FLAT TIRE TIRE PRESSURE MONITORING SYSTEM (TPMS) This vehicle is equipped with the Tire Pressure Monitoring System (TPMS). It monitors tire pressure of all tires. When the low tire pressure warning light is lit, one or more of your tires is significantly under-inflated. If the vehicle is being driven with low tire pressure, the TPMS will activate and warn you of it by the low tire pressure warning light (in the instrument panel) or the LOW PRESSURE information screen (on the display). This system will activate only when the vehicle is driven at speeds above 16 MPH (25 km/h). ( "Low tire pressure warning light" page 2-25) ( "TIRE PRESSURE MONITORING SYSTEM (TPMS)" page 5-3) vehicle damage could occur and may lead to an accident and could result in serious personal injury. Check the tire pressure for all four tires. Adjust the tire pressure to the recommended COLD tire pressure shown on the Tire and Loading Information label to turn the low tire pressure warning light off. If the light still illuminates while driving after adjusting the tire pressure, a tire may be flat. . When a wheel is replaced, the TPMS will not function and the low tire pressure warning light will flash for approximately 1 minute. The light will remain on after 1 minute. Contact a GT-R certified NISSAN dealer as soon as possible for tire replacement and/or system resetting. Replacing tires with those not originally specified by NISSAN could affect the proper operation of the TPMS. Do not inject any tire liquid or aerosol tire sealant into the tires, as this may cause a malfunction of the tire pressure sensors. NOTE: . You can check the pressure of all four tires on the multi function display. See the separate Multi Function Display Owner's Manual. The tires of this vehicle are filled with nitrogen gas. When the tire pressure is low, fill the tires with nitrogen. Contact a GT-R certified NISSAN dealer for information on filling the tires with nitrogen. If nitrogen is not available, compressed air may be safely used under normal driving conditions. However, NISSAN recommends refilling with nitrogen for maximum tire performance. . . WARNING . If the low tire pressure warning light illuminates or LOW PRESSURE information is displayed on the monitor screen while driving, avoid sudden steering maneuvers or abrupt braking, reduce vehicle speed, pull off the road to a safe location and stop the vehicle as soon as possible. Driving with under-inflated tires may permanently damage the tires and increase the likelihood of tire failure. Serious In case of emergency RUN-FLAT TIRES Run-flat tires are those tires that can be used temporarily if they are punctured. ( "Run-flat tires" page 8-35) Also, see the tire safety information in the Warranty Information Booklet. . . WARNING .
