  1. Make sure that the ignition of your Kia is turned off and the parking brakes are engaged. Open the hood and locate the battery on your Kia. On Kia vehicles, the battery is located in the engine compartment.
  2. On certain Kia models such as the Optima, the air assembly goes on top of the battery. This will need to be removed. Other Kia models such as Rio and Sedona may not have this cover. There are two screws that hold this cover in place that will need to be removed. Some models use plastic fasteners while others use 10 mm bolt to hold the air intake in place. Once the screws are removed lift the air intake assembly as shown in the video clip below.
  3. Disconnect the negative battery cable. You will need to loosen the nut on the negative terminal. This is a black cable. Near the negative battery post you will notice a minus symbol or negative symbol stamped on the battery. Once you loosen the bolt on the clamp the cable can be removed from the post. If the clamp does not come off easily, try twisting the clamp as you pull it away from the terminal. The next step is to disconnect the positive cable. The positive terminal will either have a plus sign near the post or the word positive printed. You can easily distinguish the positive battery post by the red plastic cover or the red cable.
  4. Now it is time to remove the old battery. Use both hands to lift up the old battery as car batteries are very heavy. Batteries may have a handle to help you with the removal. Carefully lift the old battery out of the battery tray and set it down on the ground. Once the old battery is removed, carefully install the new battery. Reinstall the battery bracket. Make sure that the battery does not move. Try to move the battery back and forth to ensure that the battery is secure.
  5. Before you reconnect the cables, clean the terminals using the battery post brush tool. Next, connect the positive cable and fasten the terminal bolt. Connect the negative battery terminal and tighten the bolt last. Start the car. Monitor lights on your instrument cluster. Confirm that there are no warning lights illuminated work and electronic controls work. Turn on the radio to confirm that it works, and if not, re-enter the security code that should be included in the documentation that came with the car.

If you have any warning lights on such as ABS or Electronic Stabil Stability Control (ESC) drive your Kia for a couple of minutes. Make sure to turn the steering wheel all the way to the left then all the way to the right. The engine needs to be running and the car has to be in Park.
