PRECAUTION

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

The PRIUS is equipped with SRS (Supplemental Restraint System) such as the driver airbag
and passenger airbag. Failure to carry out service operation in the 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 precautionary notices in the RS section.
