7-13. Tire pressure monitoring system( TPMS)( U. S.- spec. models)
S07AO
The tire pressure monitoring system provides the driver with a warning message when tire pressure is severely low.
The tire pressure monitoring system will activate only when the vehicle is driven at speeds above 20 mph( 32 km / h). Also, this system may not react immediately to a sudden drop in tire pressure( for example, a blow-out caused by running over a sharp object).
WARNING
. If the low tire pressure warning light illuminates while driving, never brake suddenly. Instead, perform the following procedure. Otherwise, an accident involving serious vehicle damage and serious personal injury could occur.
( 1) Keep driving straight ahead while gradually reducing speed.
( 2) Slowly pull off the road to a safe location.
( 3) Check the pressure for all four tires and adjust the pressure to the COLD tire pressure shown on the tire inflation pressure label. The tire inflation pressure label is located on the door pillar on the driver’ s side.
Even when the vehicle is driven a very short distance, the tires get warm and their pressures increase accordingly. Be sure to let the tires cool thoroughly before adjusting their pressures to the standard values shown on the tire inflation pressure label. Refer to“ Tires and wheels” FP491.
The tire pressure monitoring system does not function when the 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 1 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 sys-
