Wheels and Tires: Service Precautions

PRECAUTION

1. IN CASE OF REMOVAL AND INSTALLATION OF TIRE PRESSURE MONITOR VALVE SUB-ASSEMBLY
(a) When installing a tire, make sure that the tire pressure monitor valve sub-assembly does not interfere with the tire bead so that damage to the sensor is prevented.
(b) 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.
(c) If there is air leakage, tighten the nut with a force of 4.0 Nm (41 kgf-cm, 35 in-lbf) and push the valve core 2 or 3 times to remove any dirt attached on the valve core. If there is still air leakage, replace the grommet, the washer and the nut all together.
(d) When installing the tire pressure monitor valve sub-assembly, check whether the rim, grommet, washer and nut are clean. Use a manufacturer specified cap.
(e) When putting air into the tire, first install the tire pressure valve straight onto the stem of the tire pressure monitor valve sub-assembly.

2. IN CASE OF TIRE AND WHEEL REPLACEMENT OR TIRE ROTATION
(a) 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.
(b) When tires and wheels are replaced, register the transmitter ID without fail.
