Volvo XC90 Automobile User Manual


 
2007 Volvo XC90
Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the
inflation pressure recommended 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 monitoring system
(TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-
inflated. Accordingly, when the low tire pressure telltale illuminates, 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 driver'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 system 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 illuminated, 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 replacement or alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
NOTE:
TPMS indicates low tire pressure but does not replace normal tire maintenance. For information on
correct tire pressure, please refer to the table on page 154, 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:
pg. 157 Wheels and tires
Tire Pressure Monitoring System (TPMS) - option
- 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 on page 154).
