How to Turn Off Low Tire Light on Subaru Outbackby Alibaster Smith
Resetting the low-tire light on the Subaru Outback will turn the low-tire-pressure light off. Resetting can normally only be done properly with a diagnostic reset tool that you can buy from Subaru. The low-tire light is part of the series of service lights that are designed to warn the driver of abnormal vehicle conditions--in this case low tire pressure. The light will only stay off if the tire pressure is restored to the factory specifications.
Remove the fuse panel under the driver's steering wheel by pulling down on the panel.
Plug the electric connector on the diagnostic tool into the diagnostic plug input on the fuse panel. There is only one input that corresponds to the size of the diagnostic plug's size.
Turn the ignition to the "II" position. Wait for the lights on the diagnostic reset tool to stop blinking.
Turn the ignition key to the "I" position and remove the diagnostic reset tool plug from the fuse box. The light should go off the next time you turn on the vehicle.
