Introduction
NOTE
USA – FCC ID: KR5S122780002 This device complies with part 15 of the FCC rules. Operation is subject to the fol-lowing conditions: (1) This device may notcause harmful interference, and (2) thisdevice must accept any interferencereceived, including interference that maycause undesired operation.
The tire pressure monitoring system1
uses
sensors mounted in the tire valves to check inflation pressure levels. When the vehicle ismoving at a speed of approximately 20 mph(30 km/h) or faster, these sensors transmitinflation pressure data to a receiver located inthe 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 in the text window:
Tire pressure
low or
Tire needs air now.
NOTE
If a fault occurs in TPMS, the tire pressure warning light will flash for approximately 1 minute and
Tire press. syst Service
required will be displayed.
Each tire, including the spare (if provided), should be checked monthly when cold andinflated to the inflation pressure recom-mended by the vehicle manufacturer on thevehicle placard or tire inflation pressure label.(If your vehicle has tires of a different sizethan the size indicated on the vehicle placardor tire inflation pressure label, you shoulddetermine the proper tire inflation pressure forthose tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitor-ing system (TPMS) that illuminates a low tirepressure telltale when one or more of yourtires is significantly under-inflated. Accord-ingly, when the low tire pressure telltale illu-minates, you should stop and check yourtires as soon as possible, and inflate them tothe proper pressure. Driving on a significantlyunder-inflated tire causes the tire to overheatand can lead to tire failure. Under-inflationalso reduces fuel efficiency and tire tread life, and may affect the vehicle's handling andstopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driv-er's responsibility to maintain correct tirepressure, even if under-inflation has notreached the level to trigger illumination of theTPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate whenthe system is not operating properly. TheTPMS malfunction indicator is combined withthe low tire pressure telltale. When the sys-tem detects a malfunction, the telltale willflash for approximately one minute and thenremain continuously illuminated. Thissequence will continue upon subsequentvehicle start-ups as long as the malfunctionexists. When the malfunction indicator is illu-minated, the system may not be able todetect or signal low tire pressure as intended.TPMS malfunctions may occur for a variety ofreasons, including the installation of replace-ment or alternate tires or wheels on the vehi-cle that prevent the TPMS from functioningproperly. Always check the TPMS malfunc-tion telltale after replacing one or more tiresor wheels on your vehicle to ensure that thereplacement or alternate tires and wheels

allow the TPMS to continue to function prop- erly.
NOTE
TPMS indicates low tire pressure but does not replace normal tire maintenance. Forinformation on correct tire pressure, pleaserefer to the tire inflation pressure table inthis chapter or consult your Volvo retailer.
Erasing warning messagesWhen a low tire pressure warning message has been displayed, and the tire pressurewarning light has come on:
1. Use a tire pressure gauge to check the
inflation pressure of all four tires.
2. Re-inflate the tire(s) to the correct pres- sure (consult the tire pressure placard or the inflation pressure table on page 316.
3. In certain cases, it may be necessary to drive the vehicle for several minutes at aspeed of 20 mph (30 km/h) or faster. Thiswill erase the warning text and the warn-ing light will go out.
WARNING
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control ofthe vehicle.
Changing wheels with TPMSPlease note the following when changing or replacing the factory installed TPMS wheels/tires on the vehicle:
• Only the factory-mounted wheels are equipped with TPMS sensors in thevalves.
• If the vehicle is equipped with a tempo-rary spare tire, this tire does not have aTPMS sensor.
• If wheels without TPMS sensors are mounted on the vehicle,
TIRE PRESS
SYST SERVICE REQUIRED will be dis-
played each time the vehicle is driven above 25 mph (40 km/h) for 10 minutes ormore.
• Once TPMS sensors are properly instal-led, the warning message should notreappear. If the message is still displayed,drive the vehicle for several minutes at aspeed of 20 mph (30 km/h) or faster toerase the message.
• Volvo recommends that TPMS sensorsbe fitted on all wheels used on the vehi-cle. Volvo does not recommend movingsensors back and forth between sets ofwheels.
CAUTION
When inflating tires with TPMS valves, press the pump's mouthpiece straightonto the valve to help avoid bending orotherwise damaging the valve.
CAUTION
• After pumping the tires, always rein- stall the valve cap to help avoid dam-age to the valve from dirt, gravel, etc.
• Use plastic valve caps only. Metalcaps could corrode and become diffi-cult to remove.
