2. Pull the hood release under the dashboard. Go to the front of the vehicle, release the hood latch, and lift up the hood. Secure the hood with the hood rod or ensure the hood stays up on its own. 

    

3. Locate the battery and lift up or remove the cover if your battery has one. 

    

4. Use a 10mm wrench to loosen the nut on the negative (-) battery terminal. Disconnect the negative battery terminal. 
5. Loosen the 10mm nut on the positive battery terminal. Disconnect the positive battery terminal. 
6. Remove the 13mm bolt for the battery bracket. Remove the bracket on the side of the battery. Be careful to not drop the bracket. 
7. Carefully remove the old battery from the car. Batteries are heavy, get someone to help you remove the old battery. 
8. Clean the battery tray area and place the new battery in the tray.
