General information
Economical driving conserves natural
resources
Better driving economy may be obtained by thinking ahead, avoiding rapid starts andstops and adjusting the speed of your vehicleto immediate traffic conditions. 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.
• 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 trunk open: Driving with
the trunk open could lead to poisonous exhaust gases entering the passengercompartment. If the trunk must be keptopen for any reason, proceed as follows:
• 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.
Weight distribution affects handlingAt 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 alterwith the vehicle load. The heavier the load inthe trunk, the less the tendency to under-steer.
Handling, roadholdingVehicle load, tire design and inflation pres-sure all affect vehicle handling. Therefore,check that the tires are inflated to the recom-mended pressure according to the vehicleload. See the "Tire pressure" section. Loadsshould be distributed so that capacity weight

Introduction
Volvo recommends the use of Volvo trailer hitches that are specially designed for thevehicle.
NOTE
See page 359 for the maximum trailer and tongue weights recommended by Volvo.
•Observe the legal requirements of the state/province in which the vehicles are
• All Volvo models are equipped withenergy-absorbing shock-mounted bump-ers. Trailer hitch installation should notinterfere with the proper operation of thisbumper system.
Trailer towing does not normally present any particular problems, but take into considera-tion: • Increase tire pressure to recommended full pressure. See the tire inflation tableon page 293.
• When your vehicle is new, avoid towingheavy trailers during the first 620 miles(1,000 km).
• Maximum speed when towing a trailer:50 mph (80 km/h).
• Engine and transmission are subject toincreased loads. Therefore, engine cool-ant temperature should be closely watched when driving in hot climates orhilly terrain. Use a lower gear and turn offthe air conditioner if the temperaturegauge needle enters the red range.
• If the automatic transmission begins tooverheat, a message will be displayed inthe text window.
• Avoid overload and other abusive opera-tion.
• Hauling a trailer affects handling, durabil-ity, and economy.
• It is necessary to balance trailer brakeswith the towing vehicle brakes to providea safe stop (check and observe state/local regulations).
• Do not connect the trailer's brake systemdirectly to the vehicle's brake system.
• More frequent vehicle maintenance isrequired.
• Remove the ball holder when the hitch isnot being used.
WARNING
• Bumper-attached trailer hitches must not be used on Volvos, nor shouldsafety chains be attached to thebumper.
• Trailer hitches attaching to the vehiclerear axle must not be used.
• Never connect a trailer's hydraulicbrake system directly to the vehiclebrake system, nor a trailer's lightingsystem directly to the vehicle lightingsystem. Consult your nearest author-ized Volvo retailer for correct installa-tion.
• When towing a trailer, the trailer'ssafety wire must be correctly fastenedto the hole or hook provided in thetrailer hitch on the vehicle. The safetywire should never be fastened to orwound around the drawbar ball.

process. The temporary spare

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
G021829
The tires have wear indicator strips running across or parallel to the tread. The letters TWI
are printed on the side of the tire. Whenapproximately 1/16" (1.6 mm) is left on thetread, these strips become visible and indi-cate that the tire should be replaced. Tires with 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 tire inflation table on page 293.
• 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
G021778
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.
• Incorrectly mounted tires impair the car'sbraking properties and ability to forceaside rain, snow and slush.

Tire inflation placard
Tire inflationCheck tire inflation pressure regularly. See the tire inflation table on page 293. A tire inflation pressure placard is also located onthe driver's side B-pillar (the structural mem-ber at the side of the vehicle, at the rear ofthe driver's door opening). This placard indi-cates the designation of the factory-mountedtires on your vehicle, as well as load limitsand 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 fromthe tires occurs naturally and tire pres-sure fluctuates with seasonal changesin temperature. Always check tirepressure regularly.
•
Use a tire gauge to check the tire inflation pressure, including the spare, at leastonce a month and before long trips. Youare strongly urged to buy a reliable tirepressure gauge, as automatic service sta-tion gauges may be inaccurate.
• Use the recommended cold inflationpressure for optimum tire performanceand wear.
• Under-inflation or over-inflation maycause uneven 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 ofvehicle control and increased risk ofinjury.
• Under-inflated tires reduce the loadcarrying capacity of your vehicle.
When weather temperature changes occur, tire inflation pressures also change. A 10-degree temperature drop causes a corres-ponding drop of 1 psi (7 kPa) in inflation pres-sure. Check your tire pressures frequentlyand adjust them to the proper pressure,which can be found on the vehicle's tire infor-mation placard or certification label.
Checking tire pressure
Cold tiresInflation pressure should be checked when the tires are cold. The 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 pumping 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 onpage 293 or see the inflation pressureplacard.

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 1
. See page 313 for more
information about these tires).
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.
7. M+S or M/S = Mud and Snow, AT = All
Terrain, AS = All Season
8. U.S. DOT Tire Identification Number (TIN)
: This begins with the letters "DOT"
and indicates that the tire meets all fed- eral standards. The next two numbers orletters are the plant code where it wasmanufactured, the next two are the tiresize code and the last four numbers rep-resent the week and year the tire wasbuilt. For example, 1510 means that thetire was manufactured during week 15 of2010. The numbers in between are mar-keting codes used at the manufacturer'sdiscretion. This information helps a tiremanufacturer identify a tire for safetyrecall purposes.
9. Tire Ply Composition and Material Used
: Indicates the number of plies indi-
cates or the number of layers of rubber- coated fabric in the tire tread and side-wall. Tire manufacturers also must indi-cate the ply materials in the tire and thesidewall, which include steel, nylon, poly-ester, and others.

Maximum Load : Indicates the maximum
load in pounds and kilograms that can be carried by the tire. Refer to the vehicle'stire information placard located on the B-Pillar for the correct tire pressure for yourvehicle.
11. Treadwear, Traction, and Temperature grades
: see page 299 for more informa-
tion.
12. Maximum permissible inflationpressure:
the greatest amount of air
pressure that should ever be put in the tire. This limit is set by the tire manufac-turer.
