Tire Pressure Monitoring System( TPMS)( U. S.-Spec. Models)
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 place.
( 3) Check the pressure for all four tires and adjust the pressure to the COLD tire pressure shown on the tire inflation pressure label 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” FP436. 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 25 mph( 40 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, refer to“ Flat Tires” FP379.
. When a replacement 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 prop-
