Where is raminator when you need him?

Rojhan, what % is your tint?

 

If you take it back to the dealer, you are going to waste time waiting for them to reset it for you while they service other people. Just do it yourself and remind them next time to do it. Although they should have done it, maybe they simply forgot (and since the warning wasn't on the dash when they did the oil change, it's quite possible), and considering it's so simple to do yourself, I wouldn't waste my time.
