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. 285)), 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.

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 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. 285)), 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. 73).
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.

The 12-volt sockets are located in the front tunnel console and on the rear side of thecenter console in the rear seat.
Accessing the tire sealing systemThe tire sealing system is stowed under thefloor of the trunk. 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.

WARNING
The bottle is equipped with a catch to keep it securely in place and help preventsealing compound leakage. Once in place,the bottle cannot be unscrewed. This mustbe done by a trained and qualified Volvoservice technician.
5. Remove the valve cap from the tire’sinflation valve and screw the tire sealing system’s hose connector onto the valveas tightly as possible by hand.
6. Connect the electrical wire to the nearest 12-volt socket in the vehicle.
NOTE
Be sure that none of the other 12-volt sockets is being used while the compres-sor is in operation.
7. Start the vehicle’s engine.
WARNING
The vehicle´s engine should be running when the tire sealing system is used toavoid battery drain. Therefore, be sure thevehicle is parked in a well ventilated place,or outdoors, before using the system.
8. Start the tire sealing system’s compres-sor by pressing the on/off switch to posi- tion I.
WARNING
• Never stand next to the tire being infla- ted when the compressor is in opera-tion.
• If cracks, bubbles, etc. form on the tire,switch off the compressor immediately.
• If there is visible damage to the sidewallor the rim, the tire cannot be repaired.The vehicle should not be driven if thisoccurs. Contact a towing service orVolvo On Call Roadside Assistance ifapplicable.
NOTE
The air pressure gauge will temporarily show an increase in pressure to approxi-mately 88 psi (6 bar) while the sealingcompound is being pumped into the tire.The pressure should return to a normallevel after approximately 30 seconds.
9. Within seven minutes, inflate the tire to
between 22—44 psi (1.8—3.0 bar). Switch off the compressor briefly to get aclear reading from the pressure gauge.

09 Wheels and tires

* Option/accessory, for more information, see Introduction.303
CAUTION
The compressor should not be used for more than 10 minutes at a time to avoidoverheating.
WARNING
If the pressure remains below 22 psi (1.8 bar) after approximately sevenminutes, turn off the compressor. In thiscase, the hole is too large to be sealed andthe vehicle should not be driven.
10. Switch off the compressor and discon-
nect the electrical wire from the 12-volt socket.
11. Unscrew the hose from the tire’s inflation valve and reinstall the valve cap.
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. Metal capscould corrode and become difficult toremove.
12. Immediately drive the vehicle for approxi-
mately 2 miles (3 km) at a maximum speed of 50 mph (80 km/h) to distributethe sealing compound in the tire.
CAUTION
If your vehicle is equipped with the Tire Pressure Monitoring System (TPMS), theuse of the sealing compound may lead toincorrect tire pressure readings or in rarecases, damage to the tire pressure sensor.Use the tire sealing system to check andadjust the damaged tire's inflation pres-sure.
NOTE
•Safely stow the tire sealing system in a convenient place as it will soon beused again to check the tire’s inflationpressure.
• The empty bottle of sealing compoundcannot be removed from the bottleholder. Consult a trained and qualifiedVolvo service technician to have thebottle removed and properly disposedof.
WARNING
If heavy vibrations, unsteady steering behavior, or noises should occur whiledriving, reduce speed and park the vehiclein a safe place. Recheck the tire forbumps, cracks, or other visible damage,and recheck its inflation pressure. If thepressure is below 19 psi (1.3 bar), do notcontinue driving. Have the vehicle towedto a trained and qualified Volvo servicetechnician.
Tire sealing system – checking inflation pressure
The tire sealing system can also be used to check the tires' inflation pressure.
Stage 2: Checking inflation pressure1. Connect the tire sealing system as
described in stage 1, see Tire sealing
system* – sealing hole (p. 301).
2. Refer to the inflation pressure table in this chapter for the correct inflation pressure.If the tire needs to be inflated, start thetire sealing system’s compressor. If nec-essary, release air from the tire by turningthe air release knob counterclockwise.
CAUTION
The compressor should not be used for more than 10 minutes at a time to avoidoverheating.
WARNING
If you interrupt your trip for more than 1 hour, check the inflation pressure in thedamaged tire again before continuing.
