If you change to tyres of a different size to
the ones fitted at the factory, the system
must be calibrated for these tyres to avoid
false warnings.
•
If a spare wheel* is used, it is possible that
the tyre pressure monitoring system does not
work correctly due to the differences
between the wheels.
•
The system does not replace the need for
regular tyre inspection and maintenance.
•
It is not possible to switch off the tyre pres-
sure monitoring system.

WHEELS AND TYRES
Calibrate the system for tyre
pressure monitoring*
In order for the system for tyre pressure monitor-
ing, Indirect Tyre Pressure Monitoring System
(ITPMS) to work correctly, a reference value for
the tyre pressure must be determined. This must
be performed each time the tyres are changed
or the tyre pressure is changed.
For example, when driving with a heavy load or at
high speed above 160 km/h (100 mph), the tyre
pressure should be adjusted in accordance with
Volvo's recommended tyre pressure values. Fol-
lowing which, the system must be recalibrated.
1. Switch off the car.
2. Inflate the tyres to the desired pressure in
accordance with the tyre pressure label on
the door pillar on the driver's side.
3. Start the car.
4. Open the Car status
app in the app view.
