With and without "Mesage Center" respectively (pretty sure)

With the engine on...

Push "Setup" button, until your driver display says something like "Press Reset for system check".

Then push Reset. The system check will start, rotating through a series of checks.

About the fifth or sixth check will be the tire pressure. The system will sound the tone (same one that starts w/the light) and It'll say something like "Check Tires Pressure" on that moment press and hold for 3 or 4 seconds Reset. When you release the Reset button It'll show "Hold Reset if tires are OK". While that's up, hold the Reset button. After 3 or 4 seconds, the tire warning light will blink 2 or 3 times and then will stop .You need to be ready for it, because you don't get very long to release.

Most will reset when the air pressure in all the tires is close to the same pressure.

I believe that one of your tires is low on air causing the pressure monitor to kick in. Check all your tires to make sure the inflated to the proper PSI which will be located on one of the door jambs

Must have codes for check engine light cleared with scan tool. Check all tire pressures and road test up to 35 mph. Tire message should clear if low tire was problem. If light for tires remains then possible radio frequency sensor problem. Sensor replacement may be necessary. Sensors have alkaline non-serviceable batteries. If battery is dead sensor will have to be replaced.

Continue to press the button for 3 seconds, then release. After 3 seconds, the low tire pressure warning lamp will flash 3 times, indicating that the low tire warning system reset procedure is complete.
