Care must be taken to replace parts properly because they could affect the performance of the
steering system and result in a driving hazard.

S

The LEXUS RX300 is equipped with SRS (Supplemental Restraint System) such as the driver
airbag and front passenger airbag. Failure to carry out service operation in the correct se-
quence could cause the SRS to unexpectedly deployed during servicing, possibly leading to
a serious accident. Before servicing (including removal or installation of parts, inspection or
replacement), be sure to read the precautionary notices in the RS section.
