HD Radio™
HD Radio is a brand name registered by the DTS,
Inc.3. They are the developer of a broadcastingtechnology called IBOC or In Band On Channel,which refers to the method of transmitting a digi-tal radio broadcast signal centered on the samefrequency as the FM station's present frequency.
Introduction
Display when the radio is receiving an HD Radio broad-cast (generic illustration)

NOTE
HD Radio volume may fade in and out attimes due to coverage limitations.
The IBOC system is referred to as a "hybrid"since it is both analog and digital. During hybridoperation, receivers still continue to receive theanalog (non-digital) signal. HD Radio receiversincorporate both modes of reception, where thereceiver will automatically switch to the analogsignal if the digital signal cannot be decoded oris lost by the receiver.
When you have tuned to an HD Radio station, the
symbol will appear in the infotainment sys-tem display. The symbol will be displayed in dif-ferent colors:
Grayed-out symbol: No HD Radio broad-cast reception
White symbol: the radio is actively receivingan HD broadcast
Orange symbol: the radio is receiving anHD broadcast with digital sound
More information about HD Radio and IBOC canbe found on DTS, Inc.'s website, www.dts.com.

A radio station's logo and album art can be dis-played. If a station opts to provide this informa-tion, it is broadcast once every 12 minutes, whichmeans that there may be a delay before thelogo/album art appear on the screen. The radiocan store 100 station logos so the next time theradio is tuned to the same station, the logo will

HD Radio™ limitations

Limitations
Main channel vs. sub-channels (FM only):The main channel is the only channel thatcan receive in hybrid mode (both digital andanalog). If a frequency has sub-channels,they are broadcast in digital mode only. Themain FM channel will be displayed as, forexample, "WRIF-FM HD1". The sub-FMchannels will be displayed as"WRIF-FMHD2", "WRIF-FM HD3", etc.
Reception coverage area: Due to currentIBOC transmitter power limitations, thereception coverage area in digital mode issomewhat more limited than the station'sanalog coverage area. Be aware that, like allradio transmission technology, terrain, time ofday, vegetation and buildings can have apositive or negative effect on radio reception.
Analog to digital/digital to analog blend-ing: Analog to digital blending will occur asthe signal strength reaches a preset thresh-old in the receiver. This will be noticeable infringe areas (areas with weak reception) andis normal.
NOTE
There may be a noticeable difference insound quality when a change from analogueto digital or digital to analogue occurs, suchas:
Volume increase or decrease
Equalizer settings, i.e., Bass/ Midrange/Treble cut or boost
Time alignment (Digital program materialin extreme cases can be as much as 8seconds behind the analogue). This willnoticeable as a "stuttering" effect.
The above items are dependant on thebroadcaster's equipment settings and donot indicate a fault in the vehicle's radioreceiver or antenna systems.

WHEELS AND TIRES

Tires
The function of the tires is to carry loads, providetraction on road surfaces, reduce vibrations andprotect the wheels from wear.
The tires significantly influence the vehicle's driv-ing characteristics. The type, dimensions, tirepressure and speed rating have a considerableimpact on how the vehicle performs.
Your vehicle is equipped with tires according tothe vehicle's tire information placard on the B-pil-lar (the structural member at the side of the vehi-cle, at the rear of the driver's door opening).

WARNING
A damaged tire could cause the driver to losecontrol of the vehicle.
CAUTION
Some Volvo models are equipped with anUltra High Performance tire and wheel com-bination designed to provide maximum drypavement performance with consideration forhydroplaning resistance. They may be moresusceptible to road hazard damage and,depending on driving conditions, may achievea tread life of less than 30,000 km (20,000miles). Even if this vehicle is equipped withVolvo's advanced AWD or stability system,these tires are not designed for winter driving,and should be replaced with winter tires whenweather conditions dictate.
The tires have good road holding characteristicsand offer good handling on dry and wet surfaces.It should be noted however that the tires havebeen developed to give these features on snow/ice-free surfaces.
Most models are equipped with "all-season" tires,which provide a somewhat higher degree of road-holding on slippery road surfaces than tires with-out the "all-season" rating. However, for optimalroadholding on icy or snow-covered roads, Volvorecommends snow tires on all four wheels.
When replacing tires, be sure that the new tiresare the same size designation, type (radial) andpreferably from the same manufacturer, on all
four wheels. Otherwise there is a risk of alteringthe vehicle's roadholding and handling characte-ristics.

Recommended tires
On delivery, the car is equipped with Volvo origi-
nal tires that have the VOL1 marking on the sideof the tires. These tires have been designed spe-cifically for your vehicle. It is therefore importantwhen replacing tires that the new tires have thissame marking to help maintain the vehicle's driv-ing characteristics, comfort and fuel consumption.

New tires
Tires are perishable goods. After a few years,they will begin to harden and their friction proper-ties will gradually deteriorate. Always replace tireswith the freshest tires possible. This is particularlyimportant for snow tires. A series of numbers is

imprinted on the sidewall of the tire. The last fourdigits in the series is the Department ofTransportation (DOT) stamp and indicates theweek and year the tire was manufactured. Thetire in the illustration has 0717 as the last fourdigits, which means it was manufactured week 7of 2017.

Tire age
Tires degrade over time, even when they are notbeing used. It is recommended that tires gener-ally be replaced after 6 years of normal service.Heat caused by hot climates, frequent high load-ing conditions or Ultra Violet (U.V.) exposure canaccelerate the aging process. The temporary
spare 2 should also be replaced at 6-year inter-vals, even if it has never been used. A tire withe.g., visible cracks or discoloration should bereplaced immediately.

Tire economy
Maintain correct tire pressure.
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.
Tire rotation
Your vehicle has no required tire rotation. Drivingstyle, tire pressure, climate and road conditionsaffect how quickly the tires age and exhibit signsof wear. Maintaining the correct tire pressurehelps keep tread wear evenly distributed.
To help prevent differences in tread depth andwear patterns forming on the tires, the front andrear wheels should be rotated, i.e. the front tiresmoved to the rear and the rear tires moved to thefront. Ideally, tire rotation should be done the firsttime after approximately 5000 km (ca3100 miles) and thereafter at 10,000 km(approx. 6200 miles) intervals.
If you have any questions regarding tread depth,Volvo recommends consulting an authorizedVolvo workshop. If significant differences in wear(> 1 mm difference in tread depth) between thetires have already occurred, the least worn tiresshould always be mounted on the rear wheels. Afront-wheel skid (understeer) is usually easier to
control than a rear-wheel skid (oversteer). If thefront wheels skid, the vehicle will continue in astraight line instead of the rear wheels skiddingto the side, which could cause you to completelylose control of the vehicle. It is therefore impor-tant that the rear wheels never lose grip beforethe front wheels.
Storing wheels and tires
When storing complete wheels (tires mounted onrims), they should be suspended off the floor orplaced on their sides on the floor.
Tires not mounted on rims should be stored ontheir sides or standing upright, but should not besuspended.

CAUTION
Tires should preferably be stored in a cool,dry, dark place, and should never be stored inclose proximity to solvents, gasoline, oils, etc.

Checking tire pressure
Correct inflation pressure helps improve drivingstability, save fuel and increase the service life ofthe tires.
Tire pressure decreases over time, which is nor-mal. Tire pressure also varies depending on theambient temperature. Driving on under-inflatedtires could cause the vehicle to overheat and leadto damage. Tire pressure affects traveling com-fort, road noise and driving characteristics.
Check the pressure in the tires every month. Usethe recommended inflation pressure for cold tiresfor optimal tire performance and wear. Under-inflated or over-inflated tires could cause uneventread wear.
Use an air pressure gauge and check the infla-tion pressure on all the tires, including the spare
tire4, at least once a month and before long trips.Volvo strongly recommends buying a reliable airpressure gauge, as the automatic gauges provi-ded at service stations may be inaccurate.

WARNING
Under-inflation is the most commoncause 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.

Cold tires
Inflation pressure should be checked when thetires are cold.
The tires are considered to be cold when theyhave the same temperature as the surrounding(ambient) air.
This temperature is normally reached after thevehicle has been parked for at least 3 hours.
After driving for approximately 1.6 km (1 mile),the tires are considered to be warm. If you needto drive longer than that to inflate the tires, checkand record the inflation pressure of the tires firstand inflate accordingly when you arrive at thepump.
When the ambient temperature changes, so doesthe inflation pressure. A 10-degree temperaturedrop causes a corresponding drop in inflationpressure of 1 psi (7 kPa). Check the inflationpressure of the tires regularly and adjust to the
correct pressure, which can be found on the vehi-cle's tire information placard or certification label.
If you check inflation pressure when the tires arewarm, you should never release air. The tiresbecome warm after driving and it is normal forwarm tires to have an inflation pressure abovethe recommended pressure for cold tires. A warmtire with an inflation pressure equal to or underthe recommended pressure for cold tires couldbe significantly under-inflated.

Adjusting tire pressure
Tire pressure decreases over time, which is nor-mal. The tire pressure must therefore beadjusted to maintain the recommended tire pres-sure.
Use the recommended inflation pressure for coldtires for optimal tire performance and wear.

NOTE
To help prevent incorrect inflation pressure,pressure should be checked when the tiresare cold. The tires are considered to be coldwhen they have reached the same tempera-ture as the ambient temperature (about 3hours after the vehicle was last driven). Afterdriving for a few kilometers, the tires will warmup and the pressure will increase.
1. Remove the valve cap from the tire and pressthe air pressure gauge firmly onto the valve.
2. Inflate the tire to the correct inflation pres-sure; see the tire pressure placard on thedriver's side B pillar for recommended pres-sures for factory-mounted tires.
3.Screw the valve cap back on.
NOTE
After inflating a tire, always replace thevalve cap to help prevent valve damagecaused by gravel, dirt, etc.
Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
4. Visually inspect the tire to make sure thereare no nails or other embedded objects thatcould puncture the tire and cause air leak-age.
5. Check the sidewalls to make sure there areno gouges, cuts, bulges or other irregulari-ties.
6.Repeat this procedure for each tire, including
the spare tire5.
NOTE
If you have overfilled the tire, release air bypushing on the metal stem in the center ofthe valve. Then recheck the pressure withyour tire gauge.
Some spare tires require higher inflation pres-sure than the other tires. Consult the tireinflation pressure table or the inflation pres-sure placard.

Tire pressure monitoring system*
The tire pressure monitoring system6 provides awarning symbol in the instrument panel if pres-sure is too low in one or more tires.
Symbol Explanation
This symbol illuminates to indicatelow inflation pressure.
If there is a system malfunction, theinflation pressure warning symbolwill flash for approximately oneminute and then glow steadily.
System description
The tire pressure monitoring system measuresdifferences in rotational speed between thewheels through the ABS system to determine ifthe tires are properly inflated. If inflation pressurein a tire is too low, its diameter (and consequentlyits rotational speed) changes. By comparing thetires with each other, the system can determine ifthe pressure in one or more tires is too low.

General information about the tire pressure
monitoring system
In the following description, the tire monitoringsystem is generally referred to as TPMS.
Each tire, including the spare (if provided)7
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 hasbeen equipped with a tire pressure monitoringsystem (TPMS) that illuminates a low tire pres-sure telltale when one or more of your tires issignificantly under-inflated. Accordingly, when thelow tire pressure telltale illuminates, you shouldstop and check your tires as soon as possible,and inflate 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 thatthe TPMS is not a substitute for proper tire main-tenance, and it is the driver's responsibility tomaintain correct tire pressure, even if under-infla-tion has not reached the level to trigger illumina-tion of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with aTPMS malfunction indicator to indicate when thesystem is not operating properly. The TPMS mal-function indicator is combined with the low tire
