Section 588 (Wheel & Tire System): Precaution

WARNING: This page is about a different car, the 2004 Lexus SC 430. However, it is still accessible from the selected car via links, so may be relevant.

IN CASE OF REMOVAL AND INSTALLATION OF INFLATION PRESSURE SENSOR
1. When installing a tire, make sure that the inflation pressure sensor does not interfere with the tire bead so that damage to the sensor is prevented.
2. After completing the operation, remove the valve core to rapidly release air and check that the warning light is lit. If not, the system may be defective.
3. When replacing the inflation pressure sensor, replace it with the one which has the same identification paint color.
4. If there is air leakage, tighten it with 3.0 N.m (31 kgf.cm, 27 in.lbf). If the air is still leaking, replace the grommet together with the washer and nut.
5. When installing the tire pressure monitor valve sub-assy, check whether the rim, grommet, washer and nut are clean.
IN CASE OF TIRE AND WHEEL REPLACEMENT OR TIRE ROTATION
1. When replacing tires, be sure to check if the grommet of the tire valve is damaged or not. If so, replace the grommet together with the washer and nut.
2. When tires and wheels are replaced, register the transmitter ID without fail.
