06 Maintenance and specifications Wheels and tires 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 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 Tire inflation pressure tables or consult your Volvo retailer. 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 Erasing warning messages When a low tire pressure warning message has been displayed, and the tire pressure warning light has come on: 1.

If the message is still displayed, drive the vehicle for several minutes at a speed of 20 mph (30 km/h) or faster to erase the message. 06 • Volvo recommends that TPMS sensors be fitted on all wheels used on the vehicle. Volvo does not recommend moving sensors back and forth between sets of wheels. WARNING Incorrect inflation pressure could lead to tire failure, resulting in a loss of control of the vehicle. 264
