If the warning light is on then that probably means that there is a leak. If the bags are inflated it is safe but when they blow out you are in trouble. If there is a leak, the compressor is working overtime to keep the bags full and will eventially burn up and stop working. It's dangerous to drive with any of the bags deflated so it has to be repaired as soon as possible.
Your question is too broad. Is the car riding low? Just front, or just back or both? to high front and back
