Tip: if you turn off both the overheat protection and sentry mode, the phantom drain becomes 0%. I know this because I left my car idle for 2 months and it only lost 1% during that time.

It is fine to turn these off, other cars don't even have these and they are fine.

Don't you want the overheat protection at the end of a long drive? [edit: or is this just for the cabin temperature?]

I've also noticed a bit of drain when camping. It doesn't help that you often open/close the doors/trunk to access stuff ;)

My understanding is that it is for the cabin.

BTW, for the cabin I did two things:

- I installed a permanent shade for the sun roof. The sun roof is the stupidest thing ever, I hate it.

- In the summer, I usually put one of those shiny umbrellas to the front windshield when parked.

These two things alone reduce the cabin heat to an okay level.

I live in Calgary, overheat protection is only needed in one month in summer ;) I also installed the sun screen, the glass roof had a stress fracture and I didn't want to pay the $2k to fix it.
