I cannot get the Autofocus to work with a Canon EF 1.4X III Extender and a Canon EF 100-400 4.5-5.6L

Anyone know if the Autofocus will work with a Canon EF 1.4X III extender and a Canon EF 100-400 4.5-5.6L lens on a T3i? The compatibility chart says they will work together, but my T3i switches to manual no matter what I do.
