The dashboard low tire pressure light that illuminates when the air pressure in one or more of the vehicle’s tires drop 25% or more below the placard pressure. This is a solid light, which remains lit until the tires are inflated to placard pressure. Some vehicles also require all tire pressures (up to 5, if the spare is equipped with a sensor) to be fully at placard and/or a vehicle reset to clear the light.
