How do you reset tire pressure warning light on 2012 FX35

SOURCE: low tire pressure warning light

To reset (calibrate) the system: The tire inflation
monitor system can be reset two ways. With the
ignition position at ON, pull the interior lamps
control to the ON and OFF settings three times.
It can also be reset through the radio using the
following steps:
1. Turn the ignition to ACC or ON and turn the
radio off.
2. Press and hold the TUNE DISP button on the radio for
at least five seconds until SETTINGS is displayed.
3. Press the SEEK PTYPE up or down arrow to scroll
through the main menu.
4. Scroll until TIRE MON appears on the display.
5. Press the 1 PREV or 2 NEXT button to enter the
submenu. RESET will be displayed.
6. Press the TUNE DISP button to reset. A chime will
be heard to verify the new setting and DONE will be
displayed for one second.
7. Once the monitor has been reset, scroll until EXIT
appears on the display.
8. Press the DISP button to exit programming. A chime
will be heard to verify exit.
The system completes the calibration process
during driving.
The system normally takes 15 to 20 minutes of driving
in each of three speed ranges to “learn” tire pressures.
The speed ranges are 15 to 40 mph (25 to 65 km/h),
40 to 65 mph (65 to 105 km/h) and above 65 mph
(105 km/h). When learning is complete, the system
will alert you after two to eight minutes if a tire is 12 psi
(83 kPa) different from the other three tires. Detection
thresholds may be higher and detection times may be
longer on rough roads, curves and at high speeds. The
system is not capable of detection at speeds greater than
70 mph (110 km/h).

SOURCE: switch off tire pressure warning light

From the manual: First find the reset button, located below the handbrake (emergency brake) lever. The button has an "exclamation mark in a tyre" symbol.

Make sure the pressures in all tyres are what you want them to be. 35psi all 'round is good for sporty driving.

Engine off. Turn ignition to the second position (ON) but don't start the engine.

Keep the re-set button pressed until the flat tyre indicator light on the dashboard COMES ON for several seconds.

Start the engine, and drive the car normally for several minutes. This will re-set the indicator to whatever pressures you have in the tyres. Hope this helps!!

Your tire pressure is monitored by a device known as a TPMS sensor.

Tire Pressure Monitoring System is an integral part of your tire that tends to wear with age.

You need to take your vehicle to a reliable shop (I recommend Discount Tire) to have the TPMS sensor in the defective tire replaced. It's simple, and inexpensive.

I have used Discount Tire's services for almost 20 years, and have never been disappointed with their service.

You cannot reset them,Make sure that you check the pressures in the tires. The Infiniti Tire Pressure Monitoring System is designed to trip the warning light anytime the pressure in any of the tires drops below 29 psi. At 29 psi it really won't look like the tires are low. You could have one tire at 29 or 28 causing the light to stay on all the time. Check your pressures, set at 34 or 35 to be safe, or whatever pressure the tire is recommended to be. Not all infiniti vehicles with TPMS have the display that shows the pressure in each tire. If the pressures are above 29 psi, Then there could be an issue with one or more of the sensors. If you have the tires replaced you will have to have the sensors relearned at the dealer. Tire rotations do not require the same.
