Using radio/cd with no key?
It turns off when taking out the key but on again when I push on the volume button. Is it normal? I know I can't do this on other cars. I kind of like it, though

I agree MarkL. Simple trade: Use resources=need to replace resources. Any use (including the temp sensor fan in the overhead console and the ROM heartbeat in the ECU) uses power and drains the battery.
My bet is if you parked your car in the garage and don't touch it for 6 months, you'll have a dead battery.
I'm not into 3 minute headlamp shutoff delays for the same reason.

MR-BOB is correct. The parasitic load that any vehicle can tolerate is not linear. It depends on time and temperature.
Given enough time sitting in your garage drawing current your battery will eventually be exhausted.

What E 4.3 meant, me thinks, was that if you forget to switch the radio off and leave the car unattended for a few hours (or even overnigt), the battery will still be very much alive.
