All Wheel Drive (AWD)
*
All-wheel drive, All Wheel Drive (AWD), also called four-wheel drive, means that power is dis-tributed to all four wheels, which improves trac-tion.
To achieve the best traction, power is automati- cally directed to the wheels that have the bestgrip. The system continuously calculates theneed for torque to the rear wheels, and canimmediately redistribute up to half of the engine'storque to the rear wheels. All-wheel drive also has a stabilizing effect at higher speeds. In normal driving conditions, mostof the engine's power is directed to the frontwheels. When the vehicle is stationary, all-wheeldrive is always activated in preparation for maxi-mum traction during acceleration. All-wheel drive reacts differently depending on which drive mode * is selected.

WHEELS AND TIRES

Tires
The function of the tires is to carry loads, provide traction 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 to the 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 lose control of the vehicle.
CAUTION
Some Volvo models are equipped with an Ultra 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 characteristics and 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, werecommend snow tires on all four wheels. When replacing tires, be sure that the new tires are 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 tiresOn delivery, the car is equipped with Volvo origi- nal tires that have the VOL
1
marking on the side
of 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

NOTE
The tire's load index and speed rating may not appear on the sidewall because they arenot required by law.

rain, AS = All Season
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.
11. Treadwear, Traction, and Temperaturegrades .
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.
M 130 km/h (81 mph)
Q 160 km/h (100 mph)
T 190 km/h (118 mph)
H 210 km/h (130 mph)
V 240 km/h (149 mph)
W 270 km/h (168 mph)
Y 300 km/h (186 mph)
WARNING
• The wheel and tire sizes for your Volvo are 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.

Calibrating the tire pressure
monitoring system *
In order for the tire pressure monitoring system, Tyre Pressure Monitoring System (TPMS), tofunction correctly, tire pressure reference valuesmust be set correctly. This must be done eachtime the tires are changed or the tire pressure isadjusted.
For example, when driving with a heavy load or at high speeds (over 160 km/h (100 mph)), tirepressure should be adjusted to the Volvo-recom-mended tire pressure values. The system shouldthen be recalibrated.
1. Switch off the ignition.
2. Inflate the tires to the pressure indicated on the tire pressure placard on the driver's side B pillar.
3. Start the vehicle. 4. Open the
Car status app in App view.
5.Tap TPMS.
NOTE
The car must be stationary when calibration is started.
6.Tap Calibrate.
7. Tap
OK to confirm that the tire pressure in
all four tires has been checked and adjusted. 8. Run the car until calibration is complete.
Calibration is done when the vehicle is driv- ing at a speed above 35 km/h (22 mph).
> When enough data has been collected forthe system to detect low tire pressure, the color of the tire symbols in the center dis-play will change from gray to green. Thesystem will not provide any other confir-mation that calibration has been comple-ted. If the car's ignition is switched off before calibration is complete, the tires in thecenter display change color from gray togreen upon next start-up, even if calibra-tion is not complete. Perform the calibra-tion again and allow it to complete withinthe same operating cycle to ensure thatthe calibration is carried out correctly. If start-up of calibration fails, the following message appears:
Calibration
unsuccessful. Try again..
