Wheel Unit Removal/Installation: Notes

1. Remove in the order indicated in the table.
2. Install in the reverse order of removal.
3. Install the valve core and valve cap, fill the tire with air.
   CAUTION:

   • A direct TPMS wheel unit has an exclusive valve cap and valve core. Always install the direct TPMS exclusive valve cap and valve core. If a valve core other than the exclusive one is installed, the wheel unit could be damaged due to rust.
   • The wheel unit air pressure stem is made of aluminum and can be damaged. Do not tilt or use excessive side force when checking the air pressure or filling a tire with air. Some tire pressure gauges and air filling nozzles have extended tips, which could bend or break the air pressure stem of the wheel unit due to the added force they can apply.
   • Do not use a tire pressure gauge with an extended tip or air injector nozzle, because it will apply excessive force to the air pressure stem of the wheel unit.
4. When replacing a wheel unit (s), register the new wheel unit ID (s). (See WHEEL UNIT ID REGISTRATION. )

NOTE:

• If the wheel unit is replaced with a new one, registration of the ID is necessary.

• If the wheel unit is replaced with a new one, the ID registration must be performed. When the ID registration is finished, the data for the new wheel unit is displayed on the M-MDS.
