The engine oil level warning light illuminates when the engine oil level should be checked.
If the warning light comes on, check the engine oil level as soon as possible and add engine oil as required.
Slowly pour the recommended oil little by little into a funnel. (Oil refill capacity : approximately 0.6 ~ 1.0 l)
Use only the specified engine oil. (Refer to "Recommended lubricants and capacities" in chapter 8.)
Do not overfill the engine oil to ensure the oil level is not above F mark on the dipstick.
✽ NOTICE
CAUTION
If the light comes on continuously after adding the engine oil and traveling approximately 50 km~100 km after the engine warms up, we recommend that the system be checked by an authorized Kia dealer.
Even if this light doesn't come on after the engine has started, the engine oil should be checked and supplied periodically.
