I was genuinely wondering, if that's the joke, having never seen this light before...

Yeah, that’s not very typical. I’d like to make that point.

I check mine when my car tells me to

In the last month, the high temps where I live have dropped approximately 40 degrees.

That enough to drop tires pressure to the point of the light coming on if you're not checking it at least biweekly

Or they made their seasonal change from their summers to winters, and if, like me, you have separate rims so you can easily do it at home, you now get to drive around with the car whining about no tpms. Because fucking cars can't have this as built in diagnostic functionality in these giant computers on wheels.

When I have time I'll pop over to a shop that can reprogram them to the second set, but it's not exactly priority numero uno.

I used to be somebody who checked tire pressures much more often. Oil level too.

But even though our current vehicles are 12 and 13 years old, the tire pressure monitoring works right away on a cold day, and its threshold before turning on the light isn't super low. It's high 20s psi I believe.

It's not that I want to ignore the workings of my car. I often enjoy using my phone olconnected to my bluetooth OBDII scanner to provide a bunch of extra gauges. I drive an old Mazda3 and it doesn't even have a temperature gauge, just a light. So it's cool being able to monitor coolant temperature, voltage, actual gallons of fuel in the tank, and various other sensors if I feel like it.

I've just realised I've completely stopped checking mine since switching to an EV. I can go a couple of months without even stopping at a service station, so the old habit is broken.

Edit: For the confused people replying to me, we don't call them gas stations outside of North America. We call them service stations or petrol stations.

I'm sure we do dumb things too, but calling a liquid "gas" is fucking comical btw 😆

Chances are that the alternator was already bad, but symptoms didn’t manifest until the battery started to die. A running car should be able to stay alive purely from the alternator. It’s not a great long term solution, since it causes extra wear on the alternator. But it is possible to just push-start it and then keep it alive with the alternator alone.

Its a low tire pressure light.

In the fall, lower temperatures cause tire pressure to drop.

I don't own any horse shoes.

Just the low tire pressure warning.

Cold temperatures reduce the pressure, and since air leaks out of tires naturally over time, it is quite common for the change in temperature to suddenly put your tires below the threshold for normal tire pressure.

We usually get a big enough quick drop in temperatures that I get this each autumn. Even with new tires

Yes, if the tires were close to the cut off before the temp dropped. The sensor in my vehicle readstire pressure about 10% low in colder weather, which can be enough to trigger the warning on chilly mornings if I haven't topped it off during the summer.

Heat up gas => pressure go up

Cool down gas => pressure go down

pV=nRT

My winter rims don't have sensors because those cost money.

I live somewhere that I can't get away with all season tires from late October until late April.

My car occasionally displays a blue tick, what the hell is that supposed to mean? It only comes up maybe once every 4 or 5 months so it's really hard to work out a pattern.

I got the same issue with my BMW, except it's a green arrow pointing either left or right that flashes and makes a ticking sound. Only lasts for a few seconds though.

Dont you have the manual? I did buy a used car and it had manual

You should read your car's manual.

4-5 month is an awfully long time to be too lazy to rtfm

I mean, I agree it's silly design, but come on

I just got a used Cadillac and it has this little blue icon quite frequently. Had to get out the manual. It means I'm driving over the speed limit. Fuck's sake what a useless light.

I used to drive a Sprinter, and on the dashboard was a light with iconography of waves, wind, and raindrops. I concluded that it was warning me of a storm at sea.

I got a Ryobi battery powered air pump. It's so nice to not have to drag out the whole compressor just to add a couple lbs my tires when the temperature drops.

Don't buy the cheapest tho, look online for one that has metal piston & cogs (are are only slightly more expensive, or perhaps even not more expensive).

The plastic ones break easily when heated (5 ~ 10 minutes).

But yeah, why not just pump the air at gas stations?
They usually have to recertify the gauges once a year.
