Tyre pressure monitoring

General*
Tyre pressure monitoring, TPMS (Tyre Pres-
sure Monitoring System) warns the driver when
the pressure is too low in one or more of the
car's tyres. It uses sensors located inside the
air valve in each wheel. When the car is driven
at about 40 km/h the system detects the tyre
pressure. If the pressure is too low then a warn-
ing lamp on the instrument panel illuminates
and a message is shown on the display.
Always check the system after changing a
wheel in order to ensure that replacement
wheels work with the system.
For information on correct tyre pressures, see
page 171 and see page 172.
The TPMS system does not replace normal
tyre maintenance.
IMPORTANT
If a fault should arise in the tyre pressure
system a warning lamp on the instrument
panel will illuminate. The message

be shown. This can be for various reasons,
e.g. fitting a wheel not equipped with a sen-
sor adapted for Volvo's tyre pressure moni-
toring system.

Recommendations
Only factory fitted wheels are equipped with
TPMS sensors in the valves.
•
The temporary spare wheel does not have
this sensor.
•
If wheels without TPMS sensors are used
then TYRE PRESS SYST SERVICE

car is driven faster than 40 km/h for more
than 10 minutes.
