This looks like a tech doing it with special tools. Not sure if it is the same year. I think you will be fine with my recommendations. Just get it warm enough for the temp gauge to read halfway. Do it a couple of times. When it runs cooler then drive it a little further.
You can't do it too much, unless the bottle coolant level stays the same. Run the heater on max heat to make sure you get any air out of the heater core as well.
DO NOT run it with the cap loose or removed. The air pocket could hit you with some very hot coolant or steam. Always check it cold. Wait at least 30 minutes at the very minimum, preferrably longer.
