No.2 Tpms Warning Light - Mazda CX-7 2007 Workshop Manual

No.2 TPMS WARNING LIGHT (LOW PRESSURE WARNING) ILLUMINATES AFTER ENGINE START AND
TURNS OFF AFTER DRIVING FOR PERIOD OF TIME
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
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.
TPMS warning light (low pressure warning) illuminates after engine start and turns off after driving

for a period of time.
[TROUBLESHOOTING HINTS]
• The tire pressure decreases (approaches value to illuminate TPMS warning light) when the internal temperature of the tire
is low.
STEP
1 INSPECT THE TIRE
• Is there any foreign object adhering to the
tire?
2 MEASURE THE TIRE PRESSURE WHEN THE
ENGINE IS COLD
• Has the tire pressure decreased
(approaches value to illuminate TPMS
warning light)?
3 IS THE MALFUNCTION CORRECTED?
