Toyota Corolla (E120): Precaution
1. Handling precautions on steering system
- care must be taken when replacing parts. Incorrect replacement may affect the performance of the steering system and result in a driving hazard.
2. Handling precautions on srs airbag system
- the vehicle 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 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
