The battery is weak. If you still have a Volvo battery installed, check the ground post. Usually it cracks and causes the battery to leak. So replace the battery and clean the terminals really good. If the corrosion went inside the insulator then you will need to replace the cables. The positive and ground cable come together as an "assembly" As for the warning lights, most likely the faults will be related to low supply voltage due to the control modules. Usually you will the SRS light come on, EPS warning message and so on. You should have all the control modules fault codes reset if the battery is faulty and you have replaced the battery. You should take it in to Volvo for that. Hope this helps and let me know what happens.
