To recalibrate the tire pressure sensor on a 2008 Lexus IS 250 in the US, first ensure your car is parked safely. Then, check that the tire pressures are correct: 35 psi for the front and 37 psi for the rear tires with sizes F: 225/40R18 88Y and R: 255/40R18 95Y, and 35 psi for the front and 38 psi for the rear for other tire sizes. Next, turn the car to the 'on' position without starting the engine. Use the left or right arrow buttons until the initialization setting appears on the screen. Press the on/off button until the tire pressure warning light flashes three times. Finally, switch the vehicle to the ACC or lock position after a short delay.
To recalibrate the tire pressure monitoring system (TPMS) in a 2008 Lexus IS250, navigate to the "pressure initial" setting on the information display using the left and right arrow buttons. Press and hold the center button for three seconds until you hear a chime and see the light flash three times. Let go of the button, start the car, and either let it idle or drive a short distance to complete the recalibration process.
