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.
