Where are the release catches to tilt front seat to get at battery?

I have made several attempts to tilt the front passenger seat forward in my Citroen X Zara Picaso so that I can charge the battery. Where exactly will I find the release catch to tilt the seat. And if I connect a battery charger to charge the battery from flat, will it harm any other components, or, would it be safer to have a tow-start?
