Pull the dipstick out and wipe it clean with a lint-free cloth.
Reinsert the dipstick fully and remove it again to check the oil level.
Ensure the oil level is between the minimum and maximum marks on the dipstick.

4. Add Oil (if necessary)

If the oil level is low, select the appropriate oil type as specified in the owner's manual.
Remove the oil filler cap, typically located near the engine cover.
Use a funnel to pour oil slowly, checking the level frequently.
