TURNS OFF AFTER DRIVING FOR PERIOD OF TIME
id020300800600
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/cm
2
, 1.02 psi} per month even if the
tire is normal.
• The FFD (temperature and pressure) stored when the TPMS warning light is turned on or off can be
verified by operating the M-MDS.
