Sounds like you are likely driving in heavy traffic all the time.
Mine is 6.5 L / 100km on 70% highway driving. Frankly, quite impressed as my previous 1.5 L (smaller engine = usually better FC) vios couldn't manage that on the same route, best I could ever get was 7.0 L / 100km. Was expecting the 2.0L M3 to consume more petrol given it is a larger engine so am pleasantly surprised.

Sending for first 1k service tmr so am hoping it will improve more given it has now properly burned in.

Any CKD High Spec owners or CBU owners here who have applied Llumar Crystal 6? Does it impact your GPS ability to locate your position? I sent my car in today for 1k service and the Bermaz SC verified they felt something not right with my GPS - and tentatively suspect the tint. I need to bring the car back, but am reluctant coz they may have to disassemble the dashboard etc.

Nope - no such feature on CKD.

It is normal. I think I saw something in the manual saying that it is the car's catalytic converter warming up the engine to optimize fuel efficiency from cold start. I remember reading that it is safe to start anyway without waiting. You will notice it only happens after overnight or when your car has been left in a shady place for many hours.

Indoor temperature gauge should be on the right hand side display panel. I think it is switched on by default, else you might be able to activate it in the settings - I don't recall exactly where but I do remember the option of choosing between Celsius and Fahrenheit.
As for console, I'm afraid no - although you could set it to the average FC setting.... all other 'drive-related' information will only be on the right hand display panel, controllable by the 'info' up-and-down button on the steering wheel...
