1. Park your vehicle in a safe location, turn off the engine, and engage the parking brake.
2. Open the hood of your BMW 5 Series using the hood release lever located in the driver's footwell.
3. Locate the battery in the engine bay. It is typically housed in a plastic cover with the BMW logo on it.
4. Remove the plastic cover by lifting it up and off the battery.
5. Identify the positive (+) and negative (-) terminals on the battery. The positive terminal is usually marked with a red cover or a plus (+) symbol, while the negative terminal is marked with a black cover or a minus (-) symbol.
6. Loosen the negative terminal bolt first, using the appropriate wrench or socket. Be careful not to let the wrench touch both terminals simultaneously, as this could create a short circuit.
7. Once the negative terminal is loosened, loosen the positive terminal bolt.
8. Lift the battery out of its compartment by carefully gripping it from the sides or using the designated handles if available.
9. Place the battery in a safe location and avoid contact with any metal surfaces to prevent short circuits.
10. If the battery tray has any corrosion, clean it with a wire brush and a mixture of baking soda and water. Rinse it thoroughly with water and let it dry completely.
11. When ready to reinstall the battery, carefully place it back into the battery compartment, ensuring proper alignment of the terminals.
12. Reattach the positive terminal bolt first, followed by the negative terminal bolt. Tighten the bolts firmly but do not over-tighten.
13. Replace the plastic battery cover and close the hood of your BMW 5 Series.
Now, the battery should be successfully removed and replaced in your BMW 5 Series. If you're installing a new battery, make sure it is the correct size, type, and voltage for your vehicle. It is recommended to consult your BMW owner's manual for the specific details and precautions related to battery replacement.
