Fuses and relays Lexus ES 250 / 300h / 350 (XV60), 2012–2018

Lexus unveiled its sixth-generation ES sedan at the 2012 New York International Auto Show. The lineup includes the ES 350 and the ES 300h hybrid. To redesign the ES model range, Toyota engineers incorporated their latest technical innovations. The exterior styling features Lexus’s signature design language, paired with refined powertrain options. The hybrid model utilizes a 2.5-liter 4-cylinder internal combustion engine paired with an electric motor from the latest-generation Toyota Camry Hybrid. Overall length was extended by 2.5 cm and the wheelbase by 4.5 cm, providing additional cabin space.

Electrical circuits in the Lexus ES are protected by fuses. These components are housed in distribution boxes located in the engine compartment, passenger compartment, and luggage compartment. Below are the fuse and relay box diagrams for the 6th-generation Lexus ES 250, ES 300h, and ES 350 (XV60 series; chassis codes ASV60 / GSV60 / AVV60; model years 2012–2018).
