General information about the tire pressure monitoring system
In the following description, the tire monitor- ing system is generally referred to as TPMS. Each tire, including the spare (if provided)7
should be checked monthly when cold and inflated to the inflation pressure recom-mended by the vehicle manufacturer on thevehicle placard or tire inflation pressure label.(If your vehicle has tires of a different size thanthe size indicated on the vehicle placard or tireinflation pressure label, you should determinethe proper tire inflation pressure for thosetires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoringsystem (TPMS) that illuminates a low tirepressure telltale when one or more of yourtires is significantly under-inflated. Accord-ingly, when the low tire pressure telltale illumi-nates, you should stop and check your tires assoon as possible, and inflate them to theproper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tirefailure. Under-inflation also reduces fuel effi-ciency and tire tread life, and may affect thevehicle's handling and stopping ability. Please note that the TPMS is not a substitute forproper tire maintenance, and it is the driver'sresponsibility to maintain correct tire pressure,even if under-inflation has not reached thelevel to trigger illumination of the TPMS lowtire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate whenthe system is not operating properly. TheTPMS 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.
To keep in mind
Always save the new inflation pressure inthe 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 new reference values for tire inflation pressure monitoring *
In order for the tire inflation pressure moni- toring system 9
to function correctly, inflation
pressure reference values must be saved cor- rectly. To help ensure that the system cancorrectly alert the driver of low inflation pres-sure, this must be done each time the tiresare changed or the inflation pressure isadjusted.
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,
