If it's anything like the YRV, then it's the door handle and the screw inside of the door puller. Then at the bottom of the trim there are 3 access holes where the bottom clips are. Your best using something like a Halfords laser trim removal tool, and you have to prise away the 3 bottom clips. Once they are done then you can work your way up pulling the trim to remove the other clips. On the YRV that caught me out is that the top of the trim is hindged where the side window is, and therefore once you are happy you have the remaining clips released, you will need to push the trim upwards for that bit to come off.
