Here are the items you'll need for this repair: T20 Torx Socket, 10-13mm socket, ratchet, socket extensions

Unclip the tabs that secure the floor mat. You only really have to undo these two. Then you can just fold it over and out of the way. This cover is where your battery is located. To get it out more easily, you'll want to lift up and snap this plastic cover off of the seat rail. Remove this T20 Torx screw here. We're going to do that with a Torx socket, ratchet, and extension. Remove the screw from the cover. Lift the cover up and away. Remove the negative side of the battery with a 10mm socket ratchet and extension. Remove the terminal from the battery and place it out of the way.

Remove this vent tube from the battery. Pinch the two tabs together, and lift up on the lid for the positive side. Loosen that 10mm as well. Disconnect the electrical connector here for this wire to the negative side of the battery, and lay the whole positive cable out of your way. Remove the 13mm bolt down here on the battery clamp with a 13mm socket, ratchet, and extension. Remove the bolt and the battery hold-down. Remove the battery from the vehicle.

Carefully lower your new battery into place. Reinstall the battery hold-down and your 13mm bolt. Tighten that bolt down with your socket/ratchet and extension. Reconnect the gray connector for the ground here. Lay the wire back in, and install the positive side of your battery terminal, which we'll then tighten down our 10mm socket/ratchet and extension. Keep in mind where your ground terminal is. Try to make sure that those don't accidentally connect while we're in here tightening this. Reconnect the cover. Reconnect the vent hose to the fitting on the side of the battery. This is very important because your battery does create some harmful gases as it charges and discharges. Having that line in place will keep all those fumes from building up inside of your vehicle.

Keep your keys handy in case this sets off your vehicle's car alarm, and reconnect the negative side of the battery. Tighten up the 10mm bolt. Reinstall the cover, and tighten down your T20 screw. Put the plastic cover back onto the seat rail. Snap it into place. Lay your floor mat back down. Reengage the hold downs.
