Tire Pressure Monitoring System (Tpms) - Volvo XC90 Owner's Manual

The tire pressure monitoring system
sensors mounted in the tire valves to check
inflation pressure levels. When the vehicle is
moving at a speed of approximately 20 mph
(30 km/h) or faster, these sensors transmit
inflation pressure data to a receiver located in
the vehicle.
USA – FCC ID: MRXG403MA4
This device complies with part 15 of the
FCC rules. Operation is subject to the fol-
lowing conditions: (1) This device may not
cause harmful interference, and (2) this
device must accept any interference
received, including interference that may
cause undesired operation.
When low inflation pressure is detected,
TPMS will light up the tire pressure warn-
ing light (also referred to as a telltale) in the
instrument panel (see page 61), and will
display a message in the text window. The
wording of this message is determined by
the degree of inflation pressure loss.

SERVICE REQUIRED
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label.
(If your vehicle has tires of a different size
than the size indicated on the vehicle placard
or tire inflation pressure label, you should
determine the proper tire inflation pressure for
those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitor-
ing system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your
tires as soon as possible, and inflate them to

the proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and
stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv-
er's responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the sys-
tem detects a malfunction, the telltale will
flash for approximately one minute and then
remain continuously illuminated. This
sequence will continue upon subsequent
vehicle start-ups as long as the malfunction
exists. When the malfunction indicator is illu-
minated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replace-
ment or alternate tires or wheels on the vehi-
cle that prevent the TPMS from functioning
