( 5.6 ° C ) between the temperature in 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 60 ° F ( 15.6 ° C ).
Example : Tire size : 215 / 40R18 85Y Standard tire pressures : Front : 35 psi ( 240 kPa , 2.4 kgf / cm 2 ) Rear : 35 psi ( 240 kPa , 2.4 kgf / cm 2 ) Garage temperature : 60 ° F ( 15.6 ° C ) Outside temperature
Adjusted pressure [ psi ( kPa , kgf / cm 2 )] Front Rear 30 ° F ( −1 ° C ) 38 ( 260 , 2.6 ) 38 ( 260 , 2.6 )

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 25mph ( 40km / 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 .
