Change tire pressure to display in psi?

mealto · 01-03-2013, 12:57 AM

I have heard a few members report their tire pressure in psi? Is there a way to show psi tire pressure in the MDX dash?

It is in the MDX's MID under tire pressure.

mealto,

If you are referring to switching from metric, I don't know of any user available settings for that. That doesn't mean it's impossible, just that I haven't found it. You may want to contact your dealer.

If you are just having trouble finding the tire pressure display, press the info button until "tire pressure" is displayed. then, press the sel/reset button. That should display the tire pressure for the 4 tires.

This is based on my '11.

@symmetrical, I went through the entire MID and could not locate that setting. Let me try again. Grrrr!

@Bill_de, I have not found it either. Yes, I mean switching from kilo pascals to psi. Wow, that Physics class did come in handy! lol

Think of it as figuring out tips in a restaurant. Roughly 15%

Yes true. But 15% of 228 versus 240 vs 218 is not as accurate as I would like. Will have to go through MID to dig up that setting. Let's hope it's there.

How does your mid display mileage ... mpg or kpl?

If it is metric, maybe changing that would change the tire pressure. Just guessing out loud.

mealto · 01-03-2013, 06:35 PM

It displays liters / 100 kilometres. Is the metric option in the MID or Nav unit adjustments. Went in both and could not find anything. Is it me or the crappy interface? Lol

Bill_de · 01-03-2013, 07:16 PM

Was this vehicle originally sold in Canada? Everything you are saying indicates it was, in which case it looks like you may not be able to change it. Have you asked a dealer yet?

The only other thing you might try, the owner's manual show a 'reset all defaults" in the mid setup. If that still keeps everything metric, you probably have a Canadian car.

One more question. Is it the same for driver 1 and driver 2?

Not to mention the outside temp., inside temps and the odometer and trip odos would be metric as well... Curious if only the tire pressure was in kPa...

I don't know of any user available settings for that.

Yes this is a Canadian MDX. Pressure is displayed as kpa. So I guess that is metric? I cannot find anything in the settings to change kpa to psi.

Don't think there is a option in any of the menus to change the system. Might only be done at a dealer.

All you really need to know is one number - how many kpa (kilopascals) you want to keep your tires inflated to. The recommended 32 psi is equal to 221 kpa.

As always, you can expect the pressure to be lower on cool days, to be higher on warm days or when the tires have been in the sun or in a heated garage, and to rise as you're driving and the tires warm up.

If you use a conversion factor of 1 psi = 6.9 kpa (or 1 kpa = 0.145 psi), that's all the accuracy you'll need for setting your tire pressures. More precise factors are 1 psi = 6.89475729316836 kpa and 1 kpa = 0.145037737730209 psi. (And no, I'm not making those numbers up.)

kpa = KILOpascals = metric
psi = POUNDS per square INCH = imperial
