Default 2013 GS coolant change?

I'm getting ready to change the coolant on my 2013 GS and was wondering the simplest way to do it. Any tricks or tips? Thanks!

Attached procedure from my bootleg manual. ($60 on ebay...and it's proven to be pretty useful, not quite as good as the old factory manuals, but good enough.)

you should leave the expansion bottle open and let it heat it up to temperature. It should self bleed the air... Then fill to level again. Havent done my GS but almost all newer generation cars are like that

Yeah it's not brakes. It's an open system and the air will self bleed. You just need to run it to operating temp and top off coolant as needed.
