My wife and I went to the grandson's basketball the other night in seperate cars. I left about 15 minutes before her. About the time I got home she called and said the tire pressure warning light was on. She was concerned about ruining a tire and of course she doesn't know how to change the screen to show the pressure in each tire. I told her it would probably be OK to drive on home (about 10 miles).

When she got home I checked the screen and there was 28 psi in one tire and 26 psi in the other 3. I aired all the tires to 35 psi in the front and 32 psi in the rear. I think the recommended pressure is 32 front and 30 rear. I was surprised that after airing the tires the screen read exactly what my gauge read.

I guess I ought to check the pressure more often and not let the tires get that low. I hadn't checked the pressure since we bought the RL in February. That's the problem with computers and electronics - you get to relying on them and forget your common sense. Maybe Acura should have a compressor that automatically maintains property tire pressure.

 

IMO a compressor that maintains the tire pressure will eventually be offered as a standard feature on cars - not yet though

 

oooh, that is a great idea. sad they havent implemented it yet.

 

I got a similar message the other day. We hit a cold snap and so the air contracted a bit and the pressure was down to 26/27. The next day our temps were back in the high 70s and my tire pressure was in the 30/31 range. I added a little air to put them at 32/33 so maybe that will counter any colder temps we have...

It did get me to thinking though. This is the first vehicle I have owned with the TPMS. Unfortunately, lower tire pressure due to weather changes is not something I have always been alert about so I'm sure I have driven previous cars with well under-inflated tires and not put much thought into it.

 

I'm sure that is the same thing that happened to mine. The temperature had been in the 60's and 70's, then dropped to the 30's. The pressure monitoring system is a nice feature. My 05 Pilot has a monitoring system, but does display the pressure. It just notifies you if the pressure is too low and will show which tire. Wish it had the display like to RL.

 

Typically, when the temperature dropps 10 degrees, you lose 1 psi in tire pressure.
