Low Tire Pressure Indicator: Description and Operation
UNDERSTANDING YOUR TIRE PRESSURE MONITORING SYSTEM (TPMS)
The Tire Pressure Monitoring System measures pressure in your four road tires and sends the tire pressure readings to your vehicle every minute while
you are driving and once every 6 hours when your vehicle is parked. The Low Tire Warning Lamp will turn "ON" if the tire pressure is 25% below the
pressure listed on the Safety Compliance Certification Label (approximately 6 to 9 psi below the manufacturers recommend tire pressure). If the tire
pressure increases 2 psi above the "Light ON" threshold, then the TPMS light will turn "OFF". Once the light is illuminated, your tires are under
inflated and need to be inflated to the manufacturers recommended tire pressure. Even if the light turns "ON" and a short time later turns "OFF", your
tire pressure still needs to be checked. In short, once the light has turned "ON", at least one tire may be under inflated.
