The phrase refers to the process of extinguishing the tire pressure monitoring system (TPMS) warning indicator in a vehicle. This indicator illuminates when the system detects that one or more tires are significantly under-inflated. Performing the reset procedure aims to recalibrate the system after tire pressures have been adjusted to the recommended levels.
Addressing a lit TPMS indicator is important for maintaining vehicle safety and optimal fuel efficiency. Proper tire inflation ensures predictable handling, reduces the risk of tire failure, and minimizes rolling resistance. Historically, TPMS systems have evolved from direct pressure sensors to indirect systems that infer pressure loss based on wheel speed, leading to varying reset procedures across different vehicle makes and models.
