To change temperature display from F to C, press the "temp +" button while
holding the "air recirculation" button.
To change from miles to kilometers as well as all the trip computer display
units, you'll need to find someone with a VAG-COM tool or make a trip to
your local Audi dealer in order to recode the Instrumentation from "USA" to
"Canada". Unfortunately, when you do this, your date display is going to
get messed up. As far as I know, there is no fix for this though. :-(
