No, you are not doing damage with a caveat. What temperature are you operating in? If you are at 0 degrees F or lower you should only use 0W-30. Above that 10W-30 is ok. How do I know? I checked pages 319-320 of your owner’s manual.

I would just use the oil they call for. But you’re probably not doing damage.

I highly recommend using the oil weight the manufacturer suggests in the owners manual and/or updated service bulletins.
It probably won't do much damage since the weights are so close, but I personally wouldn't risk it.
