Aren't Canadian Acuras supposed to have TPMS in KPa??
Just bought a new 2018 TLX Tech A-Spec. CANADIAN MODEL.
Was very surprised to see my dashboard info re: tire pressure was showing in PSI, not KPa. This is my 3rd Acura (2 RDX's before this) and always showed correct units. I cannot find any reference to this being user changeable, as in going from one to the other. According to the Owner's Manual Canadian cars will always show KPa (just like they show speed in KPH, not MPH) and US models will show PSI.
Yet I have a Canadian model showing only PSI.
Is this in fact user reconfigurable? It's not a big deal but takes getting used to.

I get the feeling that Acura switched to Psi because it is the much more commonly used measure, even if KPa is actually the correct measure to be used in Canada. I must admit, you're the first person I've ever come across that prefers kpa to psi. I'm born and raised here and an engineer to boot, and kpa has no relevance to me... I was confused the first time I saw it in my Acura

It might be worth taking it into the dealership and asking if they can switch it. Sometimes it's matter of pushing and holding certain buttons and it's not written down in the owners manual. I had that issue when I had a Hyundai Sonata. The car would default to American units after a battery reset and the manual didn't say how to switch it.

I had a 15 that was KPA, I now I have an 18 that is PSI. I dont recall seeing anything in the menus about changing it. But I never looked that hard since I prefer PSI anyway lol.

When I first accessed the TPMS screen in the showroom when picking up the new car, I was convinced that all the tires were FLAT since the measurements were in the mid-30's when I was expecting 230's!!! Once I realized it was OK, and that it was back to old-fashioned PSI it just made me wonder why

I wonder if this was a complaint from people. Your dash reads kpa... but your air pressure gauge reads psi. I think fuel economy, speed and distance are likely somehow mandated by the government to be in our respective metric system, but maybe for something like tire pressure display it doesn't matter?

2018 TLX Aspec
i've got PSI's on our 18's Aspec I always went with PSI never knew KPA was considered a Canadian unit.
Speaking of PSI, it was delivered with 36PSI which is 4 PSI higher than the sticker. Was there a benefit for them to fill it with extra PSI? Is it less likely to blow since they are low profile tires?

There are four lights!
LOL, I'm a chemist that literally works with metric every single day, but I prefer my height in feet/inches, pressure in PSI and weight in pounds. I'm 5' 10" damnit, not 178 cm! Born and raised Canadian and was also taught metric from day one in school.

My Canadian 2010 TSX was in kPa and it annoyed me like crazy. I work and think in psi... My 2018's psi display is great. Now if only I could change the HVAC temp to F.... This would provide us with more granular control on the temp than in full degC increments!

That was one of my pet peeves with my 2006 and 2010 TLs. I could never get the pressures to be exact in KPa. A change between metric and English would have been welcome as would C vs F and mi.vs km.
