Towing the vehicle Always check with state and local authorities before attempting to tow another vehiclebecause this type of towing is subject to regula-tions regarding maximum towing speed, lengthand type of towing device, lighting, etc.
1. With the remote key fully pressed into theignition slot 14
, press START/STOP ENGINE
for approximately 2 seconds to activate igni- tion mode II.
2. The remote key must remain in the ignition slot15
for the entire time that the vehicle is
being towed.
3. Keep the tow rope taut when the towing vehicle slows down by applying light pressure on the brake pedal. This will help prevent jar-ring movements of the vehicle being towed.
4. Be prepared to apply the brakes to stop the vehicle being towed.
CAUTION
General towing precautions:
• Please check with state and local author- ities before attempting this type of tow-ing, as vehicles being towed are subjectto regulations regarding maximum towingspeed, length and type of towing device,lighting, etc.
• If the vehicle's battery is dead, see Jumpstarting (p. 254) to provide current forreleasing the electric parking brake and to move the gear selector from the
P
position to N. If this is not possible, see
Transmission – shiftlock override (p. 259) for information about manually overridingthe shiftlock system to move the gear selector from P to N.
• Maximum speed: 50 mph (80 km/h). Do not exceed the maximum allowable tow-ing speed.
• Maximum distance with front wheels onground: 50 miles (80 km).
• The vehicle should only be towed in theforward direction.

Tires – tread wear indicator The tires have wear indicator strips running across or parallel to the tread.
G021829
The letters TWI are printed on the side of the tire.
When approximately 1/16" (1.6 mm) is left on the tread, these strips become visible and indi-cate that the tire should be replaced. Tires withless than 1/16" (1.6 mm) tread offer very poortraction. When replacing worn tires, it is recommended that the tire be identical in type (radial) and sizeas the one being replaced. Using a tire of thesame make (manufacturer) will prevent alterationof the driving characteristics of the vehicle.

A smooth driving style and correct inflation pres- sure can help prolong the tires' service life.
• Maintain correct tire pressure. The tire infla- tion table, see the tire inflation decal on thedriver's door opening.
• Avoid fast starts, hard braking and tirescreeching.
• Tire wear increases with speed.
• Correct front wheel alignment is very impor-tant.
• Unbalanced wheels impair tire economy anddriving comfort.
• Tires must maintain the same direction ofrotation throughout their lifetime.
• When replacing tires, the tires with the mosttread should be mounted on the rear wheelsto reduce the chance of oversteer duringhard braking.
• Hitting curbs or potholes can damage thetires and/or wheels permanently.

Changing a wheel – spare wheel Wheel changes should always be carried out correctly.
Spare tireA spare tire can be purchased for your vehicle as an accessory. Follow the instructions includedwith the spare tire regarding use and stowing inthe vehicle. See also Changing a wheel – remov-ing wheel (p. 293) for additional information.
Spare wheelThe following instructions only apply if you have purchased a temporary spare wheel * for your
vehicle. If there is no temporary spare wheel in your vehi- cle, please see Tire sealing system * – general
information (p. 314) for instructions on using the tire sealing system. The accessory temporary spare wheel is provided in a bag that must be securely strapped in placein the trunk while the vehicle is being driven. The spare wheel is only intended for temporary use. Replace it with a normal wheel as soon aspossible. The vehicle's handling may be alteredby the use of the spare wheel. The correct tirepressure is stated in the tire pressure table, seethe tire inflation decal on the driver's door open-ing.Turn the handle on the spare wheel bag in toward the rear seat. Secure the stitched straphooks in the loading eyelets. Secure the longstrap in one of the loading eyelets, wrap the straparound the spare wheel and through the lowerhandle. Secure the short strap on the long strap.Secure in the other loading eyelet and tighten.
WARNING
Current legislation prohibits the use of the “Temporary Spare” tire other than as a tempo-rary replacement for a punctured tire. It mustbe replaced as soon as possible by a stand-ard tire. Road holding and handling may beaffected with the “Temporary Spare” in use.
CAUTION
The vehicle must never be driven with more than one temporary spare wheel.

Tire inflation placard
Tire inflationSee the tire inflation decal on the driver's door opening. This decal indicates the designation ofthe factory-mounted tires on your vehicle, as wellas load limits and inflation pressure.
NOTE
• The placards shown indicate inflation pressure for the tires installed on thevehicle at the factory only.
• A certain amount of air seepage from thetires occurs naturally and tire pressurefluctuates with seasonal changes in tem-perature. Always check tire pressure reg-ularly.
•Use a tire gauge to check the tire inflation pressure, including the spare 2
, at least once
a month and before long trips. You are strongly urged to buy a reliable tire pressuregauge, as automatic service station gaugesmay be inaccurate.
• Use the recommended cold inflation pres-sure for optimum tire performance and wear.
• Under-inflation or over-inflation may causeuneven treadwear patterns.

WARNING
•Under-inflation is the most common cause of tire failure and may result insevere tire cracking, tread separation, or"blow-out," with unexpected loss of vehi-cle control and increased risk of injury.
• Under-inflated tires reduce the load car-rying capacity of your vehicle.
When weather temperature changes occur, tireinflation pressures also change. A 10-degreetemperature drop causes a corresponding dropof 1 psi (7 kPa) in inflation pressure. Check yourtire pressures frequently and adjust them to theproper pressure, which can be found on the vehi-cle's tire information placard or certification label.

Tire inflation – checking pressure
Inflation pressure should be checked when the tires are cold.
Cold tires
The tires are considered to be cold when they have the same temperature as the sur-rounding (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 be hot. If youhave to drive farther than this distance to pumpyour tire(s), check and record the tire pressurefirst and add the appropriate air pressure whenyou get to the pump. If checking tire pressure when the tire is hot, never "bleed" or reduce air pressure. The tiresare hot from driving and it is normal for pressuresto increase above recommended cold pressures.A hot tire at or below recommended cold inflationpressure could be significantly under-inflated.
To check inflation pressure:
1. Remove the cap from the valve on one tire, then firmly press the tire gauge onto the valve.
2. Add air to reach the recommended air pres- sure. 3. Replace the valve cap.
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.
4. Visually inspect the tires to make sure there
are no nails or other objects embedded that could puncture the tire and cause an air leak.
5. Check the sidewalls to make sure there are no gouges, cuts, bulges or other irregulari-ties.
6. Repeat this procedure for each tire, including the spare 3
.
NOTE
• If you overfill the tire, release air by push- ing on the metal stem in the center of thevalve. Then recheck the pressure withyour tire gauge.
• Some spare tires (available as an acces-sory) require higher inflation pressurethan the other tires. Consult the tire infla-

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 4
.
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 maximum
speed at which the tire is designed to bedriven for extended periods of time, carryinga permissible load for the vehicle, and withcorrect inflation pressure. For example, Hindicates a speed rating of 130 mph(210 km/h).
NOTE
The tire's load index and speed rating may not appear on the sidewall because they arenot required by law.
7. M+S or M/S = Mud and Snow, AT = All Ter-
rain, AS = All Season
8. U.S. DOT Tire Identification Number (TIN) : This begins with the letters "DOT" and
indicates that the tire meets all federalstandards. The next two numbers or lettersare the plant code where it was manufac-tured, the next two are the tire size code andthe last four numbers represent the weekand year the tire was built. For example,1510 means that the tire was manufacturedduring week 15 of 2010. The numbers inbetween are marketing codes used at themanufacturer's discretion. This informationhelps a tire manufacturer identify a tire forsafety recall purposes.
9. Tire Ply Composition and Material Used :
Indicates the number of plies indicates or thenumber of layers of rubber-coated fabric inthe tire tread and sidewall. Tire manufactur-ers also must indicate the ply materials in thetire and the sidewall, which include steel,nylon, polyester, and others.
10. Maximum Load : Indicates the maximum
load in pounds and kilograms that can becarried by the tire. Refer to the vehicle's tireinformation placard located on the B-Pillarfor the correct tire pressure for your vehicle.
11. Treadwear, Traction, and Temperaturegrades : see Tire specifications – Uniform Tire Quality Grading (p. 304) for more infor-mation.
12. Maximum permissible inflation pressure: the greatest amount of air pressure that should ever be put in the tire. This limit is setby the tire manufacturer.

6. If your vehicle will be towing a trailer, load
from your trailer will be transferred to your vehicle. Consult this manual to determinehow this reduces the available cargo and lug-gage load capacity of your vehicle.
WARNING
• Exceeding the permissible axle weight, gross vehicle weight, or any other weightrating limits can cause tire overheatingresulting in permanent deformation orcatastrophic failure.
• Do not use replacement tires with lowerload carrying capacities than the tires thatwere original equipment on the vehiclebecause this will lower the vehicle's GVWrating. Use only tires with the correct loadcarrying capacity. Consult your Volvoretailer for information.

Snow tires/studded tires5
Owners who live in or regularly commute through areas with sustained periods of snow oricy driving conditions are strongly advised to fitsuitable winter tires to help retain the highestdegree of traction.
Tires for winter use:
• It is important to install winter tires on all four wheels to help retain traction during corner-ing, braking, and accelerating. Failure to doso could reduce traction to an unsafe level oradversely affect handling.
• Do not mix tires of different design as thiscould also negatively affect overall tire roadgrip.
• Winter tires wear more quickly on dry roadsin warm weather. They should be removedwhen the winter driving season has ended.
• Studded tires should be run-in 300 – 600 miles (500 – 1000 km) during whichthe vehicle should be driven as smoothly aspossible to give the studs the opportunity toseat properly in the tires. The tires shouldhave the same rotational direction through-out their entire lifetime.
NOTE
Please consult state or provincial regulations restricting the use of studded winter tiresbefore installing such tires.
Tire pressure monitoring - overview
Volvo provides two different systems to monitor tire pressure: Tire Pressure Monitoring System(TPMS) or Tire Monitor.
Determining which tire monitoring system is in your vehicle
To see which system is installed in your vehicle, 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 - introduction
(p. 307).
• If your vehicle has a menu called
Tire
pressure, see Tire Pressure Monitoring Sys-
tem (TPMS) – general information (p. 310).
Introduction
Each tire, including the spare 6
(if provided),
should be checked monthly when cold and infla- ted to the inflation pressure recommended by thevehicle manufacturer on the vehicle placard ortire inflation pressure label. (If your vehicle hastires of a different size than the size indicated onthe vehicle placard or tire inflation pressure label,you should determine the proper tire inflationpressure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoring

system that illuminates a low tire pressure telltale (
) when one or more of your tires is signifi-
cantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stopand check your tires as soon as possible, andinflate 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 that atire pressure monitoring system is not a substi-tute for proper tire maintenance, and it is the driv-er's responsibility to maintain correct tire pres-sure, even if under-inflation has not reached thelevel to trigger illumination of the system's lowtire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when thesystem is not operating properly. The monitoringsystem's malfunction indicator is combined withthe low tire pressure 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. System malfunctions may occur for a variety ofreasons, including the installation of replacementor alternate tires or wheels on the vehicle thatprevent the tire pressure monitoring system fromfunctioning properly. Always check the system's malfunction telltale after replacing one or more tires or wheels onyour vehicle to ensure that the replacement oralternate tires and wheels allow the system tocontinue to function properly.
NOTE
The system indicates low tire pressure but does not replace normal tire maintenance. Forinformation on correct tire pressure, pleaserefer to the tire inflation decal on the driver'sdoor opening or consult your Volvo retailer.
WARNING
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control of thevehicle.

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 tires with each otherit is possible to determine if one or more tires areunder inflated. When low inflation pressure is detected or if the system is not functioning properly, Tire Monitorwill light up the tire pressure warning light (
) (also referred to as a telltale) in the
instrument panel and will display one of several messages in the text window, for example:

pressure and recalibrate if necessary.
NOTE
If a malfunction occurs in the system, the tire pressure warning light will flash for approxi-mately 1 minute and then remain illuminated.
