My car has been giving me heat out of the vents extremely fast in the morning. I timed it today, and I had warm air coming out of the vents within ten seconds of turning the engine on.

Is this an unadvertised feature? Typically a cabin pre-heater is standard on diesel vehicles, but my 35i seems to have one. I'm tempted to check out a parts diagram later today to verify.

Direct injected engines take forever to warm up, so it would make sense to me if this is true.
