- 1). Turn the Mazda 6's key in the ignition. Listen for the engine to crank. If you don't hear the engine crank, you probably have a dead battery.
- 2). Open the hood of your Mazda 6 and look over the battery terminals. Use a socket wrench to tighten the terminals if needed.
- 3). Take the battery terminals off of the battery and pour a little bit of soda onto them. Scrub the areas with a wire brush to take any corrosion off.
- 4). Use jumper cables and another car to jump-start the Mazda 6. Leave the car running for about 10 minutes to get the battery charged. If you smell something like rotten eggs coming from your battery, you will need to replace it.
- 5). Add one gallon of gasoline to your Mazda 6 and then try to start the car. If your gas gauge is broken, you could be out of fuel.
