This is also something that bothers me. Is there a way to get any climate functions to automatically turn on when the engine is started.

It would be really great if I could get the max defrost and seat heaters to turn on when I use the app to remote start my car in the winter - and the coolers/ac in the summer (like in my other cars).

residual in my car is the menu button on the left (it also says "rest" underneath "menu")
But this button uses my hybrid battery to heat the car

Thanks. Not that it really matters but do you (or anyone else) know why? Seems odd given the fact that remote start value is significantly diminished without this capability (at least IMO).

MB realized that so they started offering that feature on the new models such as a W214 E-Class through routines.

Nope, that's Auxiliary Heating, an independent fuel powered heating to work when the engine is off.
The Residual Heating is a less effective system that uses the coolant residual temperature to maintain the heating, limited to 30 seconds and the point where coolant is no longer hot enough to provide any heating at all. It is recognised by the lettering "REST" on the A/C switch.

Thank you for the correction, I appreciate it. I thought it is just the same thing since it seems to be in the same place as the reset button just an icon instead.

You are very welcome.
And I correct myself... Where it says 30 seconds, I meant 30 minutes. Sorry for the mistake

I see, thank you, 30 minutes makes sense.
