Nissan Maxima Owners Manual: Low tire pressure warning
If the vehicle is being driven with low tire pressure, the warning light will illuminate.
A "Tire Pressure Low - Add Air" warning also appears in the vehicle information display.
When the low tire pressure warning light illuminates, you should stop and adjust the tire pressure of all four tires to the recommended COLD tire pressure shown on the Tire and Loading Information label located in the driver's door opening. The low tire pressure warning light does not automatically turn off when the tire pressure is adjusted.
After the tire is inflated to the recommended pressure, the vehicle must be driven at speeds above 16 mph (25 km/h) to activate the TPMS and turn off the low tire pressure warning light. Use a tire pressure gauge to check the tire pressure.
The "Tire Pressure Low - Add Air" warning appears each time the ignition switch is placed in the ON position as long as the low tire pressure warning light remains illuminated.
For additional information, refer to "Vehicle information display" in this section, "Tire Pressure Monitoring System (TPMS)" in the "Starting and driving" and "In case of emergency" sections of this manual.
