pressure telltale. When the system detects a mal-function, the telltale will flash for approximatelyone minute and then remain continuously illumi-nated. This sequence will continue upon subse-quent vehicle start-ups as long as the malfunc-tion exists. When the malfunction indicator is illu-minated, the system may not be able to detect orsignal low tire pressure as intended.
TPMS malfunctions may occur for a variety ofreasons, including the installation of replacementor alternate tires or wheels on the vehicle thatprevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale afterreplacing one or more tires or wheels on yourvehicle to ensure that the replacement or alter-nate tires and wheels allow the TPMS to con-tinue to function properly.
Messages in the instrument panel
If tire pressure is too low, the low tire pressurewarning symbol is shown in the instrument panelalong with a message. Check the inflation pres-sure in the Car Status app in the center display.

To keep in mind
Always save the new inflation pressure in thesystem after changing a tire or adjusting theinflation pressure.
If you switch to a tire of another size than thefactory-mounted tires, the system must bereset by storing a new inflation pressure forthese tires to avoid false warnings.
If a spare wheel8 is used, it is possible thatthe tire pressure monitoring system will notwork 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 tire pres-sure monitoring system.
WARNING
Incorrect inflation pressure could lead totire failure, which could cause the driverto 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 system9
to function correctly, tire pressure reference val-ues must be saved correctly. To help ensure thatthe system can correctly alert the driver of lowinflation pressure, this must be done each timethe tires are changed or the inflation pressure isadjusted.
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 reset by saving the new inflation pres-sure.
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 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 vehicle must be stationary for the StorePressure button to be selectable.
6.Tap Store Pressure.
7.Tap OK to confirm that the tire pressure inall four tires has been checked and adjusted.
8.Drive the vehicle until the new inflation pres-sure has been saved.
The new inflation pressure is stored whenthe vehicle is driven at speeds over 35 km/h(22 mph).
If the vehicle's ignition is switched off beforethe new inflation pressure has been saved,the procedure must be performed again. Tohelp ensure that the new inflation pressure issaved correctly, allow the storing procedureto complete during a single operating cycle.
>If storing cannot be performed, Storingpressure unsuccessful. Try again. willbe displayed.
WARNING
The exhaust gases contain carbon monoxide,which is invisible and odorless but very poi-sonous. The procedure for saving a new infla-tion pressure must therefore always be per-formed outdoors or in a workshop withexhaust gas extraction.
