Preparing for a long trip
It is important to have the vehicle's systems and equipment checked carefully before driv-ing long distances.
Check that
the engine is running properly and that fuel consumption is normal
there are no leaks (fuel, oil or other fluid)
the brake pedal is functioning properly
all lights are working
‒ adjust the head-
light height if the vehicle is carrying aheavy load
tire tread depth and air pressure are atcorrect levels. Change to snow tires whendriving in areas where there is a risk ofsnowy or icy roads
the start battery is sufficiently charged
the wiper blades are in good condition

Winter driving
It is important to check the vehicle before driving in cold/snowy conditions to makesure it can be driven safely.
Before the cold season arrives: Make sure the engine coolant contains 50% antifreeze. This mixture helps pro-tect the engine from frost erosion down toapprox. –35 °C (–31 °F). Do not mix dif-ferent types of antifreeze as this couldpose a health risk.
Keep the fuel tank well filled to preventcondensation from forming.
Check the viscosity of the engine oil. Oilwith low viscosity (thinner oil) improvescold-weather starting and reduces fuelconsumption when driving with a coldengine.
CAUTION
Low-viscosity oil should not be used with hard driving or in hot weather.
Check the condition and charge level of the start battery. Cold weather placesgreater demands on the start battery andreduces its capacity.
Use washer fluid containing antifreeze tohelp prevent ice from forming in thewasher fluid reservoir.
Slippery driving conditionsTo help optimize traction and roadholding,Volvo recommends using snow tires on allwheels whenever there is a risk of snow or iceon the road.
NOTE
Certain countries require use of winter tires by law. Not all countries permit the use ofstudded tires.
Practice driving on slippery surfaces under controlled conditions to learn how the vehiclereacts.

NOTE
When switching to higher octane fuel or changing gasoline brands, it may be neces-sary to fill the tank more than once before adifference in engine operation is noticea-ble.
Fuel FormulationsDo not use gasoline that contains lead or man- ganese as a knock inhibitor, and do not uselead additives. Besides damaging the exhaustemission 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 linked tocertain forms of cancer. If you live in an areawhere you must fill your own gas tank, takeprecautions. These may include: standing upwind away from the filler noz-zle while refueling
refueling only at gas stations with vaporrecovery systems that fully seal the mouthof 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.
WARNING
Never carry a cell phone that is
switched
on while refueling your vehicle. If the
phone rings, this may cause a spark that could ignite gasoline fumes, resulting in fireand injury.
WARNING
Carbon monoxide is a poisonous, colorless, and odorless gas. It is present in all exhaustgases. If you ever smell exhaust fumesinside the vehicle, make sure the passengercompartment is ventilated, and immedi-ately return the vehicle to a trained andqualified Volvo service technician for cor-rection.
Demanding drivingIn demanding driving conditions, such as when towing a trailer or driving in hot weather or for prolonged periods at high altitudes, it may be a good idea to switch to a higher- octane fuel (AKI
9
91 or higher) or to switch to
another brand of gasoline in order to fully uti- lize the vehicle's engine capacity and optimizetraction.

Audio, media and Internet
The audio and media system consists of a media player and a radio. A cellular phone canalso be connected through Bluetooth to usehands-free functions or play music in thevehicle. When the vehicle is connected to theInternet, it is also possible to use apps to playmedia.
Audio and media overview
The functions can be controlled using voice commands, the steering wheel keypad or thecenter display. The number of speakers andamplifiers varies depending on the audio sys-tem installed in the vehicle.
System updates
The audio and media system is continuously improved. It is recommended to download system updates as soon as they are available.

Sound settings
Sound reproduction quality is preset but can also be adjusted.
The system's volume is normally adjusted using the volume control below the center dis-play or the right-side steering wheel keypad.This applies, for example, when playing musicor the radio or during phone calls and activetraffic messages.
Sound reproductionThe audio system is precalibrated using digitalsignal processing. This calibration takes intoaccount speakers, amplifiers, passenger com-partment acoustics, listener position, etc. foreach combination of vehicle model and audiosystem. There is also a dynamic calibrationthat takes into account the volume control set-ting and the vehicle's speed.
Personal settingsDifferent settings are available in Top view under
SettingsSound depending on the
vehicle's sound system.
Premium Sound * (Bowers & Wilkins)
Tone - setting for e.g. bass, treble, equal-
izer, etc.

Balance - balance between right/left and
front/rear speakers.

System Volumes – adjusts volume in the
various systems of the car, e.g. Voice

WHEELS AND TIRES
520
TiresThe function of the tires is to carry loads, pro- vide traction on road surfaces, reduce vibra-tions and protect the wheels from wear.
The tires significantly influence the vehicle's driving characteristics. The type, dimensions,tire pressure and speed rating have a consid-erable impact on how the vehicle performs. 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).
WARNING
A damaged tire could cause the driver to lose control of the vehicle.
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 road haz-ard damage and, depending on drivingconditions, may achieve a tread life of lessthan 30,000 km (20,000 miles). Even ifthis vehicle is equipped with Volvo'sadvanced AWD or stability system, thesetires are not designed for winter driving,and should be replaced with winter tireswhen weather conditions 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 roadholding on slippery road surfa-ces than tires without the "all-season" rating.However, for optimal roadholding on icy orsnow-covered roads, Volvo recommendssnow tires on all four wheels. When replacing tires, be sure that the newtires 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 vehicle's roadholding andhandling characteristics.
Recommended tiresOn delivery, the car is equipped with Volvo original tires that have the VOL
1
marking on
the side of the tires. These tires have been designed specifically for your vehicle. It istherefore important when replacing tires thatthe new tires have this same marking to helpmaintain the vehicle's driving characteristics,comfort and fuel consumption.

Uniform Tire Quality GradingALL PASSENGER VEHICLE TIRES MUST CONFORM TO FEDERAL SAFETYREQUIREMENTS IN ADDITION TO THESEGRADES .
Quality grades can be found, where applica- ble, on the tire sidewall between the treadshoulder and maximum section width. Forexample: Treadwear 200 Traction AA Temperature A
TREADWEARThe treadwear grade is a comparative rating based on the wear rate of the tire when testedunder controlled conditions on a specifiedgovernment test course. For example, a tiregraded 150 would wear one and one half (1 ½)times as well on the government course as atire graded 100. The relative performance oftires depends upon the actual conditions oftheir use, however, and many depart signifi-cantly from the norm due to variation in drivinghabits, maintenance practices and differencesin road characteristics and climate.
TRACTIONThe traction grades, from highest to lowest,are AA, A, B, and C, as measured under con-trolled conditions on specified governmenttest surfaces of asphalt and concrete. A tiremarked C may have poor traction perform-ance.
WARNING
The traction grade assigned to this tire is based on braking (straight-ahead) tractiontests and is not a measure of cornering(turning) traction.
TEMPERATUREThe temperature grades are A (the highest), B, and C, representing the tire's resistance to thegeneration of heat and its ability to dissipateheat when tested under controlled conditionson a specified indoor laboratory test wheel.Sustained high temperature can cause thematerial of the tire to degenerate and reducetire life, and excessive temperature can lead tosudden tire failure. The grade C correspondsto a minimum level of performance that allpassenger vehicle tires must meet under theFederal Motor Safety Standard No. 109.Grades B and A represent higher levels of per-formance on the laboratory test wheel thanthe minimum required by law.
WARNING
The temperature grade for this tire is estab- lished for a tire that is properly inflated andnot overloaded. Excessive speed, under-inflation, or excessive loading, either sepa-rately or in combination, can cause heatbuildup and tire failure.
