mercedes49 Posted November 12, 2014 Report Share Posted November 12, 2014 The tire low pressure warning light just came on in my 2013 Ford C-max. Should I fill the tire myself or go to the dealership? Thanks. Mercedes Quote Link to comment Share on other sites More sharing options...

Thanks. MercedesPut air in the tire yourself. If the light comes on again, take it to a tire repair shop. You don't need the dealer for this; they are expensive, and a tire is a tire.

lowbar Posted November 12, 2014 Report Share Posted November 12, 2014 The light indicates one of your tires is under inflated. Inflate the tires to the recommended pressure (see drivers door pillar for correct PSI). Closely monitor the tire that was low for awhile to see if it loses air pressure. If it does you most likely have a nail or something similar in the tire. Do NOT take it out yourself. Take the car (or wheel) to your dealer or tire repair shop for repair. Good luck, Quote Link to comment Share on other sites More sharing options...
fotomoto Posted November 12, 2014 Report Share Posted November 12, 2014 My guess: Your tire was borderline low and the overnight cold front here in Texas lowered the air pressure in your tire enough to trigger the warning light this morning. Check and adjust your tire pressures regularly. Quote Link to comment Share on other sites More sharing options...
ScubaDadMiami Posted November 13, 2014 Report Share Posted November 13, 2014 It takes a few minutes for the light to turn off after you fill, so give it a while before you start worrying that it is more than just a top off that you need.

Marc Smith Posted November 13, 2014 Report Share Posted November 13, 2014 same thing happend to me this week. car is garaged over night and its been chilly in the Am so as soon as I leave the garage and start driving in the cold, one of them went low and then once warmed up the light went off. not a bad idea to check the pressures with the change in seasons.....

wab Posted November 13, 2014 Report Share Posted November 13, 2014 Stop at a Discount Tire store.They have a lane (doesn't cost anything) just to check/fill tires, might take a few minutes if they're busy. Quote Link to comment Share on other sites More sharing options...
Tree63 Posted November 19, 2014 Report Share Posted November 19, 2014 My Ford dealer has a service bay for free Nitrogen top ups, since that's what came with the tires. I follow all the other helps mentioned - monitor for leaks, check regularly, watch start of colder weather etc - and also do a visual before any long drives, and at all stops on those drives. Spotted a bulging tire on one drive and that could have been serious safety issue. Quote Link to comment Share on other sites More sharing options...
Kelleytoons Posted November 19, 2014 Report Share Posted November 19, 2014 The only thing I'll note is that my tire pressure was *very* low and the light never did come on -- finally checked to find out it was under 30psi and might have been that way since I picked it up (silly me, I assumed the dealership would have inflated them correctly). I inflated to 40psi and immediately got a 5+ mpg boost. And haven't had to add air more than once a month or so. Bottom line: if you wait until the light comes on you're probably waiting too long. wab 1 Quote Link to comment Share on other sites More sharing options...

With the winter weather, and infrequent fuel fill up, I've taken to checking my tires each time I put in gas. They had lost a couple of lbs last fill up. I keep mine at 44. BTW, my dealer set mine to 34 at delivery. I didn't realize it until my first fill up a month later. One of the tires was actually at 32.

RobMax Posted December 16, 2014 Report Share Posted December 16, 2014 I set mine at 20psi cuz gas is so cheap lately, I don't want to get more than the EPA thinks it gets, or the guys at Consumer Reports got. I'm jes keeding! :thumbsup: Quote Link to comment Share on other sites More sharing options...

drdiesel1 Posted December 17, 2014 Report Share Posted December 17, 2014 Find the tire that's low and check it for nails/screws that could cause a slow leak.These are the most common cause of LTPMS activation. Quote Link to comment Share on other sites More sharing options...
