Trouble Understanding Tire Preasure Alert

[thundercloud08]

Hello, first time poster here! I just purchase a 2005 RX330 and the tire preasure warning light in the dash keeps coming on. I have checked the tire preasure and adjusted to the recommended preasure. Does the navigation computer tell you what tire needs fixing, or is it just a general warning and it is up to the driver to figure out what tire is low? Any info would be helpful..Thanks.

Did you also check the air in the spare tire?

Thanks for the response. Im not trying to be a wise guy here, but is that possible? Is the spare tire actually monitored by the system?

Are all the tires the same make, tread wear, size etc, and did you reset the tire pressure indicator under the dash?

The car senses circumference not pressure.

I have a 2008 and yes it monitors the air pressure of all 5 tires. I'm not sure about your 05.

Thanks for the help. All the tires are the original tires that came with the car. They have been rotated, can you tell me where the reset button is under the dash?

Thanks!

Mine is right of steering wheel, bottom of dash. Adjust pressure, turn on ign, push button and hold until indicator light blinks 3 times.
