11-24 Maintenance and service/Tires and wheels System resetting is necessary when the wheels are changed (for example, a switch to snow tires) and new TPMS valves are installed on the newly fitted wheels. Have this work performed by a SUBARU dealer following wheel replacement. 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 in the instrument panel will illuminate steadily after blinking for approximately one minute. When a tire is replaced, adjustments are necessary to ensure continued normal operation of the tire pressure monitoring system. As with wheel replacement, there- fore, you should have the work performed by a SUBARU dealer. 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 blink- ing for approximately one minute, you should have your Tire Pressure Monitoring System checked at a SUBARU dealer as soon as possi- ble. If this light illuminates while driving, never brake suddenly. Instead, per- form the following procedure. Other- wise an accident involving serious vehicle damage and serious perso- nal injury could occur. 1) Keep driving straight ahead while gradually reducing speed. 2) Slowly pull off the road to a safe place. If this light still illuminates while driving after adjusting the tire pres- sure, 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 pres- sure warning light will illuminate steadily after blinking for approxi- mately 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. & Tire inspection S11AV03 Check on a daily basis that the tires are free from serious damage, nails, and stones. At the same time, check the tires for abnormal wear. Contact your SUBARU dealer immediately if you find any problem. NOTE . When the wheels and tires strike curbs or are subjected to harsh treat- ment as when the vehicle is driven on a rough surface, they can suffer damage that cannot be seen with the naked eye. This type of damage does not become evident until time has passed. Try not to drive over curbs, potholes or on other rough surfaces. If doing so is unavoid- able, keep the vehicle’s speed down to a walking pace or less, and approach the curbs as squarely as possible. Also, make sure the tires are not pressed against the curb when you park the vehicle.
