PRECAUTION
1. HANDLING PRECAUTIONS ON STEERING SYSTEM
(a) Care must be taken when replacing parts. Incorrect replacement they could affect the performance
of the steering system and result in a driving hazard.
2. HANDLING PRECAUTIONS ON SRS AIRBAG SYSTEM
(a) The LEXUS ES330
is equipped with SRS (Supplemental Restraint System) such as the driver airbag
and front passenger airbag. Failure to carry out service operation in correct sequence could cause the
SRS to unexpectedly deploy during servicing, possibly leading to a serious accident. Before servicing
(including removal or installation of parts, inspection or replacement), be sure to read the precaution-
ary notice for the supplemental restraint system (See page 60-1).
