By pre-warming the engine, it eliminates the rough sounds and added stress associated with cold starts. At the same time, it channels warm air into living spaces, so you step into a ready-to-go interior even after long periods of freezing weather. When the engine is running, the system sustains a comfortable cabin temperature; when parked, it continues to maintain warmth for prolonged comfort.\u003c\/p\u003e \u003ch3\u003ePerformance you can trust in extreme cold\u003c\/h3\u003e\n\u003cp\u003eDesigned for harsh environments, Flow 5D operates reliably down to -45°C.
