Installation [11/2023 - ]: Procedure

1. Install a new grommet to the tire pressure warning valve and transmitter.
   NOTE:

   A new tire pressure warning valve and transmitter comes with a grommet installed. Make sure not to install an extra grommet.

2. Record the 7-digit number transmitter ID printed on the tire pressure warning valve and transmitter at the position shown in the illustration.

   *a	7-digit Number Transmitter ID	*b	Printed Surface

3. Insert the tire pressure warning valve and transmitter into the valve installation hole from the inside of the rim so that the printed surface can be seen.
   NOTE:

   • Check that there is no visible deformation, damage, or other abnormalities on the tire pressure warning valve and transmitter.
   • Check that there is no foreign matter on the grommet and around the rim hole.
   • If the tire pressure warning valve and transmitter is installed upside down, it may be damaged or fail to transmit signals when driving at high speeds.
4. From the outside of the rim, install the washer to the tire pressure warning valve and transmitter, which has the grommet installed. Afterward, using an 11 mm deep socket wrench, tighten the nut.

   Torque: 4.0 N.m (41 kgf/cm, 35 in.lbf) 

   NOTE:

   • No further tightening is required once the nut is tightened to the specified torque.
   • Check that there is no foreign matter on the washer and nut.
5. Set the wheel onto a mounting machine and install the lower bead. Position the main body of the tire pressure warning valve and transmitter in the shaded area shown in the illustration.
   NOTE:

   • If the tire pressure warning valve and transmitter is positioned outside this area, it will interfere with the tire bead and may be damaged.
   • If the use of lubricant is required when installing the bead, do not apply lubricant directly to the tire pressure warning valve and transmitter.

6. Install the upper bead.
   NOTE:

   Make sure that the tire bead and tool do not interfere with the main body of the tire pressure warning valve and transmitter and that it is not clamped by the bead.

7. Install a new valve core.
8. After the tire is inflated, the valve nut may be loose. Retighten the nut to the specified torque.

   Torque: 4.0 N.m (41 kgf/cm, 35 in.lbf) 

   NOTE:

   No further tightening is required once the nut is tightened to the specified torque.

9. Check for air leaks with soapy water.

   If there is air leakage, push the valve core 2 or 3 times to remove any dirt attached to the valve core. If air continues to leak, replace the grommet, washer and nut.

10. Install the tire valve cap.
