When does the parking brake need to be disengaged?
Sometimes I just get in the car and drive away. Other times it won't move until I manually disengage the parking brake.
Why?

Personally, I manually engage it and manually disengage it since I want the car resting on the parking brake, not the transmission pawl.

I've never been in the habit of using the parking brake with automatics. Maybe I'll try it. This is my first car with an electric parking brake.

Unless I am on completely level ground, I always use it.
1. Foot brake engaged, put car in Neutral.
2. Engage parking brake, release foot brake.
3. When car stops and rests fully on the parking brake, put car in Park.
To drive off:
1. Foot brake engaged (I use left foot for this), put car in gear.
2. Release parking brake.
3. Release foot brake and drive off.
I always want the weight of the car resting on the parking brake, and not the transmission pawl. If you hear a clunk when you get out of Park, your transmission pawl was holding the weight of the car, not the brake.

It's amazing how many people just use the transmission to park the car rather than the brake--saving pressure on the transmission. When parking on a hill, apply the parking brake while the car is still in gear, then shift to the park position on the tranny. When leaving, start car, put in gear, THEN release the parking brake.

I guess it helps that I drove manual transmission cars for forty years. But my dad was a “Buick Man”, and if he ever caught you parking the Electra without going through the sequence, you were taking the BMT for a week. (BMT was either a subway line in NYC, or BY My Thumb, as circumstances required.)

100% it's because of the seatbelt. I'm in the habit of always engaging the electronic parking break. However, I'm not in the habit of disengaging the parking brake nor putting on my seatbelt right away. Every time I forget to put on my seatbelt and put the car in D/S and gas it, the parking brake doesn't disengage. Only if my seltbelt is on and start driving will the parking brake disengage.

I tried it this morning and the brake did not release automatically with my seatbelt on when I put the car in R. But I see the manual says I also have to press the gas peddle somewhat to release it, which I don't think I did. When I put the car in R and the brake didn't release, I think I just released it manually. I'll have to try it again.
I think I'd like to try to get in the habit of using it. The only thing that concerns me is the power draw. It uses battery power to maintain the brake. As if this car doesn't demand enough from the battery already.

Yes, my answer is right there in the manual:
You can release the parking brake automatically when:
• You are wearing the driver’s seat belt.
• The engine is running.
• The transmission is not in (P or (N.
The manual is silent about the sequencing of the automatic brake and the transmission when parking. My routine is to turn off the engine while still in drive, with my foot on the brake pedal, without ever pushing the Park button. Ideally, the system is smart enough to engage the brake before the parking pawl.
@Madd Dog : My daddy gave me sort of the opposite advice. He told me when parking on a hill to leave the transmission in first gear to provide additional braking power.

Tried it again and it works as advertised. The first time I tried it, it lurched when I hit the gas but I found you just have to barely touch the gas to get it to disengage.

This never works for me. I need to manually disengage the parking brake also to be able to have the car move. Somewhat annoying.

I “manually disengage” the parking brake. Have done so for half a century. It never seemed like a chore to me.
I ‘manually’ engage and disengage the parking brake so I can decide how it is to be used.

I still don't like the idea that the brake is using battery power to remain engaged. I'm sure it's minimal but how minimal? I have no idea.
