510 the system is not operating properly. The TPMS malfunction indicator is combined withthe low tire pressure telltale. When the systemdetects a malfunction, the telltale will flash forapproximately one minute and then remaincontinuously illuminated. This sequence willcontinue upon subsequent vehicle start-ups aslong as the malfunction exists. When the mal-function indicator is illuminated, the systemmay not be able to detect or signal low tirepressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replace-ment or alternate tires or wheels on the vehi-cle that prevent the TPMS from functioningproperly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels onyour vehicle to ensure that the replacement oralternate tires and wheels allow the TPMS tocontinue to function properly.
Messages in the instrument panelIf tire pressure is too low, the low tire pressurewarning symbol is shown in the instrumentpanel along with a message. Check the infla- tion pressure in the
Car Status app in the
center display.

To keep in mind
Always save the new inflation pressure in the system after changing a tire or adjust-ing the inflation pressure.
If you switch to a tire of another size thanthe factory-mounted tires, the systemmust be reset by storing a new inflationpressure for these tires to avoid falsewarnings.
If a spare wheel 8
is used, it is possible that
the tire pressure monitoring system willnot work correctly due to the differencesbetween the wheels.
The system does not replace the need forregular tire inspection and maintenance.
It is not possible to deactivate the tirepressure monitoring system.
WARNING
Incorrect inflation pressure could lead to tire failure, which could cause thedriver to lose control of the vehicle.
The system cannot predict sudden tiredamage.

Saving a new inflation pressure in the monitoring system *
In order for the tire pressure monitoring sys- tem 9
to function correctly, tire pressure refer-
ence values must be saved correctly. To help ensure that the system can correctly alert thedriver of low inflation pressure, this must bedone each time the tires are changed or theinflation pressure is adjusted.
For example, when driving with a heavy load or at high speeds (over 160 km/h (100 mph)),tire pressure should be adjusted to the Volvo-recommended tire pressure values. The sys-tem should then be reset by saving the newinflation pressure. To store the new inflation pressure as a refer- ence value in the system:
1. Switch off the ignition.
2. Inflate the tire to the correct inflation pres- sure; see the tire pressure placard on the driver's side B pillar for recommendedpressures for factory-mounted tires.
3. Start the vehicle. 4. Open the
Car Status app in App view.
5. Tap
TPMS.
NOTE
The vehicle must be stationary for theStore Pressure button to be selectable.
6.Tap Store Pressure.
7. Tap
OK to confirm that the tire pressure in
all four tires has been checked and adjusted.
8. Drive the vehicle until the new inflation pressure has been saved. The new infla-tion pressure is stored when the vehicle isdriven at speeds over 35 km/h (22 mph).
> When enough data has been collectedfor the system to detect low inflation pressure, the animation showing theprogress of the storing procedure willdisappear from the center display. Thesystem will not provide any further con-firmation that the new inflation pres-sure has been stored.
If storing cannot be performed,
Storing
pressure unsuccessful. Try again. will be
displayed. If the vehicle's ignition is switched off before the new inflation pressure has been saved, theprocedure must be performed again. To helpensure that the new inflation pressure is saved correctly, allow the storing procedure to com-plete during a single operating cycle.
WARNING
The exhaust gases contain carbon monox- ide, which is invisible and odorless but verypoisonous. The procedure for saving a newinflation pressure must therefore always beperformed outdoors or in a workshop withexhaust gas extraction.

Action when warned of low tire pressure When the inflation pressure monitoring sys- tem11
detects low inflation pressure in a tire,
immediate action is required.
If the system's indicator symbol illu- minates and the message Tire
pressure low is displayed, check
the tire pressure and inflate if neces-
sary.
1. Switch off the ignition.
2. Check the inflation pressure on all four tires using a tire pressure gauge.
3. Inflate the tire to the correct inflation pres- sure; see the tire pressure placard on the driver's side B pillar for recommendedpressures for factory-mounted tires.
4. After the inflation pressure has been adjusted, always save the new inflationpressure in the system via the center dis-play. Please be aware that the indicator symbol will not go out until the low tire pressurehas been corrected and a storing proce-dure has been started for the new inflationpressure.
NOTE
To help prevent incorrect inflation pressure, pressure should be checked when the tiresare cold. The tires are considered to becold when they have reached the sametemperature as the ambient temperature(about 3 hours after the vehicle was lastdriven). After driving for a few kilometers,the tires will warm up and the pressure willincrease.
NOTE
After inflating a tire, always replace the valve cap to help prevent valve damagecaused by gravel, dirt, etc.
Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
WARNING

Incorrect inflation pressure could lead to tire failure, which could cause thedriver to lose control of the vehicle.
The system cannot predict sudden tiredamage.

Spare wheel 13
The spare wheel is a Temporary Spare and can be used to temporarily replace a punc- tured tire on one of the vehicle's regularwheels.
The spare tire is only intended for temporary use. Replace it with a normal wheel as soon aspossible. The driving characteristics of the vehicle change and ground clearance reduces whenthe spare wheel is used. Do not wash the vehi-cle in an automatic car wash while using theTemporary Spare. The recommended tire pressure must be maintained regardless of at which position thetemporary spare wheel is used on the vehicle. If the spare wheel is damaged, a new one can be purchased from a Volvo retailer.
WARNING
Current legislation prohibits the use of the "Temporary Spare" tire other than as atemporary replacement for a puncturedtire. It must be replaced as soon as possi-ble by a standard tire. Road holding andhandling may be affected with the "Tempo-rary Spare" in use. Do not drive faster than80 km/h (50 mph).

WARNING
The vehicle must never be driven with more than one "Temporary Spare" tiremounted.
Driving with a spare wheel may alterthe driving characteristics of the vehi-cle. Replace the spare wheel with anormal wheel as soon as possible.
The spare wheel is smaller than thenormal wheel, which affects the vehi-cle's ground clearance. Watch for highcurbs and do not wash the vehicle inan automatic car wash when a sparewheel is mounted.
Follow the manufacturer's recom-mended tire inflation pressure for thespare wheel.
On all-wheel drive vehicles, the driveon the rear axle can be disconnected.
If the spare wheel is mounted on thefront axle, snow chains must not beused.
The spare wheel must not be repaired.
CAUTION
The vehicle must not be driven with wheels of different dimensions or with a spare tireother than the one that came with the vehi-cle. The use of different size wheels canseriously damage your vehicle's transmis-sion.

Tire sealing system14
The temporary tire sealing system can be used to seal a puncture in a tire or to checkand adjust the pressure in the tire. Models equipped with a spare wheel 15
do not
have the tire sealing system.
WARNING
California Proposition 65 Operating, servicing and maintaining a pas- senger vehicle can expose you to chemi-cals including engine exhaust, carbon mon-oxide, phthalates, and lead, which areknown to the State of California to causecancer and birth defects or other reproduc-tive harm.
