My 2007 Subaru Outback has a low tire pressure indicator that stays on even after the pressure has been adjusted in all 4 tires. How do I get the light to go off? Is there a reset switch somewhere?
The Owner’s Manual should have information on how to reset the TPMS.
Have you tried looking there?
Also–on some cars, there is also a monitor attached to the spare tire. If that is the case with your car, then if the spare tire is low on air, no matter how often you take care of the other 4 tires, the monitor will still stay illuminated. The manual should mention this detail also.
