Saving A New Tyre Pressure In The Monitoring System - Volvo V90 2019 Owner's Manual

To bear in mind
Always save a new tyre pressure in the sys-
•
tem after changing a wheel or adjusting tyre
pressure.
If you change to tyres of a different size to
•
the ones fitted at the factory, the system
must be reset by storing a new tyre pressure
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.
WARNING
Incorrect tyre pressure may lead to tyre
•
failure, which could result in the driver
losing control of the car.
The system cannot indicate sudden tyre
•
damage in advance.

WHEELS AND TYRES
Saving a new tyre pressure in the
monitoring system*
In order for the system for tyre pressure monitor-
4
ing to work correctly, a reference value for the
tyre pressure must be saved. This must take
place every time the tyres are changed or the
tyre pressure is changed so that the system can
warn about low pressure correctly.
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. The
system is then reset by saving a new tyre pres-
sure.
Perform the following procedure to store a new
tyre pressure as a reference value in the system:
1. Switch off the car.
2. Inflate the tyres to the correct pressure, see
the decal on the door pillar on the driver's
side showing the recommended pressure for
factory fitted tyres.
3. Start the car.
