Airbags
The vehicle is equipped with airbags and inflat-able curtains for the driver and passengers.
WARNING
If the airbag warning light stays on afterthe engine has started or if it illuminateswhile you are driving, have the vehicleinspected by a trained and qualified Volvoservice technician as soon as possible.
Never attempt to alter or repair any of thevehicle's safety systems yourself. Incor-rectly performed repairs to any systemcould impair function and lead to seriousinjury. All work on these systems shouldbe performed by a trained and qualifiedVolvo service technician.
WARNING
If your vehicle has become water-damaged inany way (e.g., soaked floor mats/standingwater on the floor of the vehicle), do notattempt to start the engine. This may causeairbag deployment, which could result in seri-ous injury. Volvo recommends towing thevehicle directly to an authorized Volvo work-shop.
Before attempting to tow the vehicle:
1. Switch off the ignition for at least 10minutes and disconnect the battery.
2.Follow the instructions for manually over-riding the shiftlock system.

Deployed airbags
WARNING
If any of the airbags have deployed:
Do not attempt to drive the vehicle. Haveit towed to an authorized workshop.
If necessary, seek medical attention.

WARNING
Do not use child safety seats or childbooster cushions/backrests in the frontpassenger's seat. We also recommendthat children under 140 cm (4 feet7 inches) in height who have outgrownthese devices sit in the rear seat with theseat belt fastened.
Sedan models: Keep vehicle doors andtrunk locked and keep remote controlsout of a child's reach. Unsupervised chil-dren could lock themselves in an opentrunk and risk injury. Children should betaught not to play in vehicles.
On hot days, the temperature in the vehi-cle interior can rise very quickly. Exposureto these high temperatures for even ashort period of time can cause heat-rela-ted injury or death. Small children are par-ticularly at risk. Never leave children unat-tended in a vehicle.
Child seats should always be registered.

Volvo's recommendations
Why does Volvo believe that no child should sit inthe front seat of a vehicle? It's quite simple really.A front airbag is a very powerful device designed,by law, to help protect an adult.
Because of the size of the airbag and its speedof inflation, a child should never be placed in thefront seat, even if he or she is properly belted orstrapped into a child safety seat. Volvo has beenan innovator in the field of safety since it wasfounded. And we have no intention of resting onour laurels. But we need your help. Pleaseremember to put your children in the back seat,and buckle them up.
WARNING
A child restraint should never be reused if:
The vehicle has been involved in a colli-sion, no matter how minor
Its history is unknown
It is older than the manufacturer's expira-tion date

Volvo has some very specific
recommendations
Always wear your seat belt.
Airbags are a SUPPLEMENTAL safetydevice which, when used with a three-pointseat belt can help reduce serious injuriesduring certain types of accidents. Volvo rec-ommends that you do not disconnect the air-bag system in your vehicle.
Volvo strongly recommends that everyone inthe vehicle be properly restrained.
Volvo recommends that ALL occupants(adults and children) shorter than 140 cm(4 feet 7 inches) be seated in the rear seatof any vehicle with a front passenger side air-bag.
Drive safely!

Tread wear indicator
The tread wear indicator shows the status of thetire's tread.
The tread wear indicator is a narrow elevatedstrip 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 numberon 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 theamount of air in a tire.
Standard load: A class of P-metric or Metrictires 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 Metrictires 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 unitof air pressure.
B-pillar: The structural member at the sideof the vehicle behind the front door.
Bead area of the tire: Area of the tire nextto the rim.
Sidewall of the tire: Area between the beadarea 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 atire and tube assembly upon which the tirebeads are seated.
Maximum load rating: a figure indicatingthe 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 becold when they have the same temperatureas the surrounding (ambient) air. This tem-

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 210 km/h(130 mph).
3Self-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 9
to function correctly, tire pressure reference val-ues must be set correctly. This must be doneeach time the tires are changed or the tire pres-sure is adjusted.
For example, when driving with a heavy load or athigh 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 tire to the correct inflation pres-sure; see the tire pressure placard on thedriver's side B pillar for recommended pres-sures for factory-mounted tires.
3. Start the vehicle.
4.Open the Car Status app in App view.
5.Tap TPMS.

NOTE
The car must be stationary when calibration isstarted.
6.Tap Calibrate.
7.Tap OK to confirm that the tire pressure inall 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).
If the car's ignition is switched off before cal-ibration is complete, the tires in the centerdisplay change color from gray to green uponnext start-up, even if calibration is not com-plete. Perform the calibration again and allowit to complete within the same operatingcycle to ensure that the calibration is carriedout correctly.
>When enough data has been collected forthe system to detect low tire pressure, thecolor 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 start-up of calibration fails, the followingmessage appears: Calibrationunsuccessful. Try again..

WHEELS AND TIRES
* Option/accessory.554

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 theengine 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.
