Toyota Sienna Service Manual: Precaution
1. Handling precautions on steering system
(a) Care must be taken when replacing parts. Incorrect replacement could affect the performance of the steering system and result in a driving hazard.

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 precautionary notice for the supplemental restraint system (see page rs-1).
