XC90 AWD V8-4.4L VIN 85 B8444S (2005)
Low Tire Pressure Indicator: Service and Repair
On vehicles equipped with Tire Pressure Monitoring System (TPMS).
When a low tire pressure warning message has been displayed, and the tire pressure warning light has come on:
1. Use a tire pressure gauge to check the inflation pressure of all four tires.
2. Re-inflate the tire(s) to the correct pressure (consult the tire pressure placard or the pressure table of the owner's manual).
3. Drive the car for at least one minute at a speed of 20 mph (30 km/h) or faster.
This will erase the warning text and the warning light will go out.
