Before a long distance trip
It is always worthwhile to have your vehiclechecked by a trained and qualified Volvo servicetechnician before driving long distances. Yourretailer will also be able to supply you with bulbs,fuses, spark plugs and wiper blades for your usein the event that problems occur.
As a minimum, the following items should bechecked before any long trip:
•Check that engine runs smoothly and thatfuel consumption and the oil level are normal.
•Before leaving on a trip, fill the fuel tank andmake sure the hybrid battery is fully charged.During the trip, make a habit of refueling reg-ularly.
•Check for fuel, oil, and fluid leakage.
•Check condition of drive belts.
•Check state of the battery's charge.
•Examine tires carefully and replace thosethat are worn. Also, check tire inflation pres-sure.
•The brakes, front wheel alignment, and steer-ing gear should be checked by a trained andqualified Volvo service technician only.
•Check all lights, including high beams.
•Reflective warning triangles are legallyrequired in some states/provinces.
•Have a word with a trained and qualifiedVolvo service technician if you intend to drive
in countries where it may be difficult toobtain the correct fuel.
•Consider your destination. If you will be driv-ing through an area where snow or ice arelikely to occur, consider using snow tires.
Driving economically
Better driving economy can be obtained bythinking ahead, avoiding rapid starts and stopsand adjusting the speed of your vehicle to imme-diate traffic conditions.

Driving economically with the XC90 T8
Twin Engine Plug-in Hybrid
Plan your driving in order to utilize the electricmotor as much as possible.
An energy-conserving driving style lowers currentconsumption from the hybrid battery and helpsincrease electric driving range.

Charging
•Charge the hybrid battery regularly using thecharging cable. Whenever possible, begin adrive with a fully charged battery.
•Check the location of charging points.
•Where possible, choose parking spaces withcharging points.

Tire sidewall designations
The following information can be found on atire's sidewall.
Federal law mandates that tire manufacturersplace standardized information on the sidewall ofall tires (see the illustration).
The vehicle has been certified with certain combi-nations of wheels and tires.
The following information is listed on the tiresidewall:
The tire designation:

NOTE
Please be aware that the following tire desig-nation is an example only and that this par-ticular tire may not be available on your vehi-cle.
1.215: the width of the tire (in millimeters)from sidewall edge to sidewall edge. Thelarger the number, the wider the tire.
2.65: The ratio of the tire's height to its widthin percent.
3.R: Radial tire (the designation RF and the
symbol indicate that the vehicle isequipped with optional self-supporting run
flat tires3.
4.15: The diameter of the wheel rim (ininches).
5.95: The tire's load index. In this example, aload index of 95 equals a maximum load of1521 lbs (690 kg).
6.H: The tire's speed rating, or the maximumspeed at which the tire is designed to bedriven for extended periods of time, carryinga permissible load for the vehicle, and withcorrect inflation pressure. For example, Hindicates a speed rating of 130 mph(210 km/h).
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 or lettersare the plant code where it was manufac-tured, the next two are the tire size code andthe last four numbers represent the weekand year the tire was built. For example,1510 means that the tire was manufacturedduring week 15 of 2010. 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 MaterialUsed: Indicates the number of plies indi-cates or the number of layers of rubber-coated fabric in the tire tread and sidewall.Tire manufacturers also must indicate the plymaterials in the tire and the sidewall, whichinclude steel, nylon, polyester, and others.
3Self-supporting run flat tires may not be available on all models

Tire direction of rotation
Incorrectly mounted tires impair the car's brakingproperties and ability to force aside rain, snowand slush.
The arrows shows the direction of rotation of the tire
•The tires with the most tread should alwaysbe on the rear axle (to help reduce the risk ofskidding).
•When switching between summer and wintertires, mark the tires to indicate where theywere mounted on the car, e.g., LF = left front,RR = right rear
•Tires with tread designed to roll in only onedirection are marked with an arrow on thesidewall.
•Contact a trained and qualified Volvo servicetechnician if you are unsure about the treaddepth.

•Tires (p. 478)Tread wear indicator
The tires have wear indicator strips runningacross or parallel to the tread.
The letters TWI are printed on the side of the tire.When approximately 1/16" (1.6 mm) is left onthe tread, these strips become visible and indi-cate that the tire should be replaced. Tires withless than 1/16" (1.6 mm) tread offer very poortraction.
When replacing worn tires, it is recommendedthat the tire be identical in type (radial) and sizeas the one being replaced. Using a tire of thesame make (manufacturer) will help preventalteration of the driving characteristics of thevehicle.

Calibrating the Tire PressureMonitoring System (TPMS)
In order for the Tire Pressure Monitoring Systemto work properly, tire pressure reference valuesmust be set correctly. This must be done eachtime wheels are changed or tire pressures aremodified.

Calibrating TPMS
To calibrate the system:
1. Switch off the engine.
2. Re-inflate the tire(s) to the correct pressure.Consult the tire pressure decal located onthe driver's side B-pillar (the structural mem-ber at the side of the vehicle, at the rear ofthe driver's door opening) or the inflationpressure table in your printed owner's man-ual supplement.
3. Start the engine.
4.Open the Car status app in the center dis-play's App view.
5.Tap Status to access Tire PressureMonitoring System.
6.Tap the calibration button.
7.Tap OK after the tire pressure in all four tireshas been checked and adjusted.
8.Drive the vehicle.
> The calibration process will be completedwhile driving and will be interrupted if thevehicle is parked and the engine isswitched off. Calibration continues auto-matically when driving resumes.
When enough data has been collected to detecta low tire pressure situation, the tires' color in thecenter display will change to green. The systemwill not give any text confirmation when calibra-tion is finished although it will state if calibrationfails. When driving with heavy loads or at sus-tained highway speeds, the tire pressure shouldbe adjusted to the recommended inflation pres-sures.
After adjusting inflation pressure, repeat steps1-8.
NOTE
Always remember to calibrate the Tire Pres-sure Monitoring System when the wheelshave been changed or the tire inflation pres-sure has been corrected according to the tirepressure decal or tire inflation pressure table.
If correct reference values have not been set,the system cannot issue low tire pressurealerts correctly.
The vehicle must be parked with the enginerunning to access the calibration button andto start the calibration process.

WARNING
The exhaust gases contain carbon monoxide,which is invisible and odorless but very poi-sonous. For this reason, always perform thecalibration procedure outdoors or in a work-shop with exhaust gas evacuation equipment.
