Tire inflation – checking pressure
Inflation pressure should be checked when the tires are cold.
Cold tiresThe tires are considered to be cold when they have the same temperature as thesurrounding (ambient) air. This temperature is normally reached after the vehicle has been parked for at least 3 hours. After driving a distance of approximately 1 mile (1.6 km), the tires are considered to behot. If you have to drive farther than this dis-tance to pump your tire(s), check and recordthe tire pressure first and add the appropriateair pressure when you get to the pump. If checking tire pressure when the tire is hot, never "bleed" or reduce air pressure. Thetires are hot from driving and it is normal forpressures to increase above recommendedcold pressures. A hot tire at or below recom-mended cold inflation pressure could be sig-nificantly under-inflated.
To check inflation pressure:1. Remove the cap from the valve on onetire, then firmly press the tire gauge onto the valve.
2. Add air to reach the recommended air pressure. 3. Replace 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.
4. Visually inspect the tires to make sure
there are no nails or other objects embedded that could puncture the tireand cause an air leak.
5. Check the sidewalls to make sure there are no gouges, cuts, bulges or otherirregularities.
6. Repeat this procedure for each tire, including the spare.
NOTE
•If you overfill the tire, release air by pushing on the metal stem in the cen-ter of the valve. Then recheck thepressure with your tire gauge.
• Some spare tires require higher infla-tion pressure than the other tires. Con-sult the tire inflation pressure table,see Tire inflation – pressure table(p. 300) or see the inflation pressureplacard.

Information on the sidewall
Federal law mandates that tire manufacturers place standardized information on the side-wall of all tires (see the illustration). The following information is listed on the tire sidewall: The tire designation:
NOTE
Please be aware that the following tire designation is an example only and that
this particular tire may not be available onyour vehicle.
1. 215: the width of the tire (in millimeters)
from sidewall edge to sidewall edge. The larger the number, the wider the tire.
2. 65: The ratio of the tire's height to its
width in percent.
3. R: Radial tire (the designation RF and the
symbol indicate that the vehicle is
equipped with optional self-supporting run flat tires 3
.
4. 15: The diameter of the wheel rim (in
inches).
5. 95: The tire's load index. In this example,
a load index of 95 equals a maximum load of 1521 lbs (690 kg).
6. H: The tire's speed rating, or the maxi-
mum speed at which the tire is designedto be driven for extended periods of time,carrying a permissible load for the vehi-cle, and with correct inflation pressure.For example, H indicates a speed ratingof 130 mph (210 km/h).
NOTE
The tire's load index and speed rating may not appear on the sidewall because theyare not required by law.

Snow tires/studded tires4
Owners who live in or regularly commute through areas with sustained periods of snowor icy driving conditions are strongly advisedto fit suitable winter tires to help retain thehighest degree of traction.
Tires for winter use:
•
It is important to install winter tires on all four wheels to help retain traction duringcornering, braking, and accelerating. Fail-ure to do so could reduce traction to anunsafe level or adversely affect handling.
• Do not mix tires of different design as thiscould also negatively affect overall tireroad grip.
• Winter tires wear more quickly on dryroads in warm weather. They should beremoved when the winter driving seasonhas ended.
• Studded tires should be run-in 300 – 600 miles (500 – 1000 km) during whichthe vehicle should be driven as smoothlyas possible to give the studs the opportu-nity to seat properly in the tires. The tiresshould have the same rotational directionthroughout their entire lifetime.
NOTE
Please consult state or provincial regula- tions restricting the use of studded wintertires before installing such tires.
Tire pressure monitoring - introduction
Volvo provides two different systems to moni- tor tire pressure: Tire Pressure MonitoringSystem (TPMS) or Tire Monitor.
Determining which tire monitoring system is in your vehicle
To see which system is installed in your vehi- cle, press the
MY CAR button on the center
console. Go to
SettingsCar settings.
• If your vehicle has a menu called
Tire
monitoring, see Tire Monitor - introduc-
tion (p. 310).
• If your vehicle has a menu called
Tire
pressure, see Tire Pressure Monitoring
System (TPMS) – general information (p. 306).
IntroductionEach 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 hasbeen equipped with a tire pressure monitor-ing system that illuminates a low tire pressure telltale (
) when one or more of your tires
is significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates,you should stop and check your tires as soonas possible, and inflate them to the properpressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead totire failure. Under-inflation also reduces fuelefficiency and tire tread life, and may affectthe vehicle's handling and stopping ability.Please note that a tire pressure monitoringsystem is not a substitute for proper tiremaintenance, and it is the driver's responsi-bility to maintain correct tire pressure, even ifunder-inflation has not reached the level totrigger illumination of the system's low tirepressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate whenthe system is not operating properly. Themonitoring system's malfunction indicator iscombined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minuteand then remain continuously illuminated.This sequence will continue upon subsequentvehicle start-ups as long as the malfunction

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
USA – FCC ID: KR5S180052050 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.
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 forapproximately 1 minute and then remain illuminated.
Tire press. syst Service
required will be displayed.

Tire Pressure Monitoring System (TPMS) – recalibrating
In certain cases, it may be necessary to recali- brate TPMS to conform to Volvo's recom-mended tire inflation pressures (see the infla-tion pressure table in Tire inflation – pressuretable (p. 300)), for example, if higher inflationpressure is necessary when transportingheavy loads, etc.
Recalibrating TPMS (Canadian models
only)*
This is done in the vehicle's menu system. To recalibrate:
1. Switch off the engine.
2. Inflate the tires to the desired pressure and put the ignition in mode I or II (see
Ignition modes (p. 79) for additional infor- mation).
3. Press the MY CAR key in the center con-
sole control panel and select

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.
