Volvo 2009 XC90 Owner's Manual page 191

NOTE
TPMS indicates low tire pressure but does
not replace normal tire maintenance. For
information on correct tire pressure, please
refer to the tables on pages 170 and 171, or
consult your Volvo retailer.
Erasing warning messages
When a low tire pressure warning message has
been displayed, and the tire pressure warning
light has come on:
•
Use a tire pressure gauge to check the
inflation pressure of all four tires.
•
Re-inflate the tire(s) to the correct pressure
(consult the tire pressure placard or the
table see page 170).
•
Drive the vehicle for several minutes at a
speed of 20 mph (30 km/h) or faster.
This will erase the warning text and the warning
light will go out.
WARNING
Incorrect inflation pressure could lead to tire
failure, resulting in a loss of control of the
vehicle.
Tire Pressure Monitoring System (TPMS) – U.S. models only
Changing wheels with TPMS
Please note the following when changing or
replacing the factory installed TPMS wheels/
tires on the vehicle:
•
Only the factory-mounted wheels are
equipped with TPMS sensors in the valves.
•
If the vehicle is equipped with a temporary
spare tire, this tire does not have a TPMS
sensor.
•
If wheels without TPMS sensors are moun-
ted on the vehicle, TIRE PRESS SYST
SERVICE REQUIRED will be displayed
each time the vehicle is driven above
25 mph (40 km/h) for 10 minutes or more.
•
Once TPMS sensors are properly installed,
the warning message should not reappear.
•
Volvo recommends that TPMS sensors be
fitted on all wheels used on the vehicle.
Volvo does not recommend moving sen-
sors back and forth between sets of
wheels.
NOTE
If a tire is changed or if the TPMS sensor is
moved to another wheel, the sensor's seal,
nut and valve core should be replaced.

CAUTION
When inflating tires with TPMS valves, press
