2007 Infiniti FX45 Owner's Manual - Page 224

Tire pressure rises and falls depending on the heat caused by the vehicle's operation and the outside temperature. Low outside temperature can lower the temperature of the air inside the tire which can cause a lower tire inflation pressure. This may cause the low tire pressure warning light to illuminate. If the warning light illuminates in low ambient temperature, check the tire pressure for all four tires. You can also check the pressure of all tires (except the spare tire) on the display screen. The order of the tire pressure figures displayed on the screen does not correspond with the actual order of the tire position. See "Tire pressure information" in the "4. Display screen, heater, air conditioner and audio systems" section. For additional information, see "Low tire pressure warning light" in the "2. Instruments and controls" section, "Tire pressure monitoring system" in the "6. In case of emergency" section. WARNING If the low tire pressure warning light illuminates 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. Serious 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 you have a flat tire, replace it with a spare tire as soon as possible. (See "Flat tire" in the "6. In case of emergency" section for changing a flat tire.) Although you can continue driving with a punctured run-flat tire (if so equipped), remember that vehicle handling stability is reduced, which could lead to an accident and personal injury. Also, driving a long distance at high speeds may damage the tires. Do not drive at speeds above 55 MPH (88 km/h) and do not drive more than 50 miles (80 km) with a punctured run-flat tire (if so equipped). The actual distance the vehicle can be driven on a flat tire depends on outside temperature, vehicle load, road conditions and other factors. Do not tow a trailer when a run-flat tire (if so equipped) is flat. When a spare tire is mounted or a wheel is replaced, tire pressure will not be indicated, the TPMS will not function and the low tire pressure warning light will flash for approximately 1 minute and remain on after the 1 minute. Contact your INFINITI dealer as soon as possible for tire replacement and/or system resetting. Replacing tires with those not originally specified by INFINITI could affect the proper operation of the TPMS. Do not inject any tire liquid or aerosol tire sealant into the tires, as this may 5-6 Starting and driving
