Re: new owner 2 questions
The yellow exclamation mark is the tire pressure monitor indicator; when it is lit, one or more of your tires are low and need to be filled (I think it is 32 psi for the XF). One wrench symbol means Service A; two wrenches means Service B. The service periods are calculated by days as well as by miles, so if your car sat on the dealer's lot for a while, you might want to change the oil, and it is also possible that the tires are low from sitting in one place for a long time.
