Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to ensure safety during the procedure.

2. Check and Top Off Engine Oil

Sub-steps:
- Remove the oil filler cap.
- Use a clean funnel to add the appropriate type of oil if the level is low (consult the owner's manual for oil specifications).
- Replace the oil filler cap securely.

3. Replace Oil Filter

Sub-steps:
- Locate the oil filter, typically situated on the side of the motor.
- Use an oil filter wrench to remove the old oil filter (be prepared for some oil spillage).
- Apply a small amount of new oil to the rubber seal of the new filter.
- Install the new oil filter by hand, ensuring it is snug but not overtightened.

4. Change Engine Oil

Sub-steps:
- Place an oil drain pan under the oil pan.
- Remove the drain plug using a socket set and allow the used oil to drain completely.
- Replace the drain plug and tighten it to the manufacturer's torque specifications (typically around 25-30 Nm, consult the service manual).
- Refill the engine with new oil through the oil filler cap using the correct amount as specified in the owner's manual.

5. Test Oil Pressure

Sub-steps:
- Reconnect the battery.
- Start the vehicle and let it idle.
- Monitor the oil pressure using the onboard system or a manual gauge to ensure it is at the correct level.
