| On another board I visit, many members including myself got two messages this past weekend of "low air" in tires. They were down to 27 lbs. I am meticulous about maintaining my vehicles tires pressures etc....could it have been the cold weekend weather? MANY members had the same notification, HOW ABOUT YOU FOKLS???? :confused: |

It has gotten pretty chilly (SoCal) for the past 3 weeks hitting 38-42 at night. Tire pressure seems to stay exactly at 32 on mine as I always check MID every morning drive.

Wow that's odd, you must have a gold garage.
What is the temp of your tires once you have driven around for awhile?
Mine have started out at 29 on cold mornings, but in about 10 minutes they are up to 32-34. |

I had this happen to me a couple of weeks back after a particularly cold night in the country. I'm assuming that the tires were hovering around 32psi prior to the incident, but when I started her up for my Sunday morning trip to Starbuck's with the baby in tow (mommy gets to sleep in), they were at 26/27psi. They warmed up to about 28/29psi before I stopped at a gas station and pumped them up to 35psi, which is where they are currently.

| They were at 30 when I looked last. Keep in mind I don't drive every day.....by the time I was ready to drive her to a company meeting I had the email warning me about my tire pressure. They were 27 lbs. each! So I got my air pump out (yes LS I have all that snitz too) and pumped them to 32 as cold. Now they indicate 33 lbs when warmed up..... |

Email warning feature? Is that new gadget I don't know about or perhaps might have missed fr the manual?
:hmmm: |

This tire pressure loss is normal during cold weather.
For every 10 degrees Fahrenheit change, the tires’ air pressure will change by about 1 pound per square inch (psi). |

Message center in your Navi! A little white envelope icon will appear in the upper right hand corner of your navi when you have an issue..... |

| Just added air to the RDX tires. They to were slightly low.....took her for a spin. Gosh this sucker is fast! I guess the more she breaks in its all about TURBO POWER esp. with this chilly weather. She is at 19,000 miles now....:eek: |

| So one who doesn't drive much with colder weather can expect to lose tire pressure? I guess I better check the TANK (RL) that's in hybernation now.......:rolleyes: |

| Get a digital meter (or even a non digital :p) and test the tire pressure before you guys pump it up because you may over inflate it. It does show up less due to the cold but that's on the TPMS double check it. I saw mine drop from 32 to 28 within the week ...but with the digital guage it's reading higher ...so be careful ..over inflation is just as bad as under. |

Experienced the same symptom on my MDX.
Since I live in the great white north (Montreal!) I can tell your for a fact that outside temperature variation will play with your tire pressure (I see this situation every Spring and Autumn).
What is done in northern climate is to fill up the tire with Nitrogen instead of air. The nitrogen molecule is not as sensitive as the air in the tires to temperature variation.
Furthermore the Nitrogen humidity level is lower and safeguards your TPMS sensor.
For those who are tempted to reply to me that the Air in the tires already have nitrogen, I know. The entire basis is to try to fill up the tire with more then 95% of Nitrogen. :D |

| I have a digital one, one that came with my compressor and the old fashion one and now the TPMS! I always check for consisitancy before pumping MORE air or nitro! |

Actually, I think the TPMS will trigger at about 27psi. So if your pressure was at 27 when you checked it, that was the reason for the warning.
Many of us who got the messages checked our pressure and all tires were at 30 or above. I wonder if it triggered at some point in the dead of night when the car was just sitting in the garage and the temp (and therefore the tire pressure) bottomed out?
The other theory I have is that the message is triggered by the calendar in the car, since pressure drop in the winter is normal and they're just being pro-active.

I just noticed that I had 2 messages (with the white envelope) but they were informational type messages about TPMS and something related to pressure (can't remember exactly). It's not the "Check Tire Pressure" message on the MID when the tire pressure is truly low. Threshold is 25 psi. Anything below will set off the low pressure indicator in the MID and will go off once the pressure exceeds 29 psi.
When the car is off, the sensors all go into sleep mode until the ignition is turned on. This is a battery conservation effort - would have been a real hassle if those tiny lithium batteries have to be replaced every few years. |

Yeah, I think we all just got the "envelope" message, and not a real TPMS warning.
What you say makes me think this is just a message triggered by the vehicle's calendar.

The calendar theory is an interesting one.
Or the messages might have also been sent from Acura via AcuraLink. Hit a certain date and bam, messages get sent to all Acuras equipped with AcuraLink.
Eitherway, I tend to agree that this is more date driven rather than actual temperature/pressure driven.
By the way, when did you guys get your messages? I got my "Check your tire pressure" message on Dec 3. |

Same issue here in MA... It is due to the cold.

| Just this evening, running an errand, low and behold another white envelope icon is on my navi screen: TPMS greeting AGAIN ! This time all my tires were precisely at 32 each "per the TPMS"! :o |
|
|
| eujinc |
Yep. Got one yesterday too. Low pressure while the TPMS says it's 30.
I haven't put any air in since I bought it back in Aug. Guess this is as good a time as any to put in the 2 additional psi. |

| I got 3 messages yesterday in Houston, TX - it was 80 degrees outside! It's in for service today and I asked the dealer to look into it. |

Due to changes in temperature across the USA, Honda may have thought it advisable to just warn all users via the Acuralink.
It was 75 here too on Dallas the day I got mine!

| Well I think it is totally annoying! It goes to show you how many folks are clueless about maintaining vehicle tire air pressure across the US with their MDX's! |
