Features & Controls Voltmeter (omoN) When your engine is running, this gage shows the condition of your charging system. When your engine is not running, but the ignition is on (in the Run position), the gage shows your battery's state of charge in DC volts. Readings between the red warning zones indicate the normal operating range. Readings in either red warning zone indicate a possible problem in the electrical system. Have your vehicle serviced immediately. Brake System Warning Light Your Pontiac's hydraulicbrake system is divided into two parts. If one part isn't working, the other part can still work and stop you. For good braking, though, you need both parts working well. If the warning light goeson, there could be a brake problem. Have your brake system inspected rightaway. This light should come on as you start the vehicle. If it doesn't come on then, have it fixed so it will be ready to warn you if there's a problem, This light will also come on when you set your parking brake, and will stay on if your parking brake doesn't release fully. If it stays onafter your parking brake is fully released, it means you have a brake problem.If the light comes on while driving, pull the road and off stop carefully. You may notice that the pedal is harder to push. Or, pedal the may go closer to the floor. It may take longer to stop.If the light is still on, have the vehicle towed for service.
