No, 12v does not need to be maintained unless you want to keep your settings. Removing the battery powers off everything electrical, so the alarm would not work, until you put a new battery in.

After you replace the battery you will need to:

Enter your radio code

Roll your windows the whole way up, then release the buttons and push again for a second or so.

Reset your egas. Without touching gas pedal, turn key on for a minute or so, then turn off for more than 10 seconds.

Wal Mart has the correct battery.

I picked up an Energizer bunny battery from Sams.

Don't forget to leave your frunk open! I place a piece of styrofoam OVER the front latch so it cannot shut. Also, that reminds me to re-connect the battery.

Don't be afraid to disconnect it/replace it. Just do it right! I have disconnected my battery at least 30 times doing "upgrades".

@Paul - Didn't know about the eGas thing….does it reset itself by itself? Because I have not been performing that particular step. Any downside or does egas system re-adjust?

Learn something new everyday!

Nope. Just need to drive it about 60 miles or so for it to reprogram to your driving style.

I did a write-up on the battery that should be used in our cars. Best one out there is the EverStart® Battery MAXX-94R which is carried at Wal-Mart.
