Do you mean the time of year where a battery cell goes bad, ruining both the battery and the alternator while you have an Uber passenger in the car an hour from home and every system in your car is cartoonishly shutting off one by one?
Because YEP I GUESS IT'S ABOUT THAT TIME. :(
Isn't it great how cars just have like random lights that come on whose design is so ambiguous that there's no possible chance you could work out what they're trying to indicate.
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.
Dont you have the manual? I did buy a used car and it had manual
No you dont get it, its bad design if you have to read. Also why are there 3847436189347 different lamps that indicate something now? Thats bad design. Oh why do i not know what the single error lamp means and what exactly is broken?bad design.....
All because people dont want to rtfm.
With all the infotainment bullshit they've added to cars these days they really could just tell you what the problem is. Still, RTFM.
True, but who is gonna go to their car dealers mechanic if you can just read a errorcode.
35 to 27...buy a small compressor, its handy
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.
Spooky!
Is that the symbol for a cauldron? I don't get it
Witch's cauldron on top of a rack. How appropriate for Spooktober!
I was genuinely wondering, if that's the joke, having never seen this light before...
This is the warning for low tyre pressure. Often shows up after you've had a tyre change, such as when you go to winter tyres around this time of year.
Interesting fact, the tyre pressure warning isn't always measuring your tyre pressure! At least, not directly.
Some cars have actual pressure sensors inside the wheels which do measure it, while others (like mine) use the ABS sensor - which measures wheel rotations - to determine pressure as a byproduct.
The theory goes that an under-inflated tyre will have to make more revolutions than a properly inflated one to cover a given distance, and so by comparing the current status against a programmed normal, assumed low pressure can be detected.
Because what is 'normal' can change after you inflate your tyres or change them, cars with this type of indirect sensor will also have a button somewhere to reset it (mine is inside the glove box) so you can redefine what 'normal' is and cancel any spurious warning.
Colder air also takes up less volume relative to warmer air, therefore exerting less outward pressure. So, if you haven't aired up since July, it's entirely possible that the lower temperatures alone can cause this light to come on.
Yeah, this is the actual joke here haha.
Or in my experience, when one of the 4/5 transmitters fails.
It never really occurred to me that most people don't check their tire pressure once or twice a month and let it get that bad.
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'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 😆
What did you stop for at a service station before? Do you mean filling the car up?
Why do you need to stop so often at a service station with an EV? I thought the second plus was not having to get it serviced as much.
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
Which biweekly are you referring to?
You don't get it. Snow tires.
You buy a second set of wheels, and its more expensive to add TPMS so you don't and you just get the light 4 months of the year.
Have snow tires, don't have this issue. If I didn't have that measurement thing then I could just reset the system to zero.
Mine got down to 18 psi
fall? yeah, the front will fall off soon
Yeah, that’s not very typical. I’d like to make that point.
remember to tow your car outside the environment if it needs work
Is it normal for tire emergency lights to come on in autumn?
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.
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.
Same
Heat up gas => pressure go up
Cool down gas => pressure go down
pV=nRT
♥️
It's only normal if you've been neglecting to check your tire pressure on a regular basis. Unless you live in a place with a massive yearly temperature differential, properly inflated tires won't lose enough pressure to trigger the TPMS light once temps drop in the autumn.
Prevent a blowout: please stay on top of your tire pressure, people. Check it at least once a month.
But tpms means the car tells me when the tyre pressure gets low?
At least one of my sensors is busted. The gauge says it's fine. Looks like I'll be fixing the issue with electrical tape.
When living in Florida I used to air up my tires constantly because of the temperature overnight. Now in Oregon it's been 2 years and it's only been filled once during an oil change.
