Calibrating tyre monitoring
*
In order for the 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. Stop the engine.
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 engine.
4. Open the Car status app in the app view.
5. Tap on Status to view tyre monitoring.
NOTE
The car must be stationary when calibration is
started.
6. Press Calibrate .
7. Tap on OK
to confirm that the tyre pressure
in all four tyres has been checked and
adjusted.
8. Drive the car.
Calibration is performed while the car is driv-
ing. Calibration is interrupted temporarily if
the engine is switched off, but is resumed
automatically when the car is driven again.
> When sufficient data has been collected
to enable the system to detect low tyre
pressure, the tyres in the centre display
change colour from grey to green. The
system provides no additional confirma-
tion that the calibration is complete.
If calibration fails, a message is shown:
Calibration unsuccessful. Please try
again.
.
NOTE
Remember that the TPMS system must be
recalibrated at each tyre change or if the tyre
pressure is adjusted. New reference values
must be stored for the system to work cor-
rectly.
