Tire pressure light came on after a tire rotation

Many vehicles use an indirect tire pressure monitoring system that compares how fast each wheel spins. After a rotation or pressure adjustment, it needs to be calibrated so it learns the new normal. Until then, the warning can stay on even when pressures are correct.

The calibration is usually started from the vehicle settings menu on the instrument cluster or display, and then the system completes it during normal driving, which can take some time. Your owner's manual shows the exact steps for your vehicle.

Before calibrating, double-check all four tires cold with a reliable gauge, since calibrating with a low tire teaches the system the wrong value. If the light comes back after calibration, have the tires checked for a slow leak, such as a nail.
