Tire pressure monitoring system*

The tire pressure monitoring system1 provides a warning symbol in the instrument panel if pressure is too low in one or more tires.
SymbolExplanation
P5-1507 Symbol TPMS

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 and then glow steadily.

System description

The tire pressure monitoring system measures differences in rotational speed between the wheels through the ABS system to determine if the tires are properly inflated. If inflation pressure in a tire is too low, its diameter (and consequently its rotational speed) changes. By comparing the tires with each other, the system can determine if the pressure in one or more tires is too low.

General information about the tire pressure monitoring system

In the following description, the tire monitoring system is generally referred to as TPMS.

Each tire, including the spare (if provided)2 should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.)

As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure.

Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale.

Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended.

TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly.

Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly.

Messages in the instrument panel

If tire pressure is too low, the low tire pressure warning symbol is shown in the instrument panel along with a message.

  • Tire pressure low Check tires, calibrate after fill
  • Tire pressure system Temporarily unavailable
  • Tire pressure system Service required

To keep in mind

  • Always calibrate the system after changing wheels or adjusting tire pressure. See the tire pressure placard on the driver's side B pillar for Volvo-recommended tire pressures.
  • If you switch to a tire of another size than the factory-mounted tires, the system must be calibrated for these tires to avoid false warnings.
  • If a spare wheel2 is used, it is possible that the tire pressure monitoring system will not work correctly due to the differences between the wheels.
  • The system does not replace the need for regular tire inspection and maintenance.
  • It is not possible to deactivate the tire pressure monitoring system.

 Warning

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