11-22 Maintenance and service / Tires and wheels
pressure warning light does not turn off , the tire pressure monitoring system may not be functioning normally . In this event , go to a SUBARU dealer to have the system inspected as soon as possible .
While the vehicle is driven , friction between tires and the road surface causes the tires to warm up . After illumination of the low tire pressure warning light , any increase in the tire pressures caused by an increase in the outside air temperature or by an increase in the temperature in the tires can cause the low tire pressure warning light to turn off .
It may not be possible to install TPMS valves on certain wheels that are on the market . Therefore , if you change the wheels ( for example , a switch to snow tires ), use wheels that have the same part number as the standard-equipment wheels . Without four operational TPMS valve / sensors on the wheels , the TPMS will not fully function and the warning light on the combination meter will illuminate steadily after blinking for approximately one minute .
WARNING
If the low tire pressure warning light does not illuminate briefly after the ignition switch is turned on or the light illuminates steadily after blinking for approximately one minute , you should have your Tire Pressure Monitoring System checked at a SUBARU dealer as soon as possible .
If this light illuminates while driving , never brake suddenly and keep driving straight ahead while gradually reducing speed . Then slowly pull off the road to a safe place . Otherwise an accident involving serious vehicle damage and serious personal injury could occur .
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 . If the light illuminates steadily after blinking for approximately one minute , promptly contact a SUBARU dealer to have the system inspected .
! TPMS valve self-registration
S11AV0201
When the wheels are replaced ( such as when installing snow tires ) or when a new TPMS valve is mounted on a new installed wheel , you will need to perform TPMS valve self-registration . Refer to the following procedure to perform TPMS valve selfregistration .
1 . Install the wheels with TPMS valves on the vehicle .
2 . Adjust the tire pressure to the specified value . For information about the specified value of the tire pressure , refer to “ Tires ” F12-8 .
3 . Drive at speeds above 25 mph ( 40 km / h ) for at least 4 miles ( 6 km ) or until the low tire pressure warning light turns off .
NOTE
. When installing TPMS valves , use only genuine SUBARU parts . . Registration of TPMS valves can also be done at a SUBARU dealer . Consult your SUBARU dealer .
