Q: The "Check Tire Pressure" Message and light comes on. Tire pressure OK> Serious on 2010 Lincoln MKZ

Comes on and off intermittantly. Our tire pressure is O.K. How do we get this to stop? Is it serious or dangerous to keep on driving while it is on?

Does it come on when first driving , then go off after a few miles on the road? It may just be temp. changes and pressure right at threshold for sensors. Driving warms up tires (10 degrees = 1 PSI). If low pressure limit is 27PSI and tires are set to 30PSI in the afternoon after driving a few miles (like to a station to put air in them) and it's 70 degrees out , and you go home , park it and come out the next morning and overnight temp. dropped enough, pressure at start-up could be just below limit causing the light to come on until warmed up a little. Hope this made sense.
Thanks, I will pay a little more attention to just when it comes on and goes off. And yes, you did make sense. Have a good day!
