Welcome onboard. The battery sign in the drivers foot well. If you open the cover you will find a link that can be connected to in the event you have a totally flat battery. In this situation you will not be able to open the front bonnet to get to the battery, its electrically operated. I carry a small jumper pack in one of the storage compartments either side of the engine. So if I do get a flat I can then use jumper pack to open bonnet and then jump car or charge battery.
There is manual cable in the wheel arch but it meant to be a pain to get to.
