07 Wheels and tires Tire Pressure Monitoring System (TPMS) - U.S. models only 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. Changing wheels with TPMS Please note the following when changing or replacing the factory installed TPMS wheels/ tires on the vehicle: CAUTION When inflating tires with TPMS valves, press the pump's mouthpiece straight onto the valve to help avoid bending or otherwise damaging the valve. • 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: spare tire, this tire does not have a TPMS sensor. • If wheels without TPMS sensors are mounted 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. • 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). • Once TPMS sensors are properly installed, the warning message should not reappear. • 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. • 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. 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. 07 191
