Attach chamfered washer and union nut from outside and
tighten by hand. |
Note
| If equipped handle the glued-on wheel trim carefully.
Surface slightly scratched. |
| Replace the damaged rim wheel trim. |
| 1) |
TPMS direct measuring. The wheel electronics are
installed inside the wheel on the metal valve; the tire pressure
and temperature values are transmitted and evaluated
periodically. |
| 2) |
TPMS + indirect measuring. There are no wheel
electronics installed inside the wheel. With the help of the ABS
sensors, the TPMS compares the speed and rolling circumference
of the individuals wheels. The loss of pressure is determined
indirectly. If there is a change in the tire pressure, then the
speed and the rolling circumference of wheel will also change. |
| 3) |
TPMS indirect measuring. There are no wheel
electronics installed inside the wheel. With the help of the ABS
sensors, the TPMS compares the rolling circumference of the
individual wheels. The loss of pressure is determined
indirectly. If there is a change in the tire pressure, then the
speed of the tire will also change. |
