About 30 seconds after I start my car up, There is a long 10 second constant beeping noise, then it stops. Then 10 seconds later it does it one more time. I recently had my engine swapped out and it did it before the new engine so I don't think it's the engine. I have no warning lights lit up on my dash and all of my gauges are where they should be. I was thinking it had something to do with the gauge on the center dash. What does the gauge on the left side show? (the one you can change). Thank you in advance guys!

Can you take a vid? I've never heard of this.

I had something similar happen once, I picked up a nail in one of my tires, the pressure fell below 27 and a loud 10 sec or so beep and the guage began flashing PSI.

Yep, most likely your tire pressure is low. go fill the tires up and it shouldn't do it anymore

Stupid question but does the gauge display the tire pressures?

Yes, if you continue to click the top button it will eventually show the pressure for the two front tires, the left tire is over the right tire, if you click the bottom button the rear tire pressures will show.

The low pressure idicator light is yellow and it looks like this (i)

On Nissans the audio indicator fires off just as the OP has described. During the audiable beep, this light will flash, then go solid...

At some point - 2007 possibly - the actual tire pressure is no longer displayed. Nissan took a step backwards with that move... but of course it still has the low pressure warning symbol/noise.

I've seen both the low tire pressure light, like VO mentioned:



But I swear another time I saw a red "flat tire" light that looked like a flat tire that was bulging out on the bottom. I can't seem to find anything online about this though. It was when my tire pressure was really low and I had the spare on. I don't know if I'm going crazy, but I still haven't found anything after a good amount of searching online.

Ok turns out it's the run flat tire warning light. It does say it makes a noise for 10 seconds though.

This will begin happening more frequently as the seasons change. For every ten degree drop, you'll lose a pound of tire pressure. The Z33 TPMS warning system will activate when pressures drop below 30 psi.

I have an 08 and can vouch that there is no sound, just a flashing light. I never cared to swap out my TPMS's when i got my RPF1s, the same should apply for 07, same with lack of tire pressure display.

My understanding is that you can also take it to the dealership if they window of appropriate tire pressure is too small, they can adjust this so that it is not so sensitive. Maybe someone can chime in on this, but i know this has been the case with alot of newer nissans that i have been around.

+1 on the PSI drop with outside temperature. During the winter I always have to readjust the tire pressure.

+1. The TPMS were such a pain, I never had them installed in my HREs. I just check the pressure old school...
