Have the system checked by a NISSAN dealer.  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, check the tire pressure in your tires. • Check the tire pressures (including the spare tire) often and always prior to long distance trips.  The Tire and Loading Information label contains valuable information. Please refer to section 9, "Technical and consumer information", in your Owner's Manual for the location of the Tire and Loading Information label. For more information, refer to the "Instruments and controls (section 2)", the "Starting and driving (section 5)" and the "Maintenance and do-it-yourself (section 8)" of your Owner's Manual. 4
