What does it mean when the car beeps 3 times after starting up? on 2008 Nissan Sentra

While driving I think I heard something sound like it popped. The check engine light did not come on. When I turned the car off and then back on that is when I noticed the 3 distinctive beeps that I do not remember hearing when starting my car before.

No the only light on is the tire pressure light. The noise sounds like the noise for the gps locators that dealers but on your car to lock the car if a payment is not made. I do not have this device on my car but that is the sound of the noise. Could it be my alarm system going bad? The beep for my alarm stopped working a while ago but i was able to still use my key ring to lock and unlock. Just with no beep

To make you check to see if anything is wrong, which you did and found the tire pressure caution light on! Have tires properly inflated.

but the tire engine light has been on for a few weeks and I have had them checked. The light just needs to be reset. The tire pressure light I have dealt with before but the beep is new. I have never heard the beep until now.

Check in your owners manual. That info. is in there! Index is in the back of the book, may take a bt of reading but it will be in there. Look for warning lights and alarms or instrument panel definitions!
