Need some advice, instrument cluster

[Reecard]

Yesterday I installed a new stereo system in my X. My X did have the DSP, so I have a new head unit, amp and sub. I did use some factory wiring that we unplugged from the old head unit for amp trigger and few other things. Everything well fairly well and sounds great. In the process of the install, my battery went dead and we had to put a charger on the vehicle. When I started the car, I had a bunch of things showing up in the dash, i.e. dsc, brake, seat belt and ses. After moving the car most of these went away. But the seat belt light stays on along with the ses. And my turn signals work, but there is no indicators in the instrument cluster or high beam light. Do I need to unhook the battery to let things reset or is there something else that is the problem. Please help.
