HANDLING PRECAUTIONS

(a) When handling electronic parts:

(1) Avoid any impact to electronic parts such as ECUs and relays. Replace these parts with new ones if dropped or subjected to a severe blow.

(2) Do not expose any electronic parts to high temperatures or humidity.

(3) Do not touch the connector terminals in order to prevent deformation or malfunctions due to static electricity.

HANDLING PRECAUTIONS FOR SRS AIRBAG SYSTEM

CAUTION:

This vehicle is equipped with a Supplemental Restraint System (SRS). Failure to carry out service operations in the correct sequence could cause the SRS to unexpectedly deploy during servicing. This may cause a serious accident.

Before servicing (including inspection, replacement, removal and installation of parts), be sure to read the precautionary notices for Supplemental Restraint System.
