Tire Pressure Monitoring System (TPMS)
TPMS uses sensors mounted in the tire valves to check inflation pressure levels. When the vehicle is moving at a speed of approximately 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 (also referred to as a telltale) in the instrument panel and will display one of the following messages: "Tire Pressure Low" or "Tire Needs Air Now" or "Tire Press.Syst Service required".
Erasing Warning Messages:
- Re-inflate the tire(s) to the correct pressure.
- In certain cases, it may be necessary to drive the vehicle for several minutes at a speed of 20 mph (30 km/h) or faster. This will erase the warning text and the telltale will go out.
Recalibrating TPMS (Canadian models only):
In certain cases, it may be necessary to recalibrate TPMS to conform to Volvo's recommended tire inflation pressures, for example, if higher inflation pressure is necessary when transporting heavy loads, etc.
- Switch off the engine.
- Inflate the tires to the desired pressure and put the ignition in mode I or II.
- Press the MY CAR button in the center console control panel and select Settings > Car Settings > Tire Pressure.
- Press OK/MENU, select "Calibrate Tire Pressure" and press OK/MENU again.
- Drive the vehicle at a speed above 20 mph (30 km/h) continuously for at least 10 minutes. Calibration is done automatically once initiated by the driver and the system does not give any confirmation when calibration is finished.
