Another way is to take out the glove box, have a friend or family member ride with you to check while you drive down a bumpy road in the cold.
Being a firefighter and making lots of accident scenes, I would suggest the latter, hahaha! Believe it or not, I have had to explain the difference between cruise control and auto-pilot to more than one person!
But yeah, that is the same thing I would suggest. You will just have to track it down.
