Fuses and relays Toyota RAV4 (XA40; 2013–2019)

Table of Contents

Most electrical circuits in the vehicle are protected by fuses. High-current components are connected via relays. Fuses and relays are installed in fuse boxes located in the passenger compartment and engine compartment.


This information applies to fourth-generation Toyota RAV4 (chassis code XA40; Toyota New MC platform) models (model years 2012–2019).
