Tread wear indicatorThe tread wear indicator shows the status of the tire's tread.
The tread wear indicator is a narrow elevated strip running across the tire's longitudinal treadgrooves. The letters TWI (Tread Wear Indicator)are visible on the side of the tire. When approxi-mately 1.6 mm (1/16 inch) is left on the tread,the tread will be at the same height as the treadwear indicator. Replace the tire as soon as possi-ble. Tires with low tread offer very poor traction inrain or snow.

Tire terminology The following is a glossary of tire-related terms.
The tire suppliers may have additional markings, notes or warnings such as standard load, radialtubeless, etc.
• Tire information placard
: A placard show-
ing the OE (Original Equipment) tire sizes,recommended inflation pressure, and themaximum weight the vehicle can carry.
• Tire Identification Number (TIN)
: A number
on the sidewall of each tire providing infor-mation about the tire brand and manufactur-ing plant, tire size and date of manufacture.
• Inflation pressure
: A measure of the
amount of air in a tire.
• Standard load
: A class of P-metric or Metric
tires designed to carry a maximum load at 35psi [37 psi (2.5 bar) for Metric tires]. Increas-ing the inflation pressure beyond this pres-sure will not increase the tires load carryingcapability.
• Extra load
: A class of P-metric or Metric
tires designed to carry a heavier maximumload at 41 psi [43 psi (2.9 bar) for Metrictires]. Increasing the inflation pressurebeyond this pressure will not increase thetire's load carrying capability.
• kPa
: Kilopascal, a metric unit of air pressure.
• PSI
: Pounds per square inch, a standard unit
of air pressure. •
B-pillar
: The structural member at the side
of the vehicle behind the front door.
• Bead area of the tire
: Area of the tire next
to the rim.
• Sidewall of the tire
: Area between the bead
area and the tread.
• Tread area of the tire
: Area of the perime-
ter of the tire that contacts the road whenmounted on the vehicle.
• Rim
: The metal support (wheel) for a tire or a
tire and tube assembly upon which the tirebeads are seated.
• Maximum load rating
: a figure indicating
the maximum load in pounds and kilogramsthat can be carried by the tire. This rating isestablished by the tire manufacturer.
• Maximum permissible inflation pressure
:
the greatest amount of air pressure thatshould ever be put in the tire. This limit is setby the tire manufacturer.
• Recommended tire inflation pressure
:
inflation pressure, established by Volvo,which is based on the type of tires that aremounted on a vehicle at the factory. Thisinformation can be found on the tire inflationplacard(s) located on the driver's side B-pillarand in the tire inflation table in this chapter.
• Cold tires
: The tires are considered to be
cold when they have the same temperatureas the surrounding (ambient) air. This tem-

Tire sidewall designations
The following information can be found on a tire's sidewall.
Federal law mandates that tire manufacturers place 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 tire sidewall: 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. The larger the number, the wider the tire.
2. 65: The ratio of the tire's height to its width
in percent.
3. R: Radial tire (the designation RF and the
symbol indicate that the vehicle is
equipped with optional self-supporting run flat tires 3
.
4. 15: The diameter of the wheel rim (in
inches).
5. 95: The tire's load index. In this example, a
load index of 95 equals a maximum load of 1521 lbs (690 kg).
6. H: The tire's speed rating, or the maximum
speed 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 210 km/h(130 mph).
3 Self-supporting run flat tires may not be available on all models.

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..

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 stationary with the engine running to access the calibration but-ton and to 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.

WARNING
•The vehicle must never be driven with more than one "Temporary spare" tiremounted.
• Driving with a spare wheel may alter thedriving characteristics of the vehicle.Replace the spare wheel with a normalwheel as soon as possible.
• The spare wheel is smaller than the nor-mal wheel, which affects the vehicle'sground clearance. Watch for high curbsand do not wash the vehicle in an auto-matic car wash when a spare wheel ismounted.
• Follow the manufacturer's recommendedtire inflation pressure for the spare wheel.
• On all-wheel drive vehicles, the drive onthe rear axle can be disconnected.
• If the spare wheel is mounted on thefront axle, snow chains must not be used.
• The spare wheel must not be repaired.
CAUTION
The vehicle must not be driven with wheels of different dimensions or with a spare tire otherthan the one that came with the vehicle. Theuse of different size wheels can seriouslydamage your vehicle's transmission.
This illustration is general. The shape and design of the foam block may vary depending on vehicle model.
The spare wheel is located in the spare wheel well with the outside of the wheel facing down-ward. The same bolt runs through both the sparewheel and foam block to hold them into place.The foam block contains all tools needed tochange a wheel.

the I (On) position.
WARNING
Never stand next to a tire being inflated with the compressor. If cracks, bulges, etc. form onthe tire, switch off the compressor immedi-ately. The vehicle should not be driven. Callroadside assistance to have the vehicle towedto a workshop for inspection/replacement ofthe tire. Volvo recommends an authorizedworkshop.
NOTE
When the compressor first starts, air pressure may temporarily increase up to 6 bar (88 psi)but should decrease again after approxi-mately 30 seconds.
9. Inflate the tire for 7 minutes.
CAUTION
To help avoid overheating, the compressor should never be used for more than10 minutes at a time.
10. Switch off the compressor and check the
inflation pressure using the air pressure gauge. The inflation pressure should bebetween 1.8 bar (22 psi) and 3.5 bar(51 psi). If the inflation pressure is too high,use the air release valve to release air.
WARNING
If the bottle is not removed in the correct order, sealant could spill out.
WARNING
If pressure falls below 1.8 bar (22 psi), the hole in the tire may be too large. The vehicleshould not be driven. Call roadside assistanceto have the vehicle towed to a workshop forinspection/replacement of the tire. Volvo rec-ommends an authorized workshop.
11. Switch off the compressor and remove the electrical cable.
12. Unscrew the hose from the tire's valve and screw the valve cap back on.

LOADING, STORAGE AND PASSENGER COMPARTMENT
}}
* Option/accessory.561
Cargo compartment The vehicle has a flexible cargo compartment that makes it possible to carry and secure largeobjects.
The cargo capacity of the vehicle can be consid- erably increased by folding down the rear seatbackrests. Use the load anchoring eyelets or gro-cery bag holders to help secure objects in place, and the retractable cargo compartment cover * to
help conceal objects in the cargo compartment. The towing eyelet and tire sealing system, or the temporary spare tire *, are located under the
cargo compartment floor.

* (p. 564)
Loading recommendations
There are a number of things to consider when carrying loads in or on the vehicle.
Load-carrying capacity is determined by the vehi- cle's curb weight. The total weight of all passen-gers and any installed accessories reduces thevehicle's load-carrying capacity by the corres-ponding amount.
WARNING
The vehicle's driving characteristics change depending on the weight and position of theload.
Loading in the trunk and cargo compartment
• Position objects so they are pressing against the rear seat backrests.
• Distribute the load evenly.
• Heavy objects should be positioned as lowas possible. Avoid placing heavy objects onfolded-down seat backrests.
• Cover sharp corners with a soft cloth or simi-lar to help prevent damage to the upholstery.
• Use the load anchoring eyelets and tension-ing straps or similar to secure all objects.
WARNING
In a head-on collision at a speed of 50 km/h (30 mph), an unsecured object weighing 20kg (44 pounds) can reach a projectile weightequivalent to 1000 kg (2200 pounds).
WARNING
If objects are loaded higher than the upper edge of the side windows, leave a 10 cm (4in.) space between the objects and the win-dow. Objects placed closer to this couldimpede the function of the inflatable curtainconcealed inside the headlining.
WARNING
Always secure the load. Otherwise, it may shift during heavy braking and injure people in thevehicle. Cover sharp edges and sharp corners with something soft. Turn off the engine and apply the parking brake when loading/unloading long objects.Otherwise, it is possible for the load to reachthe gear lever or gear selector and move it toa drive position – which could cause the vehi-cle to begin rolling.
