A tire-pressure warning means the tire pressures or monitoring system need attention. Check pressures with cold tires and use the values on the vehicle's tire-information label, not the maximum pressure molded into the tire sidewall.
Temperature changes can affect pressure, but they are not a reason to ignore the warning. A light that flashes before remaining on may indicate a monitoring-system fault; consult the manual for your model.
Stop safely if a tire is visibly damaged or handling changes. Contact The Car Clinic of Miami in Miami with the measured pressures and warning pattern, rather than assuming a sensor fault without checking the tires.
