The Infiniti Q70 was produced in 2013, 2014, 2015, 2016, 2017, 2018 and 2019 and had the model code Y51. During this time, received an update. This publication describes the fuses and relays for the Infiniti Q70, including fuse box diagrams, their locations, and photo examples. We’ll highlight the fuse responsible for the cigarette lighter.
The purpose of fuses and relays may differ from that described and depends on the year of manufacture and the level of electrical equipment in your vehicle.
