How do you top up oil on a Honda CR-V 2004?

To top up oil on a 2004 Honda CR-V, first ensure the vehicle is on a level surface and the engine is off. Open the hood and locate the oil dipstick; remove it, wipe it clean, then reinsert and remove it again to check the oil level. If it's low, use an oil funnel to pour the recommended oil type (typically 5W-20) into the oil filler cap. Check the level again after adding oil to ensure it reaches the proper mark on the dipstick, and replace the dipstick and cap securely.
