I seldom do this, but I just checked in the owner's manual!
It says...
Park on level surface
Run engine until at operating temperature
Turn off engine and wait more than 10 minutes for oil to drain back in to the oil pan
Remove dipstick, clean and re-insert
Remove dipstick and check level is between H & L
Top up if below L, do not overfill.
Personally, I check the level when it's fully cold - first thing in the morning.
