Tire pressure monitoring - overview
Volvo provides two different systems to monitor tire pressure: Tire Pressure Monitoring System(TPMS) or Tire Monitor.
Determining which tire monitoring system is in your vehicle
To see which system is installed in your vehicle, press the MY CAR button on the center console.

(p. 305).

pressure, see Tire Pressure Monitoring Sys-
tem (TPMS) – general information (p. 308).
IntroductionEach tire, including the spare (if provided), should be checked monthly when cold and inflated tothe inflation pressure recommended by the vehi-cle manufacturer on the vehicle placard or tireinflation pressure label. (If your vehicle has tiresof a different size than the size indicated on thevehicle placard or tire inflation pressure label, youshould determine the proper tire inflation pres-sure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoringsystem that illuminates a low tire pressure telltale (
) when one or more of your tires is signifi- cantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stopand check your tires as soon as possible, andinflate them to the proper pressure. Driving on a significantly under-inflated tire cau- ses the tire to overheat and can lead to tire fail-ure. Under-inflation also reduces fuel efficiencyand tire tread life, and may affect the vehicle'shandling and stopping ability. Please note that atire pressure monitoring system is not a substi-tute for proper tire maintenance, and it is the driv-er's responsibility to maintain correct tire pres-sure, even if under-inflation has not reached thelevel to trigger illumination of the system's lowtire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when thesystem is not operating properly. The monitoringsystem's malfunction indicator is combined withthe low tire pressure telltale. When the system detects a malfunction, the tell- tale will flash for approximately one minute andthen remain continuously illuminated. Thissequence will continue upon subsequent vehiclestart-ups as long as the malfunction exists. Whenthe malfunction indicator is illuminated, the sys-tem may not be able to detect or signal low tirepressure as intended. System malfunctions may occur for a variety of reasons, including the installation of replacementor alternate tires or wheels on the vehicle that

Tire Pressure Monitoring System (TPMS) – general information TPMS uses sensors mounted in the tire valves to check inflation pressure levels. When thevehicle is moving at a speed of approximately20 mph (30 km/h) or faster, these sensorstransmit inflation pressure data to a receiverlocated in the vehicle.
NOTE
USA – FCC ID: KR5S180052050 This device complies with part 15 of the FCC rules. Operation is subject to the followingconditions: (1) This device may not causeharmful interference, and (2) this device mustaccept any interference received, includinginterference that may cause undesired opera-tion.
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, Tire needs air now or Tire
press. syst Service required.
NOTE
If a malfunction occurs in the system, the tire pressure warning light will flash for approxi-mately 1 minute and then remain illuminated.
Tire press. syst Service required will be
displayed.

Please keep the following in mind when chang- ing or replacing the factory installed TPMSwheels/tires on the vehicle:
• Not all aftermarket wheels are equipped withTPMS sensors in the valves.
• If the vehicle is equipped with a temporaryspare tire, this tire does not have a TPMSsensor.
• If wheels without TPMS sensors are moun-ted on the vehicle, a text message will dis-played in the instrument panel each time thevehicle is driven above 20 mph (30 km/h) for10 minutes or more.
• Once TPMS sensors are properly installed,the warning message should not reappear. Ifthe message is still displayed, drive the vehi-cle for several minutes at a speed of 20 mph(30 km/h) or faster to erase the message.
• Volvo recommends that TPMS sensors befitted on all wheels used on the vehicle,including winter tires. Volvo does not recom-mend moving sensors back and forthbetween sets of wheels.
