Make sure you latch the top to the windshield before attempting to pop in the buttresses. If you attempt to do "all the outside stuff first" before closing the latch inside the car, it doesn't work well at all. Top raising sequence:
- Open trunk.
- Raise top.
- Latch center latch to windshield.
- Close trunk.
- Close buttresses.
Gotta do it int that order.
