It looks like you are having a problem with your park brake warning system, if the park brake pedal is not returning to the full up position, the warning will stay on. If that does not fix it you have to look at the park brake assembly and see it the switch is ok and properly mounted. If those are all ok, you may need to get a shop manual and try to trace the wires and diagnose the system. The warning should not come on if the brake fluid is low. You should check you owners manual to double check the definition of the warnings that are coming on.

I own the same vehicle and it started doing then when the brake pads were low.
