2004 Lexus LS 430FACTORY OEM SERVICE PROCEDURE
Steering System: Precaution
- HANDLING PRECAUTIONS FOR STEERING SYSTEM
- Care must be taken when replacing parts. Incorrect replacement could affect the performance of the steering system and result in a driving hazard.
- HANDLING PRECAUTIONS FOR SRS AIRBAG SYSTEM
- The LS430 is equipped with SRS (Supplemental Restraint System) such as the driver airbag and front passenger airbag. Failure to carry out service operations 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 notice for the supplemental restraint system (see AIR BAG SAFETY PRECAUTIONS ).
