No. 2 TPMS Warning Light (Low Pressure Warning) Illuminates After Engine Start And Turns Off After Driving For Period Of Time [Direct Tire Pressure Monitoring System (TPMS)]: Notes

CAUTION:

The tire pressure cannot be measured accurately after driving for a long period due to increased internal temperature and pressure. Stop the vehicle for approx. 1 hour and then perform the tire pressure measurement and adjustment.
Use a high accuracy digital gauge for measurement of the tire pressure.

NOTE:

The tire pressure normally decreases by approx. 7 kPa {0.07 kgf/cm2, 1.02 psi} per month even if the tire is normal.
The snapshot (temperature and pressure) stored when the TPMS warning light is turned on and off can be verified by operating the M-MDS.
