Tire Pressure Monitor System (TPMS) - CANADA
The Tire Pressure Monitor (TPM) system (Direct System) uses sensors mounted in the tire valves to check inflation pressure levels. When the vehicle is moving at a speed of 20 mph (30 km/h) or faster, these sensors transmit inflation pressure data to a receiver located in the vehicle. When low inflation pressure is detected or if a sensor is not functioning properly, TPMS will light up the tire pressure warning light in the instrument panel and will display one of the following messages: TIRE PRESSURE LOW, TIRE NEEDS AIR NOW or TIRE PRESS. SYST SERVICE REQUIRED. If a malfunction occurs in the system, the tire pressure warning light will flash for approximately 1 minute and then remain illuminated. TIRE PRESS. SYST SERVICE REQUIRED will be displayed.
