Capacity is 0.6qts. Not sure why the manual specifies to remove the front bottom cover... only removing or pulling back the rectangular cover is needed. The fill bolt is pretty tight loosening for the first time--you may need a breaker bar.
Also: for MY2020-2021, anytime you remove the rectangular bottom cover, look for any signs of front axle disconnect actuator leak (located on driver's side, left of bottom cover) as that will be front differential oil which has a relatively small capacity to begin with.
If you ever replace the halfshaft speed sensor (located on the front differential), you will spill front differential oil and need to top it off.
