So somehow I think my trip computer got set to Celcius or something because it always reads something funny. Not sure how to switch it back any adivce.

 

is your speedo reading as kilometre's? try swtiching back and forth between Metric and Imperial

 

i believe with key in on position......pump gas pedal 5 or 6 times to change the language....or more......not exactly sure how many pumps....or try holding the trip reset button in till it flashs to english....

I had to change it in my silverado....but i forget which method it is....srry

 

Too bad its not as easy as the GTO just hit a button lol

 

Lol I'll have to try all of those. I have no clue how it got switched I think I've tried the reset button but never hurts to try again.
