They don't specifically call out 5W-30, but this is in the manual on page 413 (or maybe +/- a page or so depending on the various revisions):
" The 20 in 0W-20 indicates the viscosity characteristic of the oil when
the oil is at high temperature. An oil with a higher viscosity (one with a
higher value) may be better suited if the vehicle is operated at high speeds, or under extreme load conditions."
Bolded the part about using a thicker oil for severe usage.
They also talk about 0W-20 being good for fuel economy 
"SAE 0W-20 is the best choice for
good fuel economy and good starting in cold weather."
