Hyundai Azera: Checking the engine oil level
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.
5. Pull the dipstick out again and check the level. The level should be between
F (Full) and L (Low).
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.
CAUTION - Replace engine oil
Do not overfill the engine oil. Engine damage may result.

If it is near or at L (Low), add enough oil to bring the level to F (Full). Do not overfill.
Use a funnel to help prevent oil from being spilled on engine components.
