Kia Optima: Checking the engine oil level

2.4 engine

2.0 engine
1. Be sure the vehicle is on level ground.
2. Start the engine and allow it to reach
normal operating temperature.
3. Turn the engine off and wait for a few
minutes (about 5 minutes) for the oil to
return to the oil pan.
4. Pull the dipstick out, wipe it clean, and
re-insert it fully.
WARNING - Radiator hose
Be very careful not to touch the radiator hose when checking or adding the engine oil as it may be hot enough to burn you.
5. Pull the dipstick out again and check the level. The level should be between F and L.
CAUTION
