperature: over 115℃
Engine speed: over 4,500 rpm for more than 2 seconds
Engine speed: below 650 rpm
Maximum output due to abrupt acceleration
Excessive acceleration
Increased load during engine idling (to prevent the engine from shutting off)
Refrigerant pressure: over 32 bar or below 2 bar
