These original manuals, printed by Toyota, were made to train dealer mechanics to work on the 2003 4Runner. To assist you in your service activities, these manuals give a technical explanation of the construction and operation of new mechanisms and new technology. Each of the 2 manuals is divided into three sections: (1) Model outline, which explains the vehicle to give a general understanding of its features; (2) Technical description, which explains the construction and operation of each new system and component; and (3) Appendix, with major technical specifications of the vehicle. The manuals show you a system diagram, illustrations of major components, and also charts with explanations the functions of major components, so that you can diagnose problems.
