To reset the tire pressure monitoring system on the 2014 Lexus GS350 in America, start by confirming that you are parked safely and that the tire pressures are accurate. The recommended tire pressures are 33 psi for both front and rear 225/50R17 tires, 35 psi for front and 36 psi for rear 235/40R19 as well as the F: 235/40R19 R: 265/35R19 tires, and 33 to 35 psi for both front and rear P235/45R18 tires. Once you've verified the pressures, turn the car to the on position without starting the engine. Press and hold the tpms reset button until the tire pressure warning light blinks slowly three times. Wait approximately 5 minutes before turning the car off and then back on.
To recalibrate the tire pressure monitor in your 2014 Lexus GS 350, start by turning the car's key to the "on" position and pressing the designated TPMS button below the dashboard until the TPMS light flashes. After that, start the car and leave it running for a minimum of 20 minutes to complete the reset process for the TPMS system.
