Solution

1. Preparation

Gather necessary tools: lint-free cloth or paper towel.
Ensure the vehicle is on a flat surface to obtain an accurate reading.

2. Check Engine Oil Level

Locate the Dipstick
- Open the hood and find the engine oil dipstick. It is usually near the front of the engine and has a colored handle.
Remove and Clean Dipstick
- Pull the dipstick out of the tube. Wipe the entire length of the dipstick with the lint-free cloth to remove any oil.
Reinsert Dipstick
- Insert the dipstick back into the tube fully until it is seated properly.
Read Oil Level
- Pull the dipstick out again and observe the oil level. The oil should be between the two markers (minimum and maximum).
Add Oil if Necessary
- If the oil level is below the minimum marker, add the appropriate type of engine oil through the oil filler cap.

3. Final Check

After adding oil, wait a few moments, recheck the level with the dipstick to ensure it is within the acceptable range.
