CauseAction
The area of the windshield in front of the camera/radar sensor is dirty or covered by ice or snow. Clean the windshield in front of the camera/radar sensor and remove dirt, ice andsnow.
Thick fog, heavy rain or snow is blocking the radar signals or thecamera's range of visibility. No action. Heavy precipitation may sometimes prevent the camera/radar sensor fromfunctioning.
Water or snow is spraying/swirling up and blocking the radar signalsor the camera's range of visibility. No action. Very wet or snow-covered roads may sometimes prevent the camera/radar sensor from functioning.
There is dirt between the inside of the windshield and the camera/radar sensor. Consult a workshop to have the area of the windshield on the inside of the camera'scasing cleaned. An authorized Volvo workshop is recommended.
Bright sunlight No action. The camera/radar sensor will reset automatically when lighting conditionsimprove.
NOTE
Keep the windshield in front of the camera and radar unit clean.
High temperaturesIf the temperature in the passenger compartment is very high, the camera/radar sensor will switchoff temporarily for approx. 15 minutes after theengine is started to protect its electronic compo-nents. When the temperature has cooled suffi-ciently, the camera/radar sensor will automati-cally restart.
Damaged windshield
CAUTION
If there are cracks, scratches or stone chips on the windshield in front of any of the cam-era and radar unit "windows" and this coversan area of about 0.5 × 3.0 mm(0.02 × 0.12 in.) or more, contact a workshopto have the windshield replaced – an author-ized Volvo workshop is recommended. Failure to take action could result in reduced performance for the driver support systemsthat use the camera and radar unit.
It could cause functions to be reduced, deac- tivated completely or produce an incorrectfunction response. To avoid the risk of loss of function, malfunc- tion or reduced function of the driver supportsystems that use the radar unit, the followingalso apply:
• Volvo advises
against repairing cracks,
scratches or stone chips in the area infront of the camera and radar unit – theentire windshield should instead bereplaced.
• Before replacing the windshield, contactan authorized Volvo workshop to verify

Blind sectors
There are "blind" sectors between the cameras' fields of vision.
With 360° view selected, objects/obstacles may not be detected if they are located in the "joints"where the edges of the individual camera viewsmeet.
WARNING
Even if it seems as though only a fairly small section of the screen image is obstructed, thismay mean that a relatively large sector is hid-den and obstacles there may not be detecteduntil they are very near the vehicle.
Defective cameraIf a camera sector is dark and contains this symbol, this indi-cates that the camera is notfunctioning properly. See the following illustration for an example.
The vehicle's left-side camera is malfunctioning.
Dark camera sector
A dark camera sector may also be displayed in the following situations, but without the defective
camera symbol:
• a door is open
• the tailgate is open
• a rearview mirror is folded in
Lighting conditionsThe camera image is automatically adjusted according to the current lighting conditions. This means that the brightness and quality of theimage may vary slightly. Poor lighting conditionsmay result in reduced image quality.

Fuel consumption is increased at high speeds - air resistance increases with speed.
• Remove unnecessary items from the vehicle- the heavier the load, the higher the fuelconsumption.
• Maintain the correct pressure in the tires andcheck pressure regularly.
• The type of tires used could affect fuel con-sumption - consult a retailer for advice onsuitable tires.
• Do not use winter tires after the winter sea-son has ended.
• Roof loads increase air resistance andincrease fuel consumption. Remove roofboxes, ski racks, etc. that are not in use.
• Avoid driving with the windows open.
• Using the trip computer's fuel consumptionindicators can help you learn how to drivemore economically.
Other factors that decrease fuel
consumption
• Dirty air cleaner.
• Dirty engine oil and clogged oil filter.
• Incorrect front-end alignment.
• Incorrect wheel alignment.
Some of the above items and others are checked as part of Volvo's standard maintenance sched-ule.

WARNING
Carbon monoxide is a poisonous, colorless, and odorless gas. It is present in all exhaustgases. If you ever smell exhaust fumes insidethe vehicle, make sure the passenger com-partment is ventilated, and immediately returnthe vehicle to a trained and qualified Volvoservice technician for correction.
Demanding drivingIn demanding driving conditions, e.g. when driving in a hot climates, driving with a trailer or drivingfor longer periods at higher altitudes (mountainlandscapes) than normal, it is recommended switching to a higher octane fuel than AKI 916
or
changing gasoline brand to take full advantage of your car's engine capacity and obtain the opti-mum driving force.

Emission controls
Three-way catalytic converter
•Keep your engine properly tuned. Certain engine malfunctions, particularly involving theelectrical, fuel or distributor ignition systems,may cause unusually high three-way catalyticconverter temperatures. Do not continue tooperate your vehicle if you detect enginemisfire, noticeable loss of power or otherunusual operating conditions, such as engineoverheating or backfiring. A properly tunedengine will help avoid malfunctions thatcould damage the three-way catalytic con-verter.
• Do not park your vehicle over combustiblematerials, such as grass or leaves, which cancome into contact with the hot exhaust sys-tem and cause such materials to ignite undercertain wind and weather conditions.
• Excessive starter cranking (in excess of oneminute), or an intermittently firing or floodedengine can cause three-way catalytic con-verter or exhaust system overheating.
• Remember that tampering or unauthorizedmodifications to the engine, the Engine Con-trol Module, or the vehicle may be illegal andcan cause three-way catalytic converter orexhaust system overheating. This includes:altering fuel injection settings or compo-nents, altering emission system components or location or removing components, and/orrepeated use of leaded fuel.NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxygen content of the exhaust gases. Readings are fedinto a control module that continuously monitorsengine functions and controls fuel injection. Theratio of fuel to air into the engine is continuouslyadjusted for efficient combustion to help reduceharmful emissions.

Follow applicable regulations regarding per- mitted speed and weight.
• Drive slowly when towing a trailer up a longand steep incline.
• The maximum trailer weights given only applyto altitudes up to 1000 meters (3280 feet)above sea level. At higher altitudes, enginepower (and thus the vehicle's climbing ability)is decreased due to the reduced air density,and the maximum trailer weight must there-fore be reduced. The weight of the vehicleand trailer must be decreased by 10% foreach additional 1000 m (3280 feet) or partthereof.
• Avoid driving with a trailer on inclines of morethan 12%.
• Avoid overloading and other incorrect use.
• The trailer's brakes must be balanced withthe vehicle's brakes to help ensure safestops (follow applicable local regulations).
CAUTION
•Bumper-attached trailer hitches must not be used on Volvos, nor should safetychains be attached to the bumper.
• Trailer hitches attaching to the vehiclerear axle must not be used.
• Never connect a trailer's hydraulic brakesystem directly to the vehicle brake sys-tem, nor a trailer's lighting system directlyto the vehicle lighting system. Consultyour nearest authorized Volvo retailer forcorrect installation.
• When towing a trailer, the trailer's safetychains or wire must be correctly fastenedto the attachment points provided in thetrailer hitch on the vehicle. The safetychain or wire must never be fastened toor wound around the towing ball.
NOTE
The optional detachable trailer hitch may not be available in all markets or on all models.Consult your Volvo retailer.
NOTE
Extreme weather conditions, towing a trailer, driving at high altitudes and fuel quality arefactors that significantly increase a vehicle'sfuel consumption.
Trailer weights
WARNING
Please adhere to the recommendations provi- ded for trailer weight. If the recommendationsare not followed, the vehicle and trailer maybe difficult to control during evasive maneu-vers and braking.
NOTE
The specified maximum trailer weights are those permitted by Volvo. National vehicleregulations may set additional restrictions ontrailer weight and speed. The trailer hitchesmay be certified for higher towing weightsthan the vehicle is permitted to tow.
Self-leveling suspension
*The vehicle's self-leveling system attempts to keep the vehicle at a constant level, regardless ofload (up to the maximum permitted weight).When the vehicle is stationary, the rear end of thevehicle will be slightly lowered, which is normal.
Driving in hilly terrain or hot weatherIn certain conditions, there is a risk of overheat-ing when driving with a trailer. If overheating ofthe engine and drive system is detected, a warn-ing symbol will illuminate in the instrument panelalong with a message.

imprinted on the sidewall of the tire. The last four digits 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 ageTires 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 with e.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 rotationYour 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 and wear 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 tiresWhen 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 on their 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.

8. U.S. DOT Tire Identification Number (TIN) : This begins with the letters "DOT" and
indicates that the tire meets all federalstandards. The next two numbers are thefactory code where the tire was manufac-tured, the next two are the tire size code andthe last four numbers represent the weekand year the tire was made. For example,0717 means that the tire was manufacturedduring week 7 of 2017. The numbers inbetween are marketing codes used at themanufacturer's discretion. This informationhelps a tire manufacturer identify a tire forsafety recall purposes.
9. Tire Ply Composition and Material Used :
Indicates the number of plies indicates or thenumber of layers of rubber-coated fabric inthe tire tread and sidewall. Tire manufactur-ers also must indicate the ply materials in thetire and the sidewall, which include steel,nylon, polyester, and others.
10. Maximum Load : Indicates the maximum
load in pounds and kilograms that can becarried by the tire. Refer to the vehicle's tire information placard located on the B-Pillarfor the correct tire pressure for your vehicle.

12. Maximum permissible inflation pressure: the greatest amount of air pressure that should ever be put in the tire. This limit is setby the tire manufacturer.
Speed SymbolA tire's Speed Symbol (SS) indicates the maxi-mum speed for which the tire has been certifiedand should be at least equivalent to the vehicle'stop speed. Winter tires, with or without studs, are exceptions and may use a lower SS. When winter tires areinstalled, the vehicle may not be driven fasterthan the tires' SS. The vehicle's speed should always be determined by the posted speed limit and traffic and roadconditions, not the tire's SS. The following table indicates the maximum per- missible speed for each SS.
