The “Brake” light comes on when either the parking brake is on or there’s an issue with the brake pressurized circuit. Sometimes the Brake light stays on when the car is running due to a dirty or faulty switch at the parking brake. But you need to first check the braking system of the car to make sure there’s no problems, then look for a faulty parking brake switch. The “Maint Req’d” light is triggered by the car’s computer and the most common reason is oil change interval. Any decent oil change/lube shop can check the Maint light to see if your car is due for an oil change or if there’s something else triggering the Maint light. As jayeff mentions, the battery icon light indicates a charging system problem. But this light can also be triggered by the car’s computer so you might need to have a repair shop check the ECU codes and reset if necessary.
