Tyre pressure monitoring (option)
Tyre pressure monitoring, TPMS (Tyre
Pressure 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
approximately 40 km/h the system detects
the tyre pressure. If the pressure is too low
then a warning lamp on the dashboard illumi-
nates and a message is shown in the infor-
mation 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 pressure, see
page 155 –156.
NOTE!
The TPMS system does not replace
normal tyre maintenance.
Adjusting tyre pressure monitoring
Tyre pressure monitoring can be adjusted in
order to follow Volvo’s tyre pressure recom-
mendations, when driving with a heavy load
for example.
NOTE!
The engine must not be running.
– Inflate the tyres to the required pressure.
– Select key position I or
II .
– Turn the thumbwheel on the left-hand
stalk switch until the text TYRE
PRESSURE CALIBRATION is shown in
the information display.
– Press and hold the RESET button until
the text TYRE PRESSURE CALIBRATED
is shown.
Rectifying low tyre pressure
When the message LOW TYRE PRESS.
CHECK TYRES is shown in the information
display:
– Check the tyre pressure in all four tyres.
– Inflate the tyre(s) to the correct pressure.
– Drive the car for at least 1 minute in total
at at least 40 km/h and check that the
message disappears.
Deactivating tyre pressure monitoring
NOTE!
The engine must not be running.
– Key position I or II .
– Turn the thumbwheel on the left-hand
stalk switch until the text TYRE PRESS.
SYST ON is shown in the information
display.
– Press and hold the RESET button until
the text TYRE PRESS. SYST OFF is
shown.
To reactivate the system repeat the same
steps 1 –3, so that TYRE PRESS. SYST ON
is shown in the information display.
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
REQUIRED will be shown every time the
car is driven faster than 40 km/h for more
than 10 minutes.
• Volvo recommends that TPMS sensors
are fitted to all wheels on the car (summer
and winter wheels).
• Volvo recommends that sensors are not
moved between different wheels.
IMPORTANT!
If a fault should arise in the tyre pressure
system a warning lamp on the dashboard
will illuminate. The message TYRE
PRESS. SYST SERVICE REQUIRED will
be shown. This can be for various
reasons, e.g. fitting a wheel not equipped
with a sensor adapted for Volvo’s tyre
pressure monitoring system.
WARNING!
When inflating a tyre equipped with
TPMS, hold the nozzle of the pump
directly against the valve to avoid
damaging the valve.
