Summary

2016 XC90 D-TPMS, Low tire pressure warning Tires/Slow leaks 21 Warning lights and chimes/Tire pressure monitoring, Low tire pressure warning If the vehicle is equipped with direct tire pressure monitoring sensors (D-TPMS) and there is a warning message in the DIM about Low tire pressure, follow advice under Service. In case there is a TPMS warning message in DIM about Low tire pressure: • Check tire pressure on the concerned wheel to confirm the symptom. Note: Refer to Tire label on B-pillar for the correct tire pressure. • If the tire pressure is low, check that there are no visible damages or screws / nails in the tire. • If the tire is defective, have it replaced. • Place some soap water between the air valve and rim to check if there are any bubbles at the air valve. Note: also push the air valve sideways to see if there are any air leaks when valve is not in centre position. • If leak/bubbles are found at the air valve, pull up the air valve one or few millimetres using tire valve tool until the air leak stops. • If air valve is defective or if the leak continues after pulling up the air valve, then check and eventually replace the air valve with a service air valve PN 31400856. • Once tires are not leaking and have the correct tire pressure, initiate a D-TPMS calibration and road test vehicle.
