Hi, it takes 2 CR2025 batteries.

I can send the instructions to you by mail
In the trunk.
check the trunk near the battery.
next to the spare tire in the trunk.
Yes. The battery's in the trunk under the floor of the trunk. Just lift it up and you will see the battery along with the spare.
If the battery was charged when you installed it, you do not have to drive the car at all. If not you should charge the battery and not use the cars alternator to charge it.
