NVision TIRE PRESSURE MONITORING SYSTEM Owner's Manual page 15

Step 3
You are now ready to install the tire pressure sensors. Your nVISION TPMS system is designed to guide you through
this process by flashing each tire location, one by one.
It is critical that you place the sensor on the tire that corresponds to the flashing tire on the monitor. The system
will store this specific sensor location into memory. If you don't put the sensor on the corresponding tire location,
the pressure will be read and reported properly, but the display will not provide the correct tire location.
You will notice that the program mode is now displaying the Sensor Icon. This indicates that it is
looking for you to install your sensors.
The program begins with the left front tire (notice that tire is flashing on the monitor). To install the sensor, remove
the existing valve stem cover and simply screw the sensor onto the valve stem being careful not to cross thread
it. The sensor is designed to depress the dill valve inside the stem (See Illustration K). This releases the pressure
inside the tire into the sensor where it is constantly measured. Maintaining a proper seal between the sensor and
the valve stem is critical to maintaining the proper pressure in your tire.

Important: If you don't verify that you have a good seal, air will escape from the tire. To prevent an air
leak, be sure to tighten the sensor using fairly light pressure. When the sensor no longer turns, grip the
sensor firmly and turn it 1/16th of a turn further. You will feel the resistance increase. But do not over
tighten as you can strip the threads.
