For some reason my late '90s Park Avenue has changed from reporting thermometer readings in farenheit to reporting them in centigrade. How can I switch the displays back to farenheit? ---

Read the owner’s manual. If you can’t find it there, call the dealer service department and ask them. ---

Just find and push the button again and it will change. If this vehicle has a ‘drivers information center’ you will likely find your answer there. ---

Why not just leave it there for a while. Take it as an opportunity to get to know centigrade / Celsius measurements. 100= water boiling, 30-60 typical laundry temperature, 37= human normal body temp, 30= typical US city in the summer, 20= comfy room temperature, 0= water freezing, -20= stay home unless you’re a Minnesotan. ---

In case you can’t find the button, here is a quick conversion: Farenheit = 9/5(Centigrade + 40) - 40 To convert the other way, the quick formula is: Centigrade = 5/9(Farenheit + 40) - 40 The distance from freezing to boiling on the Centigrade scale is 100 - 0 = 100 The distance from freezing to boiling on the Farenheit scale is 212 - 32 = 180 The ratio of the Farenheit scale to the Centigrade scale is 180/100 = 9/5 The ratio of the Centigrade scale to the Farenheit scale is 100/180 = 5/9 -40 C = - 40 F. This is why the formulae work. You now have 3 choices: 1. Find the button 2. Practice mentally converting from Centigrade to Farenheit and you’ll be so proficient in a week or so that you won’t need to look for the button 3. Move to the South Pole in a region where the temperature is always -40 on either scale (Of course, this will give you other things to worry about–I’ve heard Penquins may eat electrical wiring) ---

If you can’t find your owner’s manual or can’t find the information you need in it, try this link. [http://www.ebookspdf.com/search/SERVICE+MANUAL+BUICK+park+avenue+19K+park+avenue+1](http://www.ebookspdf.com/search/SERVICE+MANUAL+BUICK+park+avenue+19K+park+avenue+1) If you can actually download manuals there – and it sounds like you can – you should probably be able to search for centigrade or temperature and find the instructions you want. ---

Does your owner’s manual really not cover this?
