Solution

1. Preparation

Tools Required: Lint-free cloth or paper towel
Ensure the car is parked on a level surface and the engine is off for accurate reading.

2. Check Oil Level

Remove the dipstick and wipe it clean as previously described.
Reinsert the dipstick completely back into the tube.
Pull it out again and examine the oil level on the dipstick.
- The oil level should be between the minimum and maximum marks.
- If the oil level is below the minimum mark, it needs to be topped up.

3. Top Up Oil (if necessary)

Tools Required: Funnel, clean oil (appropriate grade as per manufacturer specifications)
Remove the oil filler cap (located on the engine cover).
Using a funnel, pour the recommended oil into the engine gradually.
Recheck the oil level with the dipstick after adding oil to ensure it is within the correct range.
Replace the oil filler cap securely.
