exists. When the malfunction indicator is illu-
minated, the system may not be able to
detect or signal low tire pressure as intended.
Tire Pressure Monitoring System
(TPMS) – general information
NOTE
If a malfunction occurs in the system, the
tire pressure warning light will flash for
approximately 1 minute and then remain
illuminated. Tire press. syst Service
required will be displayed.
TPMS uses 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.
System malfunctions may occur for a variety
of reasons, including the installation of
replacement or alternate tires or wheels on
the vehicle that prevent the tire pressure
monitoring system from functioning properly.

NOTE
The system indicates low tire pressure but
does not replace normal tire maintenance.
For information on correct tire pressure,
please refer to the tire inflation pressure
table (see Tire inflation – pressure table
(p. 301)), the tire inflation pressure placard
located on the driver's side B-pillar (the
structural member at the side of the vehi-
cle, at the rear of the driver's door open-
ing) or consult your Volvo retailer.
When low inflation pressure is detected or if a
sensor is not functioning properly, TPMS will
light up the tire pressure warning light (
)
(also referred to as a telltale) in the instrument
panel and will display one of the following
messages: Tire pressure low, Tire needs
air now or Tire press. syst Service
required.
WARNING
Incorrect inflation pressure could lead to
tire failure, resulting in a loss of control of
the vehicle.
