Overheating of engine andtransmission
In demanding driving conditions, such as drivingin mountainous areas or hot weather, there is arisk of the engine or transmission overheating,especially when carrying heavy loads.
Engine power may be temporarily limited.
Remove any auxiliary lights mounted in frontof the grille when driving in hot weather.
If the temperature in the engine's coolingsystem becomes too high, a warning symbolwill appear in the instrument panel along withthe message Engine temperature Hightemperature Stop safely. Pull over to asafe location and let the engine idle for a fewminutes to cool down.
If the message Engine temperature Hightemperature Turn off engine or Enginecoolant Level low, turn off engine is dis-played, stop the vehicle and turn off theengine.
If the transmission begins to overheat, analternative gear shifting program will beselected. An integrated protective functionwill also be activated, the warning symbol willilluminate and the message Transmissionwarm Reduce speed to lowertemperature or Transmission hot Stopsafely, wait for cooling will be displayed inthe instrument panel. Follow the recommen-dations given by reducing speed or stopping
the vehicle safely and letting the engine idlefor a few minutes to let the transmissioncool.
If the vehicle begins to overheat, the air con-ditioning may be temporarily switched off.
After a prolonged period of driving indemanding conditions, do not turn off theengine immediately after stopping.

NOTE
It is normal for the engine's cooling fan tooperate for a short time after the engine isswitched off.

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.

NOTE
The tire's load index and speed rating maynot appear on the sidewall because they arenot required by law.
7.M+S or M/S = Mud and Snow, AT = All Ter-rain, AS = All Season
8.U.S. DOT Tire Identification Number(TIN): This begins with the letters "DOT" andindicates 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 maximumload 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.
11.Treadwear, Traction, and Temperaturegrades.
12.Maximum permissible inflation pressure:the greatest amount of air pressure thatshould ever be put in the tire. This limit is setby the tire manufacturer.

Speed Symbol
A 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 exceptionsand 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 determinedby 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.
M 130 km/h (81 mph)
Q 160 km/h (100 mph)
T190 km/h (118 mph)
H 210 km/h (130 mph)
V 240 km/h (149 mph)
W 270 km/h (168 mph)
Y300 km/h (186 mph)
WARNING
The wheel and tire sizes for your Volvoare specified to meet stringent stabilityand handling requirements. Unapprovedwheel/tire size combinations can nega-tively affect your vehicle's stability andhandling.
Any damage caused by installation ofunapproved wheel/tire size combinationswill not be covered by your new vehiclewarranty. Volvo assumes no responsibilityfor death, injury, or expenses that mayresult from such installations.
