Heated Seats always ON setting?
 

Can you set heated seat always ON when you switch on the car? I had Audi A7 in the past and it saves the last used heated seat setting in memory, so that when you switch on the car it always use that setting.

Does anyone know if this is possible in Cayenne?

I don't think it is possible. On our old Lexus you could set the seats to "auto" and it would heat or ventilate the seats as needed. It really is too bad a similar feature doesn't exist on these cars.

So true and I also couldn’t find a way to modify the default car settings under different drive modes, for eg. i want my suspensions to be in low setting in sports mode keeping everything as it is. But when I do it manually it just keeps car low for e drive and even for hybrid setting. Weird.

You could probably program it to remember for more than 1 hour, as I believe it's the default. That requires an up to date PIWIS.
In the '24 model, not even the steering wheel "remembers" the ON setting as it was with all models prior, cayenne or not. Maybe someone forgot to code that line.

My RS6 remember the steering wheel and seat heating setting last used. It's so convenient in the winter, I just start the car and everything is ready to go. I like how I can start the car while I get my son loaded in. By the time I get to the drivers seat, everything is nice and toasty already.

I don't think the Cayenne does that. Do you have Porsche Connect? With my eHybrid I can tell it to precondition the Cayenne for interior temp and seat heating. But this might just be for the eHybrid models. I have it set to precondition and finish charging with the departure timer. If I am off charge I can still tell it to precondition through the app.
