Your owner's manual has a chart showing what pressures to run for a given vehicle trim and tire/wheel size. My manual has this on page 351 but yours will likely be on a different page nearby.
According to my manual (and again, yours will likely be different, my manual is some weird one-off print) :
for 20" summer tires on a base/S, 31/37 comfort or 34/44 full load
for 20" summer tires on a 4/4S, comfort goes up to 31/39 with full load remaining at 34/44
Your door sticker will show the full load pressures.
Your MFD will show the target pressures for the given configuration you have selected.
Obviously, you can play with these pressures, +/- around 3psi, with little to no detrimental effect. A higher pressure will yield marginally better mileage but a more jarring ride. A lower pressure will increase tire wear and marginally lower your mileage.

Partial/comfort load is what you run if you aren't driving 160+ mph and want a modicum of comfort.
The manual should have these pressures listed under the tire pressure section. Go to the index at the back and look up tire pressures. Should be a couple hundred pages in, for whatever reason the number 268 is stuck in my head for that.
You can also go through the MFD to toggle the TPMS to shoot for comfort (aka partial) or full load. In the tire pressure menu while at a standstill push the select button. Check 'partial load' or 'comfort' or uncheck 'full load' -- can't remember the checkbox, but you want to tell the car that you want comfort or DON'T want full load. Then look at your target pressures.

Full load is what you run to achieve the actual top speed of these vehicles because it significantly reduces rolling resistance.
