Tire Pressure Monitoring System (TPMS) TPMS provides a warning if inflation pressure in one or more tires is too low. It also uses a sym-bol (called a telltale) that will flash for60 seconds and then glow steadily if there is asystem malfunction.
TPMS uses sensors mounted in the tire valves to check inflation pressure levels. When the vehicleis moving at a speed of approximately 20 mph(30 km/h) or faster, these sensors transmit infla-tion pressure data to a receiver located in thevehicle. If inflation pressure is too low, an indica-tor symbol will illuminate in the instrument paneland a text message will be displayed.
SymbolExplanation
The symbol illuminates to indicate low tire inflation pressure. If a malfunction occurs in the sys- tem, the tire pressure warning sym-bol will flash for approximately1 minute and then remain illumi-nated.
Each 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 (TPMS) that illuminates a low tire pres-sure telltale when one or more of your tires issignificantly under-inflated. Accordingly, when thelow tire pressure telltale illuminates, you shouldstop and check your tires as soon as possible,and inflate 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 thatthe TPMS is not a substitute for proper tire main-tenance, and it is the driver's responsibility tomaintain correct tire pressure, even if under-infla-tion has not reached the level to trigger illumina-tion of the TPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when thesystem is not operating properly. The TPMS mal-function indicator is combined with the low tirepressure 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. TPMS malfunctions may occur for a variety of reasons, including the installation of replacementor alternate tires or wheels on the vehicle thatprevent the TPMS from functioning properly.Always check the TPMS malfunction telltale afterreplacing one or more tires or wheels on yourvehicle to ensure that the replacement or alter-nate tires and wheels allow the TPMS to con-tinue to function properly.
Messages in the instrument panel
When the TPMS symbol illuminates, the following text messages may also be displayed:
•
Tire pressure low: the tire(s) affected will
also be specified.
•
Tire needs air now: the tire(s) affected will
also be specified.
•
Tire pressure system Service required.
If TPMS cannot determine which tire(s) have low inflation pressure, general messages may be dis-played, such as:
•
Tire pressure low Check tires
•Tire needs air now Check tires
TPMS sensors can be installed on the valve hole area, on the factory-installed wheels as well as onoptional ones.

458If a spare wheel or other wheel without a TPMS sensor is used, a fault message will appear in theinstrument panel after driving for a few minutes. After changing wheels, always check that the new wheels have TPMS sensors to avoid a sys-tem malfunction warning. TPMS does not replace the need for regular tire inspection and maintenance.
RecommendationsTPMS sensors should be mounted on all wheelsused with the vehicle, including winter wheels.
NOTE
•
If you change to tires with a different dimension than the factory-installed ones,the TPMS system must be reconfiguredfor these tires. This must be done by atrained and qualified Volvo service techni-cian.
• If a tire is changed, or if the TPMS sensoris moved to another wheel, the rubbervalve and valve core should be replaced.
• When installing TPMS sensors, the vehi-cle must be parked for at least15 minutes with the ignition off. If thevehicle is driven within 15 minutes, aTPMS error message will be displayed.
WARNING
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control of thevehicle.

Color indications:
• No color indicator
: tire pressure is above
the threshold for a low inflation pressure warning.
• Yellow
: low tire pressure. Stop and check/
reinflate the tire(s) as soon as possible.
• Red
: inflation pressure is very low. Stop
immediately and check/reinflate the tire(s).
• When no tire pressure values or updated tirepressure values are shown then system hasnot learned the tire pressure values. It mightbe necessary to drive at a speed of at least20 mph (30 km/h) for several minutes.
• If the TPMS symbol (telltale) flashes forapprox. 1 minute then glows steadily, and the message

Reinflating tires equipped with the Tire Pressure Monitoring System(TPMS) When low tire pressure has been detected, a message will be displayed in the instrumentpanel and the Tire Pressure Monitoring Systemsymbol will illuminate.
SymbolExplanation
Check and reinflate the tire(s) when the TPMS symbol illuminatesand a message is displayed.
1. Use a tire pressure gauge to check the infla-
tion pressure of the under-inflated tire(s).
2. Re-inflate the tire(s) to the correct pressure (consult the tire pressure placard located on the driver's side B-pillar (the structural mem-ber at the side of the vehicle, at the rear ofthe driver's door opening).
3. In some cases, it may be necessary to drive the vehicle for several minutes at a speed ofat least 20 mph (30 km/h) to erase theTPMS telltale warning and the text message.Please be aware that the TPMS telltalewarning will not go out until the low tire pres-sure has been corrected.

NOTE
To help avoid incorrect tire inflation pressure, if possible only inflate the tires when they arecold. The tires are considered to be coldwhen they have the same temperature as thesurrounding (ambient) air. This temperature isnormally reached after the vehicle has beenparked for at least 3 hours. After driving a dis-tance of approximately 1 mile (1.6 km), thetires are considered to be warm.
CAUTION
When inflating tires with TPMS sensors, press the pump's mouthpiece straight onto thevalve to help avoid bending or otherwise dam-aging the valve.
CAUTION
•After inflating the tires, always reinstall the valve cap to help avoid damage to thevalve from dirt, gravel, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
WARNING
• Incorrect inflation pressure could lead to tire failure, resulting in a loss of control ofthe vehicle.
• Tire monitoring systems cannot indicatesudden tire damage caused by externalfactors (e.g., a blowout) in advance.

WARNING
If heavy vibrations, unsteady steering behavior, or noises should occur while driving, reducespeed and park the vehicle in a safe place.Recheck the tire for bumps, cracks, or othervisible damage, and recheck its inflation pres-sure. If the pressure is below 19 psi (1.3 bar),do not continue driving. Have the vehicletowed to a trained and qualified Volvo servicetechnician.
15. Rechecking the pressure Reconnect the tire sealing system's hose to the tire's inflation valve. 16. Without starting the compressor, check the
inflation pressure on the air pressure gauge. •If the pressure is under 19 psi (1.3 bar), the puncture has not been sealed suffi-ciently and the vehicle should not bedriven. Have the vehicle towed to a trainedand qualified Volvo service technician.
• If the pressure is more than 19 psi(1.3 bar), connect the electrical wire to a12-volt socket, start the compressor andinflate the tire to the correct pressure(see the tire pressure decal on the on thedriver's side B-pillar (the structural mem-ber at the side of the vehicle, at the rearof the driver's door opening). Use the airrelease valve to release some air from thetire if necessary.
17. Switch off the compressor and disconnect the electrical wire from the 12-volt socket. Unscrew the hose from the tire
