Tire Pressure Monitoring System ( TPMS ) ( U . S . -Spec . Models ) 387
vehicle is stationary . After adjusting the tire pressures , increase the vehicle speed to at least 20 mph ( 32 km / h ) to start the TPMS rechecking of the tire inflation pressures . If the tire pressures are now above the severe low pressure threshold , the low tire pressure warning light should turn off a few minutes later .
If this light still illuminates while driving after adjusting the tire pressure , a tire may have significant damage and a fast leak that causes the tire to lose air rapidly . If you have a flat tire , replace it with a spare tire as soon as possible .
. When a spare tire is mounted or a wheel rim is replaced without the original pressure sensor / transmitter being transferred , the low tire pressure warning light will illuminate steadily after blinking for approximately one minute . This indicates the TPMS is unable to monitor all four road wheels . Contact your SUBARU dealer as soon as possible for tire and sensor replacement and / or system resetting .
. When a tire is repaired with liquid sealant , the tire pressure warning valve and transmitter may not operate properly . If a liquid sealant is used , contact your nearest SUBARU dealer or other qualified service shop as soon as possible . Make sure to replace the tire pressure warning valve and transmitter when replacing the tire . You may reuse the wheel if there is no damage to it and if the sealant residue is properly cleaned off . Do not inject any tire liquid or aerosol tire sealant into the tires , as this may cause a malfunction of the tire pressure sensors . If the light illuminates steadily after blinking for approximately one minute , promptly contact a SUBARU dealer to have the system inspected .
CAUTION
Do not place metal film or any metal parts under the driver ’ s seat . This may cause poor reception of the signals from the tire pressure sensors , and the tire pressure monitoring system will not function properly .
