The tire pressure monitoring system 6
pro-
vides a warning symbol in the instrument panel if pressure is too low in one or moretires.
This symbol illuminates to indicate low inflation pressure. If there is a system malfunction, the inflation pressure warning symbol
will flash for approximately one minute andthen glow steadily.
System descriptionThe tire pressure monitoring system measures differences in rotational speed between thewheels through the ABS system to determineif the tires are properly inflated. If inflationpressure in a tire is too low, its diameter (andconsequently its rotational speed) changes. Bycomparing the tires with each other, the sys-tem can determine if the pressure in one ormore tires is too low.
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. Pleasenote 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 when

556 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.

unavailable
Tire pressure system Service required
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.
