Cold weather precautions

169
If you wish to check your vehicle before the approach of cold weather, the followingadvice is worth noting:
• Make sure that the engine coolant con- tains 50 percent antifreeze. Any othermixture will reduce freeze protection. Thisgives protection against freezing down to–31 °F (–35 °C). See section "Coolant".
• The use of "recycled" antifreeze is notapproved by Volvo. Different types ofantifreeze must not be mixed.
• Volvo recommends using only genuineVolvo antifreeze in your vehicle's radiator.Your Volvo retailer stocks plenty of Volvoengine coolant to protect your vehicleduring cold weather.
• Try to keep the
fuel tank well filled – this
prevents the formation of condensation inthe tank. In addition, in extremely coldweather conditions it is worthwhile to addfuel line de-icer before refueling.
• The viscosity of the engine oil is impor-tant. Oil with low viscosity (thinner oil)improves cold-weather starting as well asdecreasing fuel consumption while theengine is warming up. Full synthetic0W-30 oil is recommended for driving inareas with sustained low temperatures.
• The load placed on the
battery is greater
during the winter since the windshieldwipers, lighting, etc. are used more often. Moreover, the capacity of the batterydecreases as the temperature drops. Invery cold weather, a poorly charged bat-tery can freeze and be damaged. It istherefore advisable to check the state ofcharge more frequently and spray an anti-rust oil on the battery posts.
• Volvo recommends the use of
snow tires
on all four wheels for winter driving – seesection "Wheels and tires."
• To prevent the
washer fluid reservoir
from freezing, add washer solvents con-taining antifreeze (see page 224 for thelocation of the washer fluid reservoir).This is important since dirt is oftensplashed on the windshield during winterdriving, requiring the frequent use of thewashers and wipers. Volvo Washer Sol-vent should be diluted as follows:
• Down to 14 ° F (–10 ° C):
1 part washer
solvent and 4 parts water
• Down to 5 ° F (–15 ° C):
1 part washer
solvent and 3 parts water
• Down to 0 ° F (–18 ° C):
1 part washer
solvent and 2 parts water
• Down to –18 ° F (–28 ° C):
1 part washer
solvent and 1 part water
• Use Volvo Teflon Lock Spray in the locks.
NOTE
Avoid the use of de-icing sprays as they can cause damage to the locks.
W – Winter/Wet driving mode – enhanced vehicle traction
•Mode W will only function if the gear selector is in the (
D)rive position.
• Press the button at the base of the gearselector to engage/disengage this drivingmode.
• An LED in the button will light up to indi-cate that W is engaged and this will alsobe displayed in the instrument panel (seepage 58).
• This mode may be selected for starting/moving off on slippery roads.

Introduction
Your vehicle is equipped with tires according to the vehicle's tire information placard on theB-pillar (the structural member at the side ofthe vehicle, at the rear of the driver's dooropening).
CAUTION
Some Volvo models are equipped with an Ultra High Performance tire and wheelcombination designed to provide maxi-mum dry pavement performance with con-sideration for hydroplaning resistance.They may be more susceptible to roadhazard damage and, depending on drivingconditions, may achieve a tread life of lessthan 20,000 miles (30,000 km). Even if thisvehicle is equipped with Volvo’s advancedAWD or DSTC system, these tires are notdesigned for winter driving, and should bereplaced with winter tires when weatherconditions dictate.
The tires have good road holding characteris- tics and offer good handling on dry and wetsurfaces. It should be noted however that thetires have been developed to give these fea-tures on snow/ice-free surfaces. Most models are equipped with "all-season" tires, which provide a somewhat higherdegree of road holding on slippery surfacesthan tires without the "all-season" rating.However, for optimum road holding on icy orsnow-covered roads, we recommend suitablewinter tires on all four wheels. When replacing tires, be sure that the new tires are the same size designation, type(radial) and preferably from the same manu-facturer, on all four wheels. Otherwise there isa risk of altering the car's roadholding andhandling characteristics.
New Tires
Remember that tires are perishable goods. Asof 2000, the manufacturing week and year(Department of Transportation (DOT) stamp)will be indicated with 4 digits (e.g., 1513means that the tire illustrated was manufac-tured during week 15 of 2013).
Tire rotationYour vehicle has no required tire rotation. Tire wear is affected by a number of factors suchas tire inflation, ambient temperature, drivingstyle, etc.
NOTE
•
If the tires are rotated, they should only be moved from front to rear orvice versa. They should never be rota-ted left to right/right to left.
• Ideally, tire rotation should be done thefirst time after approximately 3,000miles (5,000 km) and thereafter at6,000-mile (10,000-km) intervals.Some customers find that tire rotationmay help to get extra mileage from tirelife.
• Tire rotation should only be performedif front/rear tire wear is fairly even andtread height is above 1/16" (1.6 mm).
Your Volvo retailer can also provide guidance based on your particular driving circumstan-ces.
Tire ageTires degrade over time, even when they arenot being used. It is recommended that tiresgenerally be replaced after 6 years of normalservice. Heat caused by hot climates, fre-

quent high loading conditions or Ultra Violet (U.V) exposure can accelerate the aging proc- ess. The temporary spare
1
should also be
replaced at 6-year intervals, even if it has never been used. A tire's age can be determined by the DOT stamp on the sidewall (see the illustration). A tire with e.g., visible cracks or discoloration should be replaced immediately.
Tread wear indicator
G020323
The tires have wear indicator strips running across or parallel to the tread. The letters TWI
are printed on the side of the tire. When approximately 1/16" (1.6 mm) is left on thetread, these strips become visible and indi-cate that the tire should be replaced. Tireswith less than 1/16" (1.6 mm) tread offer verypoor traction. When replacing worn tires, it is recommended that the tire be identical in type (radial) andsize as the one being replaced. Using a tire ofthe same make (manufacturer) will preventalteration of the driving characteristics of thevehicle.
Improving tire economy
•
Maintain correct tire pressure (see the inflation pressure table on page 183).
• Drive smoothly: avoid fast starts, hardbraking and tire screeching.
• Tire wear increases with speed.
• Correct front wheel alignment is veryimportant.
• Unbalanced wheels impair tire economyand driving comfort.
• Tires must maintain the same direction ofrotation throughout their lifetime.
• When replacing tires, the tires with themost tread should be mounted on therear wheels to reduce the chance of over-steer during hard braking. •
Hitting curbs or potholes can damage thetires and/or wheels permanently.
Summer and winter tires
G020325
The arrows shows the direction of rotation of the tire
• When switching between summer and winter tires, mark the tires to indicatewhere they were mounted on the car,e.g., LF = left front, RR = right rear
• Tires with tread designed to roll in onlyone direction are marked with an arrowon the sidewall.

•Tire information placard:
A placard
showing the OE (Original Equipment) tire sizes, recommended inflation pressure,and the maximum weight the vehicle cancarry.
• Tire Identification Number (TIN):
A
number on the sidewall of each tire pro-viding information about the tire brandand manufacturing plant, tire size anddate of manufacturer.
• Inflation pressure:
A measure of the
amount of air in a tire.
• Standard load:
A class of P-metric or
Metric tires designed to carry a maximumload at 35 psi [37 psi (2.5 bar) for Metrictires]. Increasing the inflation pressurebeyond this pressure will not increase thetires load carrying capability.
• Extra load:
A class of P-metric or Metric
tires designed to carry a heavier maxi-mum load at 41 psi [43 psi (2.9 bar) forMetric tires]. Increasing the inflation pres-sure beyond this pressure will notincrease the tires load carrying capability.
• kPa:
Kilopascal, a metric unit of air pres-
sure.
• PSI:
Pounds per square inch, a standard
unit of air pressure.
• B-pillar:
The structural member at the
side of the vehicle behind the front door. •
Bead area of the tire:
Area of the tire
next to the rim.
• Sidewall of the tire:
Area between the
bead area and the tread.
• Tread area of the tire:
Area of the perim-
eter of the tire that contacts the roadwhen mounted on the vehicle.
• Rim:
The metal support (wheel) for a tire
or a tire and tube assembly upon whichthe tire beads are seated.
• Maximum load rating:
a figure indicating
the maximum load in pounds and kilo-grams that can be carried by the tire. Thisrating is established by the tire manufac-turer.
• Maximum permissible inflation pres- sure:
the greatest amount of air pressure
that should ever be put in the tire. This limit is set by the tire manufacturer.
• Recommended tire inflation pressure: inflation pressure, established by Volvo, which is based on the type of tires thatare mounted on a vehicle at the factory.This information can be found on the tireinflation placard(s) located on the driver'sside B-pillar and in the tire inflation tablein this chapter.
• Cold tires:
The tires are considered to be
cold when they have the same tempera-ture as the surrounding (ambient) air. Thistemperature is normally reached after the vehicle has been parked for at least 3hours.

Snow chains
Snow chains can be used on your Volvo with the following restrictions:• Snow chains should be installed on front wheels only. Use only Volvo approvedsnow chains.
• If accessory, aftermarket or "custom"tires and wheels are installed and are of asize different than the original tires andwheels, chains in some cases CANNOTbe used. Sufficient clearances betweenchains and brakes, suspension and bodycomponents must be maintained.
• Some strap-on type chains will interferewith brake components and thereforeCANNOT be used.
• All Wheel Drive models: Snow chainsshould only be installed on the frontwheels.
• Certain size tires may not allow theassembly of snow chains/traction devi-ces.
Consult your Volvo retailer for additional snow chain information.CAUTION
• Check local regulations regarding the use of snow chains before installing.
• Always follow the chain manufactur-er's installation instructions carefully.Install chains as tightly as possible andretighten periodically.
• Never exceed the chain manufactur-er's specified maximum speed limit.(Under no circumstances should youexceed 31 mph (50 km/h)).
• Avoid bumps, holes or sharp turnswhen driving with snow chains.
• The handling of the vehicle can beadversely affected when driving withchains. Avoid fast or sharp turns aswell as locked wheel braking.
Snow tires, studded tires 1
Tires for winter use:
•
Owners who live in or regularly commute through areas with sustained periods ofsnow or icy driving conditions arestrongly advised to fit suitable winter tires to help retain the highest degree of trac-tion.
• It is important to install winter tires on allfour 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-in300-600 miles (500-1000 km) duringwhich the vehicle should be driven assmoothly as possible to give the studsthe opportunity to seat properly in thetires. The tires should have the samerotational direction throughout their entirelifetime.NOTE
Please consult state or provincial regula- tions restricting the use of studded wintertires before installing such tires.

Repeat steps 1-3 to turn TPMS on again.
Self-supporting run flat tires (SST)*
Self-supporting run flat tires are available as optional equipment. The vehicle must beequipped with the Tire Pressure MonitoringSystem (TPMS) if tires of this type are instal-led. 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 not more than 50 mph (80 km/h). The tire shouldbe replaced as soon as possible. Drive carefully; it may be difficult to determine which tire is damaged. To find the damagedtire, check the inflation pressure in all fourtires.
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 TPMS.
• Do not drive faster than 50 mph(80 km/h) if TPMS indicates that a tirehas lost inflation pressure.
• 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.

Owner maintenance
Periodic maintenance requirements and inter- vals are described in your vehicle's Warrantyand Service Records Information booklet. The following points can be carried out between the normally scheduled maintenanceservices.
Each time the vehicle is refueled
•Check the engine oil level
• Clean the windshield, windshield wipers, headlights, and tail lights
Monthly
•Check cold tire pressure in all tires.Inspect the tires for wear.
• Check that engine coolant and other fluidlevels are between the indicated "
min"
and " max" markings.
• Clean interior glass surfaces with a glasscleaner and soft paper towels.
• Wipe driver information displays with asoft cloth.
• Visually inspect battery terminals for cor-rosion. Corrosion may indicate a looseterminal connector, or a battery near theend of its useful service life. Consult atrained and qualified Volvo service techni-cian for additional information.
As needed
•
Wash the vehicle, including the undercar-riage, to reduce wear that can be causedby a buildup of dirt, and corrosion thatcan be caused by salt residues.
• Clean leaves and twigs from air intakevents at the base of the windshield, andfrom other places where they may collect.

Emission inspection readiness
What is an Onboard Diagnostic System
(OBD II)?
OBD II is part of your vehicle's computerized engine management system. It stores diag-nostic information about your vehicle's emis-sion controls. It can light the Check Enginelight (MIL) if it detects an emission control"fault." A "fault" is a component or systemthat is not performing within an expectedrange. A fault may be permanent or tempo-rary. OBD II will store a message about anyfault.
How do states use OBD II for emission
inspections?
Many states connect a computer directly to avehicle's OBD II system. The inspector can then read "faults." In some states, this type ofinspection has replaced the tailpipe emissiontest.
How can my vehicle fail OBD II emission
inspection?
Your vehicle can fail OBD II emission inspec-tion for any of the following reasons.
• If your Check Engine (MIL) light is lit, your vehicle may fail inspection.
• If your vehicle's Check Engine light waslit, but went out without any action onyour part, OBD II will still have a recordedfault. Your vehicle may pass or fail,depending on the inspection practices inyour area.
• If you had recent service that requireddisconnecting the battery, OBD II diag-nostic information may be incompleteand "not ready" for inspection. A vehiclethat is not ready may fail inspection.
How can I prepare for my next OBD II
emission inspection?
• If your Check Engine (MIL) light is lit – orwas lit but went out without service, haveyour vehicle diagnosed and, if necessary,serviced by a qualified Volvo technician.
• If you recently had service for a lit CheckEngine light, or if you had service thatrequired disconnecting the battery, aperiod of driving is necessary to bring the
