Driving in cold weather
Check your vehicle before the approach of cold weather. The following advice is worth noting:
• Make sure that the engine cool- ant (p. 331) contains 50 percent anti-freeze. Any other mixture will reducefreeze protection. This gives protectionagainst freezing down to –31 °F (–35 °C).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.
• Try to keep the fuel tank well filled – thishelps prevent the formation of condensa-tion in the tank. In addition, in extremelycold weather conditions it is worthwhileto add fuel 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 greaterduring the winter since the windshieldwipers, lighting, etc., are used moreoften. Moreover, the capacity of the bat-tery decreases as the temperature drops.In very cold weather, a poorly chargedbattery can freeze and be damaged. It is therefore advisable to check the state ofcharge more frequently and spray an anti-rust oil on the battery posts.
• Volvo recommends the use of snow tireson all four wheels for winter driving, seeSnow tires/studded tires (p. 305).
• To prevent the washer fluid (p. 344)reser-voir from freezing, add washer solventscontaining antifreeze. This is importantsince dirt is often splashed on the wind-shield during winter driving, requiring thefrequent use of the washers and wipers.Volvo Washer Solvent should be dilutedas follows: Down to 14 °F (–10 °C): 1 partwasher solvent and 4 parts water Downto 5 °F (–15 °C): 1 part washer solventand 3 parts water Down to 0 °F (–18 °C):1 part washer solvent and 2 parts waterDown to –18 °F (–28 °C): 1 part washersolvent and 1 part water.
• Use Volvo Teflon Lock Spray in the locks.
• Avoid using de-icing sprays as they cancause damage to the locks.

Refueling – fuel requirements
Volvo recommends the use of detergent gas- oline to control engine deposits.
Deposit control gasoline (detergentadditives)
Detergent gasoline is effective in keepinginjectors and intake valves clean. Consistentuse of deposit control gasolines will helpensure good drivability and fuel economy. Ifyou are not sure whether the gasoline con-tains deposit control additives, check with theservice station operator.
NOTE
Volvo does not recommend the use of external fuel injector cleaning systems.
Unleaded fuelEach Volvo has a three-way catalytic con- verter and must use only unleaded gasoline.U.S. and Canadian regulations require thatpumps delivering unleaded gasoline belabeled "UNLEADED". Only these pumpshave nozzles which fit your vehicle's fillerinlet. It is unlawful to dispense leaded fuelinto a vehicle labeled "unleaded gasolineonly". Leaded gasoline damages the three-way catalytic converter and the heated oxy-gen sensor system. Repeated use of leadedgasoline will lessen the effectiveness of theemission control system (p. 279) and could result in loss of emission warranty coverage.State and local vehicle inspection programswill make detection of misfueling easier, pos-sibly resulting in emission test failure for mis-fueled vehicles.
NOTE
Some U.S. and Canadian gasolines con- tain an octane enhancing additive calledmethyl-cyclopentadienyl manganese tri-carbonyl (MMT). If such fuels are used,your Emission Control System perform-ance may be affected, and the CheckEngine Light (malfunction indicator light)located on your instrument panel maylight. If this occurs, please return yourvehicle to a trained and qualified Volvoservice technician for service.
Gasoline containing alcohol and ethers, "Oxygenated fuels"
Some fuel suppliers sell gasoline containing "oxygenates" which are usually alcohols orethers. In some areas, state or local lawsrequire that the service pump be marked indi-cating use of alcohols or ethers. However,there are areas in which the pumps areunmarked. If you are not sure whether there isalcohol or ethers in the gasoline you buy,check with the service station operator. Tomeet seasonal air quality standards, someareas require the use of "oxygenated" fuel.
Volvo allows the use of the following "oxy-genated" fuels; however, the octane rat-ings (p. 276) listed must still be met.
Alcohol – EthanolFuels containing up to 10% ethanol by vol- ume may be used. Ethanol may also be refer-red to as Ethyl alcohol, or "Gasohol". Ethers – MTBE: Fuels containing up to 15% MTBE may be used.
MethanolDo not use gasolines containing methanol(methyl alcohol, wood alcohol). This practicecan result in vehicle performance deteriora-tion and can damage critical parts in the fuelsystem. Such damage may not be coveredunder the New Vehicle Limited Warranty.

G028920
Typical pump octane label
NOTE
Vehicles equipped with the high perform- ance 4-cylinder engines (B4204T9 and B4204T10) require premium fuel 18
.
TOP TIER Detergent GasolineVolvo endorses the use of “TOP TIER Deter- gent Gasoline” where available to help main-tain engine performance and reliability. TOPTIER Detergent Gasoline meets a new stand- ard jointly established by leading automotivemanufactures to meet the needs of today’sadvanced engines. Qualifying gasoline retail-ers (stations) will, in most cases, identify theirgasoline as having met the “TOP TIER Deter-gent Gasoline” standards.
NOTE
Information about TOP TIER Detergent Gasoline is available atwww.toptiergas.com.
Demanding drivingIn demanding driving conditions, such as operating the vehicle in hot weather, towing atrailer, or driving for extended periods athigher altitudes than normal, it may be advis-able to switch to higher octane fuel (91 orhigher) or to change gasoline brands to fullyutilize your engine's capacity, and for thesmoothest possible operation.
NOTE
When switching to higher octane fuel or changing gasoline brands, it may be nec-essary to fill the tank more than oncebefore a difference in engine operation isnoticeable.
Fuel FormulationsDo not use gasoline that contains lead as a knock inhibitor, and do not use lead addi-tives. Besides damaging the exhaust emis-sion control systems on your vehicle, leadhas been strongly linked to certain forms ofcancer. Many fuels contain benzene as a solvent. Unburned benzene has been strongly linkedto certain forms of cancer. If you live in anarea where you must fill your own gas tank,take precautions. These may include:
• standing upwind away from the filler noz- zle while refueling
• refueling only at gas stations with vaporrecovery systems that fully seal themouth of the filler neck during refueling
• wearing neoprene gloves while handling afuel filler nozzle.
Use of AdditivesWith the exception of gas line antifreeze dur- ing winter months, do not add solvents, thick-eners, or other store-bought additives to yourvehicle's fuel, cooling, or lubricating systems.Overuse may damage your engine, and someof these additives contain organically volatilechemicals. Do not needlessly expose yourselfto these chemicals.

Emission controls
Three-way catalytic converter
•Keep your engine properly tuned. Certain engine malfunctions, particularly involvingthe electrical, fuel or distributor ignitionsystems, may cause unusually high three-way catalytic converter temperatures. Donot continue to operate your vehicle ifyou detect engine misfire, noticeable lossof power or other unusual operating con-ditions, such as engine overheating orbackfiring. A properly tuned engine willhelp avoid malfunctions that could dam-age the three-way catalytic converter.
• Do not park your vehicle over combusti-ble materials, such as grass or leaves,which can come into contact with the hotexhaust system and cause such materialsto ignite under certain wind and weatherconditions.
• Excessive starter cranking (in excess ofone minute), or an intermittently firing orflooded engine can cause three-way cat-alytic converter or exhaust system over-heating.
• Remember that tampering or unauthor-ized modifications to the engine, theEngine Control Module, or the vehiclemay be illegal and can cause three-waycatalytic converter or exhaust systemoverheating. This includes: altering fuelinjection settings or components, alteringemission system components or location or removing components, and/or repea-ted use of leaded fuel.NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxy- gen content of the exhaust gases. Readingsare fed into a control module that continu-ously monitors engine functions and controlsfuel injection. The ratio of fuel to air into theengine is continuously adjusted for efficientcombustion to help reduce harmful emis-sions.

Economical driving
Better driving economy may be obtained by thinking ahead, avoiding rapid starts andstops and adjusting the speed of your vehicleto immediate traffic conditions.
Economical driving conserves natural resources
Observe the following rules:
• Bring the engine to normal operating tem- perature as soon as possible by drivingwith a light foot on the accelerator pedalfor the first few minutes of operation. Acold engine uses more fuel and is subjectto increased wear.
• Whenever possible, avoid using the vehi-cle for driving short distances. This doesnot allow the engine to reach normaloperating temperature.
• Drive carefully and avoid rapid accelera-tion and hard braking.
• Use the transmission's Drive (
D) position
as often as possible and avoid using kick-down.

• Using the engine's optional Eco func- tion20
can help improve fuel economy. For
additional information, see ECO* (p. 261).
• Using the transmission's Sport mode 21
may increase fuel consumption some- what. Use the transmission's Drive ( D)
position as often as possible. For addi-tional information about Sport mode, seeTransmission – Geartronic (p. 253).
• Do not exceed posted speed limits.
• Avoid carrying unnecessary items (extraload) in the vehicle.
• Maintain correct tire pressure. Check tirepressure regularly (when tires are cold).
• Remove snow tires when threat of snowor ice has ended.
• Note that roof racks, ski racks, etc,increase air resistance and also fuel con-sumption.
• At highway driving speeds, fuel consump-tion will be lower with the air conditioningon and the windows closed than with theair conditioning off and the windowsopen.
• Using the onboard trip computer's fuelconsumption modes can help you learnhow to drive more economically.
Other factors that decrease gas mileage are: •
Dirty air cleaner
• Dirty engine oil and clogged oil filter
• Dragging brakes
• Incorrect front end alignment
Some of the above mentioned items and oth-ers are checked at the standard maintenanceintervals.
WARNING
Driving with the tailgate open: Driving
with the tailgate open could lead to poi- sonous exhaust gases entering the pas-senger compartment. If the tailgate mustbe kept open for any reason, proceed asfollows: • Close the windows
• Set the ventilation system control to air flow to floor, windshield and side win-dows and the blower control to itshighest setting.
Handling and roadholdingAt the specified curb weight your vehicle has a tendency to understeer, which means thatthe steering wheel has to be turned morethan might seem appropriate for the curva-ture of a bend. This ensures good stabilityand reduces the risk of rear wheel skid.Remember that these properties can alter with the vehicle load. The heavier the load inthe cargo area, the less the tendency toundersteer. •
Vehicle load, tire design and inflation pressure all affect vehicle handling.Therefore, check that the tires are inflatedto the recommended pressure accordingto the vehicle load. Loads should be dis-tributed so that capacity weight or maxi-mum permissible axle loads are notexceeded.

Changing a wheel – spare wheel
Wheel changes should always be carried out correctly.
Spare tire
The spare tire in your vehicle2
is called a
"Temporary Spare". Recommended tire pressure (see the placard on the B-pillar or on the fuel filler door) shouldbe maintained irrespective of which positionon the vehicle the temporary spare tire isused on. In the event of damage to this tire, a new one can be purchased from your Volvo retailer.
WARNING
Current legislation prohibits the use of the "Temporary Spare" tire other than as atemporary replacement for a puncturedtire. It must be replaced as soon as possi-ble by a standard tire. Road holding andhandling may be affected with the "Tem-porary Spare" in use. Do not exceed50 mph (80 km/h).
CAUTION
The vehicle must not be driven with wheels of different dimensions or with a spare tireother than the one that came with the vehi-cle. The use of different size wheels canseriously damage your car's transmission.
Spare wheelThe spare wheel is only intended for tempo- rary use. Replace it with a normal wheel assoon as possible. The car's handling may bealtered by the use of the spare wheel. Thecorrect tire pressure for the spare wheel isstated in the tire pressure table, see Tire infla-tion – pressure table (p. 300) and in the tireinflation placard on the driver's side doorjamb at the rear of the driver's door opening.
WARNING
Current legislation prohibits the use of the “Temporary Spare” tire other than as atemporary replacement for a puncturedtire. It must be replaced as soon as possi-ble by a standard tire. Road holding andhandling may be affected with the “Tem-porary Spare” in use.
CAUTION
The vehicle must never be driven with more than one temporary spare wheel.
The spare wheel is located in the spare wheel well with the rim side down. There are twofoam blocks, one under the spare wheel andone over/inside. The upper one contains alltools. The same bolt runs through to secure the spare wheel and the foam blocks.

Loading specifications
Properly loading your vehicle will provide maximum return of vehicle design perform-ance. Before loading your vehicle, familiarize your- self with the following terms for determiningyour vehicle's weight ratings, with or withouta trailer, from the vehicle's Federal/CanadianMotor Vehicle Safety Standards (FMVSS/CMVSS) label, and the vehicle's tire informa-tion placard:
Curb weightThe weight of the vehicle including a full tankof fuel and all standard equipment. It doesnot include passengers, cargo, or optionalequipment.
Capacity weightAll weight added to the curb weight, includingcargo and optional equipment. When towing,trailer hitch tongue load is also part of cargoweight.
Permissible axle weightThe maximum allowable weight that can becarried by a single axle (front or rear). Thesenumbers are shown on the Federal/CanadianMotor Vehicle Safety Standards (FMVSS/CMVSS) label. The total load on each axlemust never exceed its maximum permissibleweight.
Gross vehicle weight (GVW)The vehicle's curb weight + cargo + passen-gers.
NOTE
•The location of the various labels in your vehicle, see Label information(p. 367).
• A table listing important weight limitsfor your vehicle, see Weights (p. 372).
Loading specifications – load limit
The load limit of your vehicle is the combined weight of the occupants and cargo.
Steps for Determining Correct Load
Limit
1. Locate the statement "the combined weight of occupants and cargo shouldnever exceed XXX pounds" on your vehi-cle's placard.
2. Determine the combined weight of the driver and passengers that will be ridingin your vehicle.
3. Subtract the combined weight of the driver and passengers from XXX kilo-grams or XXX pounds.
4. The resulting figure equals the available amount of cargo and luggage loadcapacity. For example, if the "XXX"amount equals 1400 lbs. and there will befive 150 lb. passengers in your vehicle,the amount of available cargo and lug-gage load capacity is 650 lbs. (1400 – 750 (5 × 150) = 650 lbs.)
5. Determine the combined weight of lug- gage and cargo being loaded on the vehi-cle. That weight may not safely exceedthe available cargo and luggage loadcapacity calculated in Step 4.

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

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
