exists. When the malfunction indicator is illu- minated, the system may not be able todetect or signal low tire pressure as intended. System malfunctions may occur for a variety of reasons, including the installation ofreplacement or alternate tires or wheels onthe vehicle that prevent the tire pressuremonitoring system from functioning properly. Always check the system's malfunction tell- tale after replacing one or more tires orwheels on your vehicle to ensure that thereplacement or alternate tires and wheelsallow the system to continue to functionproperly.
NOTE
The system indicates low tire pressure but does not replace normal tire maintenance.For information on correct tire pressure,please refer to the tire inflation pressuretable (see Tire inflation – pressure table(p. 300)), the tire inflation pressure placardlocated on the driver's side B-pillar (thestructural member at the side of the vehi-cle, at the rear of the driver's door open-ing) or consult your Volvo retailer.
WARNING
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control ofthe vehicle.
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

Tire Pressure Monitoring System (TPMS) – changing wheels
Please keep the following in mind when changing or replacing the factory installedTPMS wheels/tires on the vehicle: •Not all aftermarket wheels are equipped with TPMS sensors in the valves.
• If the vehicle is equipped with a tempo-rary spare tire, this tire does not have aTPMS sensor.
• If wheels without TPMS sensors aremounted on the vehicle, a text messagewill displayed in the instrument paneleach time the vehicle is driven above20 mph (30 km/h) for 10 minutes or more.
• 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, including winter tires. Volvo does notrecommend moving sensors back andforth between sets of wheels.
CAUTION
When inflating tires with TPMS sensors, press the pump's mouthpiece straightonto the valve to help avoid bending orotherwise damaging the valve.
CAUTION
• After inflating the tires, always reinstall the valve cap to help avoid damage tothe valve from dirt, gravel, etc.
• Use plastic valve caps only. Metalcaps could corrode and become diffi-cult to remove.
NOTE
•
If you change to tires with a different dimension than the factory-installedones, the TPMS system must bereconfigured for these tires. This mustbe done by a trained and qualifiedVolvo service technician.
• If a tire is changed, or if the TPMS sen-sor is moved to another wheel, thesensor's seal, nut, and valve coreshould be replaced.
• When installing TPMS sensors, thevehicle must be parked for at least15 minutes with the ignition off. If thevehicle is driven within 15 minutes, aTPMS error message will be displayed.

Tire Pressure Monitoring System (TPMS) – messages
Erasing warning messagesWhen a low tire pressure warning message has been displayed and the tire pressure warning light in the instrument panell (
)
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 located on the driver's side B-pillar (thestructural member at the side of the vehi-cle, at the rear of the driver's door open-ing) or the inflation pressure table, seeTire inflation – pressure table (p. 300).
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 telltalewill go out.
NOTE
•Tire monitoring systems use a tem- perature compensated pressure value.This pressure value is dependent ontire temperature and ambient tempera-ture, which can differ from the recom-mended cold tire pressure in the tireinflation table and on the tire pressureplacard located on the driver's side B-pillar (the structural member at theside of the vehicle, at the rear of thedriver's door opening). This meansthat it may sometimes be necessary toinflate them slightly above the recom-mended cold pressure value(approx. 3-4 psi or 0.2-0.3 bar) in orderto reset a low tire pressure warning.
• To help avoid incorrect tire inflationpressure, if possible only inflate thetires when they are cold. The tires areconsidered to be cold when they havethe same temperature as the sur-rounding (ambient) air. This tempera-ture is normally reached after the vehi-cle has been parked for at least3 hours. After driving a distance ofapproximately 1 mile (1.6 km), the tiresare considered to be hot.
CAUTION
•
After inflating the tires, always reinstall the valve cap to help avoid damage tothe valve from dirt, gravel, etc.
• Use plastic valve caps only. Metalcaps could corrode and become diffi-cult to remove.
WARNING
•Incorrect inflation pressure could lead to tire failure, resulting in a loss of con-trol of the vehicle.
• Tire monitoring systems cannot indi-cate sudden tire damage caused byexternal factors (e.g., a blowout) inadvance.

Tire Monitor - introduction
Tire Monitor uses the rotational speed of the tires in combination with signal analysis of theABS sensor signals to determine if they areproperly inflated. When a tire is under-inflated, its diameter (and consequently also its rotational speed)changes. By comparing the individual tireswith each other it is possible to determine ifone or more tires are under inflated. When low inflation pressure is detected or if the system is not functioning properly, TireMonitor 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, for example:
Tire pressure low Check rear
right tire5 or Tire press. syst Service
required.
If two or more tires have low pressure or if the system cannot determine which tire has low pressure, a general text (
Tire pressure low
Check tires) will be displayed.
NOTE
If a malfunction occurs in the system, the tire pressure warning light will flash forapproximately 1 minute and then remain illuminated.
Tire press. syst Service
required will be displayed.
NOTE
The system indicates low tire pressure but does not replace normal tire maintenance.For information on correct tire pressure,please refer to the tire inflation pressuretable (see Tire inflation – pressure table(p. 300)), the tire inflation pressure placardlocated on the driver's side B-pillar (thestructural member at the side of the vehi-cle, at the rear of the driver's door open-ing) or consult your Volvo retailer.

Calibrating Tire Monitor
In order for Tire Monitor to work correctly, tire pressure reference values must be set. Thismust be done each time wheels or tire pres-sures are changed.
Calibration1. Switch off the engine.
2. Inflate the tires to the desired pressure
(consult tire pressure placard located on the driver's side B-pillar (the structuralmember at the side of the vehicle) andput the ignition in mode II, see Ignition
modes (p. 79).
3. Press the MY CAR button on the center
console control panel and select
Settings

Self-supporting run flat tires (SST)
Self-supporting run flat tires are available as optional equipment on certain models. The vehicle must be equipped with one of the tire pressure monitoring systems if tires ofthis type are installed. Tires of this type have specially reinforced sidewalls that make it possible to continuedriving to a limited extent even though the tirehas lost some or all of its inflation pressure.These tires are mounted on special rims (nor-mal tires can also be mounted on these rims). If an SST tire loses inflation pressure, the yel- low TPMS symbol illuminates in the instru-ment panel and a text message is also dis-played. If this happens, reduce speed to notmore than 50 mph (80 km/h). The tire shouldbe replaced as soon as possible.WARNING
• SST tires should only be mounted by service technicians who are familiarwith tires of this type.
• SST tires may only be mounted onvehicles equipped with a tire pressuremonitoring system.
• Do not drive faster than 50 mph(80 km/h) if the monitoring system indi-cates that a tire has lost inflation pres-sure.
• Do not drive farther than 50 miles(80 km) before replacing a damagedSST tire.
• Drive carefully and avoid e.g., hardbraking or fast turns.
• SST tires must be replaced if they aredamaged. A tire of this type cannot berepaired.

Tire sealing system* – general information
Certain models are equipped with a tire sealing system
* that enables you to tempo-
rarily seal a hole in the tread surface and re-inflate a flat tire, or to adjust a tire’s inflationpressure.
IntroductionThe tire sealing system consists of an air compressor, a container for the sealing com-pound, wiring to connect the system to thevehicle’s electrical system via one of the 12-volt sockets, and a hose used to connect thesystem to the tire’s inflation valve.
NOTE
The tire sealing system's compressor has been tested and approved by Volvo.

314* Option/accessory, for more information, see Introduction.
The 12-volt sockets are located in the front tunnel console, on the rear side of the centerconsole in the rear seat and in the cargoarea*.
Accessing the tire sealing systemThe tire sealing system is stowed under thefloor of the cargo area. To access it:
1. Lift the floor hatch in the cargo area.
2. Lift out the tire sealing system.
NOTE
• The tire sealing system is only intended to seal holes on the tire’stread area, not the sidewall.
• Tires with large holes or tears cannotbe repaired with the tire sealing sys-tem.
• After use, stow the tire sealing systemproperly to help prevent rattling.
WARNING
•After using the tire sealing system, the vehicle should not be driven fartherthan approximately 120 miles (200km).
• Have the tire inspected by a trainedand qualified Volvo service technicianas soon as possible to determine if itcan be permanently repaired or mustbe replaced.
• The vehicle should not be driven fasterthan 50 mph (80 km/h) while using atire that has been temporarily repairedwith the tire sealing system.
• After using the tire sealing system,drive carefully and avoid abrupt steer-ing maneuvers and sudden stops.
Tire sealing system–temporarily repairing a flat tire
Temporarily repairing a flat tire is done in two stages:
• Stage 1:
The hole is sealed by pumping
sealing compound into the tire. The car is then driven a short distance to distributethe sealing compound in the tire.

* Option/accessory, for more information, see Introduction.315
NOTE
Do not remove any foreign objects (nails, etc.) from the tire before using the sealingsystem.
• Stage 2:
The tire’s inflation pressure is
checked and adjusted if necessary.
WARNING
• Never leave the tire sealing system unattended when it is operating.
• Keep the tire sealing system awayfrom children.
• Be sure the vehicle is parked safely offthe road and away from moving traffic.
• Apply the parking brake.
