First, make sure you have the CODE card for the radio if you still have the OEM radio. The dealership has a charging system that is hooked up to the jumper terminals under the hood to keep the CODE, radio stations, windows buttons and dash clock going.
Second, clean out the crap from the trunk.

Use the 13mm socket and extension to undo the battery hold down.

Use the socket to loosen the NEG termimal.

There's not enough clearance to use the socket on the POS terminal, so use the open wrench. I used a vice grip to keep the cable from twisting and rotating.

With the terminals clear, lift up the battery handles and pull it out. Warning, it's very heavy and could possibly have dried chemicals underneath, so be careful.

As you can see, the battery left some chemical residue, which includes battery acid.

First, use a shop vac to clean it out.

For what ever's left, you need to neutralize the acid. With some baking powder and water, mix up a thick paste and use a paint brush to apply it to the battery tray. The soda will neutralize the acid residue.

Wipe out the area with a clean towel.
Installation is the reverse of removal.
When replacing the battery, make sure you hook up the battery vent tube. The tube routes combustible gas from the batter to outside the car.

The battery I purchased didn't have the vent tube outlet in the same position as the OEM battery, so with some tubing, I re-routed it to fit.
