the garage and the temperature outside . By way of example , the following table shows the required tire pressures that correspond to various outside temperatures when the temperature in the garage is 608F ( 15.68C ).
Example :
Tire size : 235 / 45R17 97W , 245 / 40R18 97Y
Standard tire pressures : Front : 33 psi ( 230 kPa , 2.3 kgf / cm 2 ) Rear : 32 psi ( 220 kPa , 2.2 kgf / cm 2 ) Garage temperature : 608F ( 15.68C )
Outside temperature
Adjusted pressure [ psi ( kPa , kgf / cm 2 )]
Front Rear
Example : Tire size : 245 / 35R19 93Y Standard tire pressures : Front : 35 psi ( 240 kPa , 2.4 kgf / cm 2 ) Rear : 32 psi ( 220 kPa , 2.2 kgf / cm 2 ) Garage temperature : 608F ( 15.68C )

If the low tire pressure warning light illuminates when you drive the vehicle in cold outside air after adjusting the tire pressures in a warm garage , re-adjust the tire pressures using the method described above . Then , increase the vehicle speed to at least 25 mph ( 40 km / h ) and check to see that the low tire pressure warning light goes off a few minutes later . If the low tire pressure warning light does not go 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 go 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 in the instrument panel 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 . 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 .
